A SOC service is a security operations capability that monitors an organization’s technology environment for suspicious activity, investigates potential threats, and coordinates response. A managed SOC provides these functions through an external security partner rather than requiring the organization to staff and operate every SOC function internally. DeepSeas supports continuous monitoring across endpoint, network, cloud, identity, email, SaaS, and OT environments.
