Find
Find the vulnerabilities that actually get exploited
Gecko reads your code, infrastructure and design docs as one system, and finds the logic flaws that live between them.

Your Codebase
Gecko reasons across your code, infrastructure and intent to find the vulnerabilities that actually get exploited, prioritize them from the attacker’s perspective, fix the root cause and every variant in one PR, and make sure they never come back.

“The vulnerabilities that keep CISOs up at night are business logic flaws and multi-step attack chains most tools can’t see. That’s where breaches happen. Gecko is built to find them.”
Jon Raper
CISO, Chevron
“One tool that gives us great results from a full scanning perspective, and every single pull request that goes in, we know is protected.”
Keith Williams
Head of Engineering, Cal.com
“Gecko found business logic vulnerabilities we’ve only ever been able to get from manual code reviews, and the false positive rate is the lowest we’ve seen from any scanner”

Find What’s Exploitable
Fix what caused it
100 alerts, one cause. Gecko fixes the decision upstream,
so you can say goodbye for good.
Prioritize
Prioritize from the attacker’s perspective, not a flat list
Attackers chain small bugs into big breaches. Gecko ranks your findings by the attack path they form, so the lows that add up to a takeover outrank a critical nobody can reach.
Fix
Fix the root cause and every variant in one PR
One PR fixes the design decision behind a finding, and every variant it created, in your codebase’s style.
Prevent
Never see the same vulnerability twice
Every fix becomes a guardrail, enforced on every PR and inside the AI agents writing your code.
Recurrence, Not Just Response
MTTR tells you how fast you closed a ticket. It doesn’t tell you the flaw stayed gone. Gecko fixes vulnerability classes at the root, so the number that keeps falling is the one that measures real progress.
Integrations
Findings and Fixes Where You Already Work
Gecko connects to your repos, pipelines, and trackers with native connectors for Claude, Codex, and any MCP server.
