Different systems.
Same security discipline.

Every system has a different attack surface. Our engagements are shaped around the technology, functionality, and security questions that matter for each environment.

01

WEB APPLICATION

Application Security Assessment

A structured assessment of a customer-facing web application, focusing on authentication, authorization, application logic, and exposed functionality.

/ 06 — Engagement approach

Every engagement starts with understanding the system.

Security testing is most useful when the testing process, evidence, and final findings remain connected to the actual technology being assessed.

01

Understand

Define the systems, objectives, technology, and assessment scope.

02

Investigate

Explore the attack surface and investigate potential weaknesses.

03

Validate

Confirm findings and understand their technical significance.

04

Document

Provide evidence, technical context, and remediation guidance.

05

Retest

Verify that addressed findings have been properly resolved.
