Security Testing

End-to-end application security (AppSec) — penetration testing, static and dynamic analysis, dependency and supply-chain checks, and secure-SDLC guidance across your web, API, and mobile applications.

Overview

Secure the whole application lifecycle.

Application security is more than a once-a-year pentest. AppSec is a continuous discipline — finding and fixing vulnerabilities across design, code, dependencies, and runtime, and building security into how your teams ship software.

We combine manual penetration testing with SAST, DAST, and software-composition analysis, then help you embed secure-by-default practices into your SDLC and CI/CD. The result is fewer vulnerabilities reaching production and faster, cheaper fixes.

FAQ

Application security testing FAQ

The questions we're asked most about scope, cost, and timing.

How much does application security testing cost?
AppSec engagements typically start around €2,000 for a focused test and scale into an ongoing programme. Pricing depends on the number of applications and your maturity. Use our estimator for a tailored figure.
What is the difference between AppSec and penetration testing?
Penetration testing is a point-in-time assessment. AppSec is the broader, continuous discipline — combining pentesting with SAST/DAST, dependency analysis, threat modelling, and secure-SDLC practices.
Do you cover web, API, and mobile?
Yes — application security testing spans all three, plus the pipelines and dependencies around them.
Can you help us build a secure SDLC?
Yes — we help integrate security tooling and secure-by-default patterns into your development workflow and train your engineers.
Do you offer ongoing AppSec, not just one-off tests?
Yes — we run continuous AppSec programmes with recurring testing, pipeline integration, and developer enablement.
Is AppSec a one-off or ongoing?
Both — we deliver point-in-time tests and ongoing AppSec programmes that integrate security into every release.
What is the difference between SAST and DAST?
SAST analyses source code statically; DAST tests the running application dynamically. We combine both with manual testing for full coverage.
Can you help us reduce vulnerabilities over time?
Yes — beyond finding issues, we help fix the root causes through secure-SDLC practices and developer enablement.
Do you train our developers?
Yes — AppSec and secure-coding training is available and pairs naturally with testing.
How does AppSec support compliance?
It evidences secure development and regular testing expected by ISO 27001, SOC 2, and PCI DSS.

A 30-minute scoping call costs nothing. A production vulnerability costs considerably more.
