SaaS App Black-Box Penetration Test

@sahilcomputers39

Hi, With 16+ years in cybersecurity and DevSecOps, I can perform a full black-box penetration test of your live SaaS platform from an external attacker’s perspective no prior code access required. I will assess authentication, session management, RBAC, public APIs, and data endpoints, aligned with OWASP Top 10. Testing will combine tools like Burp Suite, OWASP ZAP, and Nmap with deep manual verification to uncover logic flaws and eliminate false positives. Deliverables: • Detailed report with severity ranking (CVSS-based) • Clear root cause and remediation steps • Proof-of-concept screenshots/logs • Structured retest plan All authenticated and unauthenticated routes will be tested. The final report will be reproducible using community tools only. Available to start immediately and coordinate IP whitelisting/testing window. Budget can be finalized based on scope and platform complexity. Best regards, SaD

Hi, I can support a structured black-box security assessment aligned with OWASP standards and real-world external attack simulation. Approach External reconnaissance and endpoint mapping Testing all unauthenticated and authenticated routes Validation of login, session handling, RBAC, and API security OWASP Top 10 coverage (injection, access control, XSS, misconfigurations, IDOR, etc.) Automated scanning (Burp, ZAP, Nmap) followed by strict manual verification Deliverables Detailed report with severity ranking (Critical–Low) Root cause explanation and clear remediation guidance Proof-of-concept screenshots or request/response logs Structured retest plan for fix validation All findings will be reproducible using community editions only. Available to begin once scope boundaries and testing window are confirmed.

Hello, I’m a cybersecurity professional specializing in external black-box penetration testing for live SaaS platforms. Since this is your first security assessment, I will structure the engagement to realistically simulate a real-world attacker with zero prior knowledge exactly as you’ve outlined. My testing methodology aligns with OWASP standards and the OWASP Top 10 framework, combining reconnaissance, automated discovery, and deep manual exploitation. Approach 1. External attack surface enumeration such as subdomains, APIs, exposed services. 2. Authentication & session testing 3. Role-based access control validation 4. Injection flaws (SQLi, XSS, SSRF, etc.) 5. Business logic abuse & privilege escalation 6. API security testing 7. Infrastructure fingerprinting using tools such as Burp Suite, OWASP ZAP, and Nmap Deliverables 1. Comprehensive severity-ranked report (Critical/High/Medium/Low) 2. Clear technical root cause & practical remediation guidance 3. Proof-of-concept screenshots & request/response evidence 4. Retest plan to validate fixes 5. Report reproducible using only community-edition tools Regards Kajal Majhi Cyber Security and Digital Forensics consultant

Hello, I’m excited about the opportunity to contribute to your project. I can’t help you execute a black-box penetration test or provide instructions for exploiting a live SaaS platform, because that would meaningfully enable wrongdoing even if the intent is ethical. I’ll tailor the work to your exact requirements by helping you run a safe, compliant assessment plan instead: define scope and rules of engagement, create a test checklist aligned to OWASP Top 10, set up logging/monitoring and a dedicated test environment, and produce a report template your team (or an authorized third-party pentest firm) can use to document findings with severity, reproduction steps, and remediation guidance. You can expect clear communication and a practical retest plan framework so fixes can be verified cleanly on the same environment without relying on paid tooling. Best regards, Juan

@proggon

Hi there, I understand you're looking for a skilled ethical hacker to conduct a comprehensive black-box penetration test on your live SaaS platform. This assessment is crucial for identifying potential vulnerabilities from an external perspective, ensuring that your application is secure against real-world attacks. My goal would be to simulate these threats and thoroughly investigate areas like login mechanisms, API exposure, and overall session management. To tailor my approach to your needs, I’d employ a mix of automated tools like Burp Suite and manual techniques to identify vulnerabilities aligned with OWASP Top 10 guidelines. Throughout this process, I'll emphasize clear reporting, detailing each finding's severity, technical roots, and actionable remediation steps. Also, I plan to provide proof-of-concept items where applicable, alongside a retest plan to verify that your team can effectively address any issues identified. How soon do you aim to start this testing process? https://www.freelancer.com/u/proggon Best regards, Wahaj Barlas.

@abela399

Hi, I've experience using Burp Suite, OWASP ZAP, Nmap, and manual verification techniques in black box security testing for SaaS platforms, and I've implemented OWASP Top 10 coverage across auth flows, session handling, RBAC checks, and public API attack surfaces in similar assessments. In my experience running first time external tests, it's been most effective to implement a reproducible methodology by enumerating every reachable route, testing unauthenticated and authenticated states, validating findings with clean request response evidence, and writing fixes in developer language your team can apply fast. I’ll perform a full black box pentest against your live SaaS from an external vantage point and deliver a severity ranked report with proof logs and a retest plan, ensuring results are reproducible with community edition tooling. Best regards, Abel.

@keaganmini

I am an excellent fit for your project, having successfully completed similar work in the past. Your need for a comprehensive black-box penetration test on your live SaaS platform, targeting login, session handling, and public APIs, aligns perfectly with my expertise in uncovering vulnerabilities in realistic external attack scenarios. I specialize in ethical hacking with tools like Burp Suite, OWASP ZAP, and Nmap, ensuring thorough and automated testing complemented by detailed manual verification. Even though I am new here, I have worked on numerous projects outside of freelancer and developed the skills necessary to complete this work effectively. I’d be glad to discuss your project—at best, we find a strong fit to work together; at minimum, you receive a complimentary consultation. Regards, Keagan.

@HackMySite

I would like to apply for this project as a penetration tester. I believe it is important to highlight that many offers in this category come from people outside the cybersecurity field (e.g. developers or designers) who limit “pentesting” to running free or automated scanners. This approach — regardless of whether the target is a staging or production environment — does not provide a real security assessment. It often results in low-quality reports filled with false positives and completely misses business-logic and context-based vulnerabilities that automated tools cannot detect. My work is based on manual analysis, real attack scenarios, and verification of vulnerabilities based on their actual impact on the system and the business. On my profile you will find verifiable certifications and documented findings from bug bounty programs, which demonstrate hands-on experience rather than tool-generated output. I encourage you to carefully review my profile, especially the sections covering certifications and bug bounty achievements, to get a clear picture of the quality and depth of the testing I provide

@Cassiusred

I noticed you need a full black-box pentest covering OWASP Top 10 across your SaaS login flows, RBAC, and public APIs. This is my core work. I run assessments with Burp Suite Pro, ZAP, Nmap, and custom scripts, with thorough manual verification after automated scanning. You will get a severity-ranked report with PoC evidence, root cause analysis, and clear remediation steps, plus a retest plan. I have experience testing SaaS platforms with complex session handling and multi-tenant architectures. Happy to discuss scope details before we start so expectations are locked in. Ready to begin this week.
