ISTARI is a four-year-old cybersecurity advisory firm built on a Temasek-backed model focused on whole-of-organization resilience strategies. The tech stack reveals an Azure-native, cloud-first operational footprint with heavy Microsoft tooling (Defender, Sentinel, Front Door), plus early AI adoption (Claude, Copilot, Cursor) — consistent with their stated push into AI-powered internal tools for advisory work. Active hiring skews security and executive roles, with one engineering hire and a NetSuite implementation underway, signaling both advisory scaling and back-office infrastructure modernization as near-term priorities.
