Cybersecurity in M&A

Embed cybersecurity considerations from the initial due diligence phase and carry them through to integration.

Securing the M&A Process


When looking to make an acquisition, assessing the target's cyber hygiene is as important as determining its financial health and market potential. Yet infosec leaders are often brought in late in the M&A lifecycle.

To truly harness the power of M&A in support of business expansion, it is imperative to embed cybersecurity considerations right from the initial due diligence phase and carry them seamlessly through to integration.

By integrating cybersecurity from the outset of an M&A endeavour, organisations can identify potential risks and vulnerabilities. This early insight allows for a comprehensive assessment of the cyber threat landscape, ensuring that any potential weaknesses in the acquiring and acquired companies' systems are addressed before they can compromise the deal or put the parties at risk.

Phases of the M&A Lifecycle

Enabling a CISO to participate in each M&A lifecycle phase helps to quicken and secure the transaction.

Pre-Signing: From identification to announcement


Pre-Closing: From announcement to legal Day 1


Post-Closing: From legal Day 1 to integration


Subsequently: Running as one improved entity
