Selling a French SME now involves rigorous digital checks that can impact price and timelines, as 40% of managers plan to sell within five years.
SME sales involve detailed checks
When selling a small or medium-sized enterprise, potential buyers conduct thorough checks on both financial accounts and computer systems before finalizing the sale. These checks can affect the offer price or delay the sale by several months. Buyers assess cybersecurity risks
The technical team hired by the buyer examines uncorrected vulnerabilities in the systems and verifies whether past incidents have been properly reported to the CNIL, France’s data protection authority. The team also calculates the potential cost of a data breach after the sale to adjust the offer. Many SMEs lack incident response plans
According to the 2025 Cybermalveillance.gouv.fr barometer, 16 percent of small and medium-sized enterprises with fewer than 250 employees experienced a security incident in the past year. Only one in four has a written incident response procedure. If a company lacks such a procedure, the buyer may detect it within the first hours of the check. Unreported breaches pose legal risks
The European data protection regulation requires companies to report a personal data breach to the CNIL within 72 hours of discovery. If a breach has not been reported, the buyer inherits the unfulfilled obligation and the risk of sanctions for a violation committed before the sale. A ransomware attack that has not been fully neutralized poses a second risk, as the attacker's access can be reused after the sale. Liability guarantees protect buyers
These situations directly affect the liability guarantee signed at the time of the sale, which protects the buyer if the reality of the business differs from what was declared before the signature. A portion of the price, generally between 5 and 10 percent, is held in an escrow account for the duration of this guarantee. If a very small business is sold without a formal liability guarantee, the buyer compensates for the absence of contractual recourse by applying a discount based on the flaws identified during the check. Security incidents affect valuation
According to the Cybermalveillance.gouv.fr barometer, 29 percent of companies affected by an incident experience business interruption, 22 percent experience data theft, and 11 percent suffer a direct financial loss. These consequences influence the price the buyer is willing to pay, whether the incidents are declared in advance or discovered after the fact. Good digital hygiene can speed up sales
A SME that demonstrates good digital hygiene can reverse the power balance and accelerate its sale. To clean up the security posture before the sale, it is recommended to document the information security policy before hiring a buyer. The ANSSI provides thirteen essential measures for small businesses and SMEs in its reference guide. Key security practices are essential
Testing offline backups at least once per quarter and documenting each test in writing is essential, as the buyer always requires written proof. Enabling strong authentication on email accounts and cloud access, isolating backups from the main network, and testing their restoration are also recommended. Training and tools help improve security
Continuous monitoring of systems and a patch management plan should be implemented. Staff should be trained with regular phishing simulation campaigns. The MalletteCyber Pro, launched in June 2026 for organizations with fewer than 250 employees, includes a practical booklet and a card game to sensitize teams without a dedicated budget. Eleven professional organizations, including CCI France and Medef, support this initiative. Preparation is crucial for a smooth sale
The kit is available under an open license and is ready to print directly. These checks take time and should be engaged in several months before contacting a buyer, not after receiving a first offer.
