What’s Behind Your Pentest?
Pick the closest reason. We’ll show what we’d test, what you’d get and how long it usually takes.
The product your customer will use: the web app and its API, grey-box, with test accounts for every role.
An executive summary you can forward, the full report for your developers and, after the retest, a letter of attestation for the customer.
2–3 weeks from kickoff to a retested report
Send us your customer’s security questionnaire. We’ll scope the test to what they actually ask for.
The systems in your audit scope: external perimeter, web app and API.
Findings mapped to SOC 2 (CC4.1, CC7.1) or ISO 27001 Annex A (8.8, 8.29), plus a retest report that shows what you fixed.
Book 6–8 weeks before fieldwork, so there’s time to fix and retest
Auditors ask what happened to the findings. The retest report answers that on one page.
Internal and external tests of your cardholder data environment, plus segmentation testing, as PCI DSS 11.4 requires.
Methodology and results documented to 11.4.1, with fixes retested as 11.4.4 requires.
At least every 12 months and after any significant change
Service providers need segmentation tests every six months (11.4.6).
What changed: new endpoints, auth flows, roles and integrations, plus a check that earlier findings stay fixed.
A focused report before launch. Critical issues reach you the same day we confirm them.
1–2 weeks, planned around your release freeze
Send us the list of new endpoints and changed roles, so testing days go where the risk moved.
How your AI features hold up against manipulated input, whether the system prompt or private data can leak, and what the model’s connected tools can be talked into doing.
Findings mapped to the OWASP Top 10 for LLM Applications (2025) and to Article 15 of the EU AI Act on robustness and cybersecurity.
1–2 weeks per assistant or agent
The riskiest part is usually what the model is allowed to call. We start with its tools, APIs and data access.
Your external perimeter and core product, black- or grey-box.
An independent executive summary written for investors, the full report for your CTO, and a retest of anything critical.
2–3 weeks. A narrower scope can fit a data-room deadline
A report with the retest done reads better in a data room than a list of open issues.

Why TestFort for Penetration Testing
Human-first
strategy
QA engineers look for exploitable vulnerabilities by hand, finding what automated scanning alone leaves unnoticed.
Certified data handling
ISO 27001-certified processes protect sensitive client systems and findings throughout the entire engagement.
Framework-compliant findings
Every vulnerability is tied back to SOC 2, PCI DSS, or GDPR, turning results into audit-ready compliance evidence.
AI & LLM
expertise
We provide dedicated, AIGP-certified coverage for testing AI systems most penetration testing consultants still can’t assess.
How Pen Testing Benefits Your Business
- Lower breach risk
- Improved data protection
- Higher stakeholder trust
- Proven incident response
Penetration Testing for Compliance
Many security frameworks require regular penetration testing. Our reporting approach fits each finding to the standards that auditors and regulators expect.
| Framework | Requirement | How penetration testing helps |
OC 2 | Evidence of controls that protect customer data | Independent testing demonstrates security controls work as intended |
ISO 27001 | Ongoing assessment of information security risk | Regular testing supports risk assessment and treatment requirements |
PCI DSS | Annual penetration testing for cardholder environments | Internal and external testing satisfies Requirement 11 directly |
HIPAA | Safeguards for protected health information | Testing validates technical safeguards around sensitive health data |
GDPR | Appropriate measures to secure personal data | Testing evidences the security measures the regulation calls for |
EU AI Act | Risk management for high-risk AI systems | AI and LLM testing supports required robustness and security checks |
Industry-Specific Penetration Testing
Fintech & Banking
Payment flows, banking APIs, and account systems constantly attract security attacks while being heavily regulated. Testing here focuses on transaction logic, authentication, and PCI DSS-compliant environments to prevent fraud and data theft.
Healthcare & Telehealth
Patient records and digital clinic infrastructure make high-value targets, with HIPAA setting the bar high for protecting them. Testing investigates how health data moves through applications, APIs, and connected devices, minimizing the exposure of sensitive records.
eCommerce & Retail
High transaction volume makes eCommerce and retail solutions a valuable target for attackers, especially for fraud and account takeover. Testing looks at checkout flows, payment integrations, and accounts that hackers can potentially exploit during peak traffic.
AI & Machine Learning
The growth of AI exposes attack possibilities that traditional testing has never accounted for. When testing AI models and LLM integrations, we check for prompt injection, training data exposure, and model manipulation that threaten the entire application.
From unknown risk to a definitive fix list — custom pen testing for any industry and product
What’s Inside a Pen Testing Report
A penetration test is only as useful as the report behind it. Here is how every report goes from a high-level summary to technical details the team needs to act.
Each report includes:
– A retest result focusing on the fix once it’s in place
– A severity rating with CVSS score, so issues can be evaluated by real risk
– Clear reproduction steps and supporting evidence for every vulnerability
– The business impact of exploitation, in terms that speak directly to managers
– Actionable, deeply specific remediation guidance for developers

Latest Testing Insights
How we work
What is penetration testing?
What is penetration testing?Penetration testing is a controlled security assessment in which ethical hackers simulate real-world attacks to find exploitable vulnerabilities before criminals do. Unlike a routine scan, pen testing uses manual techniques that show how far an attacker could actually get — a core part of any serious cybersecurity program.
What is the difference between penetration testing and vulnerability scanning?
Vulnerability scanning is automated: a tool checks systems against known weaknesses and returns a list. Penetration testing goes further, with a human tester exploiting those weaknesses to confirm which are genuinely dangerous. Vulnerability testing and scanning give breadth; pen testing adds the depth that reveals real business impact.
How much do penetration testing services cost?
Cost depends on scope — the number of applications, APIs, or network ranges, the depth of testing, and whether retesting is included. Most pen testing services are priced per engagement after a scoping conversation rather than at a fixed rate. TestFort provides a clear quote once scope is defined, with no open-ended hourly billing.
How long does a penetration test take?
A focused test of a single web application or API typically runs one to two weeks, including the report. Larger engagements across multiple systems, cloud environments, or a red team scenario take longer. Scoping ensures a clear timeline, which is confirmed in writing before work begins.
How often should penetration testing be performed?
The common standard is at least once a year, and again after any significant change that could introduce risk. Frameworks such as PCI DSS and SOC 2 expect regular testing on that cadence, and fast-moving products benefit from more frequent security testing.
