Client Success Story
ISSO Support and DevSecOps for the CMS Marketplace
The CMS Marketplace runs FISMA High systems that must ship fast and pass a stack of federal audits. As a subcontractor to the prime, InterSec built DevSecOps into the Expedited Life Cycle and held continuous authority to operate with zero coverage disruptions.
The Challenge
CMS needed to launch updates rapidly while meeting strict compliance across multiple federal standards, and falling short on either speed or security would erode trust in the Marketplace. The difficulty came from three directions at once.
The Approach
Working as a subcontractor to the prime over roughly nine years, InterSec built DevSecOps checks into each step of the Expedited Life Cycle, so security moved at the same pace as delivery rather than gating it at the end. The approach rested on three practices.
The Solution in Practice
InterSec combined automated vulnerability scanning with secure coding practices and continuous penetration testing, letting CMS roll out updates with confidence rather than caution. Ongoing penetration testing and risk assessments caught emergent threats as systems changed, regular artifact updates kept the program audit-ready, and application security was built into development with secure coding standards, automated scans, and code reviews.
Speed and assurance were not a trade-off; DevSecOps built into the lifecycle let a high-tempo program ship fast and stay compliant at the same time.
Results & Impact
CMS held the balance between regulatory obligation and rapid feature delivery, reinforcing the Marketplace's reputation for reliable coverage.
Key Takeaways
Working With InterSec
High-tempo delivery and uncompromising compliance can coexist.
When security is built into the lifecycle, they reinforce each other. InterSec provides ISSO support and DevSecOps for federal programs that cannot afford to slow down or fall out of authorization. Let's talk about your environment.
