Notes — Imperva (a Thales Group subsidiary) provides DDoS protection and application security services. SLA uptime is measured ANNUALLY — 99.999% for Network Infrastructure and 99.95% for Protected Infrastructure. The claim window is critically short: credits must be requested within 7 days of the incident, not from billing cycle end. Credit amounts require direct review of the SLA document.
