PPSM (Ports, Protocols, Services Management) Ultimate Guide

Ports, Protocols, and Services Management (PPSM) is a crucial practice for securing network traffic in modern organizations. If mismanaged, something as simple as an open port can become a gateway for attackers. In fact, as of 2025, open ports remain “among the most exploited security flaws” due to inconsistent management across enterprises securityscorecard.com.

This ultimate guide will explain what PPSM is, why PPSM matters for cybersecurity, how PPSM works (including its processes and categories), and best practices to implement it. We’ll also answer frequently asked questions. Let’s dive in and lock down those ports and protocols.

PPSM stands for Ports, Protocols, and Services Management. It is an organized, comprehensive approach to controlling how network ports, communication protocols, and services are used in your environment. Originally developed as a formal program by the U.S. Department of Defense, PPSM’s objective is to ensure that all networked applications, services, and the ports/protocols they rely on are properly registered, controlled, and regulated disa.mil. In simpler terms, PPSM acts as a gatekeeper for network traffic – it defines which digital “doors” (ports) are open or closed, which “languages” (protocols) are allowed to speak, and which services can run, all in the name of security and interoperability.

Understanding the components (PPS): The term Ports, Protocols, and Services (PPS) refers to the elements of network communication that PPSM governs:

Port: A port is like a channel or door on a device used for network communications. Ports are identified by numbers (e.g., port 80 for HTTP, 443 for HTTPS) and allow specific types of data to flow in and out. An open port means the port is listening and can accept network connections, whereas a closed port is not available to outside traffic en.wikipedia.org en.wikipedia.org. Misconfiguring ports (leaving unnecessary ones open) can expose services to attack.
Protocol: A protocol is a set of rules for how data is transmitted and received. Examples include HTTP, HTTPS, FTP, SSH, and so on. Protocols define the format and process of communication. Some protocols are more secure than others (compare HTTPS vs. HTTP, or SSH vs. Telnet). PPSM keeps track of which protocols are in use and ensures they meet security standards.
Service: A service (or data service/application) is the actual application or function running on a system that uses specific protocols and ports. For instance, a web server is a service that typically uses the HTTP/HTTPS protocol on port 80/443. PPSM requires documenting each service and its associated protocols/ports.

By managing these three components together, PPSM provides a holistic view of network traffic. It ensures that every port/protocol/service combination in use is known, documented, and vetted.

Official definition: According to DoD standards, PPSM was “created to ensure that applications, protocols, and services (with their associated ports) used in DoD information systems are registered, controlled, and regulated.” disa.mil In practice, this means if you want to run a service on your network (say a new database or web application), you must go through a PPSM process: register the service and its ports/protocols in a central registry, assess its security, categorize its risk, and implement controls to either allow, restrict, or block it as appropriate. While PPSM has its roots in government security, the same principles apply to any enterprise network: know what’s running on your network and limit it to what’s necessary and safe.

Why PPSM Matters for Secure Network Traffic

Why should you care about PPSM? In a word: security. Every open port or unrestricted protocol is a potential doorway for attackers. Implementing PPSM significantly reduces your attack surface by eliminating unnecessary entry points and tightening control over allowed traffic. Here are key reasons PPSM matters:

