Application Security Testing Services we provide

Penetration Testing

Subject your app to an ethical attack by cybersecurity experts before it’s done unethically by someone else. Use various tools and methods to diagnose vulnerabilities and bulletproof your product.

Dynamic Application Security Testing

Apply the best DAST practices to locate faults in runtime, securing cookie & session management, authentication, memory, and more. This black-box approach is optimal for guarding against data injections.

Static Application Security Testing

Secure the very code of your application against possible imperfections using SAST expertise. This white-box approach is to nip any problem in the bud and can be used at the early stages of development.

Network Penetration Testing

Identify the venues for potential attacks in your external systems' network and its security controls to safeguard against malware, DDoS, DNS, APTs, and other threats for robust and secure functioning.

IoT and Embedded Software Testing

Minimize the inherent risk of IoT – while such devices account for >1/3 of network infections, play safe by engaging experts to improve the security posture of your product and bring value to the users.

Thick Client Testing

Use 2-tier or 3-tier thick client architecture when feasible and with fewer security concerns by analyzing the client's interaction with the server & entry points and securing the overall system.

We also provide:
  • • Mobile Application Security Testing (MAST)
  • • Red-Team Attack Simulation
  • • Security Code Reviews
  • • Compliance testing (HIPAA and more)
  • • Database Security Testing
  • • Interactive Application Security Testing (IAST)
  • • Test Coverage Analysis
  • • Software Composition Analysis (SCA)
  • • Runtime Application Self-Protection (RASP)
  • • Infrastructure Security Audit

How is application security testing performed?

Application security is tested using a variety of activities, including white-box (with access to code) and black-box approaches. These include SAST and DAST (static and dynamic application security testing, respectively), software composition analysis, etc. Notably, these activities are performed at different development and maintenance stages, including manual and automated methods.

Why is application security testing important?

With the rising role of the cloud, as well as the interactive emphasis in Web 2.0 and the advent of IoT devices, the space for potential attacks has increased. Application security testing allows taking timely measures against possible breaches, data leakage, DoS (denial of service), and other threats without waiting for issues to happen.

What is vulnerability testing?

Application vulnerability testing is a process of assessing application security aimed at diagnosing and documenting possible weak spots – ranging from code bugs to misconfigurations or missing security features. These activities rely on manual and automated methods and are part of a broader security strategy.

Do all mobile applications need penetration testing?

In general, yes, because there are two main reasons to secure the application with pen testing: the business/functional considerations (avoiding denial of service) and data security compliance. With the latter, the more sensitive or confidential data your app deals with, the more rigorous penetration testing should be. We at Relevant, however, advise against half-measures and advocate for full-scale security testing, including pen tests.

When should security testing be done?

In an ideal risk-based approach, security testing is performed throughout the SDLC (software development life cycle). At the development stage, SAST (static security testing) is run, with SCA (software component analysis) done concurrently and later at the integration stage. Starting with the UAT stage, dynamic testing and mobile-specific methods are introduced, and RASP (runtime application self-protection) is in production.
