Advisory-first cybersecurity services.

Four families of engagement: objective technical work, sustained executive advisory, investor diligence, and go-to-market advisory for cybersecurity companies.

Standalone Cybersecurity Services

Objective & technical engagements

Foundational Cyber

Offensive security testing, independent cybersecurity assessments, and governance, risk & compliance work that establishes the factual baseline every downstream decision depends on. We validate what is actually exploitable, benchmark controls against the frameworks your regulators and customers expect, and turn findings into prioritized, business-relevant actions, including focused diligence for M&A.

OffSec & PentestingCybersecurity & M&A Assessments

Ecosystem-Specific

Specialized control reviews for the environments where a generic assessment falls short: operational technology and industrial control systems, the crown-jewel assets your business cannot operate without, and cloud posture across providers. We tailor scope and methodology to the realities of each ecosystem rather than forcing a one-size-fits-all checklist.

Emerging Cyber & AI

Forward-looking defense for threats that are still over the horizon for most organizations: adversarial and model-level AI risk, security architecture for the AI systems you are building or buying, and post-quantum cryptography readiness so your data stays protected against tomorrow’s compute.

Assessment & Validation Programs

Move from point-in-time assessments to a continuous, measured program. We tailor recurring assessments and enterprise risk management to your environment, quantify exposure in financial terms, and trend it over time so you can prove risk is actually going down. Our Risk Management Program packages this into tiers, with the tooling included.

Deal diligence & portfolio risk oversight

Investor Cybersecurity Advisory

Cyber diligence and advisory that de-risks high-stakes investment decisions and transitions. We assess targets before you commit, surface the issues that move valuation or deal terms, and translate technical findings into clear investment-committee language, with post-close support through integration.

M&A AssessmentsCyber Investment Due Diligence

Private Equity Cybersecurity Advisory

Portfolio-wide cyber oversight for firms managing diverse holdings: standardized assessments across companies, aggregated portfolio risk reporting for the fund, and fractional CISO / vCISO support for portfolio companies that lack senior security leadership.
