Secure Your AI Before Someone Else Tests It For You
Your chatbots, copilots, and AI agents are now part of your attack surface. Pentest Testing Corp delivers AI penetration testing built on the OWASP LLM Top 10, uncovering the prompt injection, data leakage, and agent abuse flaws that traditional scanners never see.
Most of the companies we work with aren’t building AI from the ground up. They’re SaaS teams who’ve added a chatbot, wired in an LLM API, or built a copilot on top of their existing product. The integration layer between your AI and your systems is where most vulnerabilities live, and that’s where we focus.
Engagements start from $9,500+. Final pricing depends on the type of AI system, integration depth, the number of exposed LLM APIs and agent tools, and whether adversarial red team testing is included. Every engagement is fixed-price, with no hourly billing and no scope-creep surprises.
Service Overview
What AI Penetration Testing Actually Is
AI penetration testing is the practice of attacking your own AI systems on purpose, under controlled conditions, so real attackers can’t do it first. It goes well beyond checking whether an API responds correctly. We probe how your models reason, what they can be tricked into revealing, and what actions an attacker can force them to take.
Most security tools were built for a web stack: HTTP requests, SQL queries, broken access control. None of that catches a malicious instruction hidden inside a support ticket that your AI assistant reads and obeys. A web application firewall doesn’t understand intent. A vulnerability scanner can’t tell the difference between a user asking a question and an attacker rewriting your system prompt.
Why Businesses Need This Now
AI moved from experiment to production faster than security caught up. Companies are wiring language models into customer support, internal copilots, document search, and autonomous agents that touch real systems and real data. Every one of those integrations is a new way in.
The risk is concrete. An attacker can manipulate a customer-facing chatbot into leaking another customer’s records. A hidden instruction in an uploaded PDF can hijack an AI agent that has email or database access. A poorly scoped copilot can be coaxed into revealing the confidential prompt and business logic behind it.
Auditors have noticed. The OWASP LLM Top 10 is increasingly referenced when validating SOC 2, HIPAA, and similar controls inside AI-enabled systems. An AI security assessment is becoming a baseline expectation, not a nice-to-have. We help you get ahead of it.
What We Test
We test the full range of AI systems that businesses are putting into production. If it makes decisions, answers questions, or acts on your behalf, it’s in scope.
Conversational chatbots and assistants
Customer-facing and internal chatbots, including their guardrails, content filters, and the boundary between user input and system instructions.
LLM APIs and integrations
The endpoints, authentication, rate limiting, and data handling behind your model calls. This is where LLM security testing overlaps with classic API security, and where a lot of damage hides.
RAG applications
Retrieval-augmented generation systems that pull from vector databases and knowledge bases. We look at retrieval poisoning, cross-tenant data exposure, and what happens when untrusted content enters the pipeline.
AI agents and autonomous workflows
Multi-step agents with access to tools, files, and external systems. The more an agent can do, the more an attacker can make it do.
Copilots and embedded assistants
Coding copilots, productivity assistants, and AI features bolted onto existing products, including how they inherit permissions from the host application.
Vision and multimodal models
Image and document processing pipelines, where instructions can be hidden in pixels, metadata, or file structure rather than plain text.
Our Methodology
Our AI red team assessment follows a structured process mapped to the OWASP LLM Top 10 (2025), the most widely referenced framework for large language model security. We don’t run a single tool and hand you a PDF. We work the system the way a determined attacker would, then document everything so your team can act on it.
Phase 1: Scoping and Threat Modeling
We start by understanding what your AI does, what it can access, and who interacts with it. Together we define the attack surface, the assets at risk, and the rules of engagement so testing stays safe and focused.
Phase 2: Reconnaissance and Surface Mapping
We map every entry point: prompts, APIs, file uploads, retrieval sources, connected tools, and agent capabilities. Understanding the full reach of a system is half the work, especially with agents that can chain actions together.
Phase 3: Exploitation and Adversarial Testing
This is the core of the engagement. We attempt prompt injection, system prompt extraction, data exfiltration, jailbreaks, retrieval poisoning, and agent manipulation. Where a vulnerability exists, we prove it with a working proof of concept rather than a theoretical flag.
Phase 4: Impact Analysis
A finding only matters if you understand what it costs you. We trace each vulnerability to its real business impact: data exposed, actions an attacker could trigger, compliance obligations affected, and how far the blast radius extends.
Phase 5: Reporting and Delivery
You receive a clear, prioritized report with reproduction steps, evidence, risk ratings, and specific remediation guidance. We walk your team through it so nothing gets lost in translation.
