Application security testing is the process of assessing software applications to identify security weaknesses that could be exploited to compromise the application, expose sensitive data, or impact users.
Testing typically covers a range of application types, including web applications, web services and APIs, mobile applications, and thick client software, and is carried out in line with recognised standards such as guidance from OWASP.
Application security testing provides organisations with confidence in the security of applications that support critical business processes and handle sensitive data. By identifying and addressing weaknesses, organisations can reduce the likelihood of successful attacks, limit business disruption, and protect users.
Beyond vulnerability identification, testing supports improved security decision making by highlighting where investment and remediation effort will have the greatest impact. Alignment with recognised standards such as guidance from OWASP enables teams to improve security in a measurable and sustainable way.
Application security testing initiates by understanding the application functionality and data flows, and threat modelling. This helps identify realistic attack scenarios and ensures testing is focused on the areas of greatest risk.
Testing is primarily manual, supported by automated tools where appropriate to improve coverage and efficiency. The outcome is clear, risk-focused reporting that explains findings, impact, and practical remediation steps, enabling teams to address issues effectively and improve overall application security.
OWASP (the Open Web Application Security Project) is a non-profit organisation that produces widely adopted guidance and resources for improving application security, including the OWASP Top Ten and OWASP API Security Top Ten.
OWASP provides widely recognised, vendor-neutral guidance based on real-world application risks. Aligning testing to OWASP helps ensure assessments focus on the most common and impactful security issues, using an approach that is understood by developers, security teams, and auditors.
Our service provides independent assessment and testing only. We do not design, build, or implement application changes or security controls; however, our reports include clear, risk-based recommendations to support mitigation and remediation planning.
Web applications, APIs and web services (REST and SOAP), mobile applications, and thick client or desktop applications can all be assessed.
Yes, subject to appropriate authorisation and scope. Testing can help organisations understand risk in externally developed or hosted applications.
Testing is planned and scoped to minimise disruption, with higher-risk activities discussed and agreed in advance. We will work with you to choose an appropriate environment (such as staging or production) for testing.
Reports are designed to be understood by both technical and non-technical audiences. Our summaries and findings are presented at the appropriate level of detail to clearly explain risk, impact, and recommendations for each finding.
Yes. Application security testing is commonly used to support internal assurance, governance activities, and regulatory or contractual requirements.
