How Cyber AB Marketplace Supports C3PAO and CMMC Provisional Assessor

As cybersecurity requirements continue to evolve for Department of Defense (DoD) contractors, staying compliant with frameworks like the Cybersecurity Maturity Model Certification (CMMC) is essential. A critical piece of this compliance journey involves understanding how the Cyber AB Marketplace supports both C3PAO organizations and the role of the CMMC Provisional Assessor. For organizations like Ariento, which offer compliance and assessment services, aligning with the Cyber AB Marketplace is a crucial part of maintaining credibility and visibility.

What Is the Cyber AB Marketplace?

The Cyber AB Marketplace is the official directory for all authorized participants in the CMMC ecosystem. It is managed by the Cybersecurity Accreditation Body (Cyber AB), formerly known as CMMC-AB. The marketplace includes listings for authorized C3PAO firms, registered practitioners, and certified professionals who help guide contractors through CMMC compliance.

This centralized platform promotes transparency, provides easy access to verified professionals, and ensures that only approved organizations and individuals can support defense contractors in the certification process.

Support for C3PAOs

A C3PAO (Certified Third-Party Assessment Organization) is responsible for conducting formal CMMC assessments. Being listed in the Cyber AB Marketplace verifies that a C3PAO meets all required criteria, such as maintaining a mature cybersecurity posture and employing trained assessors.

For assessment providers like Ariento, being recognized in the marketplace is vital. It affirms credibility, makes services more accessible to contractors, and ensures clients that the assessment process will be in line with current CMMC requirements. Importantly, marketplace listing also ensures the C3PAO has completed the FedRAMP Moderate Baseline assessment or employs solutions like FedRAMP EDR for enhanced security, further validating their readiness.

Role of the CMMC Provisional Assessor

The CMMC Provisional Assessor plays a vital role during the early stages of CMMC rollout. These assessors were part of the initial cohort trained to evaluate contractors ahead of the full implementation of CMMC. Their listings on the Cyber AB Marketplace not only confirm their credentials but also ensure that contractors can confidently connect with professionals who have foundational experience in the model.

With the guidance of a CMMC Provisional Assessor, contractors can better understand what assessors will be looking for during evaluations and how to prepare accordingly. Many of these assessors also work with C3PAO organizations or CMMC consulting firms such as Ariento, offering practical insights based on first-hand experience.

The Role of FedRAMP EDR

The use of FedRAMP EDR (Endpoint Detection and Response) solutions is another critical area of alignment. These tools help C3PAO organizations and their clients maintain strong security controls, which are essential during CMMC assessments. A listing on the Cyber AB Marketplace signals that a company not only meets CMMC standards but also utilizes compliant technologies like FedRAMP EDR to enhance cyber resilience.

Final Thoughts

The Cyber AB Marketplace is more than a directory — it's a trusted hub that supports the integrity and transparency of the CMMC ecosystem. For C3PAO organizations and CMMC Provisional Assessors, being listed helps build trust and ensures alignment with DoD expectations. And for defense contractors, working with listed professionals like those at Ariento is the first step toward confident, secure, and successful CMMC compliance.

Tips for Finding the Best Deals in a Cyber AB Marketplace

Navigating compliance and cybersecurity services can be challenging for businesses in the defense contracting space. With the introduction of the Cybersecurity Maturity Model Certification (CMMC), the Cyber AB Marketplace has become a critical hub for connecting organizations with authorized service providers. Whether you're searching for help with your System Security Plan, assessment support, or advisory services, knowing how to find the best value is essential.

At Ariento, a trusted name in cybersecurity and compliance, we understand what it takes to stand out in the crowded Cyber AB Marketplace. Here are some helpful tips for finding the best deals without compromising on quality or security.

Look for Verified Providers

The Cyber AB Marketplace (formerly the CMMC-AB Marketplace) is your go-to source for vetted providers. Start by filtering your search to include only organizations listed as Registered Provider Organizations (RPOs), Certified Third-Party Assessor Organizations (C3PAOs), or those affiliated with CMMC AB standards. These designations indicate that the provider meets high levels of trust, training, and compliance with industry requirements.

Ariento is a registered and experienced provider in the Cyber AB Marketplace, with a proven track record of delivering reliable, cost-effective cybersecurity and compliance services.

Evaluate the Full Scope of Services

When comparing providers, don’t just look at price. Consider the value of the entire service package — does it include a detailed gap analysis, help with drafting your System Security Plan, and support for continuous monitoring?

A good deal includes more than just a quick fix. For example, Ariento provides end-to-end services, from helping you build your System Security Plan to preparing your environment for formal assessment and long-term compliance.

Ask for Bundled Packages

Bundled services can offer significant cost savings. Many providers in the Cyber AB Marketplace offer discounts when multiple services — such as readiness assessments, documentation support, and managed cybersecurity — are packaged together.

At Ariento, we offer flexible, bundled solutions tailored to the size and needs of your organization. This approach not only helps reduce cost but also ensures a smoother compliance experience.

Read Client Reviews and Case Studies

Before selecting a provider, review testimonials and case studies from similar businesses. Real-world results matter. Look for success stories where companies achieved compliance efficiently, particularly in areas like developing a System Security Plan or aligning with CMMC AB guidance.
