A Service Level Agreement (SLA) is a contract between a service provider and its customer that outlines the expected level of service, including performance metrics, responsiveness, and responsibilities. In cybersecurity, SLAs often define the standards related to security measures, uptime, incident response times, and other related services. These agreements are critical for setting expectations, establishing performance benchmarks, and ensuring accountability. Violation of an SLA can lead to penalties, reduced fees, or termination of services, making them a vital tool in managing and measuring service delivery. In cybersecurity contexts, SLAs often cover areas like cloud service security, data protection guarantees, response times for security incidents, and system availability or uptime.