Phase 6: Retesting and Validation
After you’ve fixed the issues, we verify the fixes actually hold. A finding isn’t closed until we’ve confirmed it.
Vulnerabilities We Find
These are the categories we hunt for in every AI security assessment, aligned with the OWASP LLM Top 10. Each one represents a real way attackers compromise AI systems in production.
Prompt Injection (LLM01)
The top-ranked risk for a reason. Attackers craft input that the model reads as a new instruction instead of data, overriding its intended behavior. We test both direct injection through user prompts and the subtler indirect variety.
Indirect Prompt Injection
Hidden instructions planted in content the AI later processes: a document, a web page, an email, a calendar invite. The user never sees it, but the model obeys it. This is one of the most dangerous and overlooked flaws in agentic systems.
Sensitive Information Disclosure (LLM02)
We test whether your AI can be coaxed into revealing PII, secrets, internal data, or another user’s information through its outputs or traces.
System Prompt Leakage (LLM07)
The instructions, business logic, and guardrails behind your AI are valuable to an attacker. We test whether they can be extracted, then used to bypass your protections.
Insecure LLM API and Output Handling (LLM05)
When downstream systems trust model output without validation, you get injection, code execution, and broken access control wearing a new hat. We test where AI output flows into the rest of your stack.
Excessive Agency and Agent Abuse (LLM06)
Agents often hold more capability, autonomy, or permission than they safely need. We test whether an attacker can push an over-privileged agent into sending messages, modifying data, or invoking tools it shouldn’t.
Vector and Embedding Weaknesses (LLM08)
For RAG systems, we test for poisoned vector stores, cross-tenant data leakage, and manipulated retrieval that quietly corrupts everything the model generates.
Data and Model Poisoning (LLM04)
Where applicable, we assess the integrity of training, fine-tuning, and retrieval data that shapes how your model behaves.
Unbounded Consumption (LLM10)
Uncontrolled resource use that an attacker can weaponize into denial of service or runaway cost. We test the limits, or the lack of them.
Deliverables
When the engagement wraps, you don’t get a vague summary. You get everything your team needs to fix what we found and prove it to anyone who asks.
- Executive summary written for decision-makers, covering overall risk posture and business impact in plain language
- Detailed technical report with every finding, severity rating, affected system, and clear reproduction steps
- Proof-of-concept evidence demonstrating each exploitable vulnerability so there’s no ambiguity about whether it’s real
- Risk-rated findings prioritized so your team knows what to fix first
- Specific remediation guidance mapped to each issue, written to be actionable rather than generic
- OWASP LLM Top 10 mapping showing exactly where you stand against the industry-standard framework
- Remediation walkthrough with your team to answer questions and align on fixes
- Free retest to validate that your fixes actually closed the gaps
Pricing and Scoping
We don’t hide pricing behind a sales call, and we don’t pretend a complex AI system fits a fixed price tag. Both extremes waste your time. Here’s how it actually works.
Every AI penetration testing engagement is fixed-price and scoped to your architecture. You know the number before any work starts, and it doesn’t move unless the scope does. Engagements start from $9,500+, and the final figure depends on a few concrete factors:
- The type and number of AI systems in scope (a single chatbot is very different from a multi-agent platform)
- How deeply the AI is integrated with your APIs, databases, and internal tools
- Whether your system uses RAG, vector databases, or fine-tuned proprietary models
- Whether the engagement includes full adversarial red team testing and training-data review
To keep scoping simple, most clients land in one of three tiers. We’ll confirm exact pricing in your quote.
Not sure where you fit? That’s what the scoping call is for. We’ll recommend the right tier and send a fixed-price proposal within one business day, no sales pressure required.

AI Testing and Your Compliance Program
Auditors are catching up to where your technology already is. SOC 2 trust service criteria around logical access (CC6.1, CC6.6) and change management (CC8.1) increasingly apply to AI systems that touch customer data or make decisions on your behalf. Enterprise customers completing vendor security questionnaires are asking directly about AI security testing, and “we haven’t done it yet” is becoming a harder answer to give.
NIST’s AI Risk Management Framework provides the governance layer, and the OWASP LLM Top 10 is the testing standard auditors and procurement teams are starting to reference by name. We structure our AI penetration testing findings so they map directly to the controls your auditor is already asking about, whether that’s SOC 2, ISO 27001, or a customer’s vendor security review. You get a report your security team can act on and your auditor can file.
