AI Model Firewall/Security Layer

A security product that acts as a firewall for self-hosted AI models, protecting against prompt injection, data leakage, and unauthorized access. As companies move to hosting open-source models, they need security guardrails.

Enterprise adoption of open-source models like Llama and Mistral is accelerating fast, and security tooling is lagging badly — most teams are duct-taping together custom filters or ignoring the problem entirely. Protect AI and Lakera Guard are the closest incumbents, so the space has early players but no dominant standard yet, which means there's still room to establish a position. The $5k–20k/mo revenue band is conservative given that security buyers at mid-market and enterprise companies typically have budget for this category and will pay on annual contracts, so ceiling is probably higher if you can get past the procurement gatekeepers. The biggest risk is that the major inference serving frameworks — vLLM, Ollama, and cloud providers — bake basic guardrails directly into their stacks, commoditizing the core feature before you can build enough switching cost around it.
