When Employees Leave, Does Your Data Go With Them?
It happens more often than most business owners realize. An employee gives two weeks’ notice — or sometimes no notice at all — and walks out the door. A week later, you discover their personal Dropbox still has copies of your client files. Their old email account is still active. The software licence you were paying for is tied to their personal Microsoft account. And nobody changed the Wi-Fi password.
This is not a hypothetical. It is one of the most common cybersecurity gaps we see when working with small and medium-sized businesses across Thunder Bay and Northern Ontario. And unlike a ransomware attack or a phishing email, it often goes completely unnoticed — until it becomes a problem.
Why Offboarding Is a Cybersecurity Issue
Most businesses think of employee offboarding as an HR task: collect the key fob, send the farewell email, update the org chart. The IT side gets treated as an afterthought, if it gets addressed at all.
But every departing employee represents a potential access point that needs to be closed. Consider what the average employee has access to after even six months on the job:
- Company email and calendar — which may contain sensitive client conversations, contracts, or financial discussions
- Cloud storage (Microsoft 365, Google Drive, Dropbox) — where business files may be saved to personal folders or synchronized to personal devices
- Line-of-business software — accounting platforms, CRM tools, project management apps, often accessed via shared credentials
- Remote access tools — VPNs or remote desktop connections that may still be active long after the employee leaves
- Social media and marketing accounts — where login credentials are rarely changed after a staff transition
When any of these remain accessible after someone leaves your organization, you have an open door. Whether the departure was friendly or not, that door needs to close the moment they walk out.
The Hidden Risk of “Friendly” Departures
Here is where businesses often get tripped up: they assume that because the employee left on good terms, there is no risk. Maybe it was a long-time employee you trust completely. Maybe it was a family friend.
Trust is not a security policy.
Even if a former employee has zero intention of misusing access, an active account sitting idle is a vulnerability. If their password is ever compromised — through a data breach, a phishing attack on their personal email, or password reuse — your business systems become an unintended target. The former employee did nothing wrong. But your business still pays the price.
What a Proper IT Offboarding Checklist Looks Like
A structured offboarding process protects your business without being punitive toward departing employees. At DVG Systems, we help businesses build and run exactly this kind of process. Here is what it covers:
Day of departure:
- Disable or transfer the employee’s email account (do not delete — preserve records)
- Revoke access to all cloud platforms: Microsoft 365, SharePoint, OneDrive, any SaaS tools
- Change shared passwords the employee had access to
- Revoke VPN and remote access credentials
- Remove the employee from any shared inboxes or distribution lists
Within 48 hours:
- Audit recent file access — look for bulk downloads or transfers in the days before departure
- Reassign software licences to active users or return them to the pool
- Review admin-level access — former employees should never retain elevated permissions
Within one week:
- Update any physical security codes or key fob access if applicable
- Confirm cloud storage has been audited and personal sync connections severed
- Document what was done for your records
The Cost of Getting This Wrong
The business impact of a poor offboarding process can range from minor inconvenience to serious legal exposure. Client data stored in a former employee’s personal account may constitute a privacy breach under Ontario’s privacy legislation. If a disgruntled former employee retains admin access to your systems, the damage potential is significant.
Beyond malicious scenarios, there is the everyday operational cost: paying for software seats that nobody is using, losing institutional knowledge because files were stored in personal folders, or spending hours tracking down account credentials that only one person knew.
For most small businesses, none of this is intentional. It is simply the result of growing without a structured IT process in place.
How DVG Systems Can Help
If you are not sure whether your business has a reliable offboarding process — or any process at all — that is worth knowing sooner rather than later. At DVG Systems, we work with businesses across Northern Ontario to build the kind of IT infrastructure that makes staff transitions smooth, secure, and documented.
That includes setting up centralized identity management so that access can be revoked from one place, implementing cloud policies that keep business data off personal devices, and running regular access audits so you know who has access to what.
