Web ApplicationPentesting
We combine expert manual testing with automation to uncover real exploitable issues across authentication, logic, and APIs.
“Modern applications are constantly targeted by attackers—weak authentication, misconfigured APIs, exposed secrets, and business logic flaws lead to real breaches every day.”
Phase 01
Reconnaissance & Discovery
We map your external footprint and define the exposed attack surface.
Phase 02
Target & User Profiling
We analyse roles, data flows and abuse cases to predict attacker behaviour.
Phase 03
Infrastructure & Service Mapping
We enumerate APIs, services and trust boundaries to reveal hidden paths.
Phase 04
Vulnerability Discovery & Exploitation
We manually test and exploit validated issues to demonstrate real risk.
Phase 05
Risk Analysis & Validation
We validate exploitability, prioritise findings and remove noise.
Phase 06
Reporting, Debrief & Retest
We deliver clear reporting, remediation guidance and retesting.
Pentesting Aligned with Industry Standards
EntrySec engagements are mapped to OWASP, SANS and NIST so your engineering and compliance teams can interpret results using the same language as modern security frameworks.
Everything You Need for Compliance
EntrySec pentesting reports are structured so they can be reused for ISO 27001, SOC 2, PCI DSS, GDPR, HIPAA and other assurance frameworks, helping you demonstrate real security maturity to auditors, customers and regulators.

EntrySec is built by former Big Four security leaders who have directed high-complexity, large-scale Web Application Penetration Tests for global enterprises. Our methodology uncovers deep vulnerability classes, business-logic flaws, session management issues, and authentication/authorization weaknesses that automated scanners consistently miss. Through advanced manual exploitation, attacker-centric testing, and precise threat-modeling, we deliver an enterprise-grade approach with unmatched clarity, depth, and technical rigor.
Certified, senior-level testers. Experts specializing in advanced WebApp exploitation.
Independent, unbiased findings. Clear results focused on real business impact—not scanner noise.
Real-world attacker techniques. Chaining, enumeration, bypasses, logic abuse, and deep WebApp exploitation.
Clear, actionable deliverables. Engineering-ready remediation aligned with modern web architectures.
Tailored scoping & senior support. Fully aligned with your systems, workflows, and compliance frameworks.

Frequently asked questions
Clear answers to the most common questions about our penetration testing services and engagement process with your engineering and security teams.
A penetration testing service simulates real-world cyberattacks against your applications, APIs, cloud, and infrastructure. The goal is to safely identify vulnerabilities before attackers do and provide clear, prioritized guidance so your team can fix issues and strengthen your overall security posture.
Penetration testing uncovers critical weaknesses, reduces the likelihood of data breaches, and limits potential financial or reputational damage. It validates security controls, supports compliance with standards such as ISO 27001 and SOC 2, and demonstrates due diligence to customers, partners, and auditors.
The cost depends on scope and complexity: number of applications, APIs, and environments, as well as authentication flows, roles, and integrations. We provide transparent, fixed-fee proposals so you know exactly what is included—no hidden add-ons or surprise charges once the test begins.
Yes. We tailor each engagement to your stack and risk profile. Share a high-level overview of your applications, APIs, infrastructure, and compliance drivers, and we’ll prepare a custom testing plan and quote aligned with your objectives and budget.
Absolutely. Our testing methodology and reporting can be mapped to major frameworks like PCI DSS, HIPAA, SOC 2, ISO 27001, and GDPR. We highlight control gaps, provide evidence you can share with auditors, and include remediation guidance that supports your certification or audit efforts.
Timelines depend on scope, but most projects deliver a full report within 7–15 business days after testing finishes. During the engagement you’ll receive early visibility into critical issues, and once the report is delivered we walk you through findings, answer questions, and provide practical remediation advice.
No. We include at least one full round of retesting at no additional cost. Once you’ve deployed fixes, we revalidate the vulnerabilities, update the report with the new status, and confirm that the risks have been properly addressed.
Pricing is based on clear scoping parameters: type of assessment (web, API, mobile, internal, cloud), number and size of assets, level of access, and any special requirements like out-of-hours testing. We keep the model simple and predictable so you can easily budget and compare options.
Yes. We offer an initial consultation at no cost to understand your environment, objectives, and compliance requirements. From there we recommend an appropriate scope, outline timelines, and answer any questions you have about methodology or reporting.
