NexusNest vs Zscaler AI Protect
An honest, feature-by-feature comparison. Zscaler AI Protect is the AI security module of the Zero Trust Exchange - three pillars: AI-SPM (asset inventory), Secure Access to AI, and Secure AI Infrastructure. Designed for enterprises already running Zscaler SASE.
| Capability | NexusNest | Zscaler AI Protect |
|---|---|---|
Architecture | Purpose-built for AI traffic. Two focused products (PromptWall + NetLens). Lightweight device agent | Full SASE platform - SWG + CASB + ZTNA + DLP. AI Security Suite (launched Jan 2026) is one module on the Zero Trust Exchange |
Where redaction happens | In-flight, before the request reaches the AI provider - only AI traffic is routed for redaction, and originals are never stored | In Zscaler's cloud PoP after the Client Connector forwards traffic - every flow makes the round-trip |
AI detection | Hybrid detection - fast deterministic patterns plus contextual AI for the harder cases | LLM Classification + 500+ pre-built sensitive info types |
AI tool coverage | Major AI tools out of the box, with admin-added schemas for custom or internal tools | Sanctioned AI services: ChatGPT, Claude, Copilot, Gemini, AWS Bedrock |
Limitations on prompt inspection | Whatever the agent intercepts is redacted - no SSE detour required | Only protects traffic routed through ZIA. Doesn't govern locally-running LLMs without an agent |
Latency overhead | Negligible on most prompts; contextual detection adds a short delay only on flagged content | Adds measurable latency from the cloud inspection round-trip on every flow |
Self-serve | yes - sign up, download, deploy in 30 minutes | no - enterprise SASE sales motion. Weeks-to-months rollout |
Pricing | ₹999–1,999/seat/month. Published. Credit-card checkout | Bundled inside the Zscaler stack; contracts typically ₹50L+ (~$60K+/year) |
Best fit | Mid-market (50–300 employees) adopting AI tools fast | Large enterprises (1000+ employees) already standardised on Zscaler SASE |
Pick NexusNest if
You're mid-market and need AI DLP without buying the full SASE platform. You want focused AI redaction so the AI provider only ever receives the redacted prompt, with originals never stored. You want transparent per-seat pricing and a 30-minute deploy.
Pick Zscaler AI Protect if
You're a large enterprise already on Zscaler ZIA / ZPA and want AI Security as one more module in the same console. You're comfortable with the SSL decrypt-and-re-encrypt model.
