On February 19, 2026, Anthropic announced Claude Code Security — and the application security landscape shifted permanently. This is not another static analysis tool. It reads and reasons about code the way a forty-year security diagnostician would: tracing data flow, understanding component interactions, and finding the complex vulnerabilities that pattern-matching tools have missed for decades.
Security Institute is among the first practices deploying it. We bring four decades of production security expertise to help enterprises implement this capability at pace.
Traditional static analysis tools match code against known vulnerability patterns. They catch the basics. Claude Code Security traces data flow end to end, understands component interactions, and identifies the complex vulnerabilities that pattern-matching has missed for decades. Anthropic’s Opus model found over 500 bugs in production open-source software that survived years of expert human review.
Reads your codebase the way a human security researcher would. Traces how data moves through your application, how components interact, and where the attack surface actually lives.
Identifies broken access control, business logic flaws, and multi-component interaction bugs that rule-based tools cannot detect. These are the vulnerabilities that cause breaches.
Suggests specific patches for human review. Augments your security team rather than replacing it. The expert stays in the loop.
Built directly into the development environment. Security scanning happens where the code is written, not in a separate tool 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 for the past year, I’ve used Claude Code daily as a Max subscriber to build and ship production systems.
When Anthropic announced Claude Code Security on February 19th, 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 tool is powerful. But deploying it effectively in an enterprise environment requires the same kind of diagnostic judgment that has always separated competent security operations from exceptional ones.
Evaluate your existing application security posture and deploy Claude Code Security against your codebase. First findings within days, not quarters. Prioritized by actual risk, not CVSS scores alone.
Get StartedClaude Code Security integrated into your CI/CD pipeline, developer workflow, and security operations. Designed for your environment — cloud, on-premises, or hybrid. The same integration discipline applied at the Pentagon and Fortune 100.
Get StartedYour security team trained on Claude Code Security operations, interpretation, and remediation. 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 vulnerability classes detected. Remediation strategies refined. Security posture measured and reported. Not a one-time engagement — a sustained operational partnership.
Get Started$15B+ in cybersecurity stocks dropped after the announcement. We think every one of these companies should go up. AI doesn’t replace complex security platforms — it makes them spectacularly more effective.
