Pre-Deal Monitoring
A typical mid-cap PE fund might be tracking up to 100 potential acquisition targets at once. Monitoring them early allows you to track a company’s long-term cyber security trends, and to identify critical issues which could impact a deal (e.g. database compromise). Thomas Murray’s Orbit Security platform provides non-intrusive, continuous monitoring, without alerting the target company.
- External Attack Surface Monitoring
- Dark and Deep Web Monitoring
M&A Due Diligence
Deal teams often run 7–10 workstreams at once, with cyber typically left until late in the process. Our workflows deliver rapid, effective cyber due diligence to uncover risks that could impact valuation, warranties, or deal structure. Through threat modelling and organisational value analysis, we provide fast assessments with actionable recommendations. Thomas Murray integrates seamlessly into your broader M&A due diligence, covering:
- Supporting IP
- Regulatory, Governance & Compliance
- Data Protection
- Information Security
- Commercial Due Diligence


Business as Usual: Value Creation across the Portfolio
Thomas Murray partners with Operations Partners and Value Creation teams to continuously monitor cyber threats across their portfolios, as well as engaging with PortCos to identify and mitigate specific risks.
- Continuous Monitoring (external)
- Cyber Risk Assessment (internal)
- PortCo Engagement (improving)
- 24/7 Incident Response (responding)
First and Final 100 Days
Whether you are making or realising an investment, during the first 100 days after the announcement of an acquisition you should be hyper-alert to the risk of cyber attack. Sophisticated threat actors can exploit weaknesses exposed during an M&A process, including sensitive data exchange during due diligence, integrating IT systems, and disruption to workflows and employees.
- Preparing PortCo for Exit
- Continuous breach monitoring

Why cyber matters: the Private Equity blind spot
Cyber incidents are value events
Ransomware, breaches and data exposure can trigger sudden value destruction - just like revenue loss or regulatory fines. A breach pre-exit can delay or derail a deal, and a cyber incident in a portfolio company can be a huge distraction and reputational issue for the fund.
Cyber risk is M&A risk
LPs and Regulators are watching. Institutional investors are increasingly asking investors about ESG and cyber governance as part of ODD, and regulations are starting to name private equity explicitly.
Cyber resilience = fiduciary responsibility
Portfolio companies often share vendors, cloud infrastructure and managed services; interconnected supply chains multiply risk, with a breach in one company spreading across shared environments.
Cyber intelligence is a strategic advantage
Firms that monitor cyber posture across their portfolio can act early, avoid loss and increase exit multiples. Cyber due diligence can also add leverage during acquisitions, especially in tech and regulated sectors.
Cyber insurance is not a strategy
Cyber insurance markets have been softening, but high-profile cases like M&S show that insurance is not an adequate substitute for resilience.
