Modern applications are built from APIs connecting mobile apps, partner integrations, internal microservices, and third-party services. That architecture enabled faster development, but it also created an attack surface that traditional web application firewalls were never designed to fully see, particularly APIs that were never registered with a central gateway.
Finding what you cannot secure without seeing
Shadow and zombie APIs—undocumented endpoints created for a forgotten project, or old versions left running after a supposed retirement—are consistently among the most exploited entry points, since they receive none of the monitoring or patching attention given to actively maintained services. Automated discovery that inventories every API actually receiving traffic, not just those documented in a registry, is a prerequisite for any real security program.
Beyond discovery, authorization logic deserves the most scrutiny: broken object-level authorization, where an authenticated user can access another user’s data simply by changing an identifier in a request, remains one of the most common and damaging API vulnerabilities in production.
JIG helps enterprises build API security programs starting with visibility, then layered authentication, rate limiting, and continuous testing.
