Small-business succession plans cover finances, legal exposure, and tax obligations. They almost never cover cybersecurity. That oversight can have serious consequences.
A few years ago, I spoke with a business owner in his seventies. He ran a small professional services firm with just a few employees, and he’d been his own IT department for the entire life of the company. Passwords, vendor accounts, firewall rules… he knew where everything was kept because he had put it there himself. There was a backup routine he ran every Friday afternoon from a desktop in his office.
He had no partner, no designated successor, and no written record of any of the systems he had built and maintained over two decades. If he had a stroke on a Tuesday, by Wednesday morning his employees would not be able to access their own files. Sensitive client data would be locked behind credentials that existed in one person’s memory and nowhere else.
But I couldn’t convince him he had a problem. He was healthy, he was sharp, and he had made it this far without incident. What did he need me for?
I think about him sometimes. Available data suggests he has a lot of company.
A Demographic Problem with a Cybersecurity Dimension
A 2025 U.S. Bank survey found that more than half of American small-business owners are now over the age of 55, but only 54 percent have a formal succession plan. Roughly a third said they plan to sell within the next twelve months. That same survey found that 62 percent of owners describe the succession process as overwhelming, which probably explains why so many of them put it off.
What caught my attention, though, was a different number in the same study: 85 percent of respondents identified fraud or cybersecurity threats as a top concern. In other words, the majority of small-business owners are, indeed, worried about cybersecurity. And they are also getting closer to an ownership transition. Unfortunately, virtually none of their transition planning connects those two facts.
This matters because the cybersecurity posture of a small business is not an abstraction. It is a collection of specific decisions, contracts, and compliance obligations. In a business with a hundred employees and a dedicated IT team, that knowledge is distributed. In a business with twelve or twenty employees, it often lives in one person’s head. A survey conducted for the National Association of Insurance Commissioners found that 71 percent of small businesses depend on one or two key individuals for organizational success. In my experience, for businesses under about fifty employees, “key individual” and “the person who handles IT” are often the same person. That person is frequently the owner.
The risk is that when that person steps away, for whatever reason, the cybersecurity posture of the business may not transition cleanly to the next owner. Instead, it can evaporate.
What Walks Out the Door
The risks follow predictable patterns.
The most immediate is the credential problem. In a startling number of small and midsize businesses, critical passwords and access credentials live in a personal password manager the company doesn’t control or on a sticky note in an office drawer. When that person departs, it’s all too easy for the keys to the kingdom to go with them. Even in firms where multiple people have system access, transitions create confusion. Departing owners retain credentials to platforms long after they have stepped away. Incoming owners inherit admin privileges to environments they have never audited and might not fully understand.
Then there are the vendor / contractual issues. Most SMBs maintain relationships with cloud providers, SaaS platforms, payment processors, and IT contractors that carry security obligations embedded in the contract language. In healthcare, that might be Business Associate Agreements under HIPAA. Any organization handling payment card data probably has PCI DSS obligations. And so on. If the outgoing owner signed these agreements and the successor doesn’t know they exist, compliance gaps begin accumulating on day one. The same applies to cyber insurance: if the policy includes technical attestations about specific security controls, the new owner is now legally bound by representations they never reviewed.
Third, undocumented security decisions compound the risk over time. Every business has choices built into its infrastructure that nobody remembers making. Why is this port open on the firewall? Who configured the VPN, and when was the last time someone reviewed who has access to it? Is there a service account with global permissions that has not been touched in three years? The person who made those decisions, or who at least understood the reasoning behind them, is walking out the door.
This is more than just a security risk, it’s a valuation risk. M&A advisors have long recognized that key-person dependency depresses the price a buyer is willing to pay. Research on publicly traded companies puts the discount at roughly ten percent, but for small, privately held firms the effect can be much larger. In extreme cases, a sole proprietorship whose operational knowledge lives entirely in the owner’s head may not have much transferable intangible value at all. When “operational knowledge” includes the entire cybersecurity infrastructure of the business, that discount gets very real, very fast.
Adding Cybersecurity to Your Succession Plan
None of this requires a six-figure engagement or a months-long security overhaul. What it requires is treating cybersecurity as a line item in the transition plan, alongside financial due diligence, legal review, and tax obligations. For a business owner preparing for any kind of ownership change—whether it’s a sale, a retirement, or simply bringing on a partner—here is what I would tell them to address.
Create a security asset inventory. Before any ownership change, someone needs to document, in writing, the following:
- every system and platform the business uses
- who has access to each and at what privilege level
- where credentials are stored and in what format
- what vendor contracts carry security or compliance provisions
- what regulatory frameworks apply to the company’s data
- what the cyber insurance policy actually requires
Think of this as the cybersecurity equivalent of a balance sheet. Most small businesses have never created one. It does not need to be elaborate, but it does need to exist, and it needs to be accurate, and it cannot live in a single person’s memory.
Conduct a security assessment before the transition, not after. The time to discover that the backup system has not been tested in two years, or that former employees still have active accounts, or that the firewall rules were last reviewed during the Obama administration, is before the handover. Once the transition is complete, pre-existing problems become the new owner’s problems. A baseline assessment using a framework like NIST CSF gives both parties a shared, objective picture of the company’s security posture, and it provides the incoming owner with a roadmap for what to fix first.
Plan for credential transfer with the same rigor you would bring to handing over the keys to a building. Identify every system, platform, and account. Reset or transfer administrative credentials to a business-controlled password manager. Disable the departing owner’s access on a defined schedule. And document the process so there is a clear chain of custody. If a breach occurs six months after the transition and the forensic investigation reveals that the former owner’s credentials were never revoked, that is a finding that can affect insurance claims, regulatory responses, and legal liability.
Brief the successor on compliance and contractual obligations. If the business handles protected health information, stores customer payment card data, or operates under a state or federal data protection framework, the incoming party needs to understand those obligations before they take ownership. The same goes for any vendor agreement that includes security requirements and any cyber insurance policy that includes technical attestations. Six months later, when an auditor calls or an insurer asks for documentation, is too late to start learning about what you inherited.
Get an outside perspective. Admittedly, this is the recommendation where I have an obvious interest, so take it for what it is. But the person who built the systems over a period of years is rarely the best judge of where the vulnerabilities are. The old saying goes, “familiarity breeds contempt,” and I don’t know if that’s true, but I do know that familiarity breeds blind spots. Things you’ve lived with for a long time start to look normal, even when they should not. An independent review conducted during the transition period will catch risks that neither the outgoing nor the incoming party would have spotted on their own.
The Real Cost of Postponing
Retirement, sale, partnership changes, a founder stepping back from daily operations: these transitions generate meticulous financial and legal planning. In the aforementioned survey from U.S. Bank, 62 percent of business owners described the process as overwhelming, so it’s no surprise that cybersecurity, which many owners already find intimidating on its own, gets pushed to the bottom of the list. But a transition is the single highest-risk moment in the life of a business’s cybersecurity posture. Institutional knowledge is leaving. New people are arriving with incomplete information. The gap between what someone assumes is in place and what is actually in place is at its widest.
That is a significant oversight, because in 2026, the cybersecurity posture of a small business effectively is the business. Client data, payment systems, regulatory obligations, access controls, vendor agreements with embedded security provisions, insurance policies with technical attestations: all of it travels with the company when ownership changes, whether the incoming party knows it or not.
The owner I met a few years ago is, as far as I know, still running his firm. He is also still the only person alive who knows how any of it works. I hope nothing happens to him on a Tuesday.
But hope is not a cybersecurity strategy. Let’s talk about yours.
