HOW IT WORKS
Around the core WAF it bundles DDoS mitigation, a CDN, dedicated API security, and advanced bot management, plus attack analytics that correlate events to cut alert noise. That breadth, and its compliance track record, make it common in regulated industries.
Imperva is an enterprise platform priced by quote and sold with onboarding and support, not a self-serve product. Smaller sites are better served by a site-owner cloud WAF; Imperva targets organisations that need depth, on-prem options, and formal support.
Category context: Edge and cloud WAF platforms for larger sites and APIs, with managed rules, bot defence, and DDoS at global scale. Usually custom-priced.
