Core Service
Application Security
Security embedded from the first line of code.
We review your applications, APIs, and authentication flows for vulnerabilities that automated tools miss. Then we help you fix them — permanently. Every engagement is led by senior practitioners who've seen how applications break in the real world.
Our Approach
How We Assess Your Application Security
-
Scoping & Threat Modeling
We work with your team to understand the application architecture, data flows, trust boundaries, and business logic. This becomes the foundation of our entire engagement.
-
Static Analysis (SAST)
Manual and tool-assisted static analysis of your codebase — identifying insecure patterns, dangerous functions, hardcoded secrets, and logic flaws before runtime.
-
Dynamic Testing (DAST)
Active testing of your running application — probing inputs, authentication flows, session management, authorization controls, and business logic under realistic conditions.
-
API & Integration Security
Deep review of REST, GraphQL, and gRPC APIs — mass assignment, BOLA/BFLA, improper rate limiting, JWT weaknesses, and third-party integration risks.
-
Dependency & Supply Chain Audit
Identifying vulnerable third-party libraries, outdated dependencies, and supply chain risks that could expose your application to known CVEs.
-
Reporting & Fix Guidance
A clear, prioritized report with executive summary, technical findings, proof-of-concept evidence, and step-by-step remediation guidance. Followed by a debrief call and free re-test.
