CMMC 2.0 and Defense Supply Chain Attacks: Practical Steps to Build Resilience Across Your Vendor Ecosystem

Supply chain attacks keep rising because attackers go where trust and access already exist—third-party vendors, managed service providers, and software suppliers. If you handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), your security posture is only as strong as your partners’. CMMC 2.0 responds to this reality by placing verifiable expectations on every tier that touches sensitive DoD data. In this post, we’ll break down the threat, connect it to CMMC’s objectives, and share a practical roadmap you can start using today—grounded in inclusive, plain language and real-world scenarios.

Why the Defense Supply Chain Is a Prime Target

  • The attack surface is huge. Organizations share data with hundreds of vendors, yet few have mature processes to evaluate and improve vendor cybersecurity posture. In 2023, 15% of breaches involved a defense supply chain compromise, and 98% of companies had at least one vendor that experienced a breach. This is a perfect storm of exposure and limited oversight.
  • High-profile cases illustrate the risk. The SolarWinds Orion compromise showed how malicious code in a trusted update can ripple across government and commercial networks. Likewise, the 2023 third-party breach linked to Infosys McCamish Systems affected more than 57,000 Bank of America-related entities, underscoring how downstream vendors can become a gateway for attackers.

Inclusive takeaway: regardless of your organization’s size, role, or location within the Defense Industrial Base (DIB), defense supply chain risk touches everyone who processes, stores, or transmits FCI/CUI.

Vendor Management Systems vs. GRC Tools: Key Differences Explained

Key differences between GRC tools, and vendor management systems in terms of scope, integration, core functionality and outcomes.

Vendor Management Systems vs. GRC Tools: Understanding the Key Differences and How They Can Benefit Your Organization


In today’s fast-paced business environment, managing risk and ensuring compliance are critical. As organizations increasingly rely on third-party vendors, it’s more important than ever to have the right tools to assess and monitor vendor risk, alongside maintaining overall governance and compliance. But here’s the catch: while the terms GRC tools and Vendor Management Systems (VMS) are often used interchangeably, they serve very different purposes.

So, why does this matter?

If your organization is looking to streamline vendor management or strengthen your risk and compliance processes, it’s crucial to understand when to use GRC tools and when to turn to a Vendor Management System (VMS). Both can help manage risk, but they do so in distinct ways.

GRC platforms govern risk across the entire organization, while Vendor Management System tools specialize in managing the lifecycle of third‑party vendors.

In this article, we’ll explore the key differences and discuss how to make the right choice for your business, or organization.
