Security teams have long relied on static analysis tools to catch vulnerabilities before code ships. Those tools are useful, but they have a fundamental limitation: they match code against known patterns. They don’t understand your application.
AWS is taking a different approach with its latest addition to AWS Security Agent. The company recently released full repository code review in preview — a feature that goes well beyond traditional scanning by reasoning about your entire codebase the way a security researcher would.
What’s New
Full repository code review is a new capability in AWS Security Agent that performs deep, context-aware security analysis of an entire codebase. It’s now available in preview at no additional charge for existing AWS Security Agent customers.
Unlike traditional static analysis tools that match code against known vulnerability patterns, full repository code review reasons about an application’s architecture, trust boundaries, and data flows to surface systemic vulnerabilities that pattern-matching tools miss.
That’s a meaningful distinction. Most SAST tools will flag a SQL injection or an exposed credential if it fits a recognized pattern. What they won’t do is trace how data moves across services, how trust boundaries are defined, or how one seemingly minor flaw could chain into a larger exploit. This new feature is designed to catch exactly that.
When vulnerabilities are found, the scanner produces developer-ready findings with transparent evidence and concrete remediation — specific fixes tied to the exact file and line, so teams can identify and address security issues faster.
The Broader Context
A full repository code review is part of a broader set of capabilities that AWS has been building into its Security Agent. The agent is designed to continuously validate application security from design to deployment, covering automated application security reviews and on-demand penetration testing.
The penetration testing feature reached general availability on March 31, 2026, making it the first of the three capabilities — design review, code review, and penetration testing — to move beyond preview. Design review and full repository code review remain in preview.
AWS Security Agent is context-aware — it understands your application design, your code, and your specific security requirements. It continuously scans for security violations and runs penetration tests on demand, instantly and without scheduling.
Under the hood, the agent runs a specialized multi-agent pipeline — a coordinated swarm of purpose-built agents, each responsible for one phase of the testing workflow. For code review specifically, that means analyzing architecture, tracking data flows, and building a picture of how the application actually behaves — not just what it looks like on the surface.
What This Means for DevOps Teams
For development teams, the most practical implication is speed and specificity. Traditional security review cycles often create friction — findings come back late, lack context, or require a security specialist to interpret. Fixes tied to specific files and lines change that dynamic.
The key differentiator is that the agent ingests source code, architecture diagrams, and documentation to understand how the application was designed before it tries to identify problems. This enables it to identify how individual vulnerabilities connect into higher-severity attack chains — the kind of chained exploits traditional scanners are architecturally blind to.
For DevSecOps practitioners trying to shift security left, that’s a significant step. Security findings that arrive with context and ready-to-implement fixes are far more likely to get addressed quickly — and correctly.
“AWS Security Agent’s full repository review shows AppSec moving from pattern-matching to architectural reasoning. That has gravity. By tracing trust boundaries, data flows, and chained exploits across the codebase, AWS positions the cloud platform itself as where security reasoning happens.”
“That reshapes procurement logic for security teams and competitive ground for scanners. Buyers will weigh whether platform-native reasoning, bundled at no extra charge, displaces tools they already license. Vendors that only match patterns will struggle to justify their place in the pipeline,” said Mitch Ashley, VP and Practice Lead, Software Lifecycle Engineering, The Futurum Group.
Available Now in Preview
AWS is prioritizing free early access for customers, giving defenders the opportunity to strengthen their codebases and share what they learn so the whole industry can benefit. AWS is also actively soliciting feedback via the built-in mechanism in the Security Agent web application or by contacting account teams.
For organizations already using AWS Security Agent, enabling full repository code review is accessible directly through the Security Agent console.
It’s still early, and preview status means the experience will continue to evolve. But the direction is clear: AI-assisted security that understands your application architecture, not just your code patterns, is becoming a practical option for development teams — not just a research concept.
