Your AI tool generates thousands of lines of code daily, yet the majority of them often go without thorough examination. CybeDefend operates seamlessly within the agent as it develops code. With a single command, VibeDefend is integrated into platforms such as Claude Code, Cursor, Windsurf, GitHub Copilot, Codex, and other coding agents. From that moment on, the agent incorporates your business guidelines, automatically sourced from your repository (including tenant scoping, soft delete, and audit on write), alongside your established security protocols (like OWASP, SOC 2, GDPR, and ISO 27001). It continuously scans each code change while the file remains open, implementing safeguards that prevent the execution of harmful commands like rm -rf, sudo, or unauthorized access to your sensitive information before they can be executed. Supporting this functionality is a comprehensive Application Security platform that encompasses SAST, SCA, secrets management, Infrastructure as Code (IaC), CI/CD, container scanning, and an AutoFix feature.

Every app, build pipeline and AI agent that calls Stripe, OpenAI or any other third-party API needs that API key. So copies of live keys pile up in .env files, CI settings, laptops and agent environments, and each copy is one more place a key can leak from: a poisoned package, a prompt-injected agent, a compromised build or a config file pushed by mistake. A stolen key keeps working until someone notices, then has to be replaced everywhere it was copied. KnoxCall keeps the real key in one place and adds it to each call on its way out. Your apps, pipelines and agents hold only a KnoxCall token. If a token leaks, one click revokes it everywhere, without rotating the provider key. Every call is logged with the name of the app or agent that made it. Because every call already passes through KnoxCall, it's also the natural place to put guardrails on AI agents. Each agent can be given its own spending limit, every prompt is checked before it reaches the model, and the personal data KnoxCall detects is swapped out before the model sees it, then put back in the reply. Security teams stay in control of the foundations. CI jobs can authenticate with workload identity instead of a stored secret, and on the Enterprise plan you can lock your keys with a master key held in your own cloud account and manage access through your existing single sign-on and SCIM provisioning. KnoxCall fits the stack you already use, with SDKs for Node, Python, Go, PHP, Ruby, React and the browser. Start on the free plan with no card required, or move to a paid plan from $19 a month.
