When Companies Merge, So Do Their Cyber Threats
HelpNet Security, Wednesday, April 16th, 2025
For CISOs, mergers and acquisitions (M&A) bring both potential and risk. These deals can drive growth, but they also open the door to serious cybersecurity threats that may derail the transaction. Strong due diligence, smart risk planning, and a shared security mindset can help keep deals on track and protect the business.
Key cybersecurity risks in M&A
1. Inherited vulnerabilities: Acquiring a company means inheriting its existing cybersecurity weaknesses. If the target company has unresolved security issues, these become the acquirer's responsibility. For instance, undisclosed data breaches or outdated systems can pose immediate threats post-acquisition.
2. Data integration challenges: Merging IT systems can lead to data silos and integration difficulties. Inconsistent data protection measures between the two entities can expose sensitive information during and after the integration process.
