LEO Cyber Security

LEO Cyber Security is a boutique cybersecurity advisory and operations firm based in Dallas, Texas, founded in 2016. Its service lineup covers the range typical of a small MSSP/consultancy hybrid: digital forensics, threat hunting, incident response, managed detection and response (MDR), and virtual CISO services for organizations that want senior security leadership without a full-time hire.

The company positions itself around deep practitioner experience rather than a proprietary technology platform, describing its team as veteran cybersecurity operators rather than a product engineering organization. With roughly 11-50 employees, LEO operates at a scale where its value proposition is closer to a specialized consultancy than a scaled managed-services provider competing on breadth of coverage.

Public information on LEO’s specific client base, case studies, or third-party performance evaluations is limited — there is no publicly available MITRE ATT&CK evaluation, named enterprise case study, or independent audit of its incident response or MDR outcomes in the sources reviewed for this profile. That is common for small, privately held advisory firms that work under client confidentiality, but it also means most of what can be said about LEO’s effectiveness rests on its own service descriptions rather than independently verifiable evidence.
