Summary

Interface Security Systems

United States of America · AI-generated

security business us infrastructure

ISS-01 is operated by Interface Security Systems LLC.

What it's used for

  • The address space carries the netname WESTEC with registrants listed as Westec Security, Inc. and ISS-Tech.
  • The AS announces 1536 IPv4 addresses across 5 prefixes and maintains 6 observed neighbours, indicating a small-scale corporate or business network rather than a transit or large access provider.
  • Traffic from this AS consists of endpoints for Interface Security Systems, a provider of security system monitors and related services.

Notable

  • Registrants for all announced prefixes are Westec Security, Inc. and ISS-Tech, which aligns with the AS holder Interface Security Systems LLC given the historical connection between Westec Security and Interface Security Systems.
  • The address inventory is composed of five contiguous or near-contiguous /24 and /23 blocks within the 204.27.0.0/16 range.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
