🏢 Managed Security Services

Managed security service providers (MSSPs) and managed detection and response (MDR) providers deliver outsourced security monitoring, threat detection, and incident response. This category includes SOC-as-a-service, 24/7 managed monitoring, threat hunting services, and co-managed security platforms. For organizations that lack the budget or staff to operate an in-house security operations center, managed security services provide enterprise-grade protection with predictable costs and rapid deployment.
