Why departing employees create a major security gap

5 minutesmin read

An employee leaves, but their Microsoft 365 and SaaS accounts remain active. It might seem harmless, but it opens the door to data breaches and compliance violations.

🔓 What Can Go Wrong

  • Unauthorized access – Former employees can still reach email, Teams, CRM, or customer data.

  • Shadow IT – Forgotten accounts can be exploited for illegal access or phishing attacks.

  • Compliance violations – GDPR and ISO 27001 require immediate revocation of access when employment ends.

  • Cost leakage – Licenses and cloud services continue to run, adding unnecessary subscription costs.

How It Happens

Manual processes, shared mailboxes, multiple SaaS apps, and a lack of centralized identity management make it easy to overlook accounts. Growing organizations lose track quickly.

🛡️ The Solution: Automated Offboarding

  • HR as the source of truth – The HR system holds the official termination date.

  • Automatic de-provisioning – Joinly connects HR to Entra ID/AD and disables accounts as soon as an employee leaves.

  • Reporting & logging – Provides evidence for auditors and internal controls.

✅ Implementation with Joinly

  1. Connect HR and Entra ID/AD for real-time signaling.

  2. Configure a leaver flow to revoke all linked apps and licenses.

  3. Review regularly with reports to ensure no “orphan accounts” remain.

Conclusion

Failing to offboard is not a minor oversight but a serious security and compliance threat.
Automated offboarding with Joinly ensures former employees lose access, meets regulatory requirements, and cuts unnecessary license costs.
