Application Security Testing Methods, Layer by Layer

No single tool finds everything. Each method looks at the application from a different angle, and together they cover the code, the running app, and its dependencies.

Four application security testing methods

Static testing (SAST)

Source code scanned for insecure patterns on every change.

Dynamic testing (DAST)

The running application probed the way an attacker would.

Dependency scanning

Open-source libraries checked for known vulnerabilities.

Manual testing

Business logic and access rules reviewed by a specialist.

Security Testing Scoped to Your Real Risks

Testing is scoped to what an attacker would target: an application, its APIs, or a new feature before launch. Deeper testing, including penetration testing, is part of Cognativ's technology audits rather than a standalone service.

What sets the scope of security testing

  1. What is exposed

    Public applications, APIs, and integrations in scope.

  2. What is at stake

    The data and actions an attacker would want.

  3. What changed

    New features, releases, or infrastructure since the last test.

Agree the testing scope

  • Application review
  • API review
  • Pre-release review

Findings Your Developers Can Fix

Each finding comes with severity, evidence, and the fix, and is retested once resolved. Cognativ's Virtual CISO work helped a fintech client keep 100% of key financial customers while improving audit readiness.

From scan results to fixed vulnerabilities

Security Testing Built Into Every Release

Automated checks run in the pipeline on every change, while manual reviews are scheduled around major releases. Security becomes part of delivery instead of a gate at the end.

Application Security Testing Questions

What to expect before you start.

What is application security testing?

Testing an application's code, running behavior, and dependencies for vulnerabilities, using automated tools and manual review.

What is the difference between SAST and DAST?

SAST examines source code without running it; DAST tests the running application from the outside, as an attacker would.

Do you offer penetration testing?

Penetration testing is included in Cognativ's technology audits when the scope calls for it; Cognativ does not offer cybersecurity as a standalone service.

Do you test mobile apps and APIs?

Yes. Web, mobile, and API applications are covered, including authentication and access rules.

Will testing slow down our releases?

Automated checks run in the pipeline in minutes; deeper tests are scheduled around major releases.

How does a project start?

With a free first consultation about the applications you want tested, then a short discovery that sets scope, team, and price before work begins.
