AI adoption is already happening
Employees already use external LLMs daily. Policy alone will not stop mistakes.
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.
Backed by
Prompt Gateway
Stop accidental leakage in real time.
Scan prompts and files locally. Enforce policy before anything reaches external providers.

The Problem
Organizations want AI productivity without exposing regulated data.
Training helps, but you still need a technical guardrail and an audit trail.
Sensitive data leakage is the core risk
Prompts can include PII/PHI, MNPI, customer data, HR/legal docs, code, and credentials.
Firewall blocks are not a long-term answer
Blanket blocks kill productivity and drive shadow usage. Teams need guardrails plus audit logs.
What LogosGuard Does
A private gateway between your employees and external models.
