NexusNest Reviews & Product Details

What is NexusNest? NexusNest is an AI Data Loss Prevention (AI DLP) platform that stops sensitive data from leaving your laptop when your team uses generative AI tools. It masks things like customer names, emails, phone numbers, API keys, passwords, financial records, health data, and source code before prompts reach ChatGPT, Claude, GitHub Copilot, Google Gemini, Cursor, Perplexity, or Grok. The AI still answers the question — it just never sees the sensitive parts. Why it matters Every security team has watched it happen: - Someone pastes a customer record into ChatGPT. - An engineer pastes a .env file into Claude. - A support agent pastes a full ticket into Gemini. - A founder pastes a draft contract into ChatGPT to "make it sharper." The leak is over before anyone notices. Classic DLP (Symantec, Forcepoint, McAfee) wasn't built for the prompt box. Browser extensions miss desktop apps, IDE assistants, and terminal calls. Network DLP and SASE rollouts take two quarters and a six-figure check. Meanwhile, shadow AI — every AI tool your employees signed up for without IT knowing — keeps growing. Cyber insurance underwriters now ask about AI usage visibility on renewals. Regulators (DPDP in India, GDPR in the EU, HIPAA in the US) treat customer data sent to a third-party AI provider as a cross-border transfer. What we built One agent. Installs on the laptop. Covers every AI tool — browser, desktop, IDE, terminal. The agent runs as a local HTTPS proxy with a per-machine trusted CA, intercepts AI traffic on the wire, sends prompt text to a tenant-isolated masking service, and rewrites the prompt with placeholders like [MASKED_CREDENTIALS_1] before the request reaches the AI provider. The masking happens on the device boundary, not in someone else's cloud. There is no second processor in the data path — the sensitive content never leaves the employee's machine. That's the entire pitch: stop the leak where it starts, not at the network edge after it has already crossed the boundary. Coverage ChatGPT (web + desktop) · Claude (web + desktop + Claude Code) · GitHub Copilot (VS Code + JetBrains) · Google Gemini (web + Workspace) · Cursor (agent mode + Cmd-K) · Perplexity (including Comet browser) · Grok (inside X) · OpenAI / Anthropic / Google APIs from terminal scripts · any AI tool that speaks HTTPS. How NexusNest is different - On-device masking vs cloud-routed redaction (no second processor in your data path) - Endpoint agent vs browser extension (catches Claude desktop, Cursor, terminal-based AI) - Pay-per-seat per-month vs enterprise-quote-only contracts (₹499/seat starter, no minimum commit) - Live in 10 minutes vs months-long SASE rollouts Built for CISOs, security engineers, IT leads, compliance officers, and founder-CTOs at 10-to-2000-person companies who want to let their team use AI productively without losing control of what gets pasted into the prompt box. Particularly fits regulated sectors — fintech, healthtech, legaltech, SaaS handling EU/India customer data — and any company shipping software where source code or unreleased product codenames must not leak to public LLMs. Getting started Two clicks per laptop.
