Runtime security
for enterprise AI.
Your CEO wants AI. Your CISO wants control. OpasGuard sits between your LLM deployments and the outside world - blocking prompt injection, preventing data leaks, enforcing governance policies, and giving auditors what they need.
The problem
Enterprise AI is being deployed faster than it's being secured.
Most organizations have deployed ChatGPT, Copilot, or internal LLMs with minimal governance. Employees are pasting sensitive data into prompts. Adversaries are probing with injection attacks. Auditors are asking questions nobody can answer. OpasGuard closes the gap.
What OpasGuard does
Six controls. One layer.
Deployed as a proxy between your users and your LLMs - no model changes required.
Prompt Injection Defense
Real-time detection of jailbreak and injection attempts. Configurable blocking modes: log-only, warn, or hard block with audit trail.
Data Loss Prevention
PII, PHI, credentials, and IP blocked from leaving the enterprise via LLM outputs. Configurable per model and per user role.
Policy Enforcement
Topical restrictions, response filtering, and role-based access to LLM capabilities. Enforced consistently across all enterprise AI deployments.
Audit Logging
Full prompt + response logs. Tamper-evident. Exportable for compliance audits, regulatory requests, and internal investigations.
Multi-Model Coverage
