### OT / ICS Security

Risk assessments, asset inventory, network segmentation, and continuous monitoring for utilities, energy providers, and water systems.

### Security Architecture & Consulting

Zero Trust design, cloud security, strategic network consulting, and cyber insurance guidance — using open-source and premium tools matched to your needs.

### Pentest & Vulnerability Assessment

Penetration testing and continuous attack surface scanning to find security gaps before attackers do, with actionable remediation guidance.

### Compliance & Regulatory

HIPAA, CMMC, and industry-specific regulatory audits, policy development, and ongoing compliance management for healthcare, government, utilities, legal, and financial organizations.

## We Find What Others Miss

Our research team conducts continuous security assessments across public infrastructure, critical systems, and enterprise environments. Every finding is disclosed responsibly — and has directly improved security for organizations at every level of government and industry.

- 28+ Formal vulnerability disclosures to state & federal programs

- 70+ Entity-level security assessments delivered

- 13 Responsible disclosure notifications to critical infrastructure operators

- 3 Published security advisories affecting multi-site vendor platforms

Formal disclosures are reports filed through state and federal vulnerability disclosure programs. Critical infrastructure notifications went directly to the affected operators. The figures are reported separately.
