API Security
Discover, test, and protect the APIs connecting your applications, partners, and AI systems.
Where this risk comes from
APIs are now the primary way applications, partners, and AI systems exchange data — which also makes them the primary way attackers get in. Traditional web application firewalls were never built to understand API-specific logic like broken object-level authorization or excessive data exposure.
Mellivor API Security maps your API footprint, including the APIs teams forgot they shipped, and applies controls that understand how APIs actually get abused.
What enterprises are up against
- Shadow and undocumented APIs outside the inventory security teams maintain
- Broken object-level and function-level authorization between API calls
- Excessive data exposure in API responses built for convenience, not least privilege
- Bot and credential-stuffing traffic that looks like normal API usage
What's actually at stake
Most API breaches don't involve exotic exploits — they involve an endpoint that returned more data than it should have, or an authorization check that only worked for the happy path. Those are the failures that scale silently until a researcher or attacker finds them first.
Undocumented and shadow APIs are frequently the ones causing the most exposure, precisely because no one is watching them.
The Mellivor approach
- Continuous discovery of first-party, third-party, and shadow APIs
- Runtime analysis of API behavior to catch logic-based abuse, not just malformed requests
- Schema and specification validation to catch data over-exposure before release
- Behind24 integration for real-time detection of anomalous API traffic
