API security addresses the fastest-growing attack surface in modern applications — discovering undocumented and shadow APIs, detecting API abuse and data exfiltration through API channels, and enforcing authentication and rate-limiting controls that prevent the API attacks that traditional WAFs and network controls miss.
APIs are the primary attack surface of modern applications — and most organizations don't know how many APIs they have, who's calling them, or whether they're properly secured. API security provides the visibility and protection layer that application and network security tools weren't designed to provide.
A structured advisory process — from security posture assessment and market evaluation to vendor selection, contract negotiation, and post-deployment validation — tailored to your risk profile and compliance obligations.
We assess your API landscape — conducting discovery across your applications, microservices, and third-party integrations to build the comprehensive API inventory that's the prerequisite for meaningful API security.
We evaluate API security platforms — Salt Security, Noname Security, 42Crunch, Traceable, and API gateway-native security capabilities — against your API volume, authentication requirements, and the runtime protection depth required for your threat model.
We design the API security program — authentication standards (OAuth 2.0, API keys, mTLS), authorization model, rate limiting architecture, and the schema validation approach that blocks malformed requests.
We assess your APIs against the OWASP API Security Top 10 — broken object level authorization, broken authentication, excessive data exposure, and others — and design the remediation approach for identified vulnerabilities.
These are the dimensions that consistently separate effective security programs from expensive ones — and the questions RLM will help you answer before any vendor commitment.
Organizations consistently underestimate their API inventory. Evaluate the platform's ability to discover undocumented and shadow APIs — APIs built by development teams outside of centralized governance that represent unknown attack surface.
Some API security tools only test APIs; others provide runtime threat detection for production traffic. Evaluate whether runtime protection is required for your most sensitive APIs alongside pre-production testing.
The OWASP API Security Top 10 defines the most critical API vulnerabilities. Evaluate coverage and detection quality for each OWASP category — particularly BOLA/IDOR (broken object-level authorization), which is the most common API vulnerability.
Weak API authentication is a primary API vulnerability. Evaluate the platform's ability to test authentication bypass, token validation weaknesses, and privilege escalation through API endpoints.
API abuse — credential stuffing, scraping, and enumeration attacks — requires rate limiting and behavioral analysis. Evaluate abuse detection capabilities beyond simple rate limiting.
API gateways (AWS API Gateway, Kong, Apigee) provide the enforcement point for API security policies. Evaluate the integration depth between API security tooling and your specific API gateway for centralized policy enforcement.
"RLM helped us build a security program that satisfied our board and our auditors — without locking us into a single vendor's roadmap. Their independence is the whole point."
"We had three overlapping security tools doing the same job. RLM helped us rationalize the stack, cut spend by 30%, and actually improve our detection coverage in the process."
