Exigence Platform-Based Incident Response Planning is a purpose-built, out-of-band platform designed for creating, testing, and executing incident response plans. It targets MSPs, MSSPs, and enterprise security and IT teams. The platform enables users to build IR plans using pre-defined templates, forms, checklists, and timers, streamlining the plan creation process. It supports guided tabletop exercises to test IR plans, procedures, and engage all incident stakeholders for team training. A key architectural feature is out-of-band availability, meaning responders retain access to the platform even when the primary network is compromised or unavailable. The platform is multi-tenant, supporting multiple enterprise sites or MSP/MSSP clients from a single instance. The platform includes GenAI capabilities for generating incident summaries and surfacing similar past incidents. It is described as open and system-agnostic, accessible on any device type. Exigence holds ISO 27001 and SOC 2 Type 2 certifications. The platform is built to scale, with the vendor citing hundreds of thousands of incidents and tens of thousands of users handled across its architecture.
