AI agents are crossing an important threshold.

They are moving from assistants that respond to us to autonomous systems that reason, plan, and act on our behalf. They can write and execute code, access enterprise data, call tools and APIs, and keep working toward a goal with limited human intervention.

That changes the security model.

An autonomous agent is designed to find a way to accomplish its objective. If one path is blocked, it reasons about another. That is what makes agents powerful, and it is why models’ built-in prompt guardrails alone are not enough.

The harness can guide what an agent should do. Security must control what an agent can do. That requires security authority outside the agent itself.

Palo Alto Networks and NVIDIA Team Up to Secure Agentic AI

NVIDIA provides the accelerated computing platform, secure runtime foundation, and reference system design for agentic AI. Palo Alto Networks brings the AI security capabilities enterprises need to govern interactions, protect workloads, and control identity and access.

Together, we are extending security across three areas: AI governance with Prisma AIRS AI Gateway, runtime protection with Prisma AIRS AI Runtime Security, and Agent Identity Security powered by IDIRA.

This is the focus of our expanded collaboration with NVIDIA on the NVIDIA Open Agent Safety Platform reference design.

a) Prisma AIRS AI Gateway on NVIDIA Vera CPU

Our forward-looking architecture includes Prisma AIRS AI Gateway software running on NVIDIA Vera CPU systems, bringing AI governance and enforcement closer to infrastructure designed for agentic workloads.

The AI Gateway is the real-time enforcement point for AI Governance, Runtime, and Identity security. It continuously verifies agent identities, enforces strict least-privilege access, redacts sensitive data before it is exposed, and deeply inspects every interaction—stopping unauthorized actions before they ever reach critical host systems or cloud endpoints.

• Operationalize AI agents: Connect applications and agents to thousands of models and tools through one control point, with the reliability and flexibility to scale AI across the enterprise.
• Track usage and control costs: Monitor every AI interaction across your company to see exactly what teams are doing, track your spending, and restrict access to approved tools only.
• Enforce agent security across the enterprise: Block sensitive data exposure and malicious commands in real time, and verify agent identity before actions are taken.

b) Announcing Prisma AIRS AI Runtime Security on NVIDIA BlueField

The Palo Alto Networks AI Runtime firewall running natively on NVIDIA BlueField DPUs extends Zero Trust protection to the front-end network traffic of the AI factory and to the AI Edge, creating a tamper-proof boundary immune to application-layer attacks. Drawing on the NVIDIA Sentry reference design, Prisma AIRS AI Runtime Security accelerated on NVIDIA BlueField delivers: 

• Hardware-Isolated Boundaries: Tamper-proof boundary, ensuring a compromised model or a rogue agent can never bypass runtime controls.
• Agentless Behavioral Introspection: Monitor agent execution paths, memory structures, and tool calls with NVIDIA DOCA Argus with zero CPU overhead, and feed real-time telemetry directly into Cortex XSIAM for automated observation, analysis, and remediation.
• Zero Trust Governance: Strict least-privilege access is enforced across the network and external APIs by default, delivering a verifiable audit trail for every allow and block action.

c) IDIRA Agent Identity Security

As agents gain greater autonomy, identity becomes fundamental to controlling what they can access and what actions they can take.

Looking ahead, we plan to integrate NVIDIA OpenShell with upcoming Agent Identity Security capabilities from Idira, including identity and secrets management for the OpenShell sandbox and agent identity broker service on NVIDIA BlueField. This will help organizations apply identity-based controls and least-privilege access to agents without relying on persistent human credentials.

The Path Ahead: Security at Scale for Enterprise Agents

As agents become more autonomous, governance must extend to identity. Prisma AIRS AI Gateway will also serve as an enforcement point for Agent Identity Security powered by IDIRA. We are also expanding to include Agent Identity Broker support directly on NVIDIA BlueField, providing identity verification and access governance independently of the host environment.

Together, these capabilities are designed to prevent unauthorized execution, reduce standing access, and stop privilege escalation as agents interact with enterprise systems.

As agents gain more autonomy, enterprises need consistent control over how they connect and what they can access.

Our work with NVIDIA brings those controls closer to where agentic workloads run, while Palo Alto Networks provides the security policy, governance, and enforcement enterprises need to manage them. 

To learn more about our GA of AI Runtime Security on the BlueField DPU, read our blog — Palo Alto Networks Announces Support for NVIDIA Enterprise AI Factory.

