Resilient and reliable IT systems are crucial for modern businesses, particularly in the financial sector, where outages can have significant consequences. Recent global regulations such as the Digital Operational Resilience Act (DORA) in the EU, APRA CPS 230 in Australia, and FCA PS21/3 in the UK have been introduced to enhance IT operational resilience and risk management. These regulations require companies to perform regular operational resilience testing, document and test Business Continuity and Disaster Recovery plans, verify monitoring and incident response processes, map third-party dependencies, and meet performance obligations. Gremlin offers a platform that helps organizations automate and standardize these processes by simulating failures in a controlled environment, providing documentation and reporting for compliance. This enables companies to transition from manual checklists to automated, verifiable compliance, ensuring their systems maintain minimum operational standards during failures, thereby supporting both compliance and operational resilience.
