A service provider in cybersecurity refers to a company or organization that delivers technology-based services, solutions, or support to other businesses or individuals. These services can include managed security services, cloud computing, network management, data storage, or IT support. Service providers help organizations maintain their IT infrastructure, secure their digital assets, and ensure compliance with industry standards. They often offer expertise and resources that client organizations may lack internally, allowing businesses to focus on their core operations while relying on the service provider for specialized technical support and security.