The next phase of AI will be defined not only by what agents can do, but by whether enterprises can trust them to operate safely at scale.

Securing Every Environment at the Speed of Frontier AI

Recognized as a Leader for the second consecutive time and positioned furthest for Completeness of Vision. Palo Alto Networks is advancing hybrid mesh firewall with one integrated platform for preemptive protection, agentic operations, AI runtime security and quantum-safe security across the enterprise.

 

We are proud to share that Palo Alto Networks has been named a Leader in the 2026 Gartner® Magic Quadrant for Hybrid Mesh Firewall for the second consecutive time, and positioned furthest for Completeness of Vision.

We believe this recognition reflects the strength of our approach to network security: one natively integrated platform that delivers consistent protection, policy and operations across every environment.

It also comes at a pivotal moment for cybersecurity. Frontier AI is collapsing the time between vulnerability discovery and exploitation. AI applications and agents are creating new infrastructure and data risks. At the same time, the cryptographic reset is forcing enterprises to rethink how they establish and maintain digital trust.

Fragmented firewall architectures and manual security operations were never designed for this speed, scale or complexity, and can no longer keep pace.

One Platform Across Every Environment

Hybrid environments have traditionally required organizations to deploy and manage different security products across data centers, clouds, branches, campuses and remote users. The result is often fragmented policy, inconsistent protection and operational complexity.

Palo Alto Networks transforms hybrid mesh firewall from a collection of enforcement products into a unified, intelligent security platform, powered by Precision AI.

The  Strata Network Security Platform is our Hybrid Mesh Firewall, spanning hardware  (PA-Series), virtual (VM-Series), cloud-native (Cloud NGFW) and firewall-as-a-service (SASE) deployments with consistent policy, shared intelligence and threat prevention across environments. 

Strata Cloud Manager provides unified policy, visibility and AI-driven operations across these enforcement points. Beyond traditional firewall environments, the platform extends protection to the browser with Prisma Browser and to AI applications, models and agents with Prisma AIRS®.

Cloud-delivered security services, including Advanced Threat Prevention, Advanced WildFire, Advanced URL Filtering, and Advanced DNS Security deliver consistent, inline prevention across environments. Intelligence discovered in one part of the platform can strengthen protection everywhere, turning every enforcement point into a real-time prevention layer.

The Hybrid Mesh Firewall Market Is Evolving

Gartner’s 2026 Hybrid Mesh Firewall research describes a market moving toward more automated, intelligence-driven security platforms as organizations manage increasingly complex hybrid environments. 

The report identifies several trends shaping the evolution of hybrid mesh firewall, including the growing adoption of cloud-based management, AI-driven threat prevention, automation through LLM-based assistants, post-quantum cryptography and security capabilities for AI applications and workloads.

As these requirements evolve, organizations need a network security architecture that can deliver consistent protection and operations across hybrid environments while preparing for emerging AI and quantum-era risks.

Advancing Hybrid Mesh Firewall for the Frontier AI Era

Against this backdrop, Palo Alto Networks continues to advance the Strata Network Security Platform for the Frontier AI era.

Preempt attacks earlier: Advanced Threat Prevention Plus uses Frontier AI-powered vulnerability discovery and Frontier Virtual Patching to deliver preemptive protections, including before vulnerabilities are publicly disclosed or official patches are available.

Disrupt attacker infrastructure: Advanced IP Defense continuously identifies, validates and blocks attacker-controlled infrastructure in real time - even when adversaries use direct-to-IP communications, proprietary encryption, residential proxies or trusted cloud infrastructure to evade traditional security signals.

Operate at machine speed: Six purpose-built Network Security Agents in Strata Cloud Manager assist teams with deployment, troubleshooting, configuration management, posture optimization, threat investigation and data protection, with built-in guardrails and human oversight.

Secure AI and modernize digital trust: Prisma AIRS helps secure AI applications, models and agents across the AI lifecycle, while Quantum-Safe Security and Next-Generation Trust Security help organizations identify cryptographic risk and modernize digital trust. Read more about Palo Alto Networks’ approach to securing AI.

Together, these capabilities help organizations reduce exposure before attacks succeed, operate at machine speed, secure AI infrastructure and modernize digital trust for the post-quantum era.

Proven Security, Performance and Scale

A unified platform must deliver not only breadth, but also effective protection and reliable performance under demanding conditions.