Prevents Common Attack Vectors: Attackers constantly scan for open or poorly secured ports as easy targets securityscorecard.com. For example, the notorious WannaCry ransomware outbreak exploited a vulnerability on port 445 (SMB file-sharing) – a port that, if unnecessary, should be closed or tightly restricted securityscorecard.com. By using PPSM to block or harden high-risk ports (like SMB, Telnet, RDP) and services, you preempt many attacks. In 2025, misconfigured open ports are still a major risk because many organizations haven’t consistently locked them down securityscorecard.com. PPSM enforces a discipline of closing ports you don’t need and securing the ones you do, effectively cutting off many common intrusion paths.
Reduces Breaches and Data Exposures: A recent analysis found that organizations had an average of 131 vulnerable, exposed ports accessible – a 27% increase over the prior year securityboulevard.com. Each exposed port is a possible breach. PPSM ensures those exposures are identified and addressed. Simply put, fewer open ports and approved protocols only means fewer opportunities for cybercriminals. It’s a fundamental part of “least privilege” for networks – only allow what’s needed. (Notably, this principle is echoed in frameworks like NIST SP 800-53’s control CM-7 on Least Functionality, which urges organizations to “provide only essential capabilities” and restrict all unnecessary ports/protocols public.cyber.mil.)
Ensures Compliance and Standards Adherence: If your organization must meet regulatory or security framework requirements, PPSM is often expected. In U.S. government environments (e.g., DoD), it’s mandatory to register and manage all ports and services – a requirement in place since 2004 public.cyber.mil. Even outside of DoD, the concept aligns with best practices such as those in ISO 27001, NIST Cybersecurity Framework, and others that call for an inventory of network services and limiting network access. A formal PPSM program demonstrates that you are controlling network traffic in a structured way (important for audits and assessments).
Improves System Interoperability and Deployment Efficiency: Beyond security, there are operational benefits. When every system’s ports and protocols are cataloged and standardized, it reduces misconfigurations and integration issues. The DoD found that compliance with PPSM “reduces development time and cost, increases security, speeds up certification and accreditation, enhances interoperability across the department, and speeds deployment of new systems.” mitre.org In other words, knowing exactly which services are allowed to talk (and blocking those that shouldn’t) prevents those last-minute firefights with firewalls and incompatible settings. Your network runs smoother when only well-defined, approved traffic is flowing.
Facilitates Zero Trust and Network Segmentation Strategies: PPSM complements modern security architectures like Zero Trust (which assumes no traffic is trusted by default) and network segmentation. By regulating ports and protocols, PPSM helps enforce the “default deny, allow by exception” model that Zero Trust recommends. It also provides a clear blueprint of what connections should exist, which is invaluable when segmenting networks into secure zones. In essence, PPSM provides the ruleset for your firewall policies and access control lists – if you’ve documented that only certain services are needed between segment A and B, you can confidently block everything else. This tight control limits lateral movement and contains breaches, since unauthorized traffic simply isn’t permitted to flow.

In summary, PPSM matters because it is one of the most effective ways to secure network traffic at a fundamental level. It forces you to be intentional about network communications – to justify each open port and enabled protocol – and by doing so, slams doors in the face of would-be intruders. When done properly, PPSM gives you confidence that the traffic moving in, out, and across your networks is only what you’ve explicitly allowed (and that you have security measures in place for each allowed service).

How PPSM Works: Process and Categories

So, how do you actually do Ports, Protocols, and Services Management? PPSM can be thought of as a process with distinct steps, as well as a system of categorizing network services by risk. Whether you’re formalizing it for compliance or just adopting the best practice, the workflow generally looks like this:

