AI SECURITY VALIDATON

Validate the security controls protecting your AI

Picus fires real prompt injections, jailbreaks, and tool-abuse attacks at the controls protecting your AI, then shows you per attack what each one blocked, refused, or let reach the model.

THE BASICS

What is AI Security Validation?

AI Security Validation is the practice of testing whether the controls protecting your AI applications, agents, and LLM deployments actually block the adversarial inputs attackers send.

It connects to your AI system as a target, then sends real prompt injections, jailbreaks, data-leakage attempts, and agent and tool-abuse attacks at the deployed guardrail, and reads back per input whether the control blocked, refused, or let it through before the model acted.

Rather than assuming a content filter or safety policy works because it is switched on, you get evidence of what the control actually stops, scored against the frameworks your program already reports on.

Why Validate your AI Controls?

  • Prove your guardrails hold against the techniques adversaries use now
  • Catch the default or loosened settings that quietly leave the model exposed
  • Validate the control you deployed, not the foundation model's training
  • Cover agent, plugin, and MCP tool abuse, not just chat prompts
  • Re-validate the moment a new jailbreak or injection technique appears
the problem

Your business shipped AI faster than anyone can prove it is safe.

Shipped on defaults

Controls you never tuned

Prompt-injection filters, gateways, and safety policies arrive on default settings and rarely get tuned to your application. Turning one on feels like the risk is handled, but a deployed control is not a validated one.

Techniques move daily

Yesterday's filter, today's bypass

New jailbreak, injection, and agent-abuse methods appear all the time. A control that refused last month's attack may quietly pass this week's, and nothing tells you it started failing.

No evidence

Nothing to show leadership

When the board asks whether AI initiatives are secured, the honest answer rests on assumptions and policy documents, not evidence of what the control in front of the model actually stops.

The real question is not whether the base model is safe out of the box. It is whether your controls ever let the adversarial input reach the model at all.

Why Now · The Post-Mythos Era

AI changes faster than manual validation can keep up.

Prompts, policies, models, agents, and connectors change constantly, and guardrails can degrade without teams noticing until something breaks. The model built for a slower review cycle, approve a control once and assume it holds, quietly fails against an environment that changes every day.

The Solution

Put your AI controls under real attack, then see what they actually stopped.

Picus connects to your AI application, agent, or guardrail as a target, sends real adversarial inputs at it, and <b>shows you which attacks the control blocked, refused, or let reach the model.

It uses an agentless, API-based approach to stress-test your AI endpoints directly, and it tests the control you deployed rather than the foundation model's training, so you move from assuming the guardrail holds to knowing whether it does.

Prompt Injection & Leakage

See exactly which adversarial inputs your control stops.

Send direct and indirect prompt-injection and data-leakage payloads at your AI target and validate, per input, whether the control blocked, refused, or let it through before the model acted. No more inferring coverage from the fact that a filter is switched on.

Jailbreak Resistance

Prove your controls hold against real jailbreaks.

Attempt known and obfuscated jailbreaks, including role-play framing, encoding, and multi-step escalation, against your controls to prove they hold, instead of assuming the model refuses on its own. Attacks run context-aware, adapting to each target's purpose and boundaries.

Powered by the Picus Threat Library and AI Threat Builder, which turns fresh threat intel into runnable, framework-mapped AI attack simulations.
Agent, Tool & MCP Abuse

Test the agents and tools, not just the chat box.

Validate whether agents can invoke tools beyond intended scope, whether MCP servers and connectors create new trust-boundary weaknesses, and whether tool use stays constrained by least privilege. This is where the highest-severity AI risk now lives.

Powered by the Picus Attack Library, with critical-severity coverage of agentic and MCP abuse: privilege escalation, credential compromise, lateral movement, remote code execution, and data exfiltration.

how it works

Connect a target, run the attacks, read the verdict.

Picus uses an agentless, API-based approach to stress-test your AI endpoints directly, then runs the validate, fix, re-validate loop continuously.

  1. Step 1:
    Target Setup
    Connect

    Add your AI system as a target with its endpoint and authentication. Import the request from cURL, handle stateless or session-based flows, and set purpose and boundaries.

  2. Step 2:
    Attack Library
    Simulate

    Pick from 70+ attacks and 39 standards-based playbooks, or import your own. Attacks run context-aware, adapting to the target's purpose, as instant or scheduled simulations.

  3. Step 3:
    Hybrid Verdict Engine
    Validate

    A hybrid engine of fixed rules and an AI judge returns a clear verdict per input: blocked, not blocked, or not tested, with the evidence behind each one.

  4. Step 4:
    Framework Mapping
    Prove

    Results map to MITRE ATLAS, OWASP LLM Top 10, and NIST AI RMF, showing which attack classes reached the model and where defaults left it exposed. Export to CSV.

