OPASGUARD · AI SECURITY

Runtime security for the AI your business is already using

OpasGuard sits between your LLM deployments and the outside world — blocking prompt injection, preventing data leaks, enforcing governance policy, and giving auditors the evidence they need.

THE CONTROLS

Six controls, one layer

Deployed as a proxy between your users and your models — no model changes required, one consistent policy across every AI deployment.

Prompt-injection defense

Real-time detection of jailbreak and injection attempts, with configurable modes: log-only, warn, or hard block with a full audit trail.

How it deploys

Data-loss prevention

PII, credentials, and intellectual property blocked from leaving the business through model outputs — configurable per model and per user role.

How it deploys

Policy enforcement

Topical restrictions, response filtering, and role-based access to AI capabilities — enforced consistently across every deployment.

Why it matters

Audit logging

Full, tamper-evident prompt and response logs — exportable for compliance audits, regulatory requests, and internal investigations.

Why it matters

Multi-model coverage

One policy layer across the major commercial and open models, spanning on-premises and SaaS deployments alike.

How it deploys

AI red-team service

Adversarial testing of your AI applications by OpasLabs, with findings fed straight back into your production rules.

THE PROBLEM

Your CEO wants AI. Your CISO wants control.

Most organizations have rolled out assistants and internal models faster than they have governed them. Staff paste sensitive data into prompts, adversaries probe with injection attacks, and auditors ask questions nobody can answer.

OpasGuard closes that gap without slowing anyone down — a single control layer that lets the business adopt AI while security keeps the visibility, enforcement, and evidence it is accountable for.

  • Sensitive data stays inside the business
  • Injection and jailbreak attempts blocked in real time
  • One consistent policy across every model
  • A defensible audit trail for every prompt and response

HOW IT DEPLOYS

From policy to enforced in production

OpasGuard drops in front of your AI without a re-architecture — here is the path from first policy to a governed deployment.

  1. STEP 01

    Discover

    We map the AI already in use across the business — the assistants, copilots, and internal models — and the data flowing through them.

  2. STEP 02

    Define policy

    Together we set the rules: what data can never leave, which topics are restricted, and which roles can use which capabilities.

  3. STEP 03

    Deploy the proxy

    OpasGuard inserts as a proxy between users and models — no model changes, no re-architecture, one layer covering every deployment.

  4. STEP 04

    Enforce & audit

    Injection is blocked, data-loss rules apply in real time, and every prompt and response is logged, tamper-evident, and ready for audit.
