When someone leaves your business—whether they’re retiring after a long career, moving on to a new opportunity, or even being shown the door—what do they take with them? A final paycheck? Their office plant? Maybe. But sometimes, they also walk away with something far more dangerous: the digital keys to your kingdom.
In the rush of daily operations, many businesses overlook the importance of digital inheritance. It’s not part of the exit paperwork, and it rarely makes it into a farewell email. But digital inheritance—the access, credentials, tools, and back-end knowledge held by past employees—is a growing cybersecurity risk. Combine that with aging systems and spotty offboarding practices, and you’ve got a perfect storm of vulnerability just waiting to be exploited.
The Invisible Footprints They Leave Behind
People leave behind more than memories. They leave digital footprints that can stick around long after their last day. Old logins. VPN credentials. Remote access tools synced to personal devices. The cloud-based apps they signed up for using their work email, but never offboarded. These remnants of digital access can remain hidden for months—or even years—until someone stumbles upon them, intentionally or not.
The trouble is, most businesses are unaware that these ghost accounts exist. Especially if an employee had admin privileges or worked across multiple systems, it’s easy for access points to go untracked. And if that employee ever held a grudge or simply left without a full debrief, the consequences can be painful.
Back in 2021, the Newfoundland and Labrador healthcare system experienced a massive cyber attack that exposed how digital vulnerabilities can linger in large institutions. While the exact cause of the breach wasn’t publicly confirmed, investigators noted that outdated systems and long-term gaps in oversight contributed to the severity of the incident. It was a wake-up call for organizations across Canada: your past can haunt your infrastructure.
So what’s the lesson here? Access doesn’t automatically expire with employment. Every unchecked login is an open invitation for a breach. The fix is simple but requires discipline—regular audits of all user accounts, especially those tied to administrative privileges, and automated alerts for any dormant access points.
The Hidden Risks in Legacy Systems
Every business has that one program they’ve used since 2003 that “still works just fine.” But legacy systems are rarely “just fine” when it comes to cybersecurity. Many of them were built long before modern access controls became the norm. They lack the ability to track who logs in, when, and from where. Some don’t even support multi-factor authentication.
It’s not unusual to find critical business functions still tied to systems that rely on a single, shared password. That password might be written on a sticky note under someone’s keyboard—or worse, stored in someone’s memory with no backup plan in place. These systems don’t just lag behind in performance—they lag behind in security.
Educational institutions in Canada have run into this problem repeatedly. In one high-profile case, several school boards continued using outdated platforms with known vulnerabilities, leaving student and staff data exposed. Despite warnings, patches were delayed, partly because the systems were deeply embedded in daily operations and partly because no one fully understood how they worked anymore.
Legacy systems may feel familiar, but their predictability can be a liability. If they can’t be monitored, logged, or updated easily, they create blind spots in your cybersecurity strategy. It’s not just about replacing them—it’s about recognizing when they’ve outlived their safe and useful life.
Modernizing those tools should be a priority, starting with any system that can’t enforce role-based access or support modern authentication methods. If a system can’t tell you who accessed it and when, it’s a problem waiting to happen.
Succession Gaps and Security Lapses
Sometimes, it’s not just the systems that are aging—it’s the staff who run them. And when they retire, your cybersecurity maturity may retire right along with them.
Many small and mid-sized organizations rely on one or two people to manage their IT environments. Over the years, these staff members collect knowledge like digital librarians—knowing which server needs to be rebooted monthly, which script needs to be run before updates, and where the “real” backups are stored. But too often, all of that wisdom lives in their heads, not in documentation.
When those individuals leave without transferring their knowledge, gaps open up fast. One Canadian municipality learned this the hard way in 2022 when its longtime IT lead resigned. The replacement team couldn’t access critical systems, documentation was missing, and former staff still had valid credentials for VPN and cloud portals. The town spent months untangling the mess, hiring outside consultants to figure out what had been lost.
This isn’t just an IT problem—it’s a business risk. If your systems can’t be operated, maintained, or secured by someone else, your organization is flying blind. That’s why digital succession planning matters just as much as financial or operational planning. Who will inherit the digital crown jewels when your tech lead walks out the door?
A strong strategy includes detailed documentation, clearly assigned digital asset ownership, and access protocols that don’t rely on tribal knowledge. Exit interviews should always include a technical offboarding component—and that means more than collecting a laptop.
The Human Element: Trust, Oversight, and Complacency
In many businesses, especially family-run or long-established companies, trust is a core value. But in cybersecurity, trust without oversight is a liability.
It’s not uncommon to hear, “Oh, Steve set that up years ago, but he left in 2019.” The assumption is that access was revoked and tools were reassigned. But unless someone physically reviewed every login, every credential, and every file-sharing connection Steve had, he may still have access.
Contractors, interns, temp staff, and even old vendors often fall into this same category. In some cases, former employees have returned months after leaving and found they still had full access to internal systems.
In 2023, a former employee of a Canadian retail chain exploited lingering access to sabotage digital infrastructure after a contentious departure. Their credentials hadn’t been removed, and they were able to quietly enter systems and cause disruption from afar. The damage was costly—not just in lost sales, but in reputation.
A simple fix? Create and follow a formal offboarding checklist. HR, IT, and department heads should collaborate to ensure that every possible access point—email, VPN, file shares, third-party tools, internal platforms—is shut down and reassigned when someone leaves.
Planning for a Safe Digital Succession
The heart of this issue is simple: no one stays forever. Every employee, vendor, and tool will eventually be replaced. The question is whether their departure will leave your business exposed or secure.
Security-focused succession planning means thinking about what comes next, before you’re forced to react. It means identifying who holds the keys today, and who will hold them tomorrow. It means having systems in place that allow you to revoke access at a moment’s notice—and to pass on responsibilities without starting from scratch.
After the Newfoundland and Labrador health breach, healthcare agencies across the country began reevaluating their frameworks. In Nova Scotia, some health authorities implemented succession and redundancy policies for key cybersecurity roles. These plans ensured that no one person had exclusive control and that system documentation was regularly updated, verified, and tested.
Your business doesn’t have to be in healthcare to learn the same lesson. You just need to start treating digital inheritance like the critical infrastructure it is.
Digital Inheritance Is a Cybersecurity Responsibility
Whether it’s a tenured employee retiring, a junior staffer moving on, or an old system still chugging along in the background, what remains after someone or something leaves can create serious risks.
Digital inheritance isn’t something we talk about enough, but it affects every business. The more access, control, and knowledge an individual has, the greater the responsibility your organization holds to transfer—or terminate—that control properly. Overlooking the digital remnants of your past is like locking every door in the building but leaving one window wide open.
This is about more than cleanup. It’s about planning forward. The moment someone joins your company, you should also be preparing for the day they leave—safely, cleanly, and without compromising everything they helped build.
