Since Anthropic introduced Claude Code Security in February 2026, application security has moved from pattern-matching to reasoning. This is not another SAST scanner bolted onto the pipeline. It is AI-native code security: a frontier model that reads your codebase the way a forty-year security diagnostician would, follows data from source to sink, reasons about how components trust each other, and surfaces the authorization, business-logic and supply-chain flaws that signature-based tooling has missed for decades.
Security Institute has run it in production since launch. We bring four decades of security operations experience to make it a standing, secure-by-design control inside your SDLC, not a quarterly report.
Legacy SAST and DAST tools match code against known vulnerability signatures and bury teams in false positives. Claude Code Security does reasoning-based vulnerability discovery: it follows untrusted input from source to sink, models the trust boundaries between services, and identifies exploitable weaknesses that signature matching cannot represent. At launch, Anthropic’s frontier models found more than 500 previously unknown bugs in production open-source software that had survived years of expert human review.
Reads your codebase the way a human security researcher would: how data moves through the application, where the trust boundaries sit between components, and where the exploitable attack surface actually lives.
Finds broken access control, insecure direct object references, business-logic abuse, injection paths and multi-service interaction bugs that rule-based tools cannot model. These are the weaknesses that appear in breach reports, not just in CVSS scores.
Proposes specific, reviewable patches with the reasoning behind each one, so remediation is measured in hours, not sprints. It augments your security team rather than replacing it. A human approves every change.
Runs where code is written and reviewed: the IDE, the terminal, the pull request and the CI/CD pipeline. Security becomes a continuous property of your software supply chain, not a separate gate after the fact.
This is the next step as a company committed to powering the defense of cybersecurity. [Claude Code Security is] a force multiplier for security teams.

A reasoning-based security scanner built directly into a developer workflow tool could compress the need for dedicated third-party security products in ways that have no real historical precedent.

We’ve been saying for months that AI systems were going to make traditional rule-based code security obsolete. This announcement confirms that.

“I’ve spent forty years diagnosing what breaks in production — at the Pentagon on September 11th, across six CENTCOM deployments in Iraq and Afghanistan, on trading floors, and inside 75 Fortune 100 networks. I’ve certified over 4,000 security professionals and trained more than 50,000 across 27 countries. I hold two US patents in data travel security. And I have used Claude Code every day since 2025 as a Max subscriber to build, secure and ship production systems.
When Anthropic announced Claude Code Security in February 2026, I recognized it immediately — this is the diagnostic capability I’ve spent my entire career trying to build manually. It doesn’t just scan for known patterns. It reasons about code the way I reason about network traffic: tracing how data moves, understanding where components interact, and finding the flaws that rule-based tools have always missed.
The organizations that deploy this capability first will have a structural advantage in application security. The ones that wait will be playing catch-up against adversaries who won’t.”

The model is powerful. Turning it into an operational control means decisions about scope, guardrails, triage, remediation SLAs and evidence for auditors: the same diagnostic judgment that has always separated competent security operations from exceptional ones.
Baseline your application security posture, then run Claude Code Security across your repositories and services. First validated findings within days, not quarters, triaged by exploitability and business impact, not CVSS scores alone.
Get StartedClaude Code Security wired into your CI/CD pipeline, pull-request workflow and security operations, with least-privilege agent permissions and audit trails from day one. Designed for your environment — cloud, on-premises, or hybrid. The same integration discipline applied at the Pentagon and Fortune 100.
Get StartedYour security and platform engineers trained to operate Claude Code Security: scoping runs, validating findings, driving remediation and reporting risk reduction to leadership. Drawing on the same mentoring methodology used to certify 4,000+ professionals through our CNA and Certified Enterprise programs.
Get StartedContinuous advisory as the capability evolves: new model generations, new vulnerability classes, and the secure-by-design expectations now written into CISA guidance, NIST SSDF and the EU Cyber Resilience Act. It also covers the security of your own AI agents and LLM applications — prompt injection, tool permissions, model and context supply chain. Not a one-time engagement — a sustained operational partnership.
