Penetration testing for modern SaaS, AI systems & cloud infrastructure
Your attack surface has changed. AI copilots, LLM APIs, RAG pipelines, and the integrations connecting them are as exploitable as your web app and APIs ever were. We test all of it: web, API, cloud, network, mobile, and AI systems built on the OWASP LLM Top 10. Every engagement is manual-first, with validated proof-of-exploit for every finding and a free retest when you’ve fixed them.

Find and fix exploitable risks before auditors or attackers do
Your auditor needs evidence of a penetration test. Your enterprise customers want proof you take security seriously. Your development team needs actionable findings, not a 200-page PDF they’ll never read.
Most vendors hand you a scanner report dressed up in a PDF. We don’t. Every finding is manually exploited before it enters the report, real vulnerabilities, reproducible, tied to business risk. If you’re deploying AI features, your attack surface includes prompt injection, system prompt leakage, agent abuse, and RAG retrieval poisoning. We test for those too.

External attack surface mapping plus internal lateral-movement simulation from a compromised endpoint.
Bundled assessments, web + API, cloud + network, or full-stack, include a single scoping call, a unified report, and a coordinated timeline. Get a bundled quote →
How we test: a methodology you can show auditors
PHASE 01
Scoping & rules of engagement
We define the attack surface, agree on testing windows and authentication scenarios, and issue written scope confirmation before any testing begins.
PHASE 02
Reconnaissance & threat modeling
We map your architecture, enumerate entry points and your tech stack, and build a threat model tailored to your environment, not a generic checklist.
PHASE 03
Exploitation & validation (manual-first)
Every potential finding is manually exploited or attempted before entering the report. Automated tools support discovery; human judgment decides what’s real.
PHASE 04
Reporting & remediation guidance
Each finding includes a CVSS severity rating, reproduction steps, a business impact statement, a fix recommendation, and compliance mapping on request.
PHASE 05
Retest & closure
An optional retest confirms remediations are correctly implemented, providing documented closure evidence for auditors and enterprise customers.

Penetration testing built for compliance-driven teams
SOC 2 Type II
Findings map to Trust Services Criteria CC6.1, CC6.6, CC7.1, and CC8.1, with evidence packages structured for direct auditor submission.
PCI DSS v4.0
Requirement 11.3 mandates internal and external penetration testing of the cardholder data environment, documented in PCI-compatible format.
HIPAA Security Rule
We assess technical safeguards and deliver findings that support your Security Risk Analysis (SRA) documentation.
ISO/IEC 27001:2022
Testing supports Annex A controls A.8.8 and A.8.29, formatted as risk treatment evidence.
GDPR
We identify vulnerabilities constituting technical failures under Article 32 and provide findings suitable for DPIA documentation.
OWASP LLM Top 10 / AI security
Findings map to the OWASP LLM Top 10 (2025) and align with NIST AI RMF governance requirements for teams deploying AI systems.
Transparent, fixed-price engagement tiers
Fixed prices agreed before testing begins, no time-and-materials estimates, no scope creep surprises.
| Service | Starting from | Typical timeline |
|---|---|---|
| Web application pentest | $5,000 | 5–8 business days |
| API penetration testing | $5,000 | 4–7 business days |
| AI penetration testing | $9,500 | 7–14 business days |
| Mobile app pentest (single platform) | $8,000 | 7–10 business days |
| Cloud penetration testing | $6,500 | 5–8 business days |
| External network pentest | $4,500 | 3–5 business days |
| Internal network pentest | From $6,000 | 5–8 business days |
Complex environments, microservices, or bundled engagements are quoted after a scoping call. AI penetration testing scope depends on system type, integration depth, and whether agentic pipelines or RAG is in scope.
Continuous penetration testing (PTaaS), test as you ship
Annual tests leave 11 months of untested exposure. Our PTaaS model aligns testing to your sprint and release cycle: on-demand testing as you ship new features, sprint-aligned findings with prioritized remediation, and cumulative compliance evidence building throughout the year. For teams shipping AI features continuously, PTaaS means every new LLM integration or agent capability gets assessed before it reaches production, not after.

Why compliance teams trust our process
OSCP CEH API Security for PCI ISO/IEC 27001 Associate CompTIA Security+ / CySA+
AI penetration testing engagements follow the OWASP LLM Top 10 (2025) framework with hands-on adversarial methodology, not automated scanning. Every engagement begins with a signed NDA, yours or ours, with rules of engagement documented before go-live. Test evidence is encrypted in transit and at rest, and all test data is destroyed or returned upon engagement completion.

Frequently asked questions
What is the difference between a penetration test and a vulnerability scan?
A vulnerability scan uses automated tools to identify potential weaknesses based on known signatures. A penetration test goes further: a human tester attempts to actually exploit those weaknesses to determine whether they are real, how severe they are, and what business impact they could have. SOC 2, PCI DSS, and HIPAA specifically require penetration testing, not just scanning.
How much does a penetration test cost?
Engagements start from $4,500 for an external network test and from $5,000 for a web application or API test. Pricing is fixed per scope, agreed before testing begins. Complex environments are quoted individually after a scoping call.
How long does a penetration test take?
Most engagements are completed within 5–10 business days from the agreed testing window start. We provide a timeline confirmation during scoping, and rush engagements can be accommodated depending on availability.
Do I need a penetration test for SOC 2 Type II compliance?
SOC 2 Type II does not mandate penetration testing by name, but most auditors expect it as evidence for Common Criteria controls CC6.1 and CC7.1. Most enterprise customers also require it during vendor security reviews.
Is penetration testing required for PCI DSS compliance?
Yes. PCI DSS Requirement 11.3 explicitly requires penetration testing of systems in or connected to the cardholder data environment, both internally and externally, at least annually and after significant changes.
Can you test in a production environment?
Yes, routinely, with agreed testing windows, safe testing controls, and communication protocols to minimize operational impact. All rules of engagement are documented before testing begins.
Do you test AI systems and LLM applications?
Yes, via a dedicated AI Penetration Testing service built on the OWASP LLM Top 10 (2025): chatbots, LLM APIs, RAG applications, autonomous agents, and copilots, tested for prompt injection, system prompt leakage, indirect injection through retrieved content, excessive agency, and cross-tenant data exposure. Most clients pair this with an API or cloud pentest. Engagements start from $9,500.
Who’s responsible for security if we use a third-party AI model?
The model provider secures the model itself. Everything you’ve built around it, your prompts, retrieval sources, agent permissions, and API connections, is your responsibility. Most real-world AI vulnerabilities live in that integration layer, not the base model. That’s where our testing focuses.
What do you need from our team to get started?
A defined target list (URLs, API endpoints, IP ranges, or app bundle identifiers), a preferred testing window, and either pre-configured test accounts or an agreed approach to authentication testing. We handle everything else.
