Siriux, now a part of Vectra, operates in the cybersecurity sector, focusing on enhancing the security of Microsoft 365 (M365) configurations. The company has developed a pioneering tool that scans and evaluates M365 settings to identify vulnerabilities. This tool is particularly valuable because many security settings in M365 are not easily accessible through standard Microsoft admin portals and require specialized knowledge to manage effectively.

Siriux primarily serves businesses that use M365, including private equity firms and other organizations that handle sensitive data. These clients are often unaware of the security risks posed by default M365 settings, which can leave them vulnerable to cyberattacks. Siriux's solution addresses this critical need by providing a comprehensive assessment of M365 configurations, identifying potential security gaps, and offering expert recommendations to mitigate these risks.

The market Siriux operates in is the Software as a Service (SaaS) security space, which is growing rapidly as more businesses adopt cloud-based solutions. The company's business model revolves around offering its M365 scanning tool as a service. Clients pay for the tool to scan their M365 configurations, and Siriux generates revenue through these service fees. Additionally, the company provides consulting services where its analysts offer tailored security recommendations based on the scan results.

Siriux makes money by charging for its scanning tool and the accompanying expert analysis. This dual revenue stream not only helps businesses secure their M365 environments but also positions Siriux as a trusted advisor in the cybersecurity landscape.

In summary, Siriux is a cybersecurity firm specializing in M365 vulnerability assessments, serving businesses that rely on M365 for their operations. The company operates in the SaaS security market and generates revenue through service fees for its scanning tool and consulting services.
