Summary
Key results
Reduced risk of launching an application with unresolved vulnerabilities
Clear remediation path before production deployment
Building strong security posture before launch
For companies operating in the security services sector, trust, data protection, and operational reliability are core business requirements. Before launching a new web application, the client needed to make sure that potential vulnerabilities were identified and addressed before they could affect the production environment.
The application required more than a basic technical check. The company was looking for a partner that could provide a comprehensive security assessment before go-live to verify application resilience, support the remediation of detected vulnerabilities, and protect application integrity.
Without this verification, the company risked releasing a system with unresolved weaknesses that could affect sensitive data protection and compliance with applicable industry standards. To reduce this risk, the client chose Sii Poland to assess the application before production release.
Structured security verification before go-live
Sii Poland cybersecurity experts assessed the new web application to verify its resistance to real-world attack scenarios and support safe deployment.
The scope of work included:
- Comprehensive security verification of the new web application
- Vulnerability assessment to identify potential weaknesses
- Grey-box penetration tests with manual exploitation of detected vulnerabilities
- Testing in line with the Penetration Testing Execution Standard (PTES)
- Performing source code assessment
- Compiling detailed penetration test reports with identified vulnerabilities and remediation recommendations
Stronger application security
With Sii Poland’s support, the client reduced the risk of releasing a new web application with unresolved security issues. The penetration tests simulated realistic attack paths and helped verify how the application’s defenses performed under controlled offensive testing conditions.
The project also gave the client a practical basis for remediation before deployment. Instead of receiving only a list of technical findings, the company gained detailed reports showing detected vulnerabilities and recommended corrective measures. This targeted approach made it easier to plan fixes, address the most relevant risks first, and support compliance with applicable industry standards before production release.
By combining penetration testing with source code assessment, Sii helped the client validate both application behavior and the underlying implementation. This strengthened the application’s security posture, increased confidence in its readiness for launch, and supported better protection of sensitive data from the start.
