A virtual SOC (security operations center) model offers continuous system monitoring to improve an organization’s security posture. There is also a virtual SOC solution, which offers the same capabilities, but is a web-based tool that can be outsourced to simplify and speed up work for the in-house security team. The most essential component is a cloud-native platform that integrates essential technologies (SIEM, SOAR, UEBA, threat intel platform, case management) into a single unified SaaS.
