Capabilities
Four Disciplines.
One Standard.
Every engagement is scoped to the specific threat environment. No off-the-shelf solutions — only intelligence-driven, technically rigorous security consulting backed by operational discipline and hands-on architecture expertise.
Integrated Technical Security & Executive Protection
TSCM (Technical Surveillance Countermeasures)
Technical Security · Technical Executive Protection
A compromised environment is a compromised operation. Our TSCM discipline combines Technical Security and Technical Executive Protection to identify technical threats, protect sensitive environments, and reduce risk to critical information, assets, and personnel.
View capability →02Proactive Threat Assessment & Monitoring
Protective Intelligence
The most effective security is the threat that never materializes. Our Protective Intelligence capability provides proactive threat identification, monitoring, and assessment — drawing on intelligence community tradecraft to detect, analyze, and neutralize risks before they reach your principal or organization.
View capability →03Systematic Vulnerability Analysis
Security Risk Assessments
You cannot defend what you have not assessed. Our Security Risk Assessments provide a systematic, intelligence-informed evaluation of your organization's vulnerabilities across physical, technical, and human threat vectors — delivering a prioritized remediation roadmap grounded in real-world threat analysis.
View capability →04Zero Trust, Cloud-Native & Network Defense
Cybersecurity
Zero Trust & Microsegmentation · Cloud-Native & Runtime Security · Penetration Testing · Hardening & Remediation
Cyber risk rarely stays inside one layer. Our Cybersecurity capability combines federal-market security strategy with hands-on architecture across enterprise networks, cloud platforms, endpoints, and Kubernetes environments. We design practical zero-trust controls, expose workload risk with deep runtime visibility, and turn security findings into prioritized remediation that can be implemented and verified.
