Everything you need to ship secure code

From static analysis to post-quantum attestation, Guardn covers the full security lifecycle.

300+ Security Rules

CWE Top 25, OWASP Top 10, secret detection, injection, cryptography, IaC, dependency analysis, and more. 255 rules include one-click auto-fix.

AI-Assisted Remediation

Built-in AI chat with five providers. Get fix suggestions, code rewrites, and explanations in context. Agent mode for autonomous security fixes.

Post-Quantum Attestation

Every scan is signed with ML-DSA-65 via CycleCore PQCaaS. Tamper-proof, quantum-resistant.

Full IDE Experience

File tree, multi-tab editor, terminal, AI chat, real-time findings panel. Everything in your browser.

Compliance Mapping

SOC 2, HIPAA, PCI DSS, NIST 800-53, OWASP ASVS, ISO 27001, CIS. Audit-ready from scan one.

Zero-Evidence Proofs

Prove code passed security checks without revealing source. Shareable, verifiable, PQ-signed.

Three steps to secure code

Browser, CLI, or CI. Paste, scan, fix in under 30 seconds.

Paste your code

Drop code into the browser IDE or connect a repo. Guardn supports any language.

Instant scan

300+ rules fire automatically. Findings appear in real time with severity and line context.

AI-assisted fix

Get fix suggestions, apply one-click remediation, and export PQ-attested results.

Use everywhere you write code

Browser IDE, CLI, GitHub Action, or pre-commit hook. Same 300+ rules, same PQ attestation.

CLI Scanner

Scan anywhere. No install needed with npx. JSON and SARIF output.

npx @guardn/cli scan .

or install: npm i -g @guardn/cli

GitHub Action

Scan every PR automatically. Findings as inline comments.

uses: guardn/action@v1

Pre-Commit Hook

Block insecure code before it reaches your repo.

guardn hooks install

Post-Quantum Cryptography

Scan results you can mathematically verify

Every scan is attested using ML-DSA-65 (FIPS 204), the NIST post-quantum digital signature standard. Results are tamper-evident and verifiable by any third party, even after quantum computers break classical signatures.
