Expert-Led Managed Cybersecurity, Compliance, and Risk Services in One Unified Program

CISO Global is a managed cybersecurity, compliance, and software company headquartered in Scottsdale, Arizona, serving organizations in energy, healthcare, financial services, federal contracting, and state and local government. Founded in 2015 by David Jemmett as Cerberus Cyber Sentinel Corporation, the company rebranded to CISO Global in May 2023 and trades publicly under the ticker CISO. Its pitch is expert-led services and purpose-built software delivered as one unified security program rather than a collection of disconnected point engagements.

The operating model pairs a 24/7 security operations center — delivering managed detection and response, SIEM, and incident response — with consulting arms for risk and compliance, secure managed IT, vulnerability assessment, and penetration testing. Layered on top is a proprietary software portfolio: Argo Security Management for real-time security intelligence across client environments, CHECKLIGHT endpoint security monitoring aimed at smaller businesses, TiGRIS for enterprise governance, risk, and compliance management, and SurfaceWatch for monitoring external exposure. Clients consume these as an integrated program spanning tens of thousands of endpoints, users, and cloud assets.

Differentiation rests on a deliberately technology-agnostic posture: rather than reselling a single stack, the firm assembles subject-matter experts — much of the team built through acquisitions of specialist consultancies — and fits tooling to each client's environment. The company reports a 93 percent client retention rate and states it has observed and disrupted over one billion attacks across client environments. It holds SOC 2 certification, with staff credentials spanning GIAC, AWS, Cisco, Microsoft, and VMware, positioning it as a mid-market and public-sector alternative to larger MSSPs.
