The SharePoint Blind Spot: How Legacy IGA Failed to Stop Volt Typhoon

Modern cybersecurity challenges have shifted from breaking into systems to exploiting legitimate access, with platforms like Microsoft SharePoint and Teams becoming key targets due to their complex permission structures and collaboration features. Attackers such as Volt Typhoon illustrate how identity governance, rather than endpoint security, is now critical, as they exploit legitimate credentials and operational complexities to remain undetected. Legacy Identity Governance and Administration (IGA) solutions fail to effectively manage the dynamic and sprawling permissions of cloud-based platforms, leading to potential security breaches that are exacerbated by the introduction of AI assistants like Microsoft's Copilot. These AI agents, capable of navigating permissions at machine speed, can inadvertently increase security risks by accessing and exposing sensitive data, highlighting the urgent need for modern identity security platforms that can provide comprehensive visibility and control over both human and non-human identities. This evolving threat landscape underscores the importance of identity governance as a core component of operational resilience, particularly in environments heavily reliant on cloud collaboration tools.
