What is Cybersecurity Due Diligence?

Before you acquire a company, invest in a startup, or partner with a vendor, you need to know what cyber skeletons are hiding in the closet. Our Cybersecurity Due Diligence service provides a thorough, independent assessment of a target organization's security posture, data protection practices, and regulatory compliance. We've performed due diligence for private equity firms, venture capital funds, and corporate development teams across deals ranging from $5M to $500M+. Our reports give you the clarity to negotiate better terms, budget for remediation, or walk away from a bad deal. Phase 1 can be conducted without the target's knowledge - using publicly available information, threat intelligence, and external scanning. This is ideal for early-stage confidential screening. Subsequent phases include internal review and comprehensive technical assessment. Timelines: External-only reviews take 5-7 business days. Comprehensive internal assessments take 2-4 weeks. Complex multi-entity evaluations take 4-8 weeks. Expedited options are available for compressed deal timelines. Critical findings receive immediate communication to deal teams - we don't hold significant discoveries for the final report. We help quantify severity, potential impact, and remediation complexity for informed decision-making. Regulatory context: SEC disclosure rules require material cyber risk reporting. GDPR mandates data protection impact assessments. HIPAA holds acquirers responsible for PHI practices. FTC Safeguards Rule requires financial institutions to assess acquired entities. NIS 2 mandates cybersecurity risk management for critical sectors.
