Credential-injecting forward proxies for AI agents

Stop baking API keys
into your agents.

CIFP injects real credentials at the wire level — your agent never sees the secret at all. Store keys in encrypted vaults, send requests with {$TOKEN} placeholders, and let your own dedicated proxy handle the rest.

Built for developers shipping AI agents into production. No SDK required — works with any HTTP client, any language, any AI framework. Quantum-safe cryptography comes standard.

Built for the adversary who is recording right now

“Harvest now, decrypt later” attacks stockpile encrypted traffic today for tomorrow's quantum computers. CIFP's cryptography makes that strategy worthless — on every layer, by default, with no configuration.

At rest: already post-quantum

Every secret lives in an AES-256-GCM encrypted vault on your dedicated machine, wrapped by a KMS-managed key. Even a quantum computer only halves AES-256's strength — a stolen snapshot stays unreadable. One-click key rotation included.

In transit: hybrid PQ key exchange

Share links and machine APIs negotiate hybrid post-quantum TLS (classical X25519 + NIST-standardized ML-KEM-768) by default. An attacker must break both the classical curve and the lattice to recover a session.

Signed with lattice cryptography

The private DNS resolver's access tokens can be signed with ML-DSA-65 — the NIST FIPS 204 post-quantum signature standard. Algorithm-agile and rotatable without downtime.

Encrypted vaults, scoped to hosts

Store secrets in per-proxy vaults bound to the exact hosts they belong to. Your OpenAI key can only ever be injected into api.openai.com — a compromised prompt can't exfiltrate it to an attacker's server. Values are write-only: the API never returns them.

  • Service templates for OpenAI, Anthropic, GitHub, Stripe & Linear
  • Per-port credential scoping across 20k+ ports per proxy
  • One-click KMS-backed key rotation (no downtime)

Share access, not secrets

Hand a teammate a secure share link instead of pasting the key in Slack. Shares are TLS-terminated endpoints on your proxy — expiring, use-limited, and revocable — so collaborators get working access while the real credential never leaves the vault.

  • Expiring, use-limited, one-click revocable links
  • Vault-scoped — shares can only reach the hosts you allow
  • Every use logged with full audit metadata

Two modes. Pick the one that fits.

Every CIFP proxy runs in one of two modes. Most people start with Auto-Auth. Reach for Firewall when you need full control over what your code is allowed to do.

Start here

Auto-Auth

Everyday use & quick integration

Add a {$SECRET_NAME} placeholder to any request header. CIFP replaces it with the real credential before the request leaves the proxy. No TLS interception. No CA cert. No code changes beyond switching your proxy URL.

  • curl commands, scripts, and Jupyter notebooks
  • Any HTTP client in any language
  • Keeping API keys out of source code & CI
  • Sharing credentials across a team without exposing them
If you're not sure which mode to pick — this is the one.
Advanced

Firewall

AI agents & automated workflows

Full TLS interception. CIFP decrypts every outbound HTTPS request, evaluates it against your CEL rule set, injects credentials automatically, and re-encrypts before forwarding. Your code sends requests normally — no placeholders needed.

  • AI agents making autonomous, unattended API calls
  • Blocking requests to unexpected domains or endpoints
  • Compliance — audit every request with full metadata
  • Human-in-the-loop approval before sensitive calls go out
Requires installing the proxy's CA cert on the client machine or container.

Everything your agent needs to stay secure

From simple credential injection to full MITM inspection and private DNS filtering — CIFP handles the entire security surface of your agent's outbound traffic.

Up and running in minutes

No infrastructure to manage, no SDK to install. CIFP is a standard HTTP proxy — it works with every language and framework that supports proxy environment variables.

01

Create a proxy

Pick a region, choose auto-auth or firewall mode, and click Create. Your dedicated VM is up in ~5 seconds.

02

Add your secrets

Paste API keys, tokens, and passwords into the secrets panel. They are encrypted with AES-256-GCM at rest immediately.

03

Point your agent at the proxy

Set http_proxy / https_proxy to your proxy URL. Use {$SECRET_NAME} as the placeholder wherever credentials belong.

04

CIFP handles the rest

Every outbound request has real credentials injected at the wire level. Your agent code stays clean, and your secrets stay safe.

Pro+ add-on

CIFP DNS — private DNS filtering

Route your proxy's DNS through our self-hosted resolver. Block ads, trackers, and malware at the DNS layer before requests are even made. Shannon-entropy detection catches DGA malware and DNS tunnelling automatically. Per-proxy custom blocklists, synced in real-time via short-lived JWTs with zero-downtime key rotation.

Straight answers

The questions every security-conscious team asks before routing traffic through a proxy.

Can CIFP read my API keys?

Secrets are encrypted with AES-256-GCM the moment you save them and are never returned over the API. They are decrypted only inside your dedicated proxy VM, at the instant a request is injected on the wire. Neither your agent code nor the dashboard ever sees plaintext again.

Do I need to install an SDK or change my code?

No. CIFP is a standard HTTP forward proxy. Set http_proxy / https_proxy, swap credentials for {$SECRET_NAME} placeholders, and every HTTP client in every language keeps working unchanged.

Auto-Auth or Firewall — which mode should I pick?

Start with Auto-Auth: it covers scripts, notebooks, and everyday integrations with zero setup beyond a proxy URL. Reach for Firewall when an AI agent makes unattended calls and you want every request evaluated against CEL rules — with human approval for sensitive ones.

What happens after the $5 Test Drive?

You get 3 days of full access to the plan you choose — Pro or Pro+ — with unlimited bandwidth under the Fair Use Policy. It then renews at that plan’s selected monthly or annual rate unless you cancel first. Each subscription and its dedicated proxy can be managed independently.

When is CIFP overkill?

Honestly? If you have one script calling one API, an environment variable is fine. CIFP pays off when you run multiple agents or services, share credentials across a team without exposing them, or need an audit trail of every outbound request.

How is CIFP quantum-safe?

Secrets at rest use AES-256-GCM — symmetric encryption that quantum computers can only weaken to a still-infeasible ~128-bit strength. Share links and machine APIs negotiate hybrid post-quantum TLS (X25519 + NIST-standardized ML-KEM-768) by default, and the private DNS resolver can sign tokens with ML-DSA-65 (FIPS 204). Traffic recorded today stays unreadable — even to a future quantum adversary.

Can I share credentials with teammates without exposing them?

Yes — that is what secure shares are for. Generate an expiring, use-limited, TLS-terminated share link scoped to specific hosts. Teammates route through it and get working access; the real credential never leaves your encrypted vault, and every use is logged. Revoke anytime with one click.
