Prisma AIRS Alternative - Developer-First, Self-Serve
Prisma AIRS is a comprehensive enterprise suite. Agentshield is the developer-first alternative you can drop in front of an agent in an afternoon, with prices on the page.
Direct answer
A Prisma AIRS alternative is an AI agent security product that delivers runtime protection without an enterprise-suite procurement cycle. Agentshield is developer-first and self-serve: it blocks prompt injection, enforces tool and data permissions, monitors every action, and keeps an immutable audit trail, drops in front of any agent stack, and publishes its prices. Enterprise options like on-prem and SSO are available, but you do not need a sales call to start.

Where Palo Alto Prisma AIRS is strong
Palo Alto Prisma AIRS is a comprehensive enterprise AI security suite, a strong fit for large organizations standardizing on the Palo Alto platform with a CISO-led rollout.
Where Agentshield is the alternative
Agentshield is built for the developer shipping the agent next week, not a months-long procurement. It is stack-neutral, self-serve, and transparent: a runtime control plane with firewall, permissions, monitoring, and audit that you can deploy in an afternoon, with real prices on the page instead of contact-sales.
Side by side
Agentshield vs Palo Alto Prisma AIRS, honestly.
| Dimension | Agentshield | Palo Alto Prisma AIRS |
|---|---|---|
| Time to deploy | Drop in front of an agent in an afternoon, self-serve. | Enterprise rollout and procurement. |
| Pricing transparency | Real prices on the page. | Contact-sales, opaque pricing. |
| Stack neutrality | Works in front of any agent framework or model. | Strongest within the Palo Alto ecosystem. |
| Core controls | Firewall, permissions, monitoring, audit in one plane. | Comprehensive enterprise AI security suite. |
| Audience | The developer shipping the agent. | The CISO and security org. |
Comparison reflects our understanding of publicly available information and is meant to be fair. Vendors evolve; verify the latest before deciding.
How Agentshield and Prisma AIRS differ in practice
Prisma AIRS 3.0, which Palo Alto Networks shipped in March 2026, is a broad enterprise AI security suite. It bundles an AI runtime firewall, AI model security, AI red teaming, agent discovery across cloud and SaaS, agent identity with RBAC, and posture management into the Palo Alto platform. That breadth is real, and for a large organization already standardizing on Palo Alto it is a genuine strength.
Agentshield is deliberately narrower and closer to the code. It is the runtime control plane a developer drops directly in front of a single agent to block prompt injection, enforce least-privilege tool and data permissions, gate high-risk actions for a human, and write an immutable audit trail. You install it in an afternoon, see prices on the page, and run it in front of any framework or model without a platform commitment.
The honest split: Prisma AIRS is bought by a security organization securing AI across an entire company. Agentshield is bought by the team shipping the agent that goes live next week.
When Prisma AIRS is the better choice
Pick Prisma AIRS when you are a large enterprise that needs to discover and inventory shadow AI and agents across a sprawling estate, when you are already invested in the Palo Alto platform and want AI security under the same console and contract, or when a CISO-led program requires a single vendor to cover model scanning, network security, and AI posture together.
Pick Agentshield when the job is to govern a specific agent that calls tools and takes actions, when you want to be enforcing this quarter rather than after a procurement cycle, and when transparent, self-serve pricing matters. Many teams run both: Prisma AIRS for org-wide posture, Agentshield as the tight runtime guardrail around a production agent.
How Prisma AIRS is deployed, and where Agentshield sits
Deployment model is usually the deciding factor, and it is the part most comparison posts skip. Palo Alto documents two enforcement paths for Prisma AIRS. Network Intercept is an inline security intercept that inspects AI traffic on the network path, which is how a security team gets coverage over applications it does not own or control. API Intercept embeds protection directly in application source, which is how a development team gets it into a specific app. The first is bought and run by the security org; the second needs the app team to integrate.
| Dimension | Prisma AIRS | Agentshield |
|---|---|---|
| Enforcement paths | Network Intercept (inline network) and API Intercept (in source) | In front of the agent action path, framework-neutral |
| Primary unit of protection | AI applications, models, and data across an estate | The individual agent and every tool call it makes |
| Model security | AI Model Security scans models for vulnerabilities before deployment | Not offered; we do not scan model files |
| Red teaming | Automated AI Red Teaming across AI apps and agents | Built-in adversarial runs against your agent |
| Tool and data permissions | Agent identity with RBAC inside the platform | Per-agent least-privilege scope enforced at each tool call |
| Human approval gates | Not the platform focus | Hold payments, deletes, and sends for a person |
| Who has to be involved to start | Security org, and app teams for API Intercept | The developer shipping the agent |
Read that table for fit rather than for a winner. If your problem is that nobody knows how many AI apps exist across the company, Prisma AIRS is aimed squarely at you and Agentshield is not: we do not discover shadow AI across an estate, and we would rather say so than pretend. If your problem is that one production agent holds a payments tool and reads untrusted email, that is our exact job, and a network intercept will not decide whether that specific tool call should have been allowed. For the underlying distinction, see our take on AI agent access control and AI security posture management.
