When to pick Protect AI over Lakera for model vs prompt defense
Choose Protect AI when the job is scanning third-party and proprietary models before they load, now as Prisma AIRS AI Model Security after the Palo Alto acquisition. Choose Lakera when the job is embedding Check Point AI Guardrails (Guard API) so each LLM interaction and agent step is screened for the apps you ship.
AI risk arrives in stages. First a team pulls a Hugging Face or internal model artifact into MLOps. Then the same org ships an app that sends every user prompt and tool call through an LLM. Buying one “AI security” SKU for both stages is how teams still load a pickle payload on Tuesday and miss a prompt injection on Thursday.
Between these two the centers differ. Protect AI capabilities now ship inside Palo Alto Networks Prisma AIRS after the 22 July 2025 close; this page centers Prisma AIRS AI Model Security for in-place model scanning across 35+ formats and 25+ threat categories. Lakera productizes AI Guardrails / Guard API for prompt attacks, data leakage, content violations, malicious links, and off-policy agent behavior on apps and agents you build. Prisma AIRS also markets AI Runtime Security. Lakera also sells agent discovery on a fuller AI Agent Security tier. For Guard versus a GenAI platform across touchpoints see Lakera vs Prompt Security. For workforce network governance versus Prompt Security see WitnessAI vs Prompt Security. More pairs under Compare.
| Job | AI/ML model security: scan third-party and proprietary models for malicious code, backdoors, unsafe dependencies, and supply-chain risk before deploy | Runtime Guard API / AI Guardrails for LLM interactions and agent steps on apps you ship |
|---|---|---|
| How a bad day closes | Block or quarantine a model that fails load-time code execution or policy checks in MLOps / CI | Guard API flags or blocks an adversarial prompt, leaky output, or off-policy tool call under project policy |
| Operator morning unit | Failed model scans, policy violations, approved model inventory | Guard events, project policies, playground tests, agent discovery risk if on full AI Agent Security |
| Deploy | Prisma AIRS AI Model Security in customer environment / MLOps; scans run locally per first-party notes | SaaS or self-hosted Guard API / AI Agent Security; embed calls from app or AI gateway |
| License/pricing | Prisma AIRS / enterprise quote; no public dollar SKU on AI Model Security page (checked 13 Sep 2026) | Free-start messaging on docs plus enterprise quote; SaaS or self-hosted (checked 13 Sep 2026) |
| Who operates it | ML platform / AppSec / AI security owners gating models into the org | AppSec / platform eng embedding Guard on apps and agents they ship |
That is the model-scan morning. If operators still pull untrusted artifacts without a policy gate, Protect AI heritage inside Prisma AIRS AI Model Security is the clearer hire between these two.
We reviewed first-party documentation, pricing pages, product announcements, and live community threads. We did not test the products in paid production environments, so this is not a hands-on benchmark. This page does not include exploit proofs of concept.
Protect AI (Prisma AIRS)
Lakera
Editions and pricing
Ownership and packaging diverge. Protect AI is inside Palo Alto Networks Prisma AIRS. Lakera ships Guard as SaaS or self-hosted under Check Point AI Agent Security branding on docs.
| Owner (2026) | Palo Alto Networks (Protect AI acquisition completed 22 Jul 2025) | Lakera / Check Point AI Agent Security (docs branding) |
|---|---|---|
| How you buy it now | Prisma AIRS modules via Palo Alto sales; confirm AI Model Security on the quote | Free-start on docs for Guard; enterprise for full AI Agent Security or self-hosted |
| Public units | No public dollar SKU on the AI Model Security page checked 13 Sep 2026 | Free-start messaging; enterprise quote for scale (checked 13 Sep 2026) |
| What the invoice covers | Model scanning, policy gates, MLOps integration, WildFire / huntr intelligence per first-party | Guard API projects and policies; optional discovery and risk on full AI Agent Security tier |
| Self-serve start | Datasheet / demo path | Sign up free and call Guard API per quickstart |
If a team needs an API key today to screen prompts, Lakera has the clearer self-serve start between these two. If a team needs model-file policy inside an existing Palo Alto relationship, price Prisma AIRS AI Model Security.
