Resilient Systems

Resilient Systems

Resilient Systems was founded in 2010 in Cambridge, Massachusetts, by John Bruce and Ted Julian. The firm set out to professionalize cyber incident response with a platform that transformed ad-hoc recovery processes into automated, repeatable workflows. The software integrated with existing security infrastructure, giving analysts a unified cockpit for managing detection, investigation, and remediation. The flagship Resilient Incident Response Platform (IRP) targeted large enterprises and government agencies. It codified response plans into executable playbooks, pulling in threat intelligence from IBM X-Force, FireEye, and other providers while enforcing regulatory compliance requirements. Confirmed deployments included Fortune 500 financial institutions and a major U.S. intelligence agency. The firm's model blended a core SaaS platform with professional services for incident-readiness assessments and tabletop exercises. The company raised roughly $25 million from investors including Fairhaven Capital and Polar Ventures before its 2016 exit. After acquisition, the platform became the foundation for IBM Security's SOAR business. The Cambridge headquarters housed engineering and product teams that continued to operate within IBM's security division post-acquisition. Resilient Systems carved its structural edge by focusing exclusively on the response phase of the cyber kill chain. While most peers concentrated on prevention or detection, the firm built a system of record for the moment after compromise — a deliberately narrow mandate that became the reference architecture for an entire product category.
