Summary

Imperva (Incapsula)

Global · AI-generated

security waf cdn

Imperva's Incapsula network (INCAPSULA) — a cloud security service that fronts customer websites with a WAF, DDoS mitigation, and CDN.

What it's used for

  • Reverse-proxying and protecting customer sites: filtering attacks and bots, absorbing DDoS, and caching content at the edge.

Notable

  • Like Cloudflare or Akamai's security edge, an IP here is a protective proxy in front of a site — it identifies Imperva, not the origin server or its true location.
  • Used mostly by enterprises for web-application security.

Interesting

  • Because it sits in front of many different customers, one Incapsula IP can front numerous unrelated websites.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
