Cyber Security Services

Scope the right offensive security program for web, API, cloud, red team, and AI security validation.

Engagement Models

Choose your starting point

Scope determines investment. Every engagement starts with a 30-minute discovery call to confirm the highest-risk surface.

Targeted Pilot

5–10 business days

Teams running a first security test or validating a single high-risk surface before launch.

  • Single highest-risk surface
  • Evidence-first findings report
  • Retest note
  • Remediation direction for engineering
Start Security Test

Web & API Program

10–20 business days

Product companies with public-facing APIs and web applications.

  • Web application
  • REST / GraphQL API
  • Authentication & authorization
  • Business logic flows
Start Security Test
Featured

AI & Agent Security

7–14 business days

Teams building or deploying LLM-powered products and AI agents.

  • Prompt injection & indirect attacks
  • MCP tool poisoning
  • RAG data leakage
  • R1 reasoning-trace audit
Start Security Test

Enterprise Program

Custom scope

Organizations with a mature security baseline seeking adversarial validation or continuous coverage.

  • Red team operations
  • Multi-surface engagement
  • Regulatory framework mapping
  • Continuous program option

Frequently Asked Questions

How long does a pilot engagement take?+
A targeted pilot typically spans 5–10 business days. Scope and surface complexity determine the timeline. We confirm the exact timeframe in the initial scoping call.
Do you work with early-stage startups?+
Yes. We scope pilot engagements from pre-Series A through enterprise. The engagement format adapts to the risk surface, not company size.
What does the deliverable look like?+
Every engagement produces evidence-first findings: reproduction steps, impact chain, affected asset, remediation direction, and a retest note. No scanner-generated noise — real exploit evidence.
Can you test AI and LLM systems?+
Yes — this is a core specialisation. We cover prompt injection, tool-call abuse, RAG data leakage, MCP tool poisoning, and reasoning-trace exposure.
How do we start?+
Submit the scope form on this page. We respond with a scoping call invite within one business day. The call takes 30 minutes.
