About CybeDefend
CybeDefend offers VibeDefend, an AI code security tool that plugs into AI coding agents to keep business and security rules in front of the code the agents write. A single npx install command detects supported agents on the machine, then injects rules mined from your code along with references such as OWASP, SOC 2, GDPR and ISO 27001.
It scans agent diffs for issues such as SQL injection, secrets in source, vulnerable or compromised dependencies, public storage buckets and control-plane actions, and blocks risky operations like reading .env, deleting protected directories or running deletes without a WHERE clause. Findings appear before a pull request, and the agent can rewrite the line in the same session. The homepage does not state pricing, does not claim complete coverage, and notes that analytics and ad-measurement cookies from Google and Meta are used unless declined.
