Protect AI vs Salus
Updated March 27, 2026
Overview
Protect AI provides end-to-end AI/ML security covering the entire model lifecycle. Its platform includes model scanning for vulnerabilities, supply-chain security for ML artifacts, runtime threat detection, and policy enforcement. Protect AI helps enterprises secure AI pipelines from development through production deployment.
Runtime guardrails API that validates AI agent actions against policies before execution, blocking incorrect actions with structured feedback.
Key features
Core capabilities each platform advertises.
- Runtime action validation
- Policy-based guardrails
- Pre-execution blocking
- Structured feedback for self-correction
- Agent action auditing
Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Comprehensive security coverage across the entire AI/ML lifecycle
- Specialized focus on AI-specific threats and vulnerabilities
- Enterprise-grade features including supply-chain security and policy enforcement
- Strong runtime threat detection capabilities
Cons
- No public pricing makes budget planning difficult
- Enterprise-only model may not be accessible for smaller teams
- Requires consultation with sales team for quotes, adding friction to evaluation
- Custom pricing based on deployment scale can lead to unpredictable costs as AI usage grows
Pros
- Solves a critical problem — agents executing incorrect actions can cost enterprises thousands per incident
- Clean developer experience with Python SDK, decorator-based instrumentation, and framework-agnostic compatibility
- 58% self-recovery rate on blocked actions means agents keep working rather than failing hard
- Comprehensive approach combining runtime guardrails, observability, and pre-deployment adversarial evals
- Well-funded at .7M with strong Stanford CS founding team
Cons
- No public pricing creates friction for developer adoption in a space with transparent free tiers
- Very early stage (founded 2026) with a small team and limited enterprise track record
- Competes with Guardrails AI and built-in safety features from OpenAI and Anthropic
- Adding a validation layer introduces latency to every agent action
