AI & LLM Security Testing
AI is now part of your attack surface. Large language models, AI agents and autonomous workflows introduce risks that traditional testing was never designed to find — prompt injection, insecure tool use, training-data and prompt leakage, and unsafe automation that can act on a user’s behalf. Aesparrow’s AI & LLM Security Testing assesses your AI-powered features the way a real adversary would, aligned to the OWASP Top 10 for LLM Applications and the NIST AI Risk Management Framework.
We test the whole AI stack: the model and its prompts, the retrieval and tool-calling layer, the APIs around it, and the guardrails meant to keep it safe. We attempt prompt injection and jailbreaks, probe for sensitive-data exposure, test whether an agent can be manipulated into unsafe actions, and check the classic application and API security of everything supporting it. You get verified findings, business-impact ratings and clear remediation — plus a free re-test once you have fixed them.
AI & LLM Security Testing — done right, the first time.
Senior practitioners. Verified findings. Free re-test.
Overview
AI & LLM Security Testing is an authorised assessment of your AI-powered features and the systems around them. Because AI introduces new, non-deterministic failure modes, we combine adversarial prompt testing with classic application and API security to give you a complete picture of AI risk.
What we test for
Aligned to the OWASP Top 10 for LLM Applications and NIST AI RMF.
- Prompt injection & jailbreaks — direct and indirect manipulation of model behaviour
- Sensitive data exposure — prompt, training-data and context leakage
- Insecure tool & plugin use — agents taking unsafe or unauthorised actions
- Excessive agency — over-permissioned automation and workflows
- Model & output handling — unsafe rendering, injection via responses
- Supporting API & app security — the endpoints and app around the model
Framework mapping
- OWASP Top 10 for LLM Applications — the AI-specific risk baseline
- NIST AI Risk Management Framework — governance and risk alignment
- ISO/IEC 42001 — AI management system readiness

Why choose Aesparrow for AI security
Built for modern AI
LLM apps, agents and AI APIs — not generic testing bolted onto AI.
OWASP LLM & NIST AI RMF
Structured coverage of the risks unique to AI systems.
Full-stack assessment
Model, prompts, tools, APIs and guardrails — tested together.
Free remediation re-test
We verify your fixes and re-issue the report.
If you are shipping AI features — chatbots, copilots, agents or LLM APIs — you need testing built for how they actually fail. Talk to us about an AI security assessment scoped to your models and workflows, and about ISO 42001 readiness for AI governance.
Frequently Asked Questions
What kinds of AI systems do you test?+
Chatbots and copilots, retrieval-augmented (RAG) applications, autonomous agents, and LLM/AI APIs — including the tools and integrations they can call.
Is prompt injection really a serious risk?+
Yes. Prompt injection — especially indirect injection through content the model ingests — can cause an AI system to leak data, ignore its guardrails, or take unsafe actions. It is the top risk in the OWASP LLM list and requires purpose-built testing.
Do you also test the normal application and APIs?+
Yes. Most real-world AI risk still comes from the surrounding application and API layer, so we assess those alongside the model-specific tests.
Can you help with ISO 42001 / AI governance?+
Yes — we can pair the technical assessment with ISO 42001 readiness so your AI governance holds up to customers and regulators.

Web Application VAPT
Your web application is the front door to your business — and the first thing an attacker probes. Aesparrow’s Web Application VAPT (Vulnerability Assessment and Penetration Testing) combines deep manual testing with trusted tooling to find the flaws that automated scanners miss: broken access control, business-logic abuse, injection, and authentication weaknesses. You get a clear, prioritised picture of what a real attacker could do, and exactly how to fix it before it costs you.
API Security Testing (API VAPT)
APIs power your apps, partners and integrations — and they’re now the most attacked part of most modern platforms. Because APIs expose business logic directly, a single broken authorisation check can leak every customer’s data. Aesparrow’s API Security Testing (API VAPT) is built around the OWASP API Security Top 10 and goes deep on the flaws automated tools consistently miss: broken object-level authorisation (BOLA/IDOR), mass assignment, and business-logic abuse.
Red Team Assessment
A penetration test answers "is this system vulnerable?" A red team assessment answers a harder, more valuable question: "if a determined attacker targeted our business, would we detect and stop them?" Aesparrow’s red team runs a goal-based, adversary-style simulation across people, process and technology — emulating real threat actors to test your detection and response, not just your patch levels.
