Top Protect AI (Palo Alto Networks) Alternatives for 2026
Protect AI (Palo Alto Networks) focuses on mlsecops & supply chain. Now part of Palo Alto Networks, many teams evaluate alternatives for broader agent coverage, different deployment models, or pricing that fits their scale. Here are the top competitors to consider.

What is Protect AI (Palo Alto Networks)?
Protect AI defined the MLSecOps category: model artifact scanning (ModelScan, Guardian), an AI bill of materials, LLM runtime protection, and the huntr AI/ML bug-bounty community. Palo Alto Networks acquired it in July 2025 and integrated it natively into Prisma AIRS — version 3.0, launched March 2026, extends the platform to agentic AI security. The open-source tools (ModelScan, LLM Guard, Rebuff) remain maintained under the Protect AI GitHub organization.
Why teams look for Protect AI (Palo Alto Networks) alternatives
Prisma AIRS is a platform-scale commitment: pricing and packaging target Palo Alto's enterprise base, and the model-supply-chain heritage means agent-runtime controls are newer than the scanning core. Teams that only need one slice — supply-chain scanning, or runtime guardrails — can often get it faster from a focused vendor or the open-source tools themselves.
GuardionAI
Where Prisma AIRS approaches AI security from the model-artifact and posture side, GuardionAI starts at the action layer: inline governance of live agent behavior with sub-130ms policy decisions, deployable without a Palo Alto platform relationship.
Why it's better than Protect AI (Palo Alto Networks)
sub-130ms guardrails latency • 96.3 F1 on the Prompt Security Leaderboard with 0.02% false positives • 50M+ agent actions protected per month
Wiz (AI-SPM)
Wiz AI-SPM extends its agentless CNAPP to discover every AI asset via an AI-BOM, covering Bedrock, Azure OpenAI, Vertex AI, and self-hosted models. In 2025–26 it added runtime monitoring for rogue agents, prompt injection, and behavioral drift, with attack-path analysis connecting AI misconfigurations to sensitive training data via DSPM.
- Agentless AI-BOM discovery including shadow AI across clouds
- Attack-path context links AI risk to data exposure
Palo Alto Networks (Prisma AIRS)
Integrated AI security platform providing visibility across the AI lifecycle, from development to production, ensuring compliant and secure model usage.
- Deep integration with PA stack
- Comprehensive lifecycle coverage
Apiiro
Force-multiplies AppSec teams to design and deliver secure software, now with Agentic AI focus.
Protect AI (Palo Alto Networks) is a good fit for…
- •Palo Alto Networks customers consolidating on Prisma
- •Organizations with heavy model supply-chain risk (fine-tuning, model zoos)
- •Teams that want scanning, posture, and runtime from one vendor
Look at alternatives if…
- •Small teams needing just runtime guardrails
- •Buyers avoiding large-platform lock-in
Our verdict
The most complete model-supply-chain story on the market, now with Palo Alto scale. Evaluate focused runtime platforms alongside it if live agent behavior is your primary risk.
