TrojAI Launches First-of-its-Kind Firewall for AI Agent Security, Addressing Emerging MCP Risks

SAN FRANCISCO, CA – November 13, 2025 – As enterprises increasingly deploy sophisticated AI agents to automate tasks and drive innovation, a critical security gap is emerging. Today, TrojAI announced the launch of Defend for MCP, a dedicated firewall designed to protect agentic AI workflows leveraging the Model Context Protocol (MCP). This launch addresses a growing concern among security professionals about the unique risks associated with these autonomous systems, and marks a significant step towards securing the next generation of AI applications.

The Rise of Agentic AI and the MCP Layer

Agentic AI, which empowers AI systems to act autonomously and make decisions without constant human intervention, is rapidly gaining traction across industries. This shift is fueled by frameworks like the Model Context Protocol (MCP), which enables AI agents to interact with servers, tools, and data sources. However, this increased autonomy and interconnectedness also introduces new attack vectors and security vulnerabilities that traditional security solutions are ill-equipped to handle.

“Traditional security tools simply lack the visibility needed to monitor and control traffic flowing within the MCP layer,” explains a security analyst at a major financial institution. “These systems are nondeterministic and operate in a fundamentally different way than traditional applications. We were actively looking for a solution that could address this gap.”

Addressing a Critical Security Gap

TrojAI Defend for MCP directly addresses this growing need. The solution provides comprehensive security for agentic AI workflows by monitoring and enforcing policies on traffic flowing to and from MCP servers. Key features include a registry for approved servers, real-time traffic visibility, tool change detection, and a comprehensive policy engine.

“We recognized that securing agentic AI requires a fundamentally different approach,” says a TrojAI spokesperson. “Defend for MCP isn’t just another firewall; it’s a purpose-built solution designed to protect the unique characteristics of these autonomous systems.”

Understanding the MCP Threat Landscape

The risks associated with MCP deployments are multifaceted. Security experts identify several key threat areas, including:

• Shadow MCP Instances: Unauthorized servers operating outside of approved governance frameworks pose a significant risk.
• Tool Tampering: Malicious actors can compromise or modify tools used by AI agents to manipulate their behavior or steal data.
• Prompt Injection Attacks: Crafted inputs can trick AI agents into performing unintended actions or revealing sensitive information.
• Data Exfiltration: AI agents can be exploited to steal confidential data from connected systems.

“The potential for damage is significant,” notes a cybersecurity consultant specializing in AI risk management. “An attacker could leverage a compromised AI agent to disrupt critical business processes, steal intellectual property, or even launch attacks against other systems.”

How TrojAI Defend for MCP Works

TrojAI Defend for MCP operates by providing deep visibility into all traffic flowing within the MCP layer. The solution’s key features include:

• MCP Server Registry: Organizations can register and approve all MCP servers within their environment, eliminating shadow instances.
• Real-Time Traffic Visibility: Defend for MCP provides detailed insights into all communication between AI agents, servers, and tools.
• Tool Change Detection: The solution continuously monitors tool definitions and alerts administrators to any unauthorized modifications.
• Comprehensive Policy Engine: Administrators can create and enforce granular policies to control access, prevent malicious activity, and ensure compliance.
• Runtime Enforcement: Defend for MCP blocks unauthorized servers, prevents the use of unapproved tools, and stops malicious attacks in real-time.

“The solution isn’t just about detecting threats; it’s about preventing them before they can cause damage,” says a security architect who has evaluated the product. “The ability to enforce policies at runtime is critical for protecting these autonomous systems.”

The Broader Security Landscape for Agentic AI

While TrojAI Defend for MCP is a significant step forward, it’s important to recognize that securing agentic AI requires a holistic approach. Other essential security measures include:

• Robust Identity and Access Management: Controlling who has access to AI agents and the data they use is crucial.
• Data Encryption: Protecting sensitive data both in transit and at rest is essential.
• Regular Security Audits: Identifying and addressing vulnerabilities before they can be exploited is critical.
• AI-Specific Threat Intelligence: Staying informed about the latest threats targeting agentic AI systems is essential.

“Securing AI is a shared responsibility,” says a security researcher specializing in machine learning security. “Organizations need to implement a layered security approach that combines technology, processes, and people.”

Looking Ahead: The Future of AI Security

As agentic AI continues to evolve, the security challenges will become even more complex. Experts predict that future security solutions will need to incorporate advanced capabilities such as:

• AI-Powered Threat Detection: Leveraging machine learning to identify and respond to evolving threats.
• Behavioral Analytics: Detecting anomalies in AI agent behavior that could indicate malicious activity.
• Automated Security Response: Automatically responding to threats without human intervention.

“The future of AI security will be defined by automation and intelligence,” says a security analyst specializing in AI risk management. “Organizations will need to leverage the power of AI to protect themselves from AI-powered attacks.”

TrojAI’s launch of Defend for MCP marks a critical step towards securing the next generation of AI applications. By addressing the unique security challenges posed by agentic AI, the company is helping organizations unlock the full potential of this transformative technology while mitigating the associated risks.
