AS11765 NETSURION-LLC-AS11765

NETSURION-LLC-AS11765 is Netsurion, a managed detection and response provider that sells a co-managed XDR platform and a 24×7 security operations centre. The company began as VendorSafe Technologies, a Houston firm selling PCI-compliant managed network security to multi-location retail and restaurant chains, took the Netsurion name in 2015, and was acquired by Lumifi Cyber.

What it's used for

The AS carries the company's own service infrastructure, and it is small: RIS sees a single IPv4 prefix, 216.99.210.0/23 — 512 addresses — no IPv6, and 1 observed BGP neighbour. One upstream and one block is not a network built to sell connectivity; it is an operator holding portable address space so its own platform endpoints keep stable addresses. For a security vendor whose customers whitelist its collectors and SOC egress, that stability is the point. The /23 registers to Netsurion itself, so there is no third-party or leased-inventory question to answer here.

Notable

The registry tells the acquisition story more plainly than the AS does. The ARIN org handle is VSTL — the VendorSafe name, kept through two rebrands — while the postal address is now Scottsdale, Arizona and the sole point of contact carries a lumificyber.com address. Handle, address and contact each belong to a different era of the same company.

Interesting

ARIN dates the AS number to 2013 and the org record to 2012. The low number is reissued space, not an early-internet allocation, and nothing about this network predates the company that holds it.
