Why KnoxCall

Why KnoxCall?

STOP
hardcoding API credentials.

The problem

Traditional API security is broken

Developers face constant security nightmares managing API credentials across environments

Hardcoded Secrets

API keys buried in source code, accidentally committed to git, exposed in public repositories. One mistake = complete security breach.

.env File Chaos

Credentials scattered across hundreds of .env files in dev, staging, prod. When a developer leaves, you must rotate everything -- but which systems got updated? Which .env files still have old keys? It's impossible to track. Production breaks at 3am.

Rotation Nightmare

"Just rotate the API key" sounds simple until you realize it's in 47 different places. Rebuild apps, redeploy services, coordinate teams across time zones. Hours of downtime for what should be a 30-second change.

Access Sprawl

Credentials shared via Slack, email, sticky notes, password managers. No audit trail, no revocation, no idea who has access to what. Ex-employees still have production keys months later.

Compliance Chaos

SOC 2, GDPR, ISO 27001 audits become painful without proper credential management and change tracking.

Multi-Tenant Hell

Managing different credentials for each customer or environment? Complexity multiplies, security weakens.

Mobile Exposure

Mobile apps with embedded API keys are reverse-engineered in minutes. Your backend credentials are public.

The solution

KnoxCall: your security proxy layer

A zero-trust credential proxy that sits between your apps and external APIs

Centralized Vault

All credentials encrypted and stored in one secure location. Military-grade AES-256 encryption with automatic versioning and rollback.

Security

Instant Rotation

Update credentials once, everywhere. No redeployments, no downtime, no coordination headaches. Change propagates instantly.

Operations

Zero-Code Integration

Just change your API endpoint. KnoxCall handles authentication, injection, and proxying. Works with any HTTP API.

Developer

Complete Visibility

Every API call logged with full audit trail. Know who accessed what, when, and from where. Compliance made simple.

Compliance

Advanced Protection

Request signing, rate limiting, IP whitelisting, and DDoS protection built-in. Enterprise security without the enterprise complexity.

Security

Multi-Tenant Native

Isolated credential spaces per customer. Team management, role-based access, and perfect tenant separation.

Scale

Data Protection Suite

Five products. One platform.

KnoxCall ships the building blocks teams used to assemble from HashiCorp Vault, AWS KMS, Basis Theory, and Svix. Same primitives, one billing line, one audit log, one admin UI.

Vaults

Tokenize PCI cards, SSNs, emails, or any sensitive value. Format-preserving tokens pass Luhn checks (PAN), regex shape (SSN), and domain-routing (email) so existing systems keep working. Cryptographic erasure on demand.

Tokenization

Crypto Keys

Encryption-as-a-service. AES-256-GCM, HMAC-SHA256/512, RSA, ECDSA P-256/P-384, Ed25519. Sign JWTs (RS256, ES256, EdDSA). Export public keys. Your apps never see the key material.

KMS / Vault Transit

Inbound Webhooks

Point Stripe, GitHub, Slack at a KnoxCall URL. We verify the HMAC signature in any of six formats, enforce 5-minute replay windows, audit every event, and forward verified payloads to your app with X-Knox-Verified: true.

Receive

Webhook Signing

Sign outbound events in Stripe-, GitHub-, Slack-, AWS-SNS-HMAC-, KnoxCall-legacy-, or custom-header format. The killer test: Stripe's own SDK verifies our Stripe-format output end-to-end.

Send

Ephemeral Proxy

Proxy any HTTPS request without registering a Route first. Same secrets injection, same SSRF guard, same audit. Built for agent runtimes and one-shot integrations.

Ad-hoc

Replay Protection

Every signed format with a timestamp gets a configurable replay window (default 5 min, Stripe / Slack convention). Captured-and-replayed webhooks get replay_window_exceeded — verified once, never again.

Defence

AI Gateway

The AI Gateway Proxy your security team can sign off on.

Pillar 5. DPoP-bound capability keys, streaming PII redaction, per-agent budgets, prompt firewall, HIPAA / PCI / GDPR compliance packs — composed from primitives KnoxCall already audits.

Capability Keys (DPoP)

kc_live_a_… with capability scopes. RFC 9449 binds tokens to keys in the OS keychain — stolen tokens without the private key are inert. Refresh rotation invalidates the entire family on reuse.

Auth

Streaming PII Redaction

Hold-back FSM with 96-char sliding buffer. PII split across SSE chunks is detected at sentence boundaries before any token leaks downstream. Bedrock punts. Cloudflare buffers. We solve it.

Compliance

Cost Budgets & Attribution

Per-agent daily / monthly USD caps. Pricebook lookup post-flight. X-KC-User header pins spend to an employee + team. Block / warn / fall-back to a cheaper agent on overage.

FinOps

Prompt Firewall + Canary

Heuristics catch obvious "ignore previous instructions" patterns in microseconds. Per-tenant canary tokens injected into system prompts trip a critical alert on extraction.

AppSec

Compliance Packs

HIPAA Safe Harbor (18 identifiers + MRN formats), PCI (PAN + CVV + ABA), GDPR (EU national IDs + RTBF), SOC 2 — one-click recognizer sets, retention, audit alerts, route templates.

Procurement

10 Config Generators

Cursor / Claude Code / Cline / Continue / OpenAI SDK (Py + Node) / Anthropic SDK (Py + Node) / generic OpenAI- + Anthropic-compatible. Drop a JSON to add a new tool.

Comparison

Traditional vs KnoxCall

Before

Without KnoxCall

  • × Hundreds of .env files, each a potential security leak
  • × Developer leaves -- panic rotate all credentials -- hope you found them all
  • × No idea which systems are still using old keys until they break
  • × Manual OAuth token refresh logic in every service
  • × Building custom rate limiting and security layers
  • × Compliance audits require weeks of documentation gathering
  • × Mobile app secrets exposed through reverse engineering

After

With KnoxCall

  • ✓ Single source of truth: all credentials in encrypted vault, no .env files
  • ✓ Developer leaves -- rotate once in UI -- instantly applies everywhere
  • ✓ Real-time visibility: see exactly which services use which credentials
  • ✓ Automatic OAuth token refresh handled by KnoxCall
  • ✓ Built-in rate limiting, request signing, DDoS protection
  • ✓ Compliance reports generated automatically, audit-ready
  • ✓ Client credentials never touch your frontend code
