Webinar: How to Govern AI Agents, Reduce Excessive Access, and Control Shadow AI

The Hacker News

AI agents are increasingly being deployed in business environments without adequate security oversight, posing significant risks. These agents are capable of accessing applications, managing data, and interacting with APIs, often without the same safeguards that protect human users. A report from Okta found that just 47% of Chief Information Security Officers (CISOs) are confident in their ability to identify all AI agents in their systems. This lack of visibility can lead to unauthorized access and data breaches, making it crucial for organizations to establish stronger governance frameworks for AI usage. As AI continues to evolve and integrate into various business functions, companies must prioritize security measures to mitigate these risks.
