Web application security

Secure the Web Applications Your Business Runs On.

In-depth vulnerability assessment and penetration testing for customer portals, internal dashboards, SaaS products and marketing platforms — with a focus on the access control and business logic flaws that scanners miss.

What we test

Testing coverage across the attack surface

Coverage is tailored to your application. The areas below are assessed where applicable to the agreed scope.

Common weaknesses

Issues we frequently look for

Broken Access Control

Horizontal and vertical privilege escalation, forced browsing and unprotected admin functionality.

Authentication Flaws

Weak password and MFA flows, credential stuffing exposure, unsafe password reset and account enumeration.

Injection

SQL, NoSQL, command and template injection reachable through user-controlled input.

Cross-Site Scripting

Stored, reflected and DOM-based XSS leading to session theft or unauthorized actions.

Business Logic Abuse

Workflow bypass, price and quantity manipulation, replayed transactions and race conditions.

Misconfiguration & Exposure

Insecure headers, verbose errors, exposed debug endpoints, backups and sensitive data in responses.

How we test

A manual-first testing approach

  • Authenticated testing across every user role in scope, so authorization is validated rather than assumed.
  • Automated scanning for breadth, then manual exploitation to confirm impact and eliminate false positives.
  • Application-specific threat modeling to prioritise the flows that carry real business risk.
  • Chained-issue analysis: low-severity findings combined into realistic attack paths.
  • Evidence-backed reporting with reproduction steps developers can follow, plus a retest after fixes.

Aligned frameworks

Assessments are mapped to these industry frameworks and testing methodologies. This does not imply certification by, or partnership with, any of these organisations.

Example tools

Illustrative only — tooling is selected per engagement and is not a guarantee of full coverage. Manual testing remains central to every assessment.