What to actually evaluate when comparing the two
Most head-to-head evaluations get lost in feature-list length, where a platform suite always wins by definition. A more useful test is to take the agent you are shipping and walk it through five questions, then see which product answers them without a caveat.
- Can it block an out-of-policy tool call, not just flag it? Detection that produces an alert after a refund was issued is monitoring, not enforcement. Ask to see a denied action.
- Does the untrusted input get inspected before the agent acts on it? The dangerous text usually arrives mid-task from a retrieved document or a tool result, not from the user prompt.
- Can you require a human on the irreversible actions? Payments, deletes, and external sends need a gate that no prompt can talk its way past.
- Is the audit trail good enough for an auditor? Inputs, policy verdicts, the acting identity, and the approving human, all immutable and exportable. Our AI agent audit requirements guide covers what a defensible record contains.
- How long until it is enforcing in production? Count procurement, integration, and policy authoring honestly, not just install time.
Run that on both. A large enterprise standardizing on Palo Alto will often get acceptable answers from Prisma AIRS plus the platform leverage of one vendor and one console, and that leverage is worth real money. A team that needs question five answered in days rather than quarters will get there faster with a self-serve runtime layer. Both can be the right call; they are just rarely the right call for the same buyer.
Protect AI is now Prisma AIRS, so compare it here
If you came looking for Protect AI alternatives, the company no longer sells a standalone product. Palo Alto Networks announced its intent to acquire Protect AI in April 2025 and completed the deal in July 2025, with the transaction reported at around 700 million dollars. The technology was folded into Prisma AIRS, so a comparison against Protect AI in 2026 is really a comparison against Prisma AIRS, and the buying experience that comes with it.
That matters because the two are not equivalent purchases. Protect AI was an AI security suite you could evaluate on its own terms. Prisma AIRS is a module inside a large platform, which changes pricing, procurement and roadmap in ways a feature table does not show.
| What you are comparing | Protect AI, before the acquisition | Prisma AIRS today |
|---|---|---|
| Core capability | Model scanning, AI supply chain risk, automated red teaming, posture management | The same lineage, extended with Palo Alto runtime protection and posture across the AI estate |
| How you buy it | Standalone, with open-source tooling as an on-ramp | Sales-led, and generally best value if you already buy Palo Alto |
| Open-source projects | ModelScan, NB Defense and Guardian built its developer following | Community projects continue, but the commercial path now runs through the platform |
| Fit for a small team | Approachable, and a genuine reason people liked it | Heavier. This is the gap most people searching for an alternative are actually feeling |
Where we fit is narrower than either. We do not scan model artifacts for backdoors or unsafe serialization, and if importing third-party models is your main risk then Prisma AIRS or HiddenLayer is the correct answer and we are not in the running. We enforce at the moment an agent calls a tool: which tools it may use, which data it may reach, which actions pause for a person, and an audit trail it cannot rewrite. Different control, different point in the stack. The full vendor landscape, including the companies we do not compete with, sits on our AI agent security alternatives page.
Hexadite AIRS and Prisma AIRS are two unrelated products
If you searched for Hexadite AIRS alternatives and landed here, the acronym has sent you sideways. Two different products in two different decades have used the letters AIRS, and only one of them has anything to do with securing AI.
| Hexadite AIRS | Prisma AIRS | |
|---|---|---|
| AIRS stands for | Automated Incident Response Solution | AI Runtime Security |
| What it does | Agentless automated investigation and remediation of security alerts. A SOAR product, built to cut analyst alert volume | Secures AI systems: model scanning, posture, red teaming and runtime protection for AI applications and agents |
| Vendor | Hexadite, based in Boston. Microsoft signed an agreement to acquire it on June 8, 2017, terms undisclosed | Palo Alto Networks. Version 3.0 shipped March 2026 |
| Can you buy it today? | No. The technology was folded into Windows Defender Advanced Threat Protection and ships as the automated investigation and remediation capability in Microsoft Defender | Yes, as part of the Palo Alto Networks platform |
| Relevant to AI agent security? | No. It automates response to security alerts, which is AI applied to your SOC work | Yes. It protects AI systems, which is the opposite direction |
So there is no standalone Hexadite AIRS product to replace. If you are running Microsoft Defender for Endpoint, you already have the descendant of that technology switched on under a different name. The genuine alternatives to it are other security orchestration and automated response platforms, and we are not one of them: we do not triage your alerts or automate your incident response.
