Security incident on recordImperva disclosed breach Sept 2023 — API keys, SSL certs, and customer data exposed after cloud provider misconfiguration

Editorial verdict

Imperva API Security delivers the most seamless WAF and API security integration in the market. For organisations already running Imperva WAF, adding API security creates a unified application protection platform where web application and API threats are detected, correlated, and responded to from a single console without the integration overhead of connecting separate tools. The 4.5 out of 5 Gartner rating from 72 reviews with consistent praise for API traffic visibility and WAF integration reflects genuine customer satisfaction with this use case.

The AI-native detection sophistication for API-specific threats like BOLA, BFLA, and business logic abuse is less advanced than Salt Security or Traceable.

The verdict: Imperva API Security is right for existing Imperva WAF customers wanting integrated API security without deploying a separate vendor. Organisations wanting best-of-breed standalone API security should evaluate Salt Security or Akamai.
