An employee leaves your company. You collect their keys, wish them well, and move on. But what if they still have access to your business long after their last day?
The Employee Who Never Really Left
Imagine this scenario:
It's Monday morning, and the owner of a small business receives a call from a longtime customer.
"Why did someone from your company download our confidential information last night?"
Confused, the owner begins investigating. The employee responsible for that customer account left the company three months ago.
Their office keys were returned. Their final paycheck was issued. Their desk was cleaned out.
But nobody told the company's IT provider that the employee had left.
As a result, the former employee's email account was still active. They could still access company files, customer information, and shared documents from their personal laptop.
Whether the former employee accessed the information intentionally or someone else gained access to their old account, the damage was already done.
Now the business owner is facing an angry customer, a potential data breach, and questions about how this could have happened.
The worst part?
It was entirely preventable.
This story is fictional, but the security risks it illustrates are very real.
When an Employee Leaves, Their Digital Access Doesn't Automatically Leave With Them
Most business owners understand the importance of collecting company property when an employee leaves.
You ask for their office keys, laptop, company credit card, and perhaps their building access badge.
But what about their digital keys?
During their employment, staff members may be given access to:
- Company email and calendars
- Customer records and confidential information
- Shared files and documents
- Accounting and financial systems
- Business applications and online subscriptions
- Company information accessible from personal phones and computers
- Passwords for shared company accounts
Unless someone takes deliberate steps to remove that access, a former employee may continue to have access to sensitive business information for weeks, months, or even years after leaving.
And unfortunately, this happens more often than business owners realize.
Five Risks of Failing to Properly Offboard Employees
1. Former Employees May Still Access Confidential Information
Not every employee leaves on good terms.
A disgruntled former employee who retains access to company systems could potentially download customer lists, pricing information, financial records, or other confidential documents.
Even employees who leave amicably should no longer have access to information they don't need.
Once someone is no longer employed by your business, their access should end.
2. An Unused Email Account Can Become a Security Risk
Imagine a former employee's email account remains active six months after their departure.
Nobody is monitoring it. Nobody is using it.
But cybercriminals don't care whether the employee still works for you.
If someone obtains that account's login information, they may be able to read confidential emails, impersonate your company, or send fraudulent messages to customers and vendors.
Worse, because the account belongs to a former employee, suspicious activity may go unnoticed.
3. Customer Relationships and Your Reputation Could Be Damaged
Your customers trust you to protect the information they share with your business.
If a former employee accesses customer records after leaving, that trust could be compromised.
Depending on the information involved, your company could face customer complaints, financial losses, legal expenses, or reporting obligations.
For businesses that handle medical, financial, or other sensitive information, the consequences can be particularly serious.
4. Your Business May Be Paying for Employees Who No Longer Work There
Here's a risk that isn't always about cybersecurity: unnecessary expenses.
Many businesses pay monthly or annually for employee email accounts, Microsoft 365 licenses, and other software subscriptions.
If your IT provider doesn't know an employee has left, those subscriptions may continue.
Over time, paying for accounts that are no longer needed can add up.
Some annual software commitments cannot be reduced until renewal, making timely communication with your IT provider even more important.
5. Former Employees Could Accidentally Cause Problems
Not every security incident involves someone with bad intentions.
Consider a former employee who still has company email connected to their personal phone.
They might accidentally open confidential information, respond to a customer who doesn't realize they've left, or continue accessing shared company documents.
Their personal device could also be lost, stolen, or compromised.
Even well-intentioned former employees shouldn't have access to your business after their employment ends.
"But We Changed Their Password. Isn't That Enough?"
Not necessarily.
Changing an employee's email password is a good start, but it may not address every way they access your business.
For example, they may still have access to shared documents, business applications, or accounts that use a separate login.
They may also have company information saved on personal devices.
Proper employee offboarding involves reviewing all the ways that person accessed company information and making sure those connections are appropriately removed.
Think of it this way: Changing the front door lock doesn't help if someone still has a key to the back door.
What Should You Do When an Employee Leaves?
The good news is that protecting your business doesn't have to be complicated.
The most important step is communication.
Notify your IT provider as soon as you know an employee is leaving.
Ideally, your IT provider should be informed before the employee's final day so access can be removed at the appropriate time.
A proper offboarding process should include:
- Disabling access: Make sure the former employee can no longer sign in to company email, files, and business systems.
- Protecting company information: Preserve important emails, documents, and customer records that the business needs to retain.
- Reviewing shared passwords: Change passwords for shared accounts the employee could access.
- Securing company equipment: Collect company-owned computers, phones, and other devices, and address company information on personal devices where appropriate.
- Reviewing software subscriptions: Identify licenses that may be reassigned or discontinued when permitted by the subscription terms.
- Ensuring business continuity: Make arrangements so customers, vendors, and coworkers can still reach the appropriate person and important business information isn't lost.
These steps help protect your business while making the employee's departure smoother for everyone involved.
Don't Wait Until an Employee's Last Day
Here's something many business owners don't consider:
Employee offboarding should be part of your company's standard departure process, just like collecting keys and processing a final paycheck.
Whether someone resigns, retires, is terminated, or simply finishes a temporary assignment, their digital access needs to be addressed.
For planned departures, notifying your IT provider several days in advance allows time to prepare.
For unexpected or involuntary terminations, access may need to be removed immediately, coordinated with the employee's departure.
And if you suddenly realize that someone left your company months ago and you never notified your IT provider?
Tell them now. It's better to address the oversight today than discover a problem tomorrow.
Your IT Provider Can't Protect What They Don't Know About
At Computer Services Unlimited (CSU), we work hard to protect our clients from cybersecurity threats, unauthorized access, and data loss.
But there's one thing we can't always know unless you tell us:
When someone no longer works for your company.
We don't automatically receive notifications when your employees resign, retire, or are terminated.
If we're not informed, we may have no reason to know that their accounts should be disabled or their access removed.
That's why we encourage every client to make employee offboarding a standard part of their business procedures.
A quick notification to CSU can help prevent a much bigger problem down the road.
One Simple Question Every Business Owner Should Ask
"Do any former employees still have access to my business?"
If you're not sure, now is a good time to find out.
CSU can help review existing user accounts, identify access that may no longer be appropriate, and establish a straightforward employee offboarding process.
Because protecting your business isn't just about keeping hackers out.
It's also about making sure the people who have left your company have truly left your systems.
