NexusNest vs Lakera Guard
An honest, feature-by-feature comparison. An AI application firewall - sits between users and the LLM in apps you build to catch prompt injection, jailbreaks, and content abuse. Acquired by Check Point in September 2025.
| Capability | NexusNest | Lakera Guard |
|---|---|---|
What it protects | Employees and the data they paste into third-party AI tools | AI applications you build - protects them from prompt injection, jailbreaks, and abuse at the API layer |
Who installs it | IT / security admins. Employees never integrate anything | Developers building AI features. Must add the SDK / API call into application code |
Where it runs | On every employee laptop as a lightweight agent | Inside your AI application, as a middleware between user input and the LLM |
Use case overlap | Stops PII / credentials being pasted into ChatGPT, Claude, Cursor, Copilot, Gemini | Stops prompt injection and content abuse inside the AI app you ship to customers |
Coverage | All outbound AI traffic from the device | Only the application(s) where the developer integrates the API |
Network monitoring | NetLens - full HTTP/HTTPS metadata, per-employee views | None - Lakera scans payloads, not network traffic |
Detection accuracy claims | Hybrid detection tuned per tenant | 98%+ on prompt injection; sub-50 ms average latency; 100+ languages |
Self-hosted option | Yes | yes - container for on-prem / private cloud |
Pricing | ₹999–1,999/seat/month. Published | Free Community tier, Pro from $99/mo, Enterprise custom |
Post-acquisition status | Independent startup | Acquired by Check Point (~$300M, September 2025). Now part of Check Point Infinity |
Pick NexusNest if
Your concern is what employees paste into third-party AI tools (ChatGPT, Claude, Cursor). You want IT-managed governance, not developer integration.
Pick Lakera Guard if
You're building an AI feature into your own product and need to defend it against prompt injection, jailbreaks, and content abuse. Developer-managed, integrated via API.