Discover and Inventory – Identify all Ports, Protocols, and Services in use. Before you can manage your PPS, you need to know what you have. This means scanning your networks and documenting every active port, the protocol running on it, and the service or application using it. Many organizations maintain a centralized PPSM Registry (essentially a database or spreadsheet) that lists each approved service and its associated protocol/port. (In DoD, registering in the official PPSM Registry is required by policypublic.cyber.mil.) During this step, you should also identify the network boundaries each service crosses – is it internal only, or does it traverse to an external network or the internet? Understanding the exposure level is key to assessing risk.
Assess Vulnerabilities and Risk – Analyze each PPS for security risk. For every port/protocol/service identified, determine its known vulnerabilities or inherent risks. For example, is the protocol known to be secure (HTTPS with encryption) or not (Telnet sending data in cleartext)? Is the service hardened and up-to-date, or does it have a history of exploits? Many organizations leverage existing sources here, such as vulnerability databases or, in the DoD’s case, a Vulnerability Assessment (VA) process by the PPSM office. If a service isn’t already on an approved list (often called the Category Assurance List, or CAL), a deeper review is done. The goal is to find any weaknesses that an attacker could exploit via that port or protocol, and to identify countermeasures (e.g. require encryption, apply a patch, limit the source IPs that can connect, etc.).
Assign an Assurance Category – Classify the PPS based on its risk level and required controls. After assessment, each port/protocol/service is given an assurance category. This category indicates how trustworthy or risky that communication is, and thus what restrictions apply. In formal PPSM programs, there are typically three categories, often color-coded:
- Category Green (High Assurance): Low-risk or fully vetted services that are recommended or broadly allowed. These are protocols with strong security and a low potential to cause damage if used properly. (Think of modern, well-secured protocols like HTTPS, which, with proper configuration, are considered safe.)
- Category Yellow (Medium Assurance): Medium-risk services that are allowed but with restrictions/mitigations. These might be legacy protocols or niche services that can be used if specific security measures are in place. (For example, FTP might be permitted within a closed network for a legacy system but only with additional network monitoring or only for a short duration.)
- Category Red (Low Assurance): High-risk services that are strongly discouraged or banned by default due to their vulnerability or potential for misusemitre.org. These are protocols known to be insecure or unnecessary in most cases. (Think of Telnet or unauthenticated SNMP – they’re obsolete or dangerous, and if you must use them, you’ll likely need a formal waiver or exception.)
These assurance categories are typically documented in the Category Assurance List (CAL) – which is essentially the master list of all reviewed PPS and their assigned category (often including the allowed network boundaries for each). The CAL is a quick reference for administrators to know, for instance, that port X with protocol Y is a Category Red (banned), whereas port A with protocol B is Category Green (allowed)disa.mil. If something is Category Red and you still need to use it, an exception process is required where a risk decision authority evaluates if an exception can be grantedesd.whs.mil jcs.mil.
Implement Controls (Regulate) – Apply the necessary controls to allow or block traffic per the categories. Once you have categories:
- Allow high-assurance (Green) services, but still enforce best practices on them (e.g., ensure they are properly configured). For medium (Yellow) services, allow with restrictions – for instance, only allow them between specific systems, or only if encrypted or only within certain time windows. For low-assurance (Red) services, block them by default at your firewalls or routers. Essentially, you configure your network devices (firewalls, intrusion prevention systems, access control lists, etc.) to enforce the policy: Only traffic matching approved ports/protocols is let through; everything else is dropped. This is where PPSM guidance turns into reality on your network – often by updating firewall rule sets or router ACLs to match the Category Assurance List.
Illustration: PPSM in action – a firewall allowing authorized (green arrow) traffic on an approved port (e.g., port 443 HTTPS), while blocking unauthorized (red “X”) traffic on a banned port (e.g., port 445 SMB). By default, all ports are denied unless explicitly allowed, which is a core PPSM principle.

As the diagram suggests, a common best practice is a “default deny” stance: close all ports by default and only open those that have been reviewed and approved. This concept is echoed in expert recommendations: “Close all ports by default. Allow only what is necessary.”securityscorecard.com. PPSM helps you systematically decide what is necessary and ensure everything else is shut down.
Document and Register – Record the decisions for accountability. In parallel with implementing controls, ensure that your PPSM registry or documentation is updated. Each service should have an entry noting its approved usage: the port, protocol, service name, system(s) using it, the category assigned, and any special mitigations or expiration (if an exception was granted). Keeping this registry up to date is critical – it serves as a reference for network engineers and auditors, and it helps when maintaining or troubleshooting the network. In DoD’s official process, systems must be “declared” and registered with all their PPS details, and the registration is used to verify compliancepublic.cyber.mil public.cyber.mil. For a private company, the “registry” might simply be an internal spreadsheet or database – the key is that it’s centrally managed and reviewed.
Monitor and Update Continuously – PPSM is not a one-time task; it’s ongoing. Networks evolve: new applications come online, old services are retired, and threat landscapes change (a protocol once considered safe might become vulnerable due to a new exploit). Thus, continuous monitoring is essential. Set up routine port scans and traffic monitoring to catch any unexpected open ports or services. If something not in your registry is detected on the network, investigate and either formally add it through the PPSM process or eliminate it. Also monitor the usage of approved services – ensure they’re not being abused. Security tools can help log and alert on unusual activity (e.g., a surge of traffic on an admin port). “Monitor everything” is a mantra here: enable logging to detect brute-force attempts or anomalies on your allowed portssecurityscorecard.com. Additionally, keep an eye on vulnerability disclosures; if a new vulnerability hits a protocol you use, you may need to reassess its category or apply new controls. Regular audits (e.g., quarterly reviews of the PPSM registry vs. actual network scans) will keep the program effective and up-to-date.

The PPSM lifecycle can be visualized as a continuous cycle: Discover → Assess → Categorize → Control → Monitor → (back to Discover new changes). When integrating PPSM in large environments, organizations often establish a formal PPSM Committee or Change Control Board (CCB) to evaluate new requests (e.g., a project needs to open a new port). The request goes to the PPSM team, which performs the assessment and assigns a category, then updates the CAL and registry. Only after approval would the network team implement the firewall change. This governance ensures no one can bypass the process. As a rule of thumb, any new network service must go through PPSM review before being allowed to communicate. This might sound cumbersome, but it’s far easier to address security up front than to respond to a breach later.

