Why departing employees create a major security gap

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
Connect HR and Entra ID/AD for real-time signaling.
Configure a leaver flow to revoke all linked apps and licenses.
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.
