Semgrep Guardian

The vulnerabilities, malicious packages, and hardcoded secrets your agent introduces, detected and resolved before a PR is ever opened.

Install Today

What's included in The Semgrep Guardian?

The Semgrep Guardian installs directly into any AI coding agent. It bundles three components; an MCP server, hooks, and skills. We ensure every line of AI-generated code is scanned against your org's policies before it ever reaches a pull request. No more delaying PR's due to vulnerabilities generated by AI.

MCP Server

The agent asks Semgrep and Semgrep answers. The MCP server exposes Semgrep's scanning capabilities as tools the agent can call directly.

Learn more about the MCP

Hooks

Consistent scanning that your team can rely on. Hooks fire on every file write, ensuring a scan regardless of what the agent does.

Skills

The agent knows how to fix security vulnerabilites, not just find them. Skills are bundled instructions that teach the agent how to respond to a finding, not just surface it, but walk through the remediation.

Use Semgrep Skills

You set the rules. The Semgrep Guardian enforces them.

AppSec teams can block malicious and hallucinated dependencies before they ever install, stop hardcoded API keys and cloud credentials from reaching version control, and enforce org-specific coding patterns across every agent in the organization. These are the guardrails security teams have always wanted but could never enforce at scale until now.

With The Semgrep Guardian, the policies you have defined in your head for years become rules that fire automatically the moment an agent writes code. Every OWASP violation, every leaked secret, every suspicious package gets caught and fixed before it reaches a pull request, without a ticket, without a backlog, and without asking developers to change how they work.

Claude Code

The Semgrep Guardian is your organization's dedicated Claude Code security reviewer.

The Semgrep Guardian brings your org's existing rules, policies, and context directly into Claude Code, so every file an agent writes is scanned against the standards your security team has already defined.

Windsurf

The Semgrep Guardian is your organization's security layer for Windsurf.

The Semgrep Guardian brings your org's existing rules, policies, and context directly into Windsurf, so every file an agent writes is scanned against the standards your security team has already defined.

Cursor

The Semgrep Guardian is the security layer Cursor was missing.

The Semgrep Guardian brings your org's existing rules, policies, and context directly into Cursor — every file an agent writes, scanned against the standards your security team has already defined.

Semgrep Guardian + Cursor

Supply Chain & Malicious Dependencies

Block hallucinated packages before they install (the tenorflow → tensorflow moment)
Flag known malicious packages from the Semgrep supply chain database
Enforce approved package lists — only use dependencies your org has vetted
Detect typosquatting attempts in agent-suggested dependencies

Code Quality & Security Patterns

Enforce OWASP Top 10 guardrails on AI-generated code
Block known vulnerable patterns like SQL injection, XSS, and IDOR — at generation time
Enforce org-specific patterns — "all new APIs must use v2 framework," "auth always checked before DB access"

Secrets & Credentials

Prevent hardcoded API keys, tokens, and passwords from ever reaching version control
Enforce secrets management standards — credentials must come from vault, not literals
Catch cloud provider credentials (AWS, GCP, Azure) before they leak

Compliance & Governance

Ensure generated code meets regulatory standards (SOC2, HIPAA, PCI)
Full audit trail of what agents generated, what was flagged, what was fixed
Policy-as-code — version control your security rules the same way you version your code

Secure your AI generated code in less than 5 minutes.
