The 5 Levels of CMMC

May 5, 2020 | Cyber Security, IT News

Time is ticking on adopting the security postures required by the Cybersecurity Maturity Model Certification (CMMC). We realize that the requirements can feel overwhelming, but like most problems, they can be broken down into parts. And it just so happens that CMMC is divided into five levels, each tier building upon the previous one. The more of these levels your organization achieves, the better you will look when vying for a DoD contract. Here’s a closer look at what they are.

CMMC: Level 1 – Basic Cyber Hygiene

While Level 1 of CMMC may be considered “basic” cyber hygiene, it’s comprised of 35 practices as of the latest CMMC revision (and at the time of writing this article). This covers everything from things like password strength to locking the door to your office when you leave for the day.

CMMC: Level 2 – Intermediate Cyber Hygiene

While considered more of a stepping stone for protecting CUI, most companies — particularly those with managed service providers handling their basic IT — are mostly there already. There should be little to no extra costs for a company to reach Level 2. This is yet another example of why having an MSSP can be invaluable throughout this process. At the time of writing, Level 2 contains 115 practices.

CMMC: Level 3 – Good Cyber Hygiene

The 5 Levels of CMMCOne of the major differences between CMMC Level 2 and CMMC Level 3 is on-going security management. Just because an organization has purchased security solutions, that doesn’t necessarily mean they are properly in place or correctly implemented. There are 91 practices to adopt in Level 3. If an organization handling CUI has the practices of CMMC Level 3 in place at all times, they become a difficult target for malicious actors.

CMMC: Level 4 – Proactive

“Proactive” is exactly what it sounds like. At CMMC Level 4, an organization has a substantial and proactive cybersecurity program. The organization has the capability to adapt their protection and sustainment activities to address the changing tactics, techniques, and procedures, or TTPs, in use by APTs. For process maturity, a CMMC Level 4 organization is expected to review and document activities for effectiveness and inform high-level management of any issues. In total, Level 4 contains 95 practices.

CMMC: Level 5 – Advanced / Progressive

CMMC Level 5 is all about standardizing and optimizing. It mainly focuses on the protection of CUI from APTs. The 34 additional practices that make up Level 5 increase the depth and sophistication of cybersecurity capabilities and include the need for subject matter experts.

While the DoD is not asking small to medium size businesses to implement Fort Knox’s level of security, they are requiring adequate security and good cyber hygiene. That’s what the Cybersecurity Maturity Model Certification is all about. And that’s exactly why you should turn to the experts for help in adopting it. That’s where we come in.

Backups Alone Are Not Enough: What True Recovery Looks Like in 2026

Backups are a critical part of business resilience, but they are not the same as recovery. In 2026, small businesses and government contractors need validated backups, tested recovery procedures, clear response plans, and secure restoration processes to keep operations moving when ransomware, outages, or system failures occur.

Downtime Is a Cybersecurity Problem, Not Just an IT Problem

Downtime can affect payroll, customer service, compliance, productivity, revenue, and reputation. For small businesses and government contractors, outages are no longer just technical issues. This blog explains why downtime should be treated as a cybersecurity and business resilience problem, and how organizations can better prepare for disruptions.

Zero Trust Without the Buzzwords: What It Actually Looks Like in Practice

Zero Trust is often discussed as a complex cybersecurity strategy, but at its core, it is about verifying access, limiting unnecessary permissions, and reducing risk. This blog explains what Zero Trust actually looks like in practice for small businesses and government contractors — without the buzzwords, hype, or confusion.

Access Creep Is a Business Risk: How Over-Permissioned Users Create Exposure

Access creep happens when users accumulate permissions over time and keep access they no longer need. For small businesses and government contractors, this creates unnecessary cybersecurity, compliance, and operational risk. This blog explains how over-permissioned users increase exposure and what organizations can do to strengthen access controls, reduce privilege misuse, and improve audit readiness.

Why Identity-Based Attacks Dominate Cybersecurity in 2026

Identity has become the new cybersecurity perimeter. In 2026, attackers are increasingly using stolen credentials, MFA fatigue tactics, and identity misuse to gain access to business systems. This blog explains why identity-based attacks are dominating the threat landscape and what small businesses and government contractors can do to strengthen access controls, improve MFA, and reduce exposure.
