These managed security services are designed to support organisations by outsourcing monitoring and management of security devices and systems. Some services may offer a range of different services, but typically include managed firewall, intrusion detection system (IDS), security information and event management (SIEM), endpoint detection and response (EDR), and vulnerability scanning. Managed security solutions often use high-availability security operations centres (SOC) which provide 24/7 security services designed to reduce the number of operational personnel an enterprise needs to hire, train, and retain to maintain an acceptable cyber defence.
