In this article, we discuss the emerging market for AI agent security as businesses give AI agents access to files, applications, APIs and internal workflows. Each agent can take actions on a company’s behalf, raising questions about identity, permissions, data protection and accountability. We look at the security tools being built to address these risks, along with the investment and M&A activity taking shape around the category. As adoption grows, securing agents will become an increasingly important part of how companies deploy AI across their operations.
