Securing Halcyon Mutual's legacy estate while it is modernized: a portfolio of 200 legacy systems triaged by exposure and criticality to pick the 15 the budget can move this year; the exposure while systems wait — 40 servers on Windows Server 2008, a hard-coded database password, mainframe gateways on a flat network — isolated, compensated and vaulted; the eight-station modernization rail from discovery, triage, isolation and compensating controls through modernization paths, migration, identity and data cutover to decommission; and a decommission proven complete, with a certified NIST 800-88 wipe, closed contracts and vendor access, removed DNS, certificates and firewall rules, and archived proof.
