The Problem

AI agents need access.
You can't trust them with secrets.

  • ✕ Giving raw credentials to agents leaks secrets into prompts and logs
  • ✕ No governance over which agent accesses which system
  • ✕ Zero audit trail for compliance or incident response
  • ✕ Custom auth flows (SSO, TOTP, form logins) are impossible to automate safely
The Solution

4Keyless acts as the secure
intermediary — always.

  • ✓ Credentials stay in Vault — agents receive zero plaintext secrets
  • ✓ Fine-grained ALLOW/BLOCK/ASK policies per agent × system
  • ✓ Every request produces a signed, immutable audit log entry
  • ✓ Script Actions adapt complex auth flows without touching legacy systems
Platform capabilities

Everything security teams need
to govern AI access

Built for zero-trust environments where AI automation meets regulatory compliance.

Credential Isolation

Secrets live in HashiCorp Vault or KMS, encrypted at rest with AES-256-GCM. AI agents never see plaintext credentials — not even in transit.

Access Policies

Define ALLOW, BLOCK, or ASK rules for every agent-to-system pair. Human-in-the-loop approval via mobile or Telegram for sensitive operations.

Immutable Audit Logs

Every proxy decision generates a cryptographically signed log entry. Filter by agent, system, decision type, or date. Built for SOC2 and compliance reviews.

Script Actions

Write JavaScript actions to transform request/response traffic. Handles SSO redirects, TOTP injection, legacy form logins — all sandboxed in V8 isolates.

Multi-Tenant RBAC

Full tenant isolation at the database level. Role-based access with viewer, operator, admin and super_admin — plus MFA for all users.

Real-time Notifications

ASK-mode requests alert operators via Telegram Bot or mobile push (FCM/APNs). Approve or deny access in seconds, directly from your phone.

Marketplace Blueprints

Install pre-configured SaaS integrations, auth scripts, actions, and policies in a single click. Map required credentials to slots and receive clean version updates.

Exit Proxies (IP Rotation)

Route outbound request traffic per Target System through SOCKS5, HTTP, or HTTPS exit proxies. Rotate IPs, bypass geo-restrictions, and evade rate limits easily.

MCP Unified Gateway

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.

Simple by design

Up and running in minutes

4Keyless sits between your AI agents and your systems. No code changes required on either side.

Use cases

Built for teams operating
AI at enterprise scale

🏦

Fintech & Regulated Industries

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.

Compliance Audit trail
⚙️

DevOps & Platform Teams

Onboard AI automation agents to internal tools without sharing credentials. Centralize governance in one admin panel instead of distributing secrets across teams.

Centralized control Fast onboarding
🔬

AI Engineering 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.

Security architecture

Zero Trust,
all the way down

Every design decision in 4Keyless follows Zero Trust principles. AI agents are untrusted clients. Access is never assumed — it's verified at every layer.

AES-256-GCM at rest, TLS 1.3 in transit
mTLS between all internal services. Secrets only decrypted inside the proxy memory space.
Fail-closed by default
If approval timeout expires or any error occurs, access is denied. Never fail open.
Ed25519 signed audit logs
Every log entry is cryptographically signed. Tampering is detectable. Verifiable chain of custody.
V8 sandbox for Script Actions
Auth scripts run in isolated Deno V8 contexts. No filesystem, no network, no cross-tenant access.
🔒
SOC 2 Ready
Audit log + access control architecture aligns with SOC 2 Type II requirements
🌐
LGPD / GDPR
Data residency controls. Tenant isolation. No cross-tenant data access.
🏗️
On-premises
Deploy in your own VPC or data center. Air-gapped environments supported.
🔑
Vault Native
HashiCorp Vault integration out of the box. Bring your own KMS too.
