Hey there! Have you heard about the rise of AI agents in enterprises? They’re popping up everywhere, with up to 79% of companies implementing them, according to a recent PwC report. But along with the benefits, they’re also bringing new security risks.
When an agentic AI breach occurs, companies tend to focus on assigning blame rather than addressing the systemic failures that allowed it to happen in the first place. According to Forrester’s Predictions 2026: Cybersecurity and Risk report, the first major breach involving AI agents will lead to dismissals and put pressure on CISOs and CIOs to deploy AI quickly while minimizing risks.
What’s in store for CISOs in 2026?
For those in organizations competing globally, the next year will be challenging as governments tighten regulations on critical communication infrastructure. The EU is expected to establish its own exploited vulnerability database, leading to a demand for regionalized security professionals that CISOs will need to recruit fast.
Additionally, quantum-security spending is projected to increase, as enterprises rush to adopt quantum-resistant cryptography to combat evolving threats.
Among the challenges CISOs will face in 2026, agentic AI breaches and weaponized AI are highlighted as particularly dangerous.
How are CISOs tackling agentic AI threats?
According to Jerry R. Geisler III, CISO at Walmart Inc., the adoption of agentic AI introduces new security risks like data exfiltration and cross-agent collusion. Walmart’s strategy involves proactive security controls using advanced AI Security Posture Management to ensure continuous risk monitoring, data protection, and regulatory compliance.
Identity & access management has become a key focus for many companies, with a shift towards modernizing IAM stacks while maintaining least privilege principles.
Sam Evans, CISO of Clearwater Analytics, shared his concerns about potential data breaches involving AI engines and how his company addressed these challenges by implementing innovative solutions like enterprise browsers from Island.
Boardrooms are urging CISOs to secure AI applications and tools to unlock productivity gains without compromising security.
As the pace of agent deployments accelerates, CISOs are under pressure to deliver value quickly. George Kurtz, CEO of CrowdStrike, emphasized the need for rapid analysis of data to detect and respond to cyber threats swiftly.
Productivity and security are now intertwined, with companies racing to stay ahead of both competition and adversaries.
Walmart’s innovative approach to cybersecurity
At Walmart, innovation is a top priority for keeping defenses strong and reducing risk. The company takes a startup mindset, constantly reevaluating its cybersecurity strategies to align with the latest threats and technologies.
By fostering a culture of innovation, Walmart has managed to enhance its cybersecurity defenses while contributing to business growth.
Other companies, like Clearwater Analytics, are also investing in cyberdefenses to protect against agentic AI cyberattacks.
Through interviews with CISOs and security teams, seven key strategies have emerged for securing enterprises against agentic AI threats.
Seven ways CISOs are safeguarding their organizations
1. Visibility is crucial: Maintaining a real-time inventory of systems and tracking interactions at the agentic level is essential for resilience.
2. Reinforce API security: Monitoring risk at API layers and leveraging AI Security Posture Management for regulatory compliance are vital.
3. Manage autonomous identities strategically: Treating AI agent access like compromised credentials and deploying IAM frameworks that scale are key.
4. Upgrade to real-time observability: Implementing live intelligence layers for rapid threat detection is critical.
5. Embed proactive oversight: Balancing innovation with control and integrating human-in-the-middle workflows is essential.
6. Make governance adaptive: Continuous adaptation of compliance policies and integration into operational workflows is necessary.
7. Engineer incident response ahead of threats: Developing and testing response playbooks before agentic threats strike is crucial for effective incident management.
Agentic AI and the evolving threat landscape
As Forrester predicts, the first major agentic breach will expose organizations that fail to adapt to new governance, security, and observability standards. CISOs must act urgently to stay ahead of quantum threats and secure their enterprises against evolving risks.
By implementing proactive security measures and embedding governance into daily operations, enterprises can turn risk management into a strategic advantage, outpacing competitors and staying resilient against cyber threats.
