Microsoft makes security and privacy a priority at every step, from code development to incident response.
Security and privacy are built into the Azure platform. The Security Development Lifecycle (SDL) addresses security at every development phase, from initial planning to launch. Microsoft updates Azure continually to make it more secure. Operational Security Assurance (OSA) is an additional framework that ensures secure operations throughout the lifecycle of the cloud-based service. Azure is the only public cloud platform to offer continuous security-health monitoring.
