Summit Insurance Group blocked a $3.4M ransomware attack and passed NYDFS 500 on the first try with AI security posture management
A multi-state insurer holding 2.1 million policyholder records was drowning in 9,000 alerts a day and 90 days from a NYDFS 500 cybersecurity audit. An AI security posture platform caught an active ransomware deployment in week one, collapsed alert noise by 81%, and turned audit prep into a continuous, audit-ready state.

Where they started
Summit Insurance Group's 3-person security team was getting 9,000 alerts a day from a stack of disconnected tools — SIEM, EDR, cloud posture, email gateway — none of which talked to each other. Real threats were getting missed in the noise; an external pentest had found a domain admin credential sitting in a helpdesk ticketing system for 6 months. Summit held 2.1 million policyholder PII records across 11 states, and the New York DFS Cybersecurity Regulation (23 NYCRR 500) audit was 90 days out — a failed audit would have meant fines and a public consent order. The CISO was about to hire a 4th analyst just to keep up with alert triage, and the cyber insurer was threatening to double the premium.
What we built
We deployed our Aegis AI security posture platform with AI-driven alert prioritization that scores every alert against Summit's actual environment, automated SOAR playbooks that quarantine compromised endpoints and revoke stolen sessions in seconds, continuous compliance mapping that ties every control to NYDFS 500 requirements in real time, and a policyholder-data classification engine that flags over-exposed PII automatically. The platform ingested Summit's existing tool outputs so there was no rip-and-replace. In the first week, the AI caught an active ransomware deployment on an underwriter's laptop — the encryption payload had staged but not yet fired — and the SOAR playbook isolated the host before it could spread.
Target outcomes
More from this project
Week one, the platform caught a ransomware payload that had already staged on an underwriter's laptop — our old tools had missed it completely. We passed the NYDFS audit without a single finding, and our cyber insurer dropped the premium instead of doubling it. We never did hire that 4th analyst.
