5 Ways Cybersecurity Reduces Exit Valuations

When a private equity firm prepares to realise an investment, attention turns to the headline metrics: revenue growth, EBITDA margins, market position and management strength. Cybersecurity rarely makes that list. Yet by the time a portfolio company reaches sale, unaddressed cyber weaknesses tend to resurface at the wrong possible moment, dragging down the very number that matters most to your fund and its LPs.

Cyber risk is no longer an abstract IT concern. It is a financial liability that buyers actively price into their offers. A sophisticated buyer, properly advised, treats unresolved security gaps as grounds to discount, delay or renegotiate -  a measurable hit to enterprise value at exit. These are the five mechanisms most frequently used, each one pointing to something deal and value creation teams can do to protect the return.

Undisclosed breaches surface during due diligence

Nothing erodes buyer confidence faster than the an incident the vendor failed to identify or disclose. A buyer’s advisers will scrutinise the target's external attack surface, examine historic incidents and search the dark web for compromised credentials and leaked data. When they find evidence of an unreported breach, the damage runs deeper than the breach itself: the buyer begins to question the reliability of every other representation made during the process, and reprices to reflect remediation costs, regulatory exposure and reputational consequences. Genuine exit readiness means there is nothing left to find; everything is disclosed, along with mitigations. Continuous portfolio monitoring throughout the hold period ensures that you know exactly what a buyer's advisers will see, allowing you to control the narrative rather than react to it.

Governance gaps signal a poorly run asset 

Buyers assess not only whether a company has been breached, but whether it can prevent, detect and respond to an incident. No clear security governance, no incident response plan and no evidence of board-level oversight signals something broader: a business that has not been managed to the standard a buyer expects. Cyber governance is a good a proxy for operational maturity. An organisation that demonstrates alignment with a recognised standards such as NIST, and can show the board has actively overseen cyber risk, presents as a well-run, exit-ready asset. Strong governance is not built in the final quarter before a sale. It is the product of sustained attention across the hold period, and among the most reliable ways to defend enterprise value at exit.

Regulatory exposure follows the fund past completion 

Frameworks such as NIS2, DORA and GDPR impose real obligations, and the penalties for non-compliance are significant. A portfolio company falling short of its regulatory requirements carries a liability that can lead a buyer to renegotiate or walk. The exposure crystallises around the representations and warranties given at exit: if a seller warrants compliance and that warranty later proves false, the consequences follow the fund beyond completion. Buyers know this and price the uncertainty accordingly – demanding  indemnities, retaining consideration in escrow, or simply cutting their offer. Establishing exit readiness means identifying and closing regulatory gaps well ahead of a sale, protecting the fund from post-exit claims.

Infrastructure weaknesses are priced as future cost

Where weaknesses persist - unpatched infrastructure, poor access controls, an unmanaged supply chain - the buyer sees latent risk that will need capital to fix. That cost is deducted from the final offer, and the value creation work invested elsewhere is diminished by a liability sitting in plain sight. Treated as a component of portfolio company valuation rather than a burden, cybersecurity turns from a valuation limiter into a demonstrable enhancement. Addressed early, these are the exact weaknesses that a focus on exit readiness resolves long before a buyer can price them in.

Last-minute remediation damages negotiating leverage

Deals lose value when they lose momentum. Cyber issues discovered late force the vendor into reactive remediation under time pressure -  the worst possible time to address a security gap: costs are higher, options are narrower, and the buyer holds the leverage. A live incident surfacing mid-process can derail a transaction entirely. A portfolio company that has been continuously monitored and progressively reinforced arrives at sale exit ready, with no scramble and a strong negotiating position.

Turning cyber from liability into value

For deal and value creation teams, the opportunity is clear. Cyber posture is one of the few areas of exit value still routinely left on the table – quantify it, evidence it, and it becomes a lever rather than a liability. Thomas Murray works with value creation teams to do exactly that: transforming cybersecurity from a cost centre into a driver of enterprise value across the portfolio, and delivering an asset that is genuinely exit ready - with no surprises waiting in due diligence and a value creation history that holds up to scrutiny.
