Leviathan Security Group, a K2 Integrity company, provides expertise across information security, governance, risk and compliance, threat modeling, secure development, and information policy.

We assess your organization's tolerance for risk and provide clear insight into your technology operations, development practices, and security management programs. Leviathan delivers a broad range of cybersecurity services spanning low-level technical engineering through strategic business consulting.

Our methodology is grounded in measurable facts and field-tested expertise. Our consultants are recognized globally for their research, technical leadership, and practical experience.