Network boundaries consideration: PPSM especially focuses on services that cross network boundaries (for instance, from a private network to the internet, or between two segmented internal networks). Those are highest risk and most regulated. Services that stay entirely internal within a secure enclave are still managed, but sometimes with a slightly different process (e.g., an abbreviated assessment or a local approval, as seen with the concept of Component Local Services Assessments (CLSA) in DoDpublic.cyber.mil). The logic is straightforward: if a service never leaves a secured zone and poses limited impact, you handle it accordingly; if it opens a path through your perimeter, it gets strict scrutiny. Regardless, every service is documented.

PPSM Best Practices for Implementation

Implementing PPSM effectively requires not just following the process once, but establishing ongoing habits and controls. Here are some best practices to ensure your Ports, Protocols, and Services Management truly secures your network traffic:

Adopt a “Default Deny” Firewall Posture: Configure your firewalls and routers to block all traffic by default, then create allow rules only for the specific ports/protocols/services that have been approved. This principle is the foundation of PPSM and Zero Trust networking. By not trusting any port by default, you eliminate a vast number of threats. Remember the expert advice: close all ports unless you explicitly need them opensecurityscorecard.com. This may require re-engineering some legacy open network setups, but it immensely strengthens security.
Use Secure Protocols and Modern Services: Wherever possible, replace insecure or outdated protocols with secure alternatives. For example, use SSH instead of Telnet, SFTP instead of FTP, and HTTPS instead of HTTP for web servicessecurityscorecard.com. Older protocols often lack encryption or have known vulnerabilities. Modern equivalents provide encryption and better authentication. If you must use an older service for compatibility reasons, isolate it and monitor it heavily. Additionally, prefer well-known standard ports (rather than arbitrary high ports) for services – this makes management easier and avoids confusion. A key PPSM goal is to standardize network traffic on a set of known-good, well-protected channels.
Document Everything (and Keep Documentation Current): Maintain a comprehensive PPSM registry or inventory and ensure it’s updated whenever changes occur. This document should list all allowed ports, protocols, and services, along with owners, justification (why it’s needed), and the date of approval or review. Treat this as a living document – something your network and security teams refer to regularly. It can be helpful to also document what is not allowed (for instance, some teams include a list of explicitly banned services for clarity). Good documentation enables easier audits, smoother handoffs to new team members, and faster troubleshooting. It also ensures accountability – if someone wants to open a new port, they need to go through the documentation process.
Regularly Audit and Scan Your Network: Schedule routine scans (using tools like Nmap or vulnerability scanners) to find open ports across your environment, and verify that each open port is accounted for in your PPSM registry. If you discover an unapproved service running, treat it as an incident: investigate and close it or formally register and secure it. Attackers are scanning yousecurityscorecard.com, so you need to scan yourself first. Also review firewall configurations and compare them against the approved list (a mismatched rule allowing something not on the list should be corrected). Consider penetration tests focused on port/protocol misuse to ensure nothing slips through the cracks.
Apply Least Functionality & Network Segmentation: As part of PPSM, remove or disable any services and ports that are not needed on systems. Many operating systems come with services listening on ports that your use-case might not require – shut those off to harden the system. This ties into the concept of least functionality (only run what is necessary) which is so important it’s a formal control (CM-7) in security frameworkspublic.cyber.mil. Additionally, use network segmentation to your advantage: group systems by trust level and function, and strictly limit what ports can communicate between segments. For example, user workstations likely never need to directly talk to a database server on its port – so don’t let them. Use PPSM data to design segmentation rules. If an attacker does breach one segment, the lack of unrestricted port access to other segments will stop them from freely moving around.
Plan for Exceptions with Compensating Controls: There will be times when a risky port or protocol (Category Red in PPSM terms) is still needed for a valid reason. In these cases, establish a formal exception process. Require documentation of why it’s needed, who approves it, and what extra security measures will be in place. For instance, you might only allow that service from a specific IP range or within a VPN, and you might require additional monitoring or more frequent vulnerability assessments on it. Exceptions should be temporary whenever possible – plan to migrate off the risky service. PPSM best practice is to review exceptions periodically (e.g., every 6 months) to see if they can be closed.
Continuous Monitoring and Alerts: Don’t just set rules and forget them. Implement continuous monitoring on critical or exposed services. For example, if you allow SSH (port 22) from the internet to a server, you should have intrusion detection or logging that alerts on suspicious attempts (e.g., multiple failed logins or unusual commands). Leverage your Security Information and Event Management (SIEM) to correlate port activity with threat intelligence. Monitoring will help catch misconfigurations or abuses early. As the SecurityScorecard research notes, having logging in place helps detect things like brute-force attacks or anomaly spikes on your portssecurityscorecard.com. Essentially, trust but verify – if you must trust a port to be open, verify its usage continuously.
Educate Your Team and Integrate PPSM into Change Management: Finally, ensure that all relevant teams (network engineers, system admins, developers, etc.) are aware of PPSM policies. They should know that no new service goes live without registering and getting approval. Integrate PPSM checks into your change management process – e.g., when someone requests a firewall change, require a reference to the PPSM approval or registry ID. This way, PPSM becomes a normal part of deploying new applications. By building awareness, you also crowdsource the policing: teams will notify the security group when they plan something new, because they know it’s required and ultimately in their interest for security.

