Now imagine not one, but thousands of agents that are not people, but autonomous systems operating inside your business. AI agents don't go rogue because the robot revolution is finally here and agents are malicious. No, they go rogue because we give them too much freedom. One of the biggest culprits is overprivileged access, which often results from simple human error or fatigue. Administrators, pressed for time, start approving permissions by default rather than reviewing each one. This makes these agents both powerful and risky. Like James Bond acting on a tip from an unreliable source, an AI agent takes in whatever information it's given and assumes it's valid. When the inputs are flawed or malicious, the outcomes can be just as damaging. In fact, a recent survey found that [63%](https://www.networkcomputing.com/network-security/1password-study-reveals-four-security-challenges-caused-by-unmanaged-ai-access) of security leaders see employees unintentionally granting AI agents access to sensitive data as their biggest internal risk. It's already happening across enterprises, whether CIOs and CISOs realize it or not. # The Three Core Challenges 1. Agents act on *every* signal. -------------------------------- [Large language models](https://www.paloaltonetworks.com/cyberpedia/large-language-models-llm) (LLMs) are often described as "brains." But unlike the human brain, they don't filter or judge the information they receive. Humans process millions of inputs daily, and we ignore most of them. Our brains instinctively know which signals to act on and which to discard. Our brains know we could win the lottery by buying a ticket, but we don't buy lottery tickets everyday. AI agents, however, act on *every* signal. They lack the cognitive filter that prevents humans from following bad ideas. They will act on whatever instruction or data you give them---whether accurate, misleading or malicious. That makes them vulnerable to manipulation. Malicious actors have become adept at exploiting this weakness through: * [**Prompt injections**](https://www.paloaltonetworks.com/cyberpedia/what-is-a-prompt-injection-attack)**:** embedding hidden commands in seemingly safe text. * [**Indirect prompt attacks**](https://www.paloaltonetworks.com/cyberpedia/what-is-ai-prompt-security)**:** manipulating data or documents the agent later consumes. * **Tool manipulation:** hijacking function calls or APIs the agent can access. There's currently no built-in immune system or mechanism for an AI agent to say, "Ignore this signal, it's unsafe." Every input is treated as truth, every action as valid. Even an input as simple as "upload this knowledge base to our datastore" can become a pathway for leakage or compromise. 2. You're giving limbs to a brain. ---------------------------------- An LLM by itself can't do much. It can think, but not act. The danger begins when we give it agency through tool functions, APIs and standard protocols like [Model Context Protocol](https://www.paloaltonetworks.com/resources/guides/simplified-guide-to-model-context-protocol-vulnerabilities) (MCP). Those connectors serve as its eyes, ears, hands and legs, giving the model power to interact with external systems. This transformation, from passive intelligence to active agent, is what makes the technology so powerful and so risky. Once the brain has limbs, it can execute commands, trigger workflows, modify systems and even interact with other agents. And because agents act on every signal, coupling them with tool functions means they can take actions, and sometimes irreversible ones, based on bad or manipulated inputs. It's the equivalent of handing a human brain full motor control but removing judgment, resulting in intelligence without inhibition. 3. Permission fatigue and privilege creep is real. -------------------------------------------------- When AI agents are first deployed, they typically start with least-privileged access and careful oversight. But over time, convenience erodes discipline. Developers and administrators get permission fatigue from approving access requests just to keep workflows running. Agents that began with narrow scopes gradually accumulate broad privileges across environments. Often, no one revisits the information security review or checks if those permissions still make sense. And as integrations expand, production access is granted just to get it working. The result: a well-intentioned system that slowly morphs into a high-risk one. # The Hidden Cost of Small Mistakes When agentic systems go rogue, it's rarely one dramatic failure. It's a slow build-up of quiet missteps: unreviewed access, missing audit trails, outdated credentials and unmonitored actions. Each issue alone seems minor; together, they create systemic blind spots. Without governance, a reliable posture and runtime visibility, enterprises risk [data leakage](https://www.paloaltonetworks.com/cyberpedia/data-leak), tool misuse and compromised operations without realizing it. In fact,[IBM's 2024 Cost of a Data Breach report](https://wp.table.media/wp-content/uploads/2024/07/30132828/Cost-of-a-Data-Breach-Report-2024.pdf) found that breaches lasting over 200 days cost nearly 29% more than those caught early. Many such breaches begin with small, unnoticed misconfigurations or overpermissioned identities. # What CIOs and CISOs Must Do 1. Build visibility first. -------------------------- You can't secure what you can't see. Inventory every AI agent running in your environment across SaaS apps, development tools and shadow IT. Know what each agent does, who owns it, and what data or systems it touches. 