4Keyless is the security gateway between your AI agents and corporate systems. Enforce access policies, inject auth transparently, and audit every action — without exposing a single secret.

Built for zero-trust environments where AI automation meets regulatory compliance.
Secrets live in HashiCorp Vault, encrypted at rest with AES-256-GCM. AI agents never see plaintext credentials — not even in transit.
Define ALLOW and BLOCK on every plan. ASK (human-in-the-loop approval from the admin panel) unlocks on Growth and above.
Every proxy decision generates a cryptographically signed log entry. Filter by agent, system, decision type, or date. Built for SOC2 and compliance reviews.
Write JavaScript actions to transform request/response traffic (Starter plan and above). Handles SSO redirects, TOTP injection, legacy form logins — all running in an isolated sandbox.
Full tenant isolation at the database level. Role-based access with viewer, operator and admin — plus MFA for all users.
ASK-mode requests raise an approval notification for the designated operator right in the admin panel. Approve or deny access in seconds.
Install pre-configured SaaS integrations, auth scripts, actions, and policies in a single click. Map required credentials to slots and receive clean version updates.
Route outbound request traffic per Target System through SOCKS5, HTTP, or HTTPS exit proxies. Rotate IPs, bypass geo-restrictions, and evade rate limits easily.
Natively speak the Model Context Protocol. Expose all your tools aggregate-style at a single endpoint (mcp.4keyless.io/mcp) for Cursor and Claude Desktop with per-tool policies.
4Keyless sits between your AI agents and your systems. No code changes required on either side.
Select pre-configured integrations from the Blueprint Marketplace to provision systems, scripts, and default access policies in a single click.
Bind required credential slots safely to HashiCorp Vault. Adjust access rules to ALLOW, BLOCK, or ASK mode to control agent execution.
Point your agent's HTTP proxy or MCP client to the managed gateway. Access is evaluated, authenticated, and logged in under 100ms.
Meet SOC2, ISO 27001, and LGPD requirements. Every AI access is logged, signed, and auditable. Block sensitive systems by default, allow-list only what's needed.
Onboard AI automation agents to internal tools without sharing credentials. Centralize governance in one admin panel instead of distributing secrets across teams.
Give agents standardized access to corporate APIs and legacy SaaS. Script Actions handle complex auth flows (OAuth, TOTP, form login) without modifying target systems.
Let agents reach courts and government portals — PJe, e-SAJ, Gov.br and more — with ICP-Brasil, eIDAS and PIV/CAC certificates injected at the proxy. The private key never leaves the vault.
Every design decision in 4Keyless follows Zero Trust principles. AI agents are untrusted clients. Access is never assumed — it's verified at every layer.
The same credentials, policies and audit trail govern both your automations and the people on your team — no secret ever leaves the vault.
Point any agent's HTTP proxy or MCP client at the 4Keyless gateway. Credentials are injected on the fly, policies are enforced per request, and every call is logged — the model never sees a secret.
Give people on your team the same governed access through the 4Keyless Chrome extension. They sign in to protected systems without ever seeing or copying the credential — under the same policies and the same audit trail.
