When an employee leaves a business, it's easy to focus on collecting their equipment, updating records and making sure their responsibilities are handed over. However, one important task can sometimes be overlooked, removing their access to business IT systems.

Former employees, contractors and even previous suppliers may still have active accounts long after they've stopped working with your business. These forgotten accounts can create security weaknesses, leaving sensitive information and important systems exposed to unnecessary risks.

Why Are Forgotten Accounts a Security Risk?

Every active user account can potentially provide access to business information, applications and systems. If an account is no longer needed but remains active, it creates another opportunity for someone to gain unauthorised access.

For example, a former employee might still have access to their old email account, Microsoft 365 applications or shared company files. If their login details are compromised, a cybercriminal could potentially use that account to access sensitive information without immediately raising suspicion.

Unused accounts can be particularly difficult to monitor because they're unlikely to generate regular activity. This means suspicious access could go unnoticed for longer than it would with an account that's actively used.

Don't Forget Contractors and External Suppliers

It's not just former employees who can leave behind unnecessary access. Contractors, temporary workers and external suppliers may also have been given accounts to access specific systems or information.

These accounts are often created to support a particular project or provide temporary assistance. However, once the work is completed, access isn't always removed.

Over time, businesses can accumulate accounts belonging to people who no longer need access. If these accounts aren't reviewed regularly, they can create unnecessary security risks and make it harder to keep track of who can access company information.

The Importance of Regular Access Reviews

Reviewing user accounts regularly helps businesses maintain control over who can access their systems and data. It's worth checking all active accounts and confirming that each person still requires the access they've been given.

Some useful steps include:

• Remove former employees: Make sure accounts belonging to employees who have left are disabled or removed appropriately.
• Review external access: Check accounts belonging to contractors, suppliers and temporary workers to confirm they're still required.
• Check permissions: Make sure employees only have access to the information and systems they need to perform their roles.
• Identify inactive accounts: Investigate accounts that haven't been used for extended periods and establish whether they're still necessary.
• Review administrator access: Limit privileged accounts to authorised individuals who genuinely need them.

It's also important to have a clear offboarding process so that removing access becomes a standard part of an employee's departure rather than something that relies on someone remembering later.

Keep Your Business Accounts Secure

Forgotten user accounts might seem like a minor administrative issue, but they can create significant security weaknesses if left unmanaged. Regular access reviews and clear procedures for managing employees and external users can help reduce unnecessary exposure and protect your business information.
