M&A Cyber Due Diligence
Cybersecurity insights into acquisition targets throughout the deal lifecycle.
Cyber Due Diligence for M&A:
Uncover Risks, Secure Deals, Protect Returns
Cyber due diligence is the process of assessing an organisation’s cybersecurity posture, vulnerabilities, and potential risks before a merger or acquisition. It identifies hidden threats, compliance gaps, and exposure to cyber incidents that could impact valuation, integration, and long-term business continuity. By conducting a thorough review of security controls, data protection measures, and historical breaches, cyber due diligence ensures investors and acquirers make informed decisions, mitigating financial and reputational risks before closing the deal.
Why engage in cyber due diligence?
Failing to conduct cyber due diligence can expose your investment to hidden security risks, regulatory penalties, and financial losses—protect your deal by identifying and mitigating threats before they become costly liabilities.

or operational disruption

Support Legal & Operational DD

How we help Private Equity firms:
Our approach to cyber due diligence is thorough, risk-focused, and tailored to M&A transactions. We assess a target company’s security posture, compliance standing, and potential threats, providing clear, actionable insights that help investors mitigate risk and protect deal value.
We carry out in-depth analysis of the target organisation by leveraging OSINT and Dark Web data sources. We are looking to uncover any information that might impact the value of the business or the security of the investment.
During the deal execution phase, we aim to get more "hands-on" and can deliver our Cyber Risk Assessment and Cyber Health Check, which both provide much deeper insight into the cybersecurity posture of the target business.
To help our clients manage the Post-Deal Integration phase. we carry out Threat Modelling to analyse the result of the integration and where existing and new security gaps may be. Our vCISO service allows us to place a manageable wrapper around any follow-up services that might be required.
Our M&A Cyber Due Diligence Process

Scoping is where we determine what is required of us from a cyber due diligence perspective and how deep we need to go with our cyber due diligence checks.
3. Execution
With a scope agreed, we can get to work executing out portfolio of cyber services, from light-touch cyber due diligence right through way through to a cyber risk assessment and a full cyber health-check.
4. Review
Once our services have ben successfully delivered, we review the outcomes and results to ensure we have met your expectations and continue to look for areas of improvement.
Frequently Asked Questions
We work with Private Equity firms on deals of all sizes, although the majority of our client base tends to be the lower-middle to middle market.
We start off with a discovery call to understand the industries your firm operates in and the typical deal size. We can then begin to make recommendations on what's appropriate and proportionate from a cyber due diligence perspective.
The typical due diligence services (operational, financial and legal) all obviously play a core role in due diligence. Cyber due diligence is still a largely under utilised type of due diligence, which most M&A deals can benefit from greatly. Our cyber due diligence service works alongside the other due diligence services.
Cyber due diligence helps identify hidden security risks, compliance gaps, and potential liabilities that could impact valuation, deal success, and post-acquisition integration. Without it, investors risk inheriting costly breaches, regulatory fines, and operational disruptions.
Cyber due diligence should be performed as early as possible in the pre-deal phase to uncover risks before negotiations progress. However, it can also be conducted post-deal to mitigate inherited vulnerabilities and strengthen security integration.
