Change Healthcare's ransomware attack threatened patient care and highlighted the cyber risks post-acquisition by UnitedHealthcare.
PinnacleOne outlines a framework to manage cyber risks when acquiring companies, focusing on technical, structural, and governance risks.
Mergers and acquisitions introduce risks like expanding attack surfaces, creating opportunities for lateral movement, and confusion over cybersecurity responsibilities.
Acquisition integration often lacks proper IT and security input, leading to unmanaged assets and increased cyber threats.
Companies should involve IT in due diligence, establish clear integration frameworks, and extend security governance across the entire enterprise post-acquisition.
Security must be a strategic priority in M&A processes to mitigate cyber risks and prevent potential breaches post-acquisition.
Companies need to rescale their security governance to match corporate growth and ensure comprehensive coverage of all newly acquired assets.
Cyber attackers exploit gaps in integration, making cybersecurity essential in every phase of the acquisition process to prevent vulnerabilities and intrusions.
Securing M&A integrations involves bringing IT into due diligence, establishing integration frameworks, and extending security governance to mitigate risks effectively.
