API Security Pricing FAQ

01 What is API security software?

API security software discovers, tests, and protects an organization's APIs against attacks like injection, broken authentication, and data exposure. It maps your full API inventory (including shadow and zombie APIs), tests for vulnerabilities in development, and monitors runtime traffic to detect and block abuse and data leakage.

02 How much does API security cost?

API security platforms are typically priced by the number of APIs or endpoints protected, API traffic volume, or environments, with most vendors quoting custom enterprise pricing. Costs scale with your API footprint and traffic. Expect a platform subscription plus possible add-ons for testing, runtime protection, and posture management.

03 Why isn't a WAF enough to secure APIs?

Traditional web application firewalls focus on common web exploits and struggle with API-specific risks like business-logic abuse, broken object-level authorization, and excessive data exposure. Dedicated API security adds full API discovery, context-aware testing, and behavioral runtime detection that a generic WAF can't provide.

04 What hidden costs come with API security?

Watch for pricing that scales with API count or traffic as your estate grows, integration effort across gateways and CI/CD, and the staffing needed to triage findings. Bundling discovery, testing, and runtime protection from one vendor can cost more than expected if priced as separate modules.
