Salus vs Snyk
Updated March 27, 2026
Overview
Runtime guardrails API that validates AI agent actions against policies before execution, blocking incorrect actions with structured feedback.
Snyk is the developer-first security platform with deep AI security capabilities. Snyk for AI (evolved from DeepCode) scans code, dependencies, containers, and infrastructure-as-code for AI-specific vulnerabilities. Developers use Snyk to detect insecure model loading, prompt injection risks, and vulnerable ML library dependencies directly in their IDE and CI/CD pipelines. The most widely adopted security tool among AI developers.
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
- 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
Pros
- Developer-friendly with seamless IDE and CI/CD integration for shift-left security
- Extensive and continuously updated vulnerability database ensures early threat detection
- Comprehensive coverage across code, containers, IaC, and open-source dependencies
- Strong AI security capabilities specifically designed for ML/AI development workflows
Cons
- Frequent false positives can create alert fatigue and slow down development
- Poor customer support with slow response times during critical security issues
- Scans can take several minutes for medium-sized repositories, slowing CI/CD pipelines
- Documentation quality inconsistent, making troubleshooting and configuration difficult
