Your Sensitive APIs Are Vulnerable to MITM Attacks
73% of organizations experienced man-in-the-middle attacks in 2023. Traditional API authentication methods expose your sensitive routes, payment endpoints, and user data to interception and manipulation.
The Problem
- ✗Static API keys can be intercepted and reused by attackers
- ✗No integrity verification - attackers can modify requests
- ✗No authenticity checks - anyone with a key can access your APIs
- ✗Sensitive routes exposed - payment, user data, admin endpoints vulnerable
- ✗Replay attacks - intercepted requests can be reused
KeyClaim Solution
- ✓Challenge-response validation - cryptographic proof of authenticity
- ✓Integrity guaranteed - HMAC-SHA256 ensures requests aren't modified
- ✓Authenticity verified - only clients with secret keys can generate valid responses
- ✓Protects sensitive routes - payment APIs, user data, admin endpoints secured
- ✓Replay protection - one-time use challenges prevent reuse
Protect Your Sensitive Routes & APIs
KeyClaim ensures integrity and authenticity for your most critical endpoints:
How We Prevent MITM Attacks
Interactive visualization of our challenge-response validation system protecting your APIs
Client Requests Access
Your application requests access to protected API endpoints
Secret Never Transmitted
API keys stay secure on your server
30-Second Expiration
Challenges expire quickly, preventing reuse
One-Time Use
Each challenge can only be used once
Secure Flow (With KeyClaim)
Challenge-response validation ensures only authenticated clients can access your API. Each request is cryptographically verified.
MITM Attack Blocked
Without valid challenge-response validation, the attacker cannot generate the correct HMAC. The request is rejected before reaching your server.
