The Big Five of the CSIRT Cybersecurity Incident Response Team

At Bigfive, we have a dedicated cybersecurity incident management and response team (CSIRT), available 24/7. The CSIRT works in coordination with our Security Operations Center (SOC) to ensure comprehensive protection, responding quickly and accurately to any threat and continuously strengthening the resilience of our clients’ critical technology environments and our own infrastructure.

Bigfive’s CSIRT is governed by internationally recognized best practices and guidelines, inspired by frameworks such as NIST SP 800-61r2, ISO/IEC 27035, ISO/IEC 27001, and FIRST. This operating model enables a structured, agile, and constantly evolving response to cybersecurity incidents, protecting critical technological environments of the organization and its customers.
