Summary

WolfSec

Switzerland · AI-generated

security business switzerland

The AS handle WOLFSEC-AS2 is held by WolfSec.

What it's used for

  • The address space carries infrastructure for WolfSec, evidenced by the netname WOLFSEC-INFRA-1 and reverse DNS entries pointing to wolfsec.com.
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour. This low neighbour count relative to the address inventory indicates a small, self-contained network rather than a transit provider.
  • As a security firm, the traffic consists of internal corporate endpoints, web/API services, and administrative infrastructure for the organization's operations in Zurich.

Notable

  • The RDAP registrant WolfSec Role Account aligns with the AS holder Stephan Roland Wolf and the WOLFSEC naming convention.
  • The address inventory is compact, consisting of a single /23 IPv4 block and a /29 IPv6 prefix, typical for a small private enterprise network.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