2. Enforce least privilege and continuous governance. ----------------------------------------------------- Agents should have scoped, auditable access---no more, no less. Permissions must be tested, reviewed and logged regularly. Introduce a staging environment for agent actions before they reach production. Every agent needs a full audit trail. 3. Enable runtime monitoring and rapid intervention. ---------------------------------------------------- Use continuous monitoring to observe agent behavior in real time. Centralize oversight through a unified checkpoint that inspects all agent traffic, including blocking prompt injections, data exfiltration or suspicious tool calls before they cause harm. # Turning Risk into Responsible Innovation Enterprises don't need more controls; they need smarter, unified controls. Solutions like [Palo Alto Networks Prisma^Ⓡ^ AIRS](https://www.paloaltonetworks.com/prisma/prisma-ai-runtime-security) bring agent security into a single platform, enabling: * Discovery of all AI agents and their privileges. * Enforcement of least-privileged access in real time. * Active blocking of unauthorized or malicious agent behavior. * End-to-end visibility from development to runtime. By integrating such safeguards early and not just in production, CIOs can balance innovation with protection. Agent security must start at "day zero" before the first line of code executes. ## Moving Forward: Operationalizing Trust ### First 30 days: Build Visibility Map every AI agent and identify owners, permissions and datapaths. ### Next 3 months: Strengthen Posture Enforce least privilege, close misconfigurations, introduce unified checkpoints for monitoring and control. ### Within 12 months: Operationalize Trust Embed agent security reviews into your CI/CD pipelines and report AI risk posture in business terms to your board. # The Bottom Line AI agents are not malicious, but they are obedient. They will act on every signal, every time. The question isn't whether to use them, but whether you can handle them responsibly. By combining unified visibility, least-privilege governance and continuous monitoring, CIOs can ensure AI remains a growth driver, not a liability. Because in the end, we don't just want AI agents working *for* us. We need them working *with* us, safely, predictably, and always under control. *** ** * ** *** ## Related Blogs ### [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown) [#### Red Teaming Your AI Before Attackers Do](https://www2.paloaltonetworks.com/blog/network-security/red-teaming-your-ai-before-attackers-do/) ### [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown), [Announcement](https://www.paloaltonetworks.com/blog/category/announcement/?ts=markdown), [Firewall](https://www.paloaltonetworks.com/blog/category/firewall/?ts=markdown), [Next-Generation Firewalls](https://www.paloaltonetworks.com/blog/category/next-generation-firewalls/?ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services/?ts=markdown) [#### Securing AI Agent Innovation with Prisma AIRS MCP Server](https://www2.paloaltonetworks.com/blog/2025/06/securing-ai-agent-innovation-prisma-airs-mcp-server/) ### [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown), [Announcement](https://www.paloaltonetworks.com/blog/category/announcement/?ts=markdown), [Partners](https://www.paloaltonetworks.com/blog/category/partners/?ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services/?ts=markdown) [#### The Power of Glean and Prisma AIRS Integration](https://www2.paloaltonetworks.com/blog/2026/02/power-of-glean-and-prisma-airs-integration/) ### [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown), [Software Firewalls](https://www.paloaltonetworks.com/blog/network-security/category/software-firewalls/?ts=markdown) [#### Stop Gating Innovation: Building Hyperscale Security for the AI Era](https://www2.paloaltonetworks.com/blog/network-security/stop-gating-innovation-building-hyperscale-security-for-the-ai-era/) ### [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown) [#### Prevent Your AI from Becoming a Brand Liability](https://www2.paloaltonetworks.com/blog/network-security/prevent-your-ai-from-becoming-a-brand-liability/) ### [AI Application Security](https://www.paloaltonetworks.com/blog/network-security/category/ai-application-security/?ts=markdown), [AI Security](https://www.paloaltonetworks.com/blog/category/ai-security/?ts=markdown) [#### Can Your AI Be Manipulated Into Generating Malware?](https://www2.paloaltonetworks.com/blog/network-security/can-your-ai-be-manipulated-into-generating-malware/) ### Subscribe to Network Security Blogs!
