A Managed Service Provider (MSP) handles general IT operations like helpdesk support, network management, and infrastructure maintenance. A Managed Security Service Provider (MSSP) specialises in cybersecurity—threat monitoring, incident response, vulnerability management, and compliance. Many businesses need both. Mercury IT operates as both MSP and MSSP, providing integrated IT and security services so your technology and protection work as one unified system rather than separate silos with gaps between them.
