European businesses are racing toward an AI agent revolution with 96% adopting or planning to deploy these systems by 2026, creating unprecedented security vulnerabilities that demand immediate governance strategies. Okta executives warn that without proper controls, organizations risk catastrophic data breaches as AI agents gain access to sensitive systems, payment information, and corporate data.

The AI Agent Permissions Problem
AI agents require extensive permissions to function effectively, accessing everything from corporate calendars and email systems to credit card details and proprietary company information. This creates what security experts call the “permissions paradox” – the more capable an AI agent becomes, the more dangerous its potential compromise. Stephen McDermid, Okta’s EMEA CISO, explains the urgency: “Everybody’s under pressure to do more with less – AI is a very quick way of doing that, but it’s also a very quick way of opening up some risks, exposing data, exposing your users potentially as well.”
The fundamental challenge lies in AI’s inherent gullibility and susceptibility to manipulation. Unlike human employees who can exercise judgment, AI agents follow instructions precisely, making them vulnerable to sophisticated social engineering attacks. According to Gartner research, AI security incidents are projected to quadruple by 2027 as adoption accelerates without corresponding security measures. The recent McDonald’s AI recruitment platform breach exposed 64 million records, demonstrating how even basic security failures can lead to massive data exposure when AI systems handle sensitive information.
Real-World Consequences and Regulatory Risks
The security implications extend far beyond theoretical concerns, with tangible financial, legal, and regulatory consequences awaiting organizations that fail to secure their AI deployments. Shiv Ramji, Auth0 President, emphasizes the multifaceted nature of the risk: “It’s sensitive data leakage, your private information is exposed and the risk is everything from legal to financial, to even running afoul of regulations in different countries.” The EU AI Act establishes strict requirements for high-risk AI systems, including mandatory risk assessments and transparency obligations that many current AI agent deployments would struggle to meet.

Financial institutions face particularly severe consequences, as AI agents handling payment information could trigger compliance violations under regulations like PCI DSS if compromised. The interconnected nature of modern business systems means a single compromised AI agent could provide attackers with access to multiple systems, amplifying the damage potential. Recent analysis from IBM’s Cost of a Data Breach Report 2024 shows that AI-related security incidents cost organizations an average of $4.5 million, 15% higher than conventional breaches due to the complexity of containment and recovery.
Building Effective AI Agent Governance
Okta’s approach to securing what they term “Non-Human Identities” focuses on integrating AI agents into existing identity security frameworks with specific controls tailored to autonomous systems. The company advocates for least-privilege access principles, continuous monitoring for anomalous behavior, and comprehensive audit trails to track every action taken by AI agents. McDermid stresses the importance of proactive security: “Everybody has to start putting the security in place before they start playing with AI because unfortunately, you’ve seen the headlines, there’s already been some examples of breaches going on.”
The platform’s security fabric identifies risky configurations and manages agent permissions dynamically, ensuring agents only access necessary resources for required timeframes. This includes detecting when AI agents begin exhibiting “rogue” behavior patterns that could indicate compromise or malfunction. Okta has also introduced Cross App Access (XAA) standards to establish industry-wide protocols for securing AI agent interactions across different applications and services. While McDermid acknowledges “it’s not going to be the silver bullet that stops all attacks,” he believes these standards represent “the best opportunity to make sure we get technical capabilities there within the products and services we’re offering.”
The Collaborative Security Imperative
Addressing the AI agent security challenge requires unprecedented collaboration across the cybersecurity industry, as threat actors already share techniques and platforms to maximize their effectiveness. McDermid highlights the asymmetry in current security practices: “Threat actors are actually sharing techniques, they’re sharing platforms. They’re working together as a cohort and customers and organizations don’t. I think that’s where we need to improve.” This collaborative gap gives attackers a significant advantage in developing and deploying new attack methods against AI systems.
Organizations must prioritize learning from security incidents and continuously assessing their exposure to emerging AI-specific threats. The Cybersecurity and Infrastructure Security Agency (CISA) recommends regular security assessments specifically targeting AI systems, including testing for prompt injection vulnerabilities and training data poisoning. McDermid concludes with practical advice for security teams: “You have to keep trying and keeping governance over these controls and maintaining that cyber hygiene because if you’re not aware of what the attacks look like then you’re not assessing your own exposure against them.”
