Identify Application Vulnerabilities Before They Become Security Incidents
Securebytes provides web application and API penetration testing services designed to identify vulnerabilities that could allow attackers to compromise applications, access sensitive data, bypass authentication controls, or disrupt business operations.
Our assessments use in-depth manual testing techniques to evaluate how applications behave under realistic attack scenarios, with testing aligned to recognised industry methodologies including the OWASP Top 10. Assessments focus on both technical vulnerabilities and business logic weaknesses, helping organisations better understand the security risks within customer-facing and internal applications.
Web Application Testing
Web application penetration testing assesses the security of websites, portals, SaaS platforms, and internally developed applications. Assessments focus on identifying vulnerabilities that could impact confidentiality, integrity, availability, or user trust.
Testing is tailored to the functionality and architecture of the application and typically includes authentication testing, session management analysis, access control validation, input handling, and business logic testing.
Typical areas assessed include:
- Authentication and authorisation controls
- Session management weaknesses
- Injection vulnerabilities
- Cross-site scripting (XSS)
- Business logic flaws
- File upload vulnerabilities
- Insecure direct object references
- Input validation weaknesses
- Security header configuration
- Sensitive data exposure
API Security Testing
API penetration testing focuses on identifying vulnerabilities within REST, SOAP, GraphQL, and other API technologies that could expose sensitive data, allow unauthorised access, or impact backend systems.
Assessments evaluate how APIs authenticate users, validate requests, enforce access controls, and securely handle data between systems and applications.
Typical areas assessed include:
- Broken object-level authorisation
- Authentication weaknesses
- Excessive data exposure
- Rate limiting issues
- Injection vulnerabilities
- Insecure API endpoints
- Token and session security
- Business logic flaws
- API misconfigurations
- Input validation weaknesses
What’s Included
Every web application and API assessment is tailored to the target environment and objectives of the engagement. Standard engagements typically include:
Scoping and application walkthroug
Manual penetration testing
Vulnerability verification and exploitation
Authentication and access control testing
API endpoint analysis
Technical and management reporting
Retest support where required
Access to the Securebytes reporting portal
REAL-TIME REPORTING
Securebytes provides clients with access to a modern reporting portal designed to improve visibility, collaboration, and remediation management throughout the assessment lifecycle. Rather than relying solely on static reports, the portal provides an interactive environment where findings, updates, and remediation activity can be managed in real time.
Real-Time Findings Access
View vulnerabilities and security findings as they are identified during the engagement, allowing remediation activities to begin before the final report is delivered.
Asset-Based Finding Management
Findings can be associated with specific assets, applications, or environments, helping organisations clearly understand where vulnerabilities exist and prioritise remediation effectively.
Integrated Collaboration & Communication
Communicate directly with consultants through built-in finding discussions, enabling efficient clarification, remediation support, and ongoing collaboration throughout the assessment.
Remediation & Retest Tracking
Track remediation progress by marking findings as resolved or risk accepted, creating a clear workflow for remediation validation and formal retesting activities.
