HiddenLayer vs Prisma AIRS for AI supply chain and runtime security
Compare the portfolios, not the whole HiddenLayer platform against one module. Both name supply-chain scanning, adversarial testing, and runtime detection. A module-to-module parity claim was not found.
Palo Alto Networks completed the Protect AI acquisition in July 2025. The current purchasable name is Prisma AIRS. The docs index, updated 21 Sep 2026, lists AI Supply Chain Security, AI Runtime Security, AI Red Teaming, AI Agent Identity, and AI Gateway as capabilities of that platform. AI Model Security is the model-scanning capability inside AI Supply Chain Security, and it is still the title of the model-scanning product page. It is not the whole portfolio.
HiddenLayer sells the HiddenLayer AI Security Platform. The docs index names four modules: AI Discovery, AI Attack Simulation, AI Supply Chain Security (Model Scanner), and AI Runtime Security (AIDR, with Agentic Runtime Security recommended for new work). Prisma AIRS AI Model Security is one capability. Matching every HiddenLayer module to a Prisma module, with the same deployment and the same block behavior, was not found in the docs opened 3 Oct 2026. The shared job both still sell is to scan model artifacts before production and to detect AI threats while applications are in use.

That comment names HiddenLayer and says the company sells security rather than its own models. It does not say HiddenLayer and Prisma AIRS implement the same control.
We reviewed first-party documentation, Prisma AIRS pages, HiddenLayer docs, and live community threads. This compare does not include exploit proofs of concept.

Where each portfolio sits
HiddenLayer is an independent platform with four named modules. Prisma AIRS is Palo Alto’s AI security portfolio, and model scanning sits inside it as AI Model Security. Public docs name similar jobs on both sides. They do not say the modules are equivalent.
| Inventory | AI Discovery: inventory of models, applications, datasets, and dependencies in cloud providers, in production and in development, plus relationships between assets. Discovery can start a model scan | AI Inventory, on the docs index: maps AI workloads, resources, and traffic. A field-by-field match to HiddenLayer AI Discovery was not found in this research |
|---|---|---|
| Model scan | AI Supply Chain Security and Model Scanner. See the next section | AI Model Security inside AI Supply Chain Security. See the next section |
| Adversarial test | AI Attack Simulation: System Prompt Evaluation and Red Team Evaluation, including AutoRT | AI Red Teaming, on the docs index: simulates adversarial attacks. A statement that this is the same test as AutoRT was not found in this research |
| Runtime | AI Runtime Security. AIDR monitors inputs and outputs and can block or redact. The AIDR page says detection does not require access to models or the data that powers them | AI Runtime Security, on the docs index: detects and blocks AI threats in real time at the network or code layer. A shared deployment with AIDR was not found in this research |
| Named only on one side | A module named AI Skill Security was not found on the HiddenLayer docs index. Agentic and MCP protection is named under HiddenLayer runtime | AI Skill Security scans agent skills for prompt manipulation, embedded instructions, tool and MCP use, and related risks. AI Gateway and AI Agent Identity are also named. Equivalents under those names were not found on the HiddenLayer index |
Supply-chain scanning
| What the scan looks for | The supply-chain overview says malware, vulnerabilities, integrity issues, tampering, and backdoors, plus an AI bill of materials and model genealogy. A format count was not found in this research on that overview | The model-security page says 35+ model file types, including PyTorch, ONNX, and TensorFlow, and 25+ threat categories, including embedded malicious code, backdoors, and structural risks. It also names unsafe dependencies, and inspection of architecture, weights, operators, and embedded code |
|---|---|---|
| Where the scan runs | SaaS, or a self-hosted CLI container on servers, cloud, or an air-gapped environment | In the customer environment, so proprietary models stay there. January 2026 notes add Artifactory, GitLab, and cloud storage as sources. API-first CI/CD and MLOps integration is on the same page |
| Policy gate | The supply-chain overview points console workflows for scanning, models, and policy. The rule types were not restated on that overview | The supply-chain doc says rules can be blocking or non-blocking, inside a security group tied to a source such as Hugging Face, local disk, or object storage. A scan records the verdict |
| Threat intelligence named | A WildFire or huntr feed on the HiddenLayer supply-chain overview was not found in this research | Advanced WildFire and the huntr community, with validation results retained for audit |
Those rows are the documented scanner on each side. They are not a claim that the scanners detect the same files or the same threats.
