AegisGate Lens vs AegisGate Platform

Two products from the same security team, designed for different deployment points. This page explains what each does, when to use which, and when to use them together.

TL;DR

• AegisGate Lens is a free Chrome extension that protects end users browsing AI tools. Browser-level. No account. Privacy-first.
• AegisGate Platform is an enterprise gateway that protects servers and teams running AI tools. Server-level. Per-team pricing. Central policy + analytics.

Use Lens alone if you’re an individual developer, security researcher, journalist, or privacy-conscious user. Use Platform alone if you’re running AI in production at a company and need central policy + audit + compliance. Use both if you want every layer protected (Lens for users, Platform for servers).

Feature-by-Feature Comparison

When to use which

Use Lens alone if:

• You’re an individual developer using AI assistants
• You’re a security researcher analyzing AI behavior
• You’re a journalist or writer concerned about prompt privacy
• You want a privacy-first safety net while you work
• You’re evaluating AegisGate for your team (start with Lens)

Use Platform alone if:

• You’re running AI in production at a company
• You need to enforce AI safety policy across a team
• You need to log AI interactions for compliance
• You need server-side AI protection (your own AI services, not just end-user AI tools)
• You have an SIEM and need alerts

Use both if:

• You want defense in depth: Lens at the user browser + Platform at the server
• You need end-user AI protection AND server-side AI protection
• You’re a security team that needs both behavioral analytics (Platform) and end-user training tools (Lens)
• You want a Lens-detected threat to be promoted to a Platform-wide policy rule (roadmap item T2.2.2)

Technical comparison

Architecture

• Lens: Browser extension (MV3). Content script injected into AI provider pages. Detection runs locally in the browser. Bundle signed with Ed25519, distributed via Chrome Web Store.
• Platform: Self-hosted Docker container (34.7MB). Sits between your AI services and clients. Detection runs in the gateway. Bundle signed with Ed25519, distributed via GitHub Releases.

Detection corpus

Both products share the same detection corpus (the 4-facet taxonomy: PII, secrets, XSS, compliance). When a new threat is added to one, it’s added to the other. 2 more facets (Toxicity, Prompt-Injection) are planned for v0.2.0.

Privacy model
