When an employee leaves your organization, the usual process involves handing over responsibilities, returning company equipment and completing any outstanding administrative requirements. But there is another important step that businesses sometimes overlook: ensuring that the person no longer has access to company systems and information.
An employee may have left months ago, yet their email account, cloud storage permissions, VPN access or credentials for a business application could still be active. In some cases, nobody notices because the account is no longer used regularly. In others, access remains because the organization has no clear process for removing it.
This creates a security risk that has little to do with viruses or malicious software. Your systems may have antivirus, firewalls and other protective measures, but those tools cannot necessarily prevent someone from accessing business information through an account that is still authorized.
The question is simple: when someone leaves your business, how certain are you that their access leaves with them?
Why Former Employees May Still Have Access
Employee access tends to grow over time. Someone who joins as an administrative officer may eventually receive permissions to shared folders, customer records, financial documents, project management tools and other business applications. As their responsibilities change, new access is granted, but old permissions are not always removed.
When the employee eventually leaves, the organization may disable their primary email account without realizing that several other accounts and permissions remain active.
This is especially common in businesses that use multiple cloud services, shared passwords, third-party applications and systems managed by different departments. Without a central record of who can access what, removing every permission becomes difficult.
The problem is not always deliberate. Access can remain simply because nobody knows it exists.
1. Old Accounts Can Become an Entry Point
An inactive account may seem harmless, particularly when the former employee has no intention of using it. However, an account that remains active can still be compromised.
If its password was reused elsewhere or exposed in a data breach, someone may attempt to use those credentials to access company systems. Because the account is legitimate, the activity may not immediately appear suspicious.
This is one reason cybersecurity involves more than installing security software. Organizations also need to know which accounts exist, who owns them and whether they are still required.
Regular account reviews can help businesses identify unnecessary access before it becomes a problem.
2. Shared Passwords Make Access Difficult to Control
Many businesses share credentials for certain applications, social media accounts, software platforms or administrative systems. While this may appear convenient, it creates difficulties when employees leave.
If several people know the same password, removing one employee’s individual account may not prevent them from accessing the shared system. The business may need to change the password and review any connected sessions, recovery options or authentication methods.
A better approach is to provide individual accounts wherever possible, with permissions appropriate to each employee’s responsibilities. This makes it easier to manage access, identify activity and remove permissions when someone leaves.
Where shared credentials cannot be avoided, businesses should have a clear procedure for updating them during employee offboarding.
3. Cloud Applications Can Be Easily Forgotten
Company access no longer exists only within the office network. Employees may use cloud storage, accounting platforms, customer relationship management systems, communication tools and project management applications from different locations and devices.
An employee who leaves the organization may lose access to their company email but retain access to a shared cloud folder or an application that uses separate login credentials.
Some systems may also allow users to remain signed in across multiple devices until their sessions are revoked.
This is why businesses need to consider the complete technology environment during offboarding, rather than focusing only on the most visible accounts.
4. Sensitive Business Information May Remain Exposed
Employees need access to information to perform their jobs, but that access should reflect their current responsibilities.
A former employee may previously have worked with customer records, contracts, financial information, internal documents or confidential project files. If their permissions remain active, the organization may continue exposing information that the person no longer has a business reason to access.
The potential consequences depend on the type of information involved. For some organizations, the concern may be confidential business plans. For others, it may involve customer information, financial records or documents belonging to clients.
Removing unnecessary access is therefore not just an IT housekeeping task. It is part of protecting the information entrusted to the business.
5. Remote Access Needs Particular Attention
Remote working has made it easier for employees to connect to company resources outside the office. VPNs, remote desktop services and cloud-based applications allow staff to work from home, travel or access systems from different locations.
These capabilities support productivity, but they also make access management more important.
When an employee leaves, organizations should review remote access permissions alongside their other accounts. A person who no longer has a company laptop may still have valid credentials for a remote service.
Businesses should also consider whether personal devices were used to access company information and whether organizational data or active sessions remain on those devices. The appropriate steps will depend on the systems involved and the organization’s device management arrangements.
What Should Happen When an Employee Leaves?
A proper employee offboarding process should involve both the human resources and IT teams. Once an employee’s departure is confirmed, the organization should identify the systems they can access and determine when those permissions should be removed.
The process may include disabling individual accounts, revoking active sessions, removing VPN and remote access permissions, reviewing shared credentials, recovering company devices and transferring ownership of important files or business resources.
Timing matters. Access removal should align with the employee’s departure arrangements and the organization’s security requirements, rather than being left for an unspecified date after their last working day.
Businesses should also keep appropriate records of completed access changes so that they can verify the process rather than assume it happened.
Don’t Forget Employees Who Change Roles
Former employees are not the only people who may retain unnecessary access.
An employee who moves from finance to operations, for example, may continue to hold permissions from their previous role while receiving new ones. Over time, this can create accounts with access to more information than the person needs.
Organizations should therefore review permissions when employees change departments or responsibilities, not only when they leave.
This follows an important cybersecurity principle known as least privilege: people should have the access necessary to perform their work, without retaining permissions they no longer require.
Applying this principle helps reduce unnecessary exposure while making access easier to manage.
How Can Your Business Find Out Who Still Has Access?
The first step is to understand where employee accounts and permissions exist.
Businesses can begin by reviewing their email systems, cloud applications, shared storage, servers, network access and other important platforms. They should identify inactive accounts, unnecessary permissions and access that cannot be clearly linked to a current employee or approved business requirement.
However, a complete review may require looking beyond account lists. Shared credentials, third-party services, remote access configurations and inconsistent administrative practices can make the situation more complicated.
A cybersecurity assessment can help organizations examine these areas, identify weaknesses in access management and determine what needs to improve.
The goal is not simply to remove old accounts. It is to establish a reliable process that prevents the same problem from recurring.
How Support Systems Can Help
Support Systems provides cybersecurity services and technology consulting to help organizations understand and strengthen the security of their IT environments.
Through a cybersecurity assessment, businesses can examine potential weaknesses in areas such as user access, system configurations, network security and existing security practices. The findings can help organizations identify where controls need improvement and develop a more structured approach to protecting business systems and information.
Support Systems also provides IT infrastructure solutions and technical support, helping businesses maintain technology environments that remain manageable as employees, applications and operational requirements change.
For organizations that have grown without regularly reviewing access permissions, assessing the current environment can be an important starting point.
Does Access Really End When Employment Ends?
An employee leaving your business should not create uncertainty about who can still access its information.
Yet without a structured offboarding process, old accounts, shared passwords and forgotten permissions can remain active long after someone has left. These weaknesses may be easy to overlook because they do not always cause an immediate disruption.
Effective cybersecurity requires businesses to pay attention to the people who can access their systems, not just the threats their security software can detect.
If your organization cannot confidently account for every person who has access to its important systems, it may be time to review those permissions.
