Their semiconductors are used for numerous applications across industries providing connectivity. ![Leading semiconductor company logo](https://media2.oshyn.com/-/media/Oshyn/Case-Studies/Ongoing-Web-Application-Security-Program/cs_intro_web-application-security-program.jpg?rev=9d11631e6a2244d594ebffd2f0ac3c7c?h=564&w=476) - Services - DevOps for Sitecore - Technologies - Web Applications Penetration Testing Scanner - Custom reporting framework - Secure Communication & Documentation tools - Azure DevOps #### Oshyn reduces critical vulnerabilities by 70% for a leading semiconductor company. ## The Challenge A leading semiconductor company manufactures components that power connectivity across a wide range of consumer and commercial applications. Procurement teams and engineers rely on them to access precise technical specifications, evaluate components, and make sourcing decisions, so they need to maintain secure infrastructure. As a company in a highly regulated industry, the semiconductor company faced pressure from compliance frameworks, including SOC 2, PCI-DSS, and HIPAA, to demonstrate documented, repeatable security testing across its web applications. However, their existing approach was more reactive than proactive, meaning vulnerabilities were only found after an incident or during third-party audits. Threats, including SQL injection and cross-site scripting, were not being addressed in any structured way. The client needed a security program that could help them identify vulnerabilities before they could be exploited and deliver clear remediation roadmaps rather than raw findings. They also needed help reducing the attack surface of their web applications and providing documented, audit-ready evidence to satisfy compliance requirements. They were looking for a collaborative partner to help them implement the program rather than simply dropping off a report, so they turned to Oshyn for assistance. ## The Solution Oshyn was selected for its deep expertise in web application security and proven track record of being a true implementation partner. The team designed and implemented a structured, recurring Vulnerability Assessment and Penetration Testing program, embedding it into the client's annual technology roadmap. The program runs on a bi-annual schedule, with on-demand scanning occurring after key events such as major releases, infrastructure changes, or compliance deadlines. As part of the program, Oshyn's IT and DevOps security team executes full black-box and gray-box penetration testing across all in-scope web applications using a DAST engine that covers 80-plus vulnerability categories aligned with the OWASP (Open Worldwide Application Security Project) Top 10, which highlights the most critical web security application risks, and more. This gives the semiconductor company broad, consistent coverage without relying on internal security resources. Oshyn reviewed every finding from the testing program in the context of the client's specific technology stack. They separated exploitable vulnerabilities from theoretical risks to reduce noise and produced remediation guidance for the development team to address. After each scan, Oshyn and the client conducted a joint action-planning session in which both teams defined the priorities and agreed on a remediation roadmap. Oshyn also tracked those findings across cycles to give the client a clear view of how its security posture improved over time. ![Laptop Screen with a business woman](https://media2.oshyn.com/-/media/Oshyn/Case-Studies/Ongoing-Web-Application-Security-Program/solutions_laptop_web-application-security-program.png?rev=32b5496f10a346c284e449db164482fb?h=684&w=1219) ![Microchip circuit board](https://media2.oshyn.com/-/media/Oshyn/Case-Studies/Ongoing-Web-Application-Security-Program/cs_thumb_web-application-security-program.jpg?rev=864c381a915747aaa5dbb70025a7a2a0) ![Man in protective suit and glasses holding semiconductor chip for a computer](https://media2.oshyn.com/-/media/Oshyn/Case-Studies/Ongoing-Web-Application-Security-Program/cs_hp_thumb_web-application-security-program.jpg?rev=1701fe596d70493ea9879e0259fbafe1) Ongoing Web Application Security Program Reduces Critical Vulnerabilities by 70% for Leading Semiconductor Company Ongoing Web Application Security Program Reduces Critical Vulnerabilities by 70% for Leading Semiconductor Company ![Leading Semiconductor Company logo](https://media2.oshyn.com/-/media/Oshyn/TabbedCustomerCarousel/client_semiconductor-company_logo-white.svg?rev=25c9808de5484cf9b95424a13ad58b9a) ![Microchip circuit board](https://media2.oshyn.com/-/media/Oshyn/Case-Studies/Ongoing-Web-Application-Security-Program/cs_list_thumb_web-application-security-program.jpg?rev=422abd644ff240cc9f07dd44cb202ecd) ![Leading Semiconductor Company logo](https://media2.oshyn.com/-/media/Oshyn/TabbedCustomerCarousel/client_semiconductor-company_logo-white.svg?rev=25c9808de5484cf9b95424a13ad58b9a) ![Leading Semiconductor Company logo](https://media2.oshyn.com/-/media/Oshyn/TabbedCustomerCarousel/client_semiconductor-company_logo-white.svg?rev=25c9808de5484cf9b95424a13ad58b9a) Ongoing Web Application Security Program Reduces Critical Vulnerabilities by 70% for Leading Semiconductor Company ## The Outcome Oshyn helped the semiconductor company reduce its open high-severity vulnerability findings by 70% after two scan cycles. They also reduced the mean remediation time by approximately 40%. The company’s security posture continues to improve with each cycle as the remediation process matures, and they now have compliance-ready documentation of its security testing activities, supporting regulatory certifications and executive reporting.
