Not if “control” means broad, unrestricted access. An AI agent with network-connected tools can turn a mistaken instruction—or malicious text it encounters in an email, website, file, or API response—into an action on real systems. An agent can be useful more safely when you limit what it can reach, give it only task-specific permissions, and require independent approval for high-impact changes.
What does “control of your network” mean?
The phrase can describe very different deployments. An agent might only fetch public web pages, or it might run commands on a workstation, call internal services, change cloud settings, or transmit files. Those cases do not carry the same risk.
Assess the agent by what it can actually do, not by the label on the product. Consider its connected tools, the systems and destinations those tools can reach, the credentials available to it, and whether it can make changes without a person approving them. A text-only assistant that cannot take actions has a different exposure from an agent that can use a shell, call APIs, edit files, or send network requests.
Why can network access make an agent risky?
Untrusted content can steer an agent
An agent may read external content while completing a legitimate task. A webpage, email, document, or API response can contain instructions intended to manipulate it. OWASP identifies direct and indirect prompt injection among agent risks; it also lists tool abuse, privilege escalation, data exfiltration, excessive autonomy, and misuse of high-impact actions.

NIST technical staff at the Center for AI Standards and Innovation (CAISI) described the problem in a January 17, 2025 technical blog: “Currently, many AI agents are vulnerable to agent hijacking, a type of indirect prompt injection in which an attacker inserts malicious instructions into data that may be ingested by an AI agent, causing it to take unintended, harmful actions.” This is a warning about a vulnerability class, not a measurement of how often agents are compromised.
Tools can turn a bad instruction into an action
If the agent can reach systems or send data outside the organization, an instruction-following failure may have consequences beyond an incorrect answer. Depending on its permissions, it could expose data, modify files or settings, or invoke a service. The risk is determined by the tools, reachable targets, credentials, and approval controls—not by how confidently the agent responds.

OWASP’s secure-coding guidance notes that agentic coding tools may execute commands, install packages, edit files, and access the network on a developer’s machine. In an unsandboxed runtime, a compromised context may inherit the developer’s permissions.

Telling an agent in its instructions to “only read” or “never delete” is not a substitute for enforcing those limits outside the model. The system that executes a tool call should independently check whether the initiating user or session may perform that operation on that target. A model-generated claim that an action is safe is not authorization.

When can an agent have network access more safely?
Limited access can be reasonable when it is necessary for a defined task and the surrounding system constrains what the agent can do. For example, an agent that needs to retrieve information from an approved service may not need a general-purpose shell, write permissions, access to unrelated internal systems, or persistent production credentials.
Use least privilege across several layers: restrict the agent’s tools and operations, limit reachable network destinations, scope credentials to the task, and independently authorize sensitive actions. No single control makes broad access safe. CISA’s May 1, 2026 joint guidance with partner cybersecurity agencies advises limiting agent autonomy and avoiding broad access, particularly to sensitive data or critical systems, while using layered defenses, strong identity management, oversight, threat modeling, continuous monitoring, and regular security assessments.

How to limit what an AI agent can access
- Define the task and its boundaries. List the data the agent must read, the tools and destinations it needs, the changes it may make, and the information that must not leave the environment. Consider likely misuse as well as the intended workflow.
- Remove unnecessary tools and permissions. Grant access by resource and operation. Separate read-only access from write access, and do not give a task shell, administrator permissions, or wildcard access when a narrower tool will do.
- Enforce authorization in the execution layer. For each tool call, check the actor or session, tool, operation, target, and arguments. OWASP’s AI security guidance recommends per-tool and per-operation allowlists, narrowly typed schemas, deny-by-default parsing, and task-scoped ephemeral tokens.
- Constrain network reach. Use runtime isolation, network segmentation, or egress rules to prevent contact with unrelated internal systems and destinations. If a coding task does not need outbound access, OWASP recommends blocking it. Choose an enforcement point appropriate to the deployment: operating-system firewalls, cloud network policies, enterprise controls, or a network firewall appliance may all play a role.
- Keep long-lived secrets out of the runtime. Avoid exposing personal developer credentials, SSH keys, cloud tokens, production credentials, or organization-wide secrets. Prefer credentials that are temporary and limited to the current task.
- Require independent approval for consequential actions. For destructive, administrative, externally visible, or otherwise high-impact operations, have a separate execution component verify approval for the exact tool, target, and parameters before applying the change. Fail closed if authorization, policy lookup, or audit logging fails.
- Log and review activity safely. Record relevant tool calls and outcomes, redact secrets, and alert on unusual tool use or privilege activity. Reassess controls as the agent, systems, and threats change; NIST’s evaluation discussion favors adaptive testing, task-specific analysis, and examining attack success across multiple attempts.
How to compare safer and riskier setups
The following is a practical comparison based on recommendations from OWASP and CISA, not a benchmark ranking of specific agent products.

| Control area | Lower exposure | Higher exposure |
|---|---|---|
| Network reach | Isolated runtime with allowlisted destinations | Arbitrary outbound access or broad access to internal networks |
| Tool permissions | Task-specific, read-only access or a narrowly scoped operation | Shell, administrator, or wildcard tool access |
| Credential lifetime | Ephemeral credentials scoped to the task | Persistent personal or production credentials |
| Action impact | Read, summarize, or propose a change | Change permissions, modify infrastructure, delete, deploy, or transmit sensitive data |
| Authorization | Independent backend checks for each operation | Authorization left to prompts or model output |
| Oversight | Approval of the exact high-impact action | Unreviewed autonomous execution |
| Monitoring | Auditable tool calls, anomaly alerts, and reassessment | Unlogged actions and no review |
What do the official sources establish—and what don’t they?
NIST’s January 17, 2025 CAISI blog discusses agent-hijacking evaluations and identifies four evaluation insights: shared frameworks should improve; evaluations should adapt as systems change; task-specific attack performance can matter alongside aggregate performance; and testing multiple attack attempts may provide a more realistic picture. These are evaluation recommendations, not a universal compromise rate.
The cited official guidance does not establish one prevalence figure that predicts the likelihood of compromise for every agent deployment. A useful risk judgment therefore has to be specific to the tools, network reach, credentials, action permissions, and controls in the system being considered.
