Open models, hardened against attacks nobody has written yet.

vlno red, our own attack model, generates novel attacks no checklist would catch. Findings become training data that hardens the model, supported by observability, control, and evaluation across your stack.

Open models bring control. The safety team stays behind.

Cost, sovereignty, and customization draw enterprises to open models. The weights arrive without the dedicated safety team and ongoing hardening a frontier lab provides.

No attacker is required.

Agents follow their training, not exactly your intent. Faced with an unusual request, an unexpected document or a situation nobody tested, they can harm you, attacker or not. Rules miss it. vlno red finds it first.

Four capabilities. Start where you need them.

See your agents. Control their actions. Test their resistance. Harden the model. vlno connects all four. Start with one. Add what you need.

  • Observe

    Discover agents, connections, and access.

    Observe

    Know what is running and what it can reach.

    Inventory your agents, their connections, and the resources they can access. See where controls and testing are needed.

    Explore the solutions
  • Control

    Enforce policy and detect misbehavior.

    Control

    Put policy into operation.

    Define and enforce what each agent may do. Verify deployed policy versions and detect misbehavior in real time.

    Explore the solutions
  • Evaluate

    Measure resistance against adaptive attacks.

    Evaluate

    Test whether the agent resists and still delivers.

    vlno red generates novel attacks against real workflows. Compare legitimate and adversarial tasks under the same configuration.

    Measure attack success rate alongside legitimate task completion.

    Explore the solutions
  • Harden

    Strengthen model weights with RL training data or a LoRA adapter.

    Harden

    Change how the model responds under attack.

    Receive RL training data for post-training or a hardening LoRA adapter.

    Teach the model to distinguish genuine instructions from untrusted content. Test resistance and useful performance together. Keep runtime controls in place.
