Summary
SIBS Forward Payment Solutions
enterprise finance legacy
SIBS Forward Payment Solutions, S.A. is Portugal's interbank payment services company, owned by the Portuguese banks and best known for running the Multibanco ATM and card network and the MB WAY mobile payments service.
What it's used for
- The corporate and payments-processing network of SIBS itself. The announced space is a contiguous run of prefixes out of
195.138.0.0/21and neighbouring/24s, all registered under the netnameSIBS. - No subscriber or hosting reverse DNS appears in the space: this is a financial institution's own network, not a service sold to third parties.
Notable
- Registry records still carry the company's former name, SIBS Sociedade Interbancaria de Servicos, and its old Lisbon address on Rua Soeiro Pereira Gomes, while the organisation record uses the current name and its Amadora headquarters. Automated ASN lists that read the wrong field sometimes end up showing a street address as the operator's name.
- Multibanco is one of the most heavily used national payment networks in Europe relative to population, which puts a payments processor behind an early ASN that most people will never knowingly connect to.

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: 443 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.
