Summary
SECOM Trust Systems Co., Ltd.
SECOMTRUST is SECOM Trust Systems Co., Ltd., the ICT arm of the SECOM group (Japan's largest private security company). Formed in 2006 from the merger of two SECOM IT subsidiaries, it runs data centres in Mitaka, Tokyo and sells managed hosting, cloud, disaster-resilience and certificate-authority services.
What it's used for
Data-centre and managed-network space. The AS announces 55 IPv4 prefixes totalling 146,176 addresses, including a legacy 150.67.0.0/16, plus two IPv6 /48s. Sampled reverse DNS is almost all first-party — 165-100-0-5.secomtrust.net, 61-114-176-5.secomtrust.net — the generic per-address naming a hoster gives to racked machines and customer VLANs, with no subscriber-pool markers (dsl-, ppp, dhcp) anywhere in the sample.
Notable
This is hosting / managed infrastructure, not an eyeball ISP. The tell is a third-party PTR sitting inside SECOM's own space: 210229000005.obic7.obicnet.ne.jp belongs to OBIC, a separate Japanese ERP vendor whose hosted service lives on SECOM's addresses. That is what customer-hosted estate looks like. It is also not a carrier: 18 observed BGP neighbours against 146k addresses is a provider that buys transit and peers modestly, not one that sells transit widely.
Interesting
SECOM Trust Systems operates a well-known Japanese certificate authority, so a slice of this space carries PKI and trust-service infrastructure. Treat addresses here as enterprise servers and managed customer environments, and do not attribute a workload on them to SECOM itself — the tenant is frequently someone else.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
