Introducing FortressEye

Protect Your Data Before It Leaves Your Browser

FortressEye—The Only True Zero Trust Security for LLMs.

In the last few years, LLMs promised to change how we work. But they came with a quiet risk—confidential data leaking into the cloud, as seen in high-profile incidents like Samsung employees accidentally sharing proprietary code with ChatGPT in 2023[1] or over 370,000 Grok user chats exposed in Google search results in August 2025, revealing sensitive queries on passwords, medical conditions, and personal plans[2]. Compounding this, up to 98% of employees are using Shadow AI tools unsanctioned, according to Varonis' 2025 State of Data Security Report[3]. To "solve" this, legacy security vendors are asking you to make a dangerous trade: "Send us all your employee prompts, and we'll tell you if they're safe." They are centralizing your most sensitive data, breaking the very-first principle of Zero Trust.

FortressEye is built on a different philosophy. A True Zero Trust philosophy.

FortressEye is a silent guardian that runs 100% locally in the browser. It scans, redacts, and rewrites prompts before they can leave. It blocks injections and stops data leaks on-device. No servers. No data sharing. No one sees your prompts. Not us. Not anyone.

That is True Zero Trust. That is real-time LLM protection.

Built for True Zero Trust

Defend against OWASP Top 10 LLM risks[4]—without ever sending your data to the cloud.

Real-Time Input Scanning

Detects and blocks sensitive tokens, PII, and obfuscated injections (OWASP LLM01: Prompt Injection)[4] before they leave the browser—stopping threats like base64-encoded payloads and "Man in the Prompt" attacks instantly.

Redaction & Contextual Rewrite

Automatically redact or transform sensitive content in prompts to prevent disclosures (OWASP LLM02: Sensitive Information Disclosure)[4] while preserving productivity—your team stays efficient without compromising security.

Custom Admin Rules

Create policies by team, role, or domain for governance, mitigating supply chain and poisoning risks (OWASP LLM03: Supply Chain Vulnerabilities / LLM04: Data and Model Poisoning)[4]—giving CISOs the control they need for compliance and risk management.

Full Local Operation

No cloud processing, no training data collection, ensuring zero external exposure and True Zero Trust—your data never leaves the device, eliminating the attack surface entirely.

On-Device AI Engines

Bundled lightweight models for heuristic injection detection and contextual rewrites, defeating advanced attacks like base64 obfuscation without servers—AI-powered security that runs entirely in your browser.
