Web Applications Pentesting

Identify critical vulnerabilities in your web applications and APIs before attackers exploit them.

We combine deep manual testing, OWASP-based methodologies, and AI-assisted analysis to uncover real-world security risks across your application stack.

When is web app pentesting essential?

Before release or major updates
Ensure your application is secure before going live or after significant changes.
For compliance and client requirements
Required for PCI DSS, SOC 2, ISO 27001, and increasingly expected under DORA, EU CRA, and other regulatory frameworks.
After security incidents or concerns
Validate whether vulnerabilities exist and assess overall application security posture.

What we assess in web applications and APIs

Our testing is based on OWASP Top 10 and OWASP Testing Guide covering both frontend and backend layers:

  • Broken access control (IDOR, privilege escalation)
  • Authentication and session management flaws (weak tokens, session fixation)
  • Injection vulnerabilities (SQL, NoSQL, command injection)
  • Cross-Site Scripting (XSS) and client-side attacks
  • API-specific risks (rate limiting issues, excessive data exposure, mass assignment)
  • Business logic vulnerabilities (bypassing workflows, abuse of functionality)
  • Security misconfigurations (headers, CORS, debug endpoints)
  • Sensitive data exposure (improper encryption, data leaks)

We simulate realistic attacker behaviour, including chaining vulnerabilities and targeting backend logic.

FAQ

How long does a web app pentest take?

Typically 5-10 business days depending on the number of features, user roles, and API endpoints in scope. We agree the timeline during the scoping call.

Do you test authenticated areas?

Yes - we test all user roles: unauthenticated, standard user, privileged user, and admin. Privilege escalation between roles is a primary testing objective.

Will testing affect our production environment?

We coordinate testing windows with your team. For aggressive tests (SQL injection payload chains, DoS-risk payloads), we recommend a staging environment. Non-intrusive tests can run safely in production.

What's the difference from running a vulnerability scanner ourselves?

Automated scanners identify known CVEs and surface-level issues - roughly 25-30% of real vulnerabilities. Manual testing uncovers logic flaws, chained attack paths, and context-specific misconfigurations that scanners cannot reason about.

Do we get a retest after fixing the issues?

Yes - one retest cycle is included within 30 days to verify that reported vulnerabilities have been correctly remediated.

What our customers say

We were very impressed with the skills and knowledge of Dhound security experts, as well as how effectively they built communication with everyone, and how they made the whole penetration testing process very simple and clear for us.

uxpressiaYuri Vedenin, Founder at UXPressia

We enjoyed working with Denis. He's a true professional. The collaboration gave us a lot including a system audit and PHP vulnerability check-up. Dhound also helped us with management issues. For example, now we have regular security checklist sessions and manage our risks.

Happy with the service and the report, it was great and from my understanding we've already taken action on some of the previously dismissed items you shed the light on. All staff I have dealt with were very helpful.