Independent SecureIQLab testing demonstrated 99% security efficacy, with Palo Alto Networks scoring approximately 20 points higher than the next-best tested vendor. Miercom validation demonstrated up to 2–8 times higher AI traffic throughput, along with strong TLS inspection and stable performance under sustained load.

More than 75,000 organizations around the world rely on Palo Alto Networks to consolidate security, improve visibility and reduce risk across their hybrid environments.

This global scale provides intelligence that continuously strengthens the platform. Every attempted attack expands what the platform can learn, and every new detection can become protection for all customers.

Defining the Future of Hybrid Mesh Firewall

We believe being named a Leader for the second consecutive time reinforces our conviction in an integrated platform that delivers consistent prevention and operations everywhere an enterprise operates.

But we believe industry leadership is also about preparing customers for what comes next.

As Frontier AI accelerates attacks, autonomous systems reshape security operations and quantum risk changes the foundations of digital trust, enterprises need more than a collection of firewalls. They need an intelligent security platform that can transform shared intelligence into prevention across every environment.

Palo Alto Networks is building that future, helping organizations reduce exposure before attacks succeed, operate at machine speed, secure AI infrastructure and modernize digital trust for the post-quantum era.

Enterprises are seeing an unprecedented surge in AI coding adoption with spend on AI coding tools projected to top $13 billion in this calendar year¹, compounding at more than 60% annually. For engineering teams, the benefits are unmistakable: accelerated output, supercharged productivity, and operational overheads dramatically reduced.

But these AI solutions are no longer just offering helpful coding suggestions. Today’s coding agents are able to assume a user’s identity, modify file systems, execute arbitrary terminal commands, and connect directly into core business systems.

Traditional cybersecurity architectures were engineered around three foundational assumptions: known software, human users, and human-speed actions. AI coding fundamentally dismantles all three.

The Breakdown of Traditional Controls for Secure Software Development.

As AI-assisted coding accelerates, traditional security controls are quickly falling behind, creating four volatile vectors of risk: 

• Shadow AI at Enterprise Scale: Coding agents, IDE (Integrated Developer Environment) extensions, skills, and MCP (Model Context Protocol) servers permeate the enterprise before security teams even know they exist. In 2026, 68% of organizations reported lacking visibility into the AI tools their developers were actually using, and 57% of employees reported using AI coding tools without formal IT approval². 
• Risky Behavior by Agents: AI coding agents have the capability to  change files, access company resources, and execute system commands in milliseconds. In one documented³ AI-enabled intrusion chain, an agent executed 17,600 actions in 4.5 days creating a timeline no human-enabled SOC can manually govern. 
• Blurred Identity and Attribution: Machines now outnumber human identities 109 to 1⁴. And, because agents frequently operate using human credentials, distinguishing developer action from autonomous agent action becomes nearly impossible. When anomalies occur, this obscured attribution further complicates root causing the issue. 
• Uncontrolled Connections, Data, and Cost: Agents connecting to external models, MCP servers, and third-party tools outside the company, presents another distinct but related issue. All these connections also quietly increase consumption of AI resources, and separately exacerbate the risk of sensitive IP leaks. A recent survey found⁵ that 93% of enterprises exceeded their AI budgets with 20-30% of AI spend being entirely unaccounted for.  

Resetting the Controls for AI-Native Development.

Securing AI coding inside an enterprise requires a proactive, platform-centric approach:

• Discover shadow AI and what it’s using: Gain complete visibility across every model, agents, plugin, skill, and MCP to neutralize risky or unsanctioned components before they perform harmful actions.
• Assess supply chain risks: Scan skills, models, and MCP to make sure they are trusted.
• Protect identity and prompt: Inspect prompts, model outputs, and autonomous interactions in real time. Provision verified, task-scoped identities for agents and eliminate standing privileges.
• Govern data, actions, and cost: Enforce zero-trust boundaries over external model connections, governing access to file systems, sensitive corporate data, and establishing hard policies over AI resource consumption and spend.

The Platformization Advantage for Superior Governance.

Today, endpoint visibility, LLM traffic, token consumption, agent identity and actions are fragmented across disparate solutions introducing visibility gaps and creating new risks for enterprises. Palo Alto Networks delivers AI coding security natively with an integrated platform to secure what gets installed, what runs, what data leaves the enterprise, and which identity is used.

AI coding tools will continue to evolve, as they should. But your builders don’t have to choose between speed and security. The goal is not to slow down developer momentum, but to provide the security controls that serve as scaffolding for your teams to innovate faster and with complete confidence.

Secure your AI. We’ve got next.
