At Datadog, integrating Site Reliability Engineering (SRE) and security is crucial to ensure the cloud-based development environment's security. Combining these disciplines has enabled the company to apply practical SRE solutions to security challenges, unifying all aspects of its operational and security posture. This approach has strengthened incident response, improved risk management, and enhanced overall system resilience. By merging SRE and security teams into a single organization, Datadog can inject in-house security expertise into well-established SRE practices, foster a culture of continuous improvement, and enrich its security culture by breaking down silos between development, operational, and security teams. The combined approach has led to improved log governance, auditing, and security control rollout, as well as enhanced security response through the creation of detailed security incident playbooks and training for on-call leads and engineers.
