LLM application security

AI Security Assessment

Threat modelling and red-team reviews for LLM, RAG and agent applications: prompt injection, data exfiltration, tool abuse and the OWASP LLM Top 10.

LLM features open new attack paths: injected instructions in documents, leaked system prompts, over-permissioned tools. We test for them and harden the design.

What you get

  • Threat model of your AI features and data flows
  • Red-team findings with reproducible payloads
  • Guardrails: input/output filtering, tool permissions, isolation
  • Re-test and sign-off after fixes

Deliverables

  • Assessment report mapped to the OWASP LLM Top 10
  • Remediation plan and, optionally, the implementation
  • Regression tests for the findings

Stack we use

  • OWASP LLM Top 10
  • Prompt injection
  • Guardrails
  • Evaluation

From requirements to production

  1. 01Requirements

    A discovery call, then a written scope with acceptance criteria and a realistic estimate.

  2. 02Design

    Architecture, data model and API contracts agreed before code is written.

  3. 03Build

    Short iterations with demos; code reviewed, typed and documented as we go.

  4. 04Test

    Unit, integration and end-to-end tests; QA passes against the acceptance criteria.

  5. 05Deploy

    Docker, CI/CD and cloud setup with monitoring, then a production handover.

  6. 06Support

    Production bug fixing, performance tuning and improvements after launch.

Ways to work together

Fixed-scope project

A written scope, milestones and a fixed price. Best for a defined feature, integration, migration or redesign.

Monthly retainer

Reserved engineering hours every month for ongoing development, maintenance and production support.

Hourly & advisory

Architecture reviews, code reviews, pairing sessions and second opinions, billed by the hour.

Recent work

W3Colleges: a full redesign that kept every URL

This site is our own case study: a new design system, article reader, listing pages, search, login, hub pages and a CI/CD pipeline, delivered as a child theme without touching WordPress core, while 400+ articles, their URLs and SEO metadata stayed intact.

Questions

Is this a penetration test?

It is an application-level security review focused on the AI features and their integrations, not infrastructure penetration testing.
