⭐ What Our Clients Say About Working With Us
The reviews below reflect engagements across web application testing, API security, network penetration testing, mobile app assessments, DFIR investigations, and compliance-focused testing for HIPAA, PCI DSS, SOC 2, and ISO 27001 environments.
Security work is often sensitive by nature. Some clients operate under strict NDAs and can’t be named publicly; we respect that without question. For prospective clients who want a direct reference conversation, we can arrange one on request.

Who We Are and Why We Built This Firm
Pentest Testing Corp was built on a straightforward premise: most security assessments available to growing companies are either automated scans dressed up as penetration tests, or prohibitively expensive engagements from large firms that assign junior analysts to the actual work.
Our CEO, Md. Shofiur has spent years operating at the intersection of offensive security and compliance, conducting manual-led tests, responding to real incidents, and building the kind of technical documentation that development teams can actually act on. He’s recognized as a top-rated cybersecurity professional on Freelancer.com and holds eight active certifications covering ethical hacking, digital forensics, API security, web application testing, and information security governance.
The firm was built to serve clients who need real findings, clear remediation guidance, and a team that stays engaged through the fix cycle, not just through the report.
That philosophy is why our free retest policy exists. We don’t consider an engagement closed until the critical vulnerabilities are confirmed remediated.

How We Conduct a Penetration Test: From Scoping to Report
Every engagement follows a defined methodology, not a script. The specific approach adapts to the target environment, agreed scope, and compliance requirements.
1. Scoping Call
Before any work begins, we hold a scoping conversation to define scope boundaries, rules of engagement, compliance context, timeline, and testing type (black-box, gray-box, or white-box). This is where we align on what success looks like for your team.
2. Reconnaissance and Threat Modeling
We map the attack surface before touching any systems: identifying exposed services, third-party dependencies, authentication mechanisms, and data flow patterns relevant to the scope.
3. Manual-Led Testing
The majority of our testing is conducted manually by certified analysts, not by automated scanners. Tools are used to support the process, not replace human judgment. This matters because business logic vulnerabilities, chained exploits, and configuration-level issues routinely escape automated detection.
4. Exploitation and Validation
Identified vulnerabilities are validated and, where scope permits, exploited to confirm real-world impact. We document proof-of-concept evidence for every finding, not just scanner output.
5. Report Delivery
Our reports include an executive summary for leadership, a technical findings section for your development team, CVSS-scored vulnerability entries with reproduction steps, and a remediation roadmap ordered by risk priority. You can review a full sample before committing to an engagement.
6. Free Retest
Once your team has addressed the findings, we retest all critical and high-severity vulnerabilities at no additional cost to confirm they’re properly remediated.
