Turkey · AI-generated

business enterprise security

The AS handle PRISMACSI is held by Brandefense Bilisim Danismanlik Sanayi Ve Ticaret Anonim Sirketi.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname BRANDEFENSE-TR-20261003 and registrant Brandefense Inc.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network
  • Traffic from this AS represents office workers and web/API endpoints for a business focused on IT consulting and security services

Notable

  • Registrants align with the announcer, listing Brandefense Inc. and Tres Teknoloji Network Group
  • The address inventory is minimal, comprising a single /24 block and a single /48 prefix, consistent with a small enterprise footprint

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
