Summary
CIASC - Centro de Informatica e Automacao do Estado de Santa Catarina
government legacy
AS11802 belongs to CIASC, the Centro de Informática e Automação do Estado de Santa Catarina — the state-owned IT company of Santa Catarina, Brazil, based in Florianópolis. Founded in 1975 as PRODASC and converted to a wholly public company in 2005, it is the body that runs information-technology and e-government services for the state administration.
What it's used for
Public-sector service delivery, not commercial connectivity. RIS observes 4 IPv4 prefixes totalling 12,288 addresses, 2 IPv6 prefixes, and 4 observed neighbours — a modest, multi-homed footprint sized for hosting applications rather than carrying transit. All four IPv4 blocks are registered through LACNIC to CIASC itself, so registrant and announcer are the same entity with nothing third-party in between.
What the space carries is government systems for Santa Catarina at every level CIASC serves — state executive agencies, and by extension the municipal and judicial bodies that contract it for data processing and hosting. The one reverse-DNS record sampled points at a sc.gov.br municipal-government host, which is consistent with a state IT company that also runs services on behalf of city administrations rather than only its own.
Notable
Brazilian states routinely run these empresas de processamento de dados — CIASC in Santa Catarina, and equivalents in most other states — as public companies with their own ASNs and data centres. In 2026 CIASC was formally recognised as a Scientific, Technological and Innovation Institution, which broadens its remit beyond straightforward government IT operations.

Reputation
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
