Data Theorem API Secure

Data Theorem brings a unified application security testing perspective to API security, combining API discovery and testing with the vendor's established mobile and web application security scanning heritage into one platform. For organisations that have historically run separate point solutions for mobile, web, and API security, consolidating onto one vendor with shared context reduces tool sprawl and the risk of gaps where these surfaces overlap, such as a mobile app's backend APIs.

The honest positioning is that core strength sits in testing rather than active runtime blocking.

The verdict: right for organisations wanting unified security testing across APIs, mobile, and web applications from one platform. Organisations needing dedicated runtime protection should evaluate Salt Security or Traceable AI instead.
