Application Security

A complete suite of security testing for the application-layer to find vulnerabilities before they become business risks.

Application security testing capabilities

From customer-facing platforms to critical internal systems, application security risks can disrupt operations. Our testing methodologies address all layers of application risk to provide complete security coverage.

Dynamic Application Security Testing (DAST)

Identify exposed vulnerabilities in live applications by validating real-world attack paths and analysing run-time data flows across web and application layers.

Static Application Security Testing (SAST)

Uncover security flaws early by analysing source code for insecure logic, data exposure risks, and structural weaknesses before they reach production.

API Security Testing

Secure your APIs by evaluating the authentication and authorization gaps, logic flaws and data validation weaknesses that lead to system compromise.

End-to-end coverage across the application lifecycle

From mobile binaries to CI/CD pipelines, we cover every stage of design, build, and deployment so vulnerabilities never reach production.

Mobile Application Security

Binary, runtime, and platform-specific testing for iOS and Android apps including secure storage, biometric flows, and reverse-engineering resistance.

Penetration Testing

Manual, exploit-validated black-, grey-, and white-box engagements against web apps, APIs, and supporting infrastructure.

Software Composition Analysis

Track open-source and third-party dependency risk across SBOMs, CVE feeds, and licence obligations with prioritised remediation guidance.

Threat Modeling

Architectural risk workshops, STRIDE and PASTA analysis, and design-stage threat decomposition to harden controls before code is written.

DevSecOps Integration

Embed SAST, DAST, secrets scanning, and SCA into CI/CD pipelines with policy-as-code gates and developer-friendly IDE feedback loops.

Secure Code Review

Expert-led manual review of high-risk modules, authentication flows, cryptographic primitives, and integration boundaries.

Red Team Exercises

Adversary-simulation engagements that test detection and response across the application stack, identity layer, and supporting cloud services.

Secure SDLC Advisory

Process maturity assessment and a roadmap to embed security gates, training, and metrics across requirements, build, release, and operate phases.

Frequently asked questions

What is application security testing and why is it important?

Application security testing is the process of evaluating software applications to identify vulnerabilities — such as injection flaws, broken authentication, and misconfigurations — before attackers exploit them. It's important because over 75% of successful breaches now target the application layer. Regular testing protects sensitive data, ensures regulatory compliance, and prevents costly post-deployment fixes.

What is the difference between SAST and DAST?

SAST (Static Application Security Testing) analyzes source code during development to catch vulnerabilities early, before deployment. DAST (Dynamic Application Security Testing) tests running applications from the outside, simulating real attacks. SAST finds issues in code logic; DAST finds issues in runtime behavior. Using both gives full coverage across the development lifecycle.

What is the difference between vulnerability scanning and penetration testing?

Vulnerability scanning is automated and identifies known weaknesses across systems quickly and at scale. Penetration testing is manual, performed by ethical hackers who simulate real-world attacks to test how defenses hold up under skilled adversaries. Scanning tells you what's potentially exploitable; pen testing proves what actually is. Most compliance frameworks (PCI DSS, ISO 27001) require both.

What is API security testing and why does it matter?

API security testing evaluates the APIs that connect modern applications to identify vulnerabilities like broken authentication, excessive data exposure, and rate-limiting flaws. It matters because APIs now handle the majority of web traffic, and the OWASP API Security Top 10 reflects how attacker focus has shifted. Without API testing, breaches in connected systems can expose data far beyond the API itself.