Testing and runtime
| Attack simulation | System Prompt Evaluation and Red Team Evaluation. The index also names adversarial threat simulation, security policy validation, system prompt hardening, and continuous testing | AI Red Teaming on the docs index. The steps, the test types, and whether it covers system prompts were not found in this research on that index page |
|---|---|---|
| Runtime control | AIDR: real-time input and output monitor for hosted or custom LLMs, deployed as container images. It can block or redact. Detection does not require access to the model or its training data. For new work the runtime overview recommends Agentic Runtime Security. AIDR remains supported | AI Runtime Security on the docs index detects and blocks AI threats in real time at the network or code layer. Block, redact, and a no-model-weight deployment were not found in this research on that index page. That is unknown, not a missing control |
| What not to assume | Buying Model Scanner does not, on the docs opened here, include AIDR. The order has to name the module | Buying AI Model Security does not, on the docs opened here, include AI Runtime Security or AI Red Teaming. Those are separate headings |
Where they overlap
Both sell a scan of model artifacts before production, a named adversarial test, and a named runtime detection control. Both are sales-quoted, with no public dollar on the pages opened 3 Oct 2026. Overlap of the job is not parity of the module. An RFP that only says “model scanner” describes AI Model Security and HiddenLayer Model Scanner, and it leaves the rest of each portfolio off the order.
When to use both
Most teams will not run two AI security portfolios. A split that matches the docs is Prisma AIRS for the capabilities on a Palo Alto order, and HiddenLayer for a module Prisma’s pages do not show as the same control. That split is an ownership choice. It is not evidence the products fill each other’s gaps.
Skip Prisma AIRS for this pair if the order you can sign is a HiddenLayer module and you will not buy Prisma AIRS. Skip HiddenLayer for this pair if the order is Prisma AIRS and a second AI security vendor is out of scope. In either case, name the module. Do not compare the HiddenLayer platform with only AI Model Security.
HiddenLayer and Prisma AIRS both still sell model scanning before production and threat detection at runtime. Match a module to a module only where the docs name both, and do not treat silence on one side as a missing control. Then get a quote that names the modules. No public dollar was found on 3 Oct 2026.
FAQs
Are HiddenLayer and Prisma AIRS the same model security product?
No. HiddenLayer sells a four-module AI security platform. AI Model Security is the model scanner inside Prisma AIRS AI Supply Chain Security. Runtime, red teaming, and inventory are other Prisma AIRS capabilities, not that one module.
Is Prisma AIRS a standalone vendor?
Palo Alto Networks completed the Protect AI acquisition in July 2025.
Can the modules be matched one for one?
Both name a model scan, an adversarial test, and runtime detection. The docs do not say those are the same feature. Where a format count, a block action, or a deployment was missing on one side, this page says it was not found.
How is this different from Protect AI vs Lakera?
Protect AI vs Lakera splits model scanning from Lakera Guard runtime prompt screening. This pair stays on the portfolios HiddenLayer and Prisma AIRS still sell, and it does not treat AI Model Security as the whole of Prisma AIRS.
What public prices should buyers note?
On 3 Oct 2026, a public price with currency, unit, period, commitment, and included product was not found for HiddenLayer or for Prisma AIRS. No dollar amount is stated here.
Does this page include exploit how-tos?
No. SecureCoding compare pages do not publish exploit proofs of concept or attack construction steps.
