Governance, Risk & Compliance

Cybersecurity due diligence for mergers and acquisitions.

A target's cyber risk becomes your liability the day the deal closes. SubRosa assesses the security posture, compliance exposure, and breach history of the company you're acquiring, quantifies how it affects valuation, and hands your deal team a clear picture of the risk before you sign, not after.

What is cybersecurity due diligence?

Cybersecurity due diligence is the assessment of a target company's security posture, risks, and liabilities during a merger or acquisition. It examines the target's controls, compliance status, and breach history to surface the cyber risks that could affect the deal, from undisclosed incidents and regulatory exposure to the cost of bringing the acquired environment up to standard. Done before you sign, it protects your valuation and your integration; done well, it turns cyber risk from a hidden liability into a negotiated, quantified line item.

What we assess

From target risk to integration plan.

A complete cyber picture of the company you're acquiring, before and after close.

Pre-acquisition assessment

A comprehensive evaluation of the target's cybersecurity posture, controls, vulnerabilities, and breach history, so there are no surprises after close.

Compliance & liability review

Assessment of the target's regulatory compliance and potential legal exposure, so inherited liabilities are on the table during negotiation.

Risk-based valuation analysis

Analysis of how the target's cyber issues affect deal valuation and post-acquisition remediation cost, quantified for your deal team.

Integration planning

A strategic plan to integrate the acquired environment securely and mitigate risk after the deal closes.