Model scanning and ML supply chain
| Primary surface | In-place model scans for malicious code, architectural backdoors, poisoning, unsafe operators, dependencies, provenance | Not a model-file scanner; Guard evaluates prompts, outputs, and tool traffic at runtime |
|---|---|---|
| When it runs | Selection and predeployment in MLOps / CI, including Artifactory, GitLab, and cloud storage sources per 2026 updates | On each Guard API request from the app or gateway |
| Policy outcome | Allow / block models against org standards before they reach production loaders | Flag or enforce on interaction content and agent tool policy |
| What teams argue about | Whether Prisma AIRS packaging includes the model sources and formats the ML team uses | Whether prompt guardrails replace a model supply-chain gate (they do not, between these two) |
If the painful queue is “can we load this checkpoint,” Protect AI heritage is the clearer hire between these two.
Guard API and runtime defenses
| Primary surface | Prisma AIRS also markets AI Runtime Security; between these two that is not the Protect AI model-scan center | Guard API detectors for prompt attacks, leakage, content, links, dangerous deviation, tool allow/deny |
|---|---|---|
| Integration shape | Model security embeds in MLOps; runtime modules are separate Prisma AIRS capabilities | App or gateway calls Guard per user interaction or agent step; project mode controls enforce vs detect |
| Agent coverage | Prisma AIRS Agent Security is adjacent; confirm on the quote | Tool calls, tool responses, and tool descriptions screened; discovery on fuller AI Agent Security tier |
| What teams argue about | Whether buying Prisma AIRS for models also funds runtime Guard-class coverage without Lakera | Whether Guard alone stops malicious model files at load time (it does not, between these two) |
That is why teams hire an embeddable Guard API they can call on every step. Between these two, Lakera owns that runtime job.
Where they overlap
Both appear on AI security RFPs. Both talk agents and models. Prisma AIRS runtime modules and Lakera Guard can look adjacent in a slideware stack. Overlap is category language. It is not the same weekly queue: gating model artifacts versus screening LLM interactions.
When to use both
Running both can make sense when stages stay funded: Prisma AIRS AI Model Security for model intake, Lakera Guard for app and agent runtime. That is a pipeline split, not two copies of the same firewall.
Skip Lakera for this pair if the only funded job is model scanning inside Prisma AIRS and runtime is already covered by another Guard-class control. Skip Protect AI / model security for this pair if models are fully first-party and trusted, and the only funded job is embedding Guard on apps you ship.
Decide the stage first. If the product must scan models before they load, that is Protect AI heritage inside Prisma AIRS AI Model Security. If the product must screen each LLM interaction on apps you ship, that is Lakera Guard. Only then open the quotes.
FAQs
Are Protect AI and Lakera the same AI security product?
No. Between these two, Protect AI heritage centers on AI model and ML supply-chain scanning inside Prisma AIRS AI Model Security. Lakera centers on Guard API / AI Guardrails that screen LLM interactions and agent steps for apps you ship.
Is Protect AI still a standalone vendor?
Palo Alto Networks completed the Protect AI acquisition on 22 July 2025. Model scanning ships as Prisma AIRS AI Model Security. Ask which Prisma AIRS modules are on the invoice.
Does Lakera only sell Guard?
Docs list AI Agent Security (discovery, risk, runtime) and a standalone AI Guardrails tier. Between these two, the Guard API runtime job is the Lakera center for this pair.
Does either publish list prices?
Lakera docs advertise a free-start path for Guard. Prisma AIRS / Protect AI heritage is sales quoted. No public dollar ladder for either center was listed on the pages checked 13 Sep 2026 beyond that free-start messaging.
Is this a scored bake-off?
No. Order is editorial.
