Penetration Tester | Web Application & API Security | CEH
Looking for a penetration tester to check whether your web application or API could expose customer data, allow account takeovers, or give users access they shouldn’t have? I can help you test those risks and understand what needs fixing. I’m a Top Rated freelancer and Certified Ethical Hacker (CEH), focused on web application penetration testing, API security testing, and web security. As your pen tester, I combine manual testing with targeted automated checks to find and validate weaknesses that scanners can miss. Launching a new application? Adding customer accounts or payment features? Need an independent security assessment of an existing platform? Tell me what you’re building and what concerns you most, and we’ll agree on a practical testing scope. Here’s what I can help you check: • Web application penetration testing: identify exploitable weaknesses in your website and application workflows. • API penetration testing: test API authorization, data exposure, input handling, and sensitive actions. • Authentication and account security: review login, password reset, OTP, and account recovery flows. • Authorization and access control: check whether users can access another user’s data or perform restricted actions. • Business logic and multi-tenant isolation: test whether workflows can be abused or customer boundaries bypassed. • Session security: assess session handling, logout, and token invalidation. • OWASP Top 10 vulnerability assessment: check for common application security risks. • Vulnerability validation and security retesting: confirm reported issues and verify whether fixes address them. If you need a web pen tester who explains findings clearly, I’ll walk you through what I found, how it could affect your business, and what your developer can do next. You’ll receive: • A clear penetration testing report with severity ratings • Evidence and step-by-step reproduction instructions • Business impact explained in plain English • Practical remediation recommendations • One follow-up discussion to review the findings Send me a brief description of your website, web application, or API, along with your deadline and any specific concerns. I’ll help you define the scope and provide fair, transparent pricing before testing begins.
