A Service Level Agreement (SLA) is a formal contract between a service provider and a customer that defines the expected level of service, including performance metrics, availability targets, response times, security obligations and remedies for non-compliance. SLAs provide a measurable basis for evaluating service quality and create accountability for both parties.
In the context of information security and compliance, SLAs are critical for managing third-party risk. They should specify data protection responsibilities, incident notification timeframes, audit rights and business continuity commitments. Organisations should regularly review SLA performance against agreed metrics and ensure that penalty clauses provide genuine incentive for the provider to maintain the required service levels.