If what you actually need is the AI security meaning of AIRS, this page is the right comparison and the rest of it applies. If you came from the Microsoft side and your real question is what a Copilot deployment exposes, the shorter answer sits on our Microsoft 365 Copilot security page, which covers the same distinction between AI that helps your security team and AI that reads your business data. The wider set of name collisions in this market, including several vendors that sound like each other and do unrelated things, is catalogd on the AI agent security alternatives hub.
FAQ
Common questions.
What happened to Protect AI?
Palo Alto Networks announced its intent to acquire Protect AI in April 2025 and completed the acquisition in July 2025, at a figure reported around 700 million dollars. Protect AI no longer sells separately. Its model scanning, supply chain, red teaming and posture capabilities now ship inside Prisma AIRS, which is why anyone shopping for a Protect AI alternative should evaluate Prisma AIRS and the platform it belongs to.
Is Protect AI the same as Prisma AIRS?
Not identical, but Prisma AIRS is where Protect AI ended up. Palo Alto combined the acquired technology with its own AI security work, so the capability lineage carries over while the packaging, pricing and procurement path are those of a Palo Alto platform module. If you liked Protect AI because it was approachable and standalone, that specific quality is the thing that did not survive the acquisition.
What are the Hexadite AIRS alternatives?
First, a disambiguation that trips up most searches. Hexadite was a security orchestration company Microsoft acquired in 2017, and it is unrelated to Prisma AIRS. If you searched Hexadite AIRS alternatives you almost certainly want AI runtime security options, in which case the real comparison set is Prisma AIRS, Lakera, Lasso Security, open source guardrails and us.
How much does Prisma AIRS cost?
Palo Alto Networks does not publish standard Prisma AIRS pricing. It is quote-based and enterprise-led, so you contact sales for a custom quote tied to your usage and platform footprint. Agentshield takes the opposite approach and lists real prices on its pricing page so you can budget without a sales call.
What is Palo Alto Prisma AIRS?
Prisma AIRS is Palo Alto Networks AI Runtime Security, an enterprise suite for securing AI applications and agents. Version 3.0 covers a runtime firewall for prompt injection and data leakage, AI model security, red teaming, agent discovery, agent identity with RBAC, and posture management inside the Palo Alto platform.
Is there a self-serve alternative to Prisma AIRS?
Yes. Agentshield is a self-serve alternative you can deploy in front of an agent in an afternoon, with published pricing instead of a quote. It focuses on runtime agent controls: a prompt-injection firewall, least-privilege tool and data permissions, human-approval gates, monitoring, and an immutable audit trail, across any agent stack.
Does Agentshield replace Prisma AIRS?
For runtime control of an agent that takes actions, yes: Agentshield blocks injection, enforces permissions, gates risky actions, and keeps an audit trail. It is not a like-for-like swap for org-wide AI posture management and shadow-AI discovery across a Palo Alto estate. Match the tool to whether you are securing one agent or a whole company.
How is Prisma AIRS deployed?
Palo Alto documents two enforcement paths. Network Intercept is an inline security intercept that inspects AI traffic on the network path, giving coverage over applications the security team does not own. API Intercept embeds protection into application source code, which needs the app team to integrate it. Which one fits depends on whether the security org or the development team is driving the rollout.
Does Prisma AIRS secure AI agents?
Yes, agent protection is part of the platform, alongside AI application, model, and data security. Palo Alto describes Prisma AIRS 3.0 as adding agent discovery across cloud and SaaS, agent identity with RBAC, and audit trails to its existing runtime firewall, model scanning, and red teaming. The emphasis is estate-wide coverage rather than deep per-agent action control.
What is the best Prisma AIRS alternative for a small team?
For a small team the deciding factors are usually time to enforce and whether pricing is knowable without a sales call. Agentshield is self-serve, stack-neutral, and priced on the page, so one developer can put a runtime firewall, tool permissions, approval gates, and an audit trail in front of a production agent in an afternoon rather than running a procurement cycle.
