M&A cyber due diligence

Connect with us

Businesses undergoing mergers and acquisitions must complete rigorous due diligence to uncover and remediate concerns about the security posture of their merger/acquisition targets. They must also estimate post-deal security investment requirements.

Evaluate risk throughout the merger or acquisition process

Our proven approach

During the due diligence phase, we provide a rapid cybersecurity risk assessment that rates the maturity of the organization’s risk management, security organization and technology, third-party risk, cyber breach preparation, and more. The duration of the assessment is flexible based on the situation – but typically involves a two-to-four-week engagement that evaluates the acquisition’s IT environment and cyber risk levels across critical security dimensions.

The service is the ideal companion to our external penetration testing service, a best-practice strategy in which you’ll gain an independent view of what the acquisition target looks like to an attacker.


We provide design and implementation support to integrate or extract an organization while ensuring appropriate security controls and governance processes are in place.

  • Our industry-leading practitioners can design required capabilities to manage risk, create new solutions, and establish new organizational approaches and governance models.
  • We partner with you, as needed, throughout the implementation process with advisory services that can help with architecture design, vendor/product selection, and general implementation support.