  5. Step 5:
    Picus Swarm
    Re-validate

    Re-run the same inputs after a fix to prove the gap closed, and re-run on signal when a new jailbreak or injection technique appears.

The loop runs continuously. A control that passed last month is re-validated against this week's attacks, so coverage stays current instead of decaying between reviews.

Real Targets

Validate the AI controls you actually run.

Picus connects to your live AI applications, agents, and the commercial guardrails and gateways in front of them, then tests each one directly. You validate your deployment and your configuration, not a benchmark of someone else's model.

What Sets Picus Apart

Evidence about the control you own, not a test of the model.

  • Validates the control, not the model

    Picus tests the deployed guardrail, gateway, and policy enforcement in front of your AI, not the foundation model's training or alignment, so you get evidence about the part you actually control and can change.

  • A repeatable loop, not a one-time red team

    Powered by Picus Swarm, validation re-runs the moment a new jailbreak or injection technique appears, so AI coverage is an ongoing measure of effectiveness rather than a point-in-time snapshot.

  • Real coverage, not just chat prompts

    70+ attacks and 39 playbooks span prompt injection, jailbreaks, data leakage, harmful content, and critical-severity agent and MCP tool abuse, mapped to three named frameworks.

  • One control surface in a converged platform

    Your AI guardrails are validated alongside network, endpoint, and email controls in the same platform and the same loop, feeding one answer: validate, decide, fix, and re-validate.

The Picus Platform

One platform validates your whole security program.

AI Security Validation is one capability of the Picus Platform. Picus converges breach and attack simulation, autonomous penetration testing, and exposure validation into one continuous validation loop, from attack surface to controls to exploitable exposures.

Breach and Attack Simulation
Continuously tests what your EDR, SIEM, firewall, WAF, and other security controls actually block and detect against the newest attacker techniques, then ships the fixes and re-validates that the gap closed.
Autonomous Pentesting
Executes real exploit chains in your environment, showing what an attacker can actually reach and do, not what a CVSS or EPSS score predicts. Live validation, run safely in production.
Exposure Validation
Proves exploitability without firing an exploit, covering the restricted assets no live test can touch and the CVEs with no public or safe exploit, for a defensible verdict on day one of disclosure.

Frequently Asked Questions about AI Security Validation

AI Security Validation is the practice of testing whether the controls protecting your AI applications, agents, and LLM deployments actually block the adversarial inputs attackers send. It connects to your AI system as a target, sends real prompt injections, jailbreaks, data-leakage attempts, and tool-abuse attacks at your deployed control, and reads back whether each one was blocked, refused, or reached the model.

AI red teaming and AI penetration tests are usually one-time, offensive engagements that probe a model's inherent behavior. AI Security Validation is a repeatable control-validation loop. It tests whether your deployed control catches a given attack and re-runs as new techniques appear, inside the same platform that validates your network, endpoint, and email controls, so the result is an ongoing measure of effectiveness rather than a point-in-time snapshot.

It ships 70+ attacks across five categories: prompt injection, jailbreaks, leakage, exploitation, and harmful content generation. That includes direct and indirect prompt injection, known and obfuscated jailbreaks, system-prompt and PII leakage, and critical-severity agent and MCP tool abuse such as privilege escalation, credential compromise, lateral movement, and remote code execution. You can also import your own attacks.

The controls around it. Picus validates the deployed guardrail, gateway, and policy enforcement protecting your AI, not the foundation model's training or alignment. The base model's inherent safety is the model vendor's responsibility. Your control is what stands between an adversarial input and the model, and that is what AI Security Validation proves.

Picus connects to internal AI applications, agents, and LLM deployments, as well as the commercial guardrails and gateways in front of them, using an agentless, API-based approach. It handles both stateless endpoints and session-based flows, and supports API key, Bearer, and Basic authentication so it can reach protected endpoints securely.

Yes. Picus runs adversarial inputs against the controls around your specific AI application, agent, or LLM and reads back how each input was handled, so the result reflects your deployment and your configuration rather than a generic model. Attacks run context-aware, adapting to the target's stated purpose and boundaries.

Whenever something changes that could affect the answer: a new jailbreak or injection technique, a model or guardrail update, or a policy change. Because new techniques surface constantly, Picus runs validation as a signal-driven loop rather than on a fixed calendar, so a control that passed last month is re-validated against this week's attacks.

Every result maps automatically to MITRE ATLAS, OWASP LLM Top 10, and NIST AI RMF, and the platform ships standards-aligned playbooks for each. You get a live coverage view per framework and exportable, audit-ready evidence you can take to leadership.

Picus runs adversarial inputs against a designated, scoped AI target or controlled endpoint you define, reads back how the control handled each input, and reports a verdict without persisting injected content.