Following these best practices will make your PPSM program robust and effective. It transforms PPSM from a check-the-box exercise into a proactive shield for your network. The result is a network environment where every open port is a conscious decision that has been vetted for necessity and security – no accidental exposures, no forgotten services lurking, and a much harder target for attackers.

Q: What is the PPSM Registry?

A: The PPSM Registry is a centralized repository (database or list) where all the organization's allowed Ports, Protocols, and Services are recorded. Think of it as a master list of "what's permitted on our network". For each entry, it typically includes details like the service name, description, port number, protocol, IP address or system that use it, and it's assurance category or approval status. In the U.S. DoD context, the PPSM Registry's is an official database that programs must update whenever the use a new port or service, and registration has been mandatory since 2004 for all the DoD systems public.cyber.mil. For a private company, your PPSM Registry can be an internal document or tool. The purpose to have one authoritative source to consult above network traffic - if it's not the registry, it shouldn't be running. This helps with audits, troubleshooting, and ensuring compliance with your security policy.

Q: Is PPSM only for government or military networks?

A: Not at all. While PPSM as a formal term and program comes from the U.S. Department of Defense, the underlying principle – controlling ports, protocols, and services – is universal to good cybersecurity. Any organization that wants to secure its network can adopt PPSM practices. In essence, PPSM is just a structured way to implement network “least privilege” and hygiene. Corporate IT departments, critical infrastructure providers, and others are increasingly doing similar port/protocol management under different names (like “application whitelisting for network traffic” or simply rigorous firewall management). If you operate under frameworks like NIST, ISO 27001, PCI-DSS, etc., you’ll find requirements to inventory services and close unnecessary ports, which is PPSM in spirit. So even if you’re not mandated by a PPSM instruction, adopting it will strengthen your security and align with industry best practices. It’s about knowing and limiting what's running on your network, which is beneficial for everyone.

Q: How does PPSM relate to my firewall and IDS/IPS?

A: Think of PPSM as the strategy and policy, and firewalls/IDS as the enforcement tools. PPSM tells you what should be allowed or blocked; your firewall is how you enforce those decisions. For example, after a PPSM review you might decide “We will allow HTTPS (443) to these web servers, and block Telnet (23) everywhere.” You would then implement that via firewall rules – allow 443 to those IPs, add a rule to deny any Telnet traffic, etc. Intrusion Detection/Prevention Systems (IDS/IPS) and monitoring tools then watch the allowed traffic for any signs of misuse (like an attack over port 443) and can alert or block as needed. Without PPSM, a firewall can still block known bad ports, but you might not have a comprehensive or up-to-date policy behind it. PPSM provides the intelligence and rationale for your firewall configurations. One way to integrate them is to make the Category Assurance List directly inform your firewall rule base (many government networks do this – if something is Category Red on the CAL, it’s in the firewall deny list). In summary, PPSM is the plan, and network security devices are the execution. You need both working together: PPSM to decide what’s allowed, and firewalls/IPS to implement those decisions in real time.

Q: What is the Category Assurance List (CAL)?

