Enough for a small web application and its API, free retest included. Need more coverage? Buy more credits and spend them across web, API, mobile, cloud and network as priorities change; unused credits roll over quarterly. Continuous PTaaS subscriptions are quoted on scope.

You set the budget. We fit the scope.

Working to a fixed number? Tell us what it is. We scope a timeboxed test to fit it and agree what gets tested first, so you get the most coverage your budget allows — in writing, before testing starts.

WHY ioSENTRIX

Why teams choose ioSENTRIX for AI security

Attacker-led testing of your LLM apps and agents, mapped to the standards auditors cite — plus validation that your AI controls hold.

  • Attacker-led, not a checklistWe attack your AI the way a real adversary would — prompt injection, jailbreaks, tool and agent abuse, insecure output handling — and prove each finding, not just flag it.
  • Mapped to the AI standards that matterFindings map to the OWASP LLM Top 10, OWASP Agentic, MITRE ATLAS and NIST AI RMF — the frameworks your auditors and customers are starting to ask about.
  • Control validation, with synthetic dataBeyond pen testing the app, we validate whether your AI-use policies hold — can sensitive data reach public AI? — using uniquely-marked synthetic data across every path, so your real data is never touched.

The AI question

An AI tool isn't a pentest — it's a faster scanner

The tool was never the hard part. Years ago the choice was the same: run Burp Suite yourself, or hire a firm that also runs Burp. The scanner didn't make the difference — the person driving it did. AI hasn't changed that. It's changed the speed.

AI is genuinely good at breadth — known vulnerabilities, routine coverage, pattern-matching at scale — so we run it on every engagement to go faster and wider. But the flaws that actually get companies breached are business-logic abuse, broken authorization, and weaknesses chained into real impact — the things an autonomous tool still can't reason about.

9%
of security leaders trust automation on its own in 2026 — down from 29% a year earlier
78%
have been hit by critical false negatives from fully automated scanning

— 2026 survey of 455 security leaders

So we use AI too — then our OSCP-certified engineers do what AI can't: understand your business, chain the findings, and prove what's actually exploitable. AI makes us faster. Skill is what makes it a pentest.

Before you ask

Questions buyers ask before they book

What is AI penetration testing?

AI penetration testing is an authorized attack on your AI and LLM systems — applications, agents, RAG pipelines and the models behind them. Engineers test for prompt injection, jailbreaks, tool and agent abuse, insecure output handling, and model and data leakage, and prove each finding with a working example.

How much does penetration testing cost with ioSENTRIX?

Engagements start at $6,400 — 40 credits at $160 each — covering a focused LLM application test with a free retest. Agentic systems and multi-model pipelines use more credits, and unused credits roll over quarterly. Every quote is a fixed price in writing after a 15-minute scoping call.

What AI systems do you test?

LLM-powered applications and chatbots, autonomous and multi-agent systems, RAG and vector-search pipelines, model APIs and fine-tuned models, and the integrations and tools your agents can call.

Which AI standards do you map to?

The OWASP Top 10 for LLM Applications, OWASP Agentic security guidance, MITRE ATLAS, and the NIST AI Risk Management Framework (AI RMF) — so your findings line up with what auditors and enterprise customers reference.

What is AI control validation?

Separate from testing an AI app, control validation checks whether your AI-use policy actually holds — for example, whether an employee can get customer data into a public AI tool. We test every path (paste, upload, browser, API) with uniquely-marked synthetic data, so your real data is never touched.

Is our data safe during testing?

Yes. We test with synthetic, uniquely-marked records — never your real PII, PHI, secrets or source code. Your data never leaves your environment or reaches ours.

How long does an AI penetration test take?

A focused LLM application test takes 1–3 weeks including reporting; agentic systems and multi-model pipelines take longer. Free retesting confirms your fixes.

Ready when you are

Test your AI before an attacker does

Tell us what AI you've shipped — apps, agents or pipelines — and we'll scope a test mapped to the standards that matter. No commitment, no sales call before the engineer call.
