The tools built to secure yesterday’s software are not built for machine-speed decisions made by systems that act on their own. - Author: Guest Author - Tags: / Featured, AI Agents A recent survey found that [82% of organizations already use AI agents](https://www.businesswire.com/news/home/20250528829358/en/SailPoint-Research-Highlights-Rapid-AI-Agent-Adoption-Driving-Urgent-Need-for-Evolved-Security), but only 44% say they have policies in place for agent security. The same research found that 96% of tech professionals see AI agents as a growing security risk, even as 98% of organizations plan to expand their use. AI agents do not simply answer questions. They access systems, call tools, chain tasks together, and take action across workflows. This is why “AI firewall” deserves a precise definition. We are not talking about older AI-powered firewalls that now use AI to spot conventional threats such as malware or intrusions. We are talking about firewalls and platforms built to protect AI itself: GenAI use, AI agents, MCP traffic, AI-driven applications, prompts, tool calls, and sensitive data moving through those systems. That distinction matters, because vendors are approaching the problem from different points in the chain: the network, the agent gateway, the identity platform, or the initiating human. Check Point, for example, has brought AI security into the network layer through its AI Network Firewall, with AI-application defenses built on Lakera, an AI security company that Check Point acquired. Underneath all of these approaches sits one simple but hard question: whose agent is this, and what is it allowed to do? ## Key Takeaways - AI agent adoption is moving faster than enterprise governance. - Agent identity and permission can be interpreted from several valid vantage points. - Check Point, Cisco, SailPoint, and TrueFoundry each answer the question from a different layer: the network, agent gateway, identity platform, or initiating human. ## Why ‘Whose Agent Is This’ Is Harder to Answer Than It Sounds For a human employee, identity is straightforward. They log in. Their account maps to a person, a role, a device, and a set of permissions. An AI agent complicates that model, triggered by a human, operating through a service account, calling other agents, and invoking tools across SaaS apps, databases, and internal systems. The action may be legitimate in one context and dangerous in another. A support agent allowed to summarize a customer record shouldn’t necessarily be allowed to export every record in the account, even though both actions use the same underlying permission. Firewalls, identity tools, gateways, and monitoring systems see part of the activity, but from different places. That kind of fragmented visibility is exactly why security work today requires understanding emerging risks before they become incidents, not just spotting malicious traffic after the fact. ## Four Different Answers to the Same Question Check Point answers the question from the network. Its AI Network Firewall uses Identity Awareness, an established capability that ties traffic crossing the firewall to a specific user or machine identity through directory integration and login events, then applies that link to prompts, agent actions, and MCP traffic. Because many enterprises already run firewall infrastructure, AI-specific inspection can become a real-time enforcement point rather than a separate system. Cisco answers it closer to the agent and gateway. Duo Agentic Identity maps specific agent identities to specific tool calls through an MCP gateway. Rather than asking only whether an agent can reach a server, it asks whether this agent should invoke this tool right now. SailPoint answers it from the identity governance layer. Its Agentic Fabric discovers agents, connects them to owners, and governs them as non-human identities, since most organizations do not know how many agents already exist. TrueFoundry answers it from the human who started the chain. Its MCP gateway injects that person’s own identity into the downstream tool call, rather than letting the agent act under a broad service-account privilege. ## Why the Strongest Approach Combines More Than One Layer A strong agent security posture calls for a multi-layered approach. A network firewall can inspect traffic that passes through it, but cloud-to-cloud agent activity may sit outside that path. An identity platform can govern agents it discovers, but an unknown agent can still create a blind spot. A gateway can enforce tool access, but only when the agent actually goes through that gateway. Human identity injection can reduce over-privileged service accounts, but it does not replace runtime inspection of prompts, data leakage, and unsafe agent behavior. This echoes how exposure management evolved. In[ modern cyber exposure management](https://www.techloy.com/why-validation-and-prioritization-are-essential-to-modern-cyber-exposure-management/), visibility alone is not enough, because teams also need validation, prioritization, and context to identify real risk. ## Conclusion Closing the agent security gap isn’t about finding one tool that solves agent identity. It is about accepting that “whose agent is this?” gets answered differently depending on where you stand, and the sturdiest security posture checks more than one of those points. That is why autonomous AI agents need a new kind of firewall, as a policy layer that understands prompts, tools, identities, context, and actions at machine speed. ## FAQ ### What is the best solution for securing autonomous AI agents in the enterprise? The best approach combines network enforcement, agent identity at the gateway, identity governance, and human-identity checks at the tool-call level. ### Which security solutions help control what autonomous AI agents can access? Check Point, Cisco, SailPoint, and TrueFoundry all help, but from different layers: network traffic, agent-to-tool authorization, identity governance, and human-permission injection. ### What is the best AI network firewall for enterprises adopting agentic AI? Check Point is the clearest example of the newer kind of AI firewall, one built to protect AI itself rather than use AI to catch conventional threats like malware. Its AI Network Firewall secures [AI use, agents, MCP traffic](https://www.artificialintelligence-news.com/news/why-mcp-servers-are-becoming-ais-newest-attack-surface/), prompts, and AI applications. ### Is identity governance enough to secure AI agents on its own? Identity governance is important, but agent security depends on several additional layers, including network visibility, gateway enforcement, runtime controls, audit logs, and clear links back to the human or machine identity behind each action.