A: The Category Assurance List (CAL) is a key output of the PPSM program – it’s essentially a published list of protocols, services, and ports with their assigned assurance categories. It assures (to users and administrators) that a given service was evaluated and what its risk level is. For example, the CAL might list something like: “HTTPS (TCP 443) – Category Green (Allowed); Telnet (TCP 23) – Category Red (Banned)”. Administrators use the CAL as a reference when configuring networks: anything not on the CAL is by default not allowed until it’s assessed. The CAL is usually maintained by the central PPSM authority (like the PPSM office in DoD) and updated regularly as new services are evaluated or old ones change status. It’s worth noting that the DoD CAL is Controlled Unclassified Information, meaning it’s not publicly available in detail (since it could be a roadmap for adversaries if they knew exactly what’s allowed). However, the general concept is that your organization should have its own CAL or approved protocol list – even if it’s not called that. This list helps enforce consistency. If a developer wants to use a new protocol that’s not on the list, it triggers a review. In short, the CAL = “our allowed services roster” combined with “risk ratings.” It’s a cornerstone of PPSM.

Q: How often should we review and update PPSM information?

A: PPSM is an ongoing effort. Reviews should be continuous or at least periodic. A good practice is to do a major review annually (to catch any drift in what’s running on the network vs. what’s in the documentation) and smaller check-ups quarterly. However, certain triggers should prompt an immediate update: for instance, if a new project is deploying a system, include PPSM in the deployment checklist; if a major vulnerability is announced for a protocol you use, re-evaluate its status (you might move it from allowed to disallowed until patched, for example). Also review whenever network topology changes or mergers/acquisitions bring in new infrastructure. Automation can help – some organizations integrate their asset management or CI/CD pipelines with PPSM, so whenever a new server comes online or a container is deployed, it checks against the allowed ports list. In summary, treat PPSM as a living process. The threats and your environment evolve, so should your PPSM data. A stale PPSM registry (one that doesn’t reflect reality) is almost as bad as none at all, because it can give a false sense of security. Keep it current, and it will continue to protect you effectively.

Q: Does implementing PPSM impact network performance or agility?

A: When done properly, PPSM should not significantly impact performance – it’s mainly a policy and configuration matter. The actual network enforcement (like firewall filtering) is something you likely already have in place; PPSM just fine-tunes it. In terms of agility, there is a trade-off: PPSM introduces a bit of overhead in that teams must get approvals for new ports/protocols. This can be managed by streamlining the review process (e.g., define clear criteria for common requests, maintain a readily accessible allowed list so people can design within it). Many find that this “speed bump” is actually beneficial, as it forces better planning and consideration of security early in projects rather than as an afterthought. Also, by preventing the deployment of insecure services, PPSM can save you from incidents that would cause far more downtime and emergency effort. There is an initial lift to set up a PPSM program – inventorying everything and establishing the registry – but once in place, it becomes part of the routine. Some teams even report that PPSM speeds up some aspects of deployment because developers know exactly what protocols are approved and design accordingly, avoiding back-and-forth with security later. Overall, the security gained far outweighs any minor delays in requesting approvals.

Conclusion and Next Steps

In conclusion, PPSM (Ports, Protocols, and Services Management) is one of the most powerful strategies to secure your network traffic. By systematically cataloging what’s in use, evaluating its safety, and controlling its usage, you drastically reduce your network’s exposure to threats. PPSM transforms the chaotic landscape of network ports and protocols into a well-guarded terrain where every open port is there for a good reason and is properly defended. This comprehensive approach not only bolsters security but also brings order and clarity to your IT environment (no more guessing what a random open port is for – you’ll know!).

To get started, begin with the basics: what’s open, what’s it for, do we need it? Then incrementally apply the PPSM process. Even if you can’t do it all overnight, each step – each unnecessary port closed or each new service properly reviewed – is a measurable improvement in security. Remember, attackers are continuously probing for any crack in the defenses securityscorecard.com; PPSM helps ensure those cracks are sealed.

Finally, consider integrating PPSM with your broader security program. It goes hand-in-hand with vulnerability management, change control, and architectural review. Make it a habit for your teams to think about ports and protocols early in any project. With this ultimate guide, you have the knowledge to implement PPSM effectively.

Secure network traffic isn’t a one-time project, but an ongoing commitment – and PPSM is your blueprint for that commitment. Stick to it, keep refining, and you’ll stay a step ahead of threats while keeping your organization’s connectivity running smoothly and safely.
