Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

In August 2023, while thousands of students at William Jewell College were hauling mini-fridges and textbooks into dorms, the invisible, digital heart of the campus was flatlining. There was no internet. No email. Even the HVAC system, tied to a compromised network, had shut down in the sweltering Missouri heat. The culprit? LockBit, a prolific ransomware syndicate that just hit Boeing days prior.

HR teams manage every stage of the employee lifecycle, from hiring and onboarding to performance management and offboarding. Security teams manage data access, behavioral monitoring, and incident response. Insider risk lives at the intersection of both. When HR and security operate independently, the gaps between them are exactly where data loss happens, and the moments of highest exposure are almost always HR events, such as a resignation submitted, a role change processed, a termination decision made.

Modern software is not written from scratch. It’s assembled. Developers pull from open-source repositories, import third-party libraries, accelerate development with AI coding assistants, and deploy across multi-stage CI/CD pipelines that span dozens of tools, services, and vendors.

For the record, I always thought the GRC was cool. NIST Framework? Yes please. Vendor risk register? Tell me more! Not everyone shared my enthusiasm for effective and efficient cyber risk reduction. Until now. Suddenly, seemingly overnight, managing the digital supply chain became really, really important. AI governance (a phrase that didn’t even exist a year ago) is now the topic of boardroom discussions. Yes, it will look different and operate in a new way.

Most guidance published on AI agent security is written for enterprise organizations. It assumes dedicated AI security functions, red teams, platform engineering groups, and the budget to commission purpose-built tooling. If your security team is three people covering five hundred employees and a cloud environment that grows faster than you can document it, that guidance was not written for you. The five posts in this series have established the threat landscape.

Don't wait for KEV listing Waiting for CISA KEV may be too late. Across six months of Nucleus research, public PoCs gave defenders a median 5.5 days of runway before KEV listing, every single time.

Your security team has hardened your perimeter. You have MFA enforced, endpoint detection running, and your crown-jewel systems are locked down tight. Then a vendor you onboarded two years ago, a mid-size SaaS tool your procurement team signed off on, gets breached. They had access to your customer data. Now it is your problem. This is the third-party risk problem in one paragraph. And it is why TPRM has moved from a compliance checkbox to a board-level conversation.

Technology is essential, but technology alone does not create resilience. Resilience comes from informed decisions, clear priorities, and leadership alignment.
