What our shortlists say about the one we picked.
Best for: Imperva WAF customers adding API discovery
Imperva earns a spot because it catches one user reading another user's data as it happens and can block it inline through the WAF you may already run. It suits you best if that WAF is Imperva Cloud WAF or WAF Gateway, and its self-managed option helps on hybrid estates. Imperva is now part of Thales, so check the roadmap and support model after that move.
