Snyk Evo Discovery vs Zscaler SPLX: Side-by-Side Comparison (2026)

Short answer

Security and platform engineering leaders managing AI-heavy codebases need Snyk Evo Discovery because it's the only free tool that actually inventories what's already running in your repos,AI models, agents, datasets, and plugins,before you can govern it. The local scanning model means no code leaves your environment, and the API access lets you wire discovery into existing CI/CD gates without rip-and-replace. Skip this if your organization hasn't yet adopted LLMs or agentic workflows at scale; you're paying attention too early. Enterprise security teams deploying large language models in production will find value in Zscaler SPLX because it combines runtime input guardrails with automated red teaming, catching both prompt injection attacks and drift in model behavior that traditional security tools miss. The platform maps to six NIST CSF 2.0 functions across asset discovery, continuous monitoring, and supply chain risk, with particular strength in the Adverse Event Analysis phase through real-time LLM log inspection. This tool is overkill for teams still piloting single LLM applications or those primarily concerned with third-party model risk; it's built for organizations managing agentic workflows and internal model customization at scale.
