Cybersecurity Due Diligence for Private Equity: A Practitioner's Checklist

Cybersecurity due diligence used to live in the same bucket as data-room legal review: a checkbox owned by the firm's tech-DD vendor, scoped narrowly, and treated as a procedural step that rarely changed deal terms.

Five priority points from the full essay:

▸ Cyber DD treated as a checkbox produces clean reports and material post-close surprises; cyber DD treated as a value-shaping discipline produces actionable findings that change deal structure.
▸ The five priority questions are about asset visibility, third-party access, segmentation, monitoring, and incident response — same priority order whether the target is industrial, SaaS, or services.
▸ Material exposure rarely surfaces in the data room. It surfaces in the gap between what the vendor's report says and what the target's operations actually do.
▸ Post-close integration risk is typically the biggest unmitigated cyber exposure in PE-owned platforms — and almost never appears in pre-close DD reports.
