Summary

Sovos Compliance

United States of America · AI-generated

business compliance software

CNV-MTK-CORP is operated by Sovos Compliance, LLC.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to sovos.com and the netname US-TWDX-185-134-183-0-1.
  • The AS announces a single IPv4 prefix of 256 addresses with one observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints for a company providing tax compliance software and services, including 1099 reporting and fleet management solutions.

Notable

  • The RDAP registrant is Sovos Compliance, LLC, which aligns with the reverse DNS evidence, while the registry holder remains Convey Compliance Systems, Inc.
  • Convey Compliance Systems, Inc. was acquired by Taxware LLC, a portfolio company of Vista Equity Partners; the combined entity later rebranded to Sovos Compliance in 2015.
  • The inventory consists of a single /24 block, representing a compact internal estate for the organization's operational needs.

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 1,778 prefixes, as published 2026-10-20. 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.
