Cysiv SOC-as-a-Service combines all the elements of a modern 24/7 SOC—including a cloud-native next-gen SIEM platform, a team of experts, actionable threat intel, SLAs and runbooks, and an optional managed security stack—and delivers them as a service, with monthly, consumption-based billing.

A 24/7 security operation center (SOC) that’s focused on fast, accurate detection and response to cyber threats is an essential part of a security strategy for organizations of all sizes. But the high cost, complexity and frustration of building, staffing and operating an effective one, put this beyond the reach of all but a few organizations.

And other approaches to threat detection and response, including those offered by traditional MSSPs, and MDR service providers are less than ideal for many organizations.

Standard security controls like firewalls, anti-virus and IAM are essential, but aren’t 100% effective or reliable. Cysiv SOC-as-a-Service complements these, and helps further reduce the risk of a damaging data breach or service disruption, while ensuring compliance.

Cysiv Command is their massively scalable, modern SOC platform. It is a next-gen SIEM that addresses the limitations and frustrations associated with traditional SIEMs and other products typically used in a SOC.
