Use AI safely without leaking sensitive data.

Employees already rely on AI tools like ChatGPT, Copilot, and Claude for real work. LogosGuard sits in front of those workflows to detect, warn, block, or auto-redact sensitive data before it leaves your network.

Organizations want AI productivity without exposing sensitive data.

AI adoption is already happening

Training helps, but you still need a technical guardrail. IT teams can't block tools employees already use — they'll just find workarounds. Instead, you need visibility and control.

Data leaks are a real risk

Employees sharing credentials, API keys, customer data, or proprietary code with AI tools exposes your company to breaches, compliance violations, and competitive harm. One mistake can be catastrophic.

Existing solutions don't scale

Network blockers are too blunt. Training alone doesn't stick. You need automated, real-time enforcement that adapts to new tools and workflows.

A private gateway between your employees and external AI.

Real-time redaction and blocking

Detect sensitive data before it's sent. Warn users, block requests, or auto-redact in real time — no false positives, no friction.

Works with tools employees already use

ChatGPT, Claude, Copilot, Gemini, and thousands of other integrations. No need for custom wrappers or workflow changes.

Customizable detection rules

Define what's sensitive for your organization. Keyword patterns, regex, PII detection, custom ML models — your rules, your data.
