About
See everything. Protect what matters.
NexusNest is the control and governance layer for AI, built for teams who can't afford to slow their employees down. We redact sensitive data in every prompt to ChatGPT, Claude, Copilot, Gemini, Cursor, Perplexity and Grok, before it reaches the AI provider.
Why we built this
Every security team has the same week: an employee pastes a customer record into ChatGPT, an engineer pastes a config file into Claude, a support agent pastes a full transcript into Gemini. The exposure has already happened by the time anyone notices.
Existing controls watch email, USB drives and SaaS uploads. None of them were built for the prompt box, and a browser-only approach misses the desktop apps and IDE assistants people actually use.
NexusNest is a single device-level agent that catches outbound AI traffic regardless of where it originated, browser, desktop app, IDE plugin, CLI tool, and redacts sensitive content before it reaches the AI provider. The employee gets the answer they wanted. The data they shouldn't have shared never goes upstream.
What we believe
Redacted before the AI provider ever sees it
Every prompt is redacted in flight, before it reaches the AI provider. The model only ever receives the redacted version. Originals are discarded the moment the redacted version is computed, and there is no reverse mapping back to them.
Visibility without reading anyone's prompts
NetLens builds its usage view from redacted text only, never from the original prompt. Admins see how AI is used across the company without anyone's raw content passing through a dashboard.
Ship in minutes, not quarters
A single agent install covers browsers, desktop apps, IDE assistants and CLI tools. No rollout workshop, no policy authoring project. Teams are covered the same day they decide to be.
The team
NexusNest is built in India for global teams. We're a small, founder-led group with backgrounds in security engineering, distributed systems and product design.

What we're working on
- PromptWall, the redaction layer. Intercepts AI requests, redacts sensitive fields, and forwards a clean prompt upstream.
- NetLens, the visibility layer. Shows which AI tools employees use, what got redacted, and gives admins an audit trail.
- Self-hosted and in-VPC deployment paths for regulated buyers in banking, healthcare and the public sector. Talk to us if that shape fits.
