Discover, Monitor, and Protect Every API in Your Environment
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.
What RLM Delivers on API Security
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.
How We Approach API Security
A structured path through the API Security decision — current-state discovery, shortlist and benchmark, commercial negotiation, then support until it is actually working.
API Discovery & Inventory
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.
API Security Platform Evaluation
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.
API Security Program Design
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.
OWASP API Top 10 Remediation
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.
API Security Evaluation Criteria
Before committing to any API Security platform, these are the points worth forcing a straight answer on.
Shadow API Coverage
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.
Runtime vs. Testing-Only
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.
OWASP API Top 10 Coverage
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.
Authentication & Authorization Testing
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.
Rate Limiting & Abuse Detection
API abuse — credential stuffing, scraping, and enumeration attacks — requires rate limiting and behavioral analysis. Evaluate abuse detection capabilities beyond simple rate limiting.
API Gateway Integration
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."
The benchmark comes first. Without a baseline, “savings” is just a number a vendor gave you.
Where This Matters Most
Sector-specific considerations we see repeatedly in security engagements.
A Sample of the Security Providers We Evaluate
RLM is vendor neutral. These are among 600+ providers in our evaluation set — inclusion here is not an endorsement, and we are paid by the provider you choose, not by any provider in particular. How that works →
