Website & Application Security Testing
Website and Application Security Testing is essential for identifying vulnerabilities that could be exploited by cyber criminals. With the rise in online threats, testing your digital platforms regularly ensures they’re resilient against attacks like SQL injections, cross-site scripting (XSS), and API vulnerabilities.
CyberLab’s expert testing services safeguard your critical data, protect your users, and help you maintain trust in an increasingly risky online environment.

Why Website & Application Security Testing?
Website and Application Security Testing identifies vulnerabilities in your digital platforms, such as code flaws or weak configurations, that can be exploited by cyber criminals. Regular testing helps prevent data breaches, secure user information, and maintain trust.
With cyber threats evolving constantly, it’s essential to stay ahead of potential risks by ensuring your websites and apps are fortified against attack.
Identify Critical Vulnerabilities
Detect and address weaknesses in your website or application before attackers can exploit them.
Ensure Regulatory Compliance
Meet necessary compliance requirements, such as GDPR, by implementing secure practices and protocols.
Enhance User Trust
Ensure your site and apps are secure, reassuring users their data is safe from breaches.
Improve Overall Security Posture
Strengthen your digital infrastructure by addressing security flaws across websites, applications, and APIs.
Protecting Local Government with Expert Penetration Testing
“Once the testing phase was complete, CyberLab delivered the report quickly. A team from CyberLab, including a Senior Director, presented the results to senior executives at Nottingham City Council, answered questions and provided interpretation and context for the scores.”
– Mark Smith, Server Support Manager, Nottingham City Council

Website & App Security Testing: The CyberLab Approach
Our comprehensive security testing process identifies vulnerabilities across your websites and applications, using both automated tools and manual assessments. From risk identification to actionable remediation steps, our testing helps you strengthen your online platforms against the evolving threat landscape, ensuring a secure experience for both your users and your business.
Define the scope and objectives for the security testing, including applications, websites, and APIs to be tested.
Use automated tools and manual assessments to identify vulnerabilities like injection flaws, cross-site scripting, and authentication weaknesses.
Evaluate each vulnerability based on its potential impact and the likelihood of it being exploited, prioritising the most critical risks.
Provide detailed guidance on fixing identified vulnerabilities, enhancing security measures, and implementing best practices.
After remediation, conduct re-testing to ensure vulnerabilities have been adequately addressed and security measures are effective.
After completing the security testing, you will receive a detailed report outlining all identified vulnerabilities. The report will categorise each issue by severity and provide actionable recommendations for remediation. It serves as a critical tool for improving your security posture and ensuring that your website or application is resilient against potential threats.
