Web Application & API Security
Web application security testing
Secure the digital services your customers depend on.
Web Application & API Security
Web applications and APIs often provide direct access to sensitive business processes and information.
They are also continuously accessible to attackers.
Digital Synergy provides application security testing designed to identify weaknesses before they become data breaches or service disruptions.
Web Application Security Testing
Modern web applications are complex systems involving:
- Authentication
- User roles
- APIs
- Databases
- Cloud services
- Third-party components
- Business workflows
Security testing should therefore go beyond basic automated scanning. Our approach evaluates both technical vulnerabilities and application behaviour.
API Security Testing
APIs connect applications, services, mobile devices and business systems. A poorly protected API can expose sensitive data even when the visible application appears secure.
Testing can assess:
- Authentication
- Authorisation
- Object-level access control
- Data exposure
- Rate limiting
- Input validation
- API endpoints
- Business logic
- Token handling
- Security configuration
Automated and Expert-Led Testing
Automated assessment provides broad and repeatable coverage.
Expert-led penetration testing provides deeper analysis of vulnerabilities requiring context or business understanding.
Used together, these approaches provide stronger application security assurance.
Continuous Application Security
For security-sensitive applications, continuous or recurring application security testing can provide greater assurance than a single annual assessment.
