Application Penetration Testing

Application penetration testing is a key part of modern cybersecurity. The goal is to systematically identify, analyze, and verify vulnerabilities in software systems before attackers find them. These tests help prevent data leaks, reputational damage, and financial losses.

We test the security of web, mobile, desktop, and hybrid applications including APIs and source code. We use a mix of manual and automated testing based on methodologies such as OWASP Top 10, OWASP MASVS, and other standards.

The output is a technical report with detailed findings, risk ratings, and concrete remediation recommendations.

What is application penetration testing and why is it critical?

Application penetration testing is a key part of modern cybersecurity. The goal is to systematically identify, analyze, and verify vulnerabilities in software systems before attackers find them.

We test the security of web, mobile, desktop, and hybrid applications including APIs and source code. The output is a technical report with detailed findings, risk ratings, and concrete remediation recommendations.

Experience

Years of experience with penetration testing, red teaming, and offensive security.

Transparency

Ongoing communication and clear expectations at every step of the project.

Collaboration

Close cooperation with your team and clear, usable deliverables.

Professionalism

Maximum focus on ethics, quality, and security standards.

Testing process

Application penetration testing process

We start by defining goals and scope. This is followed by passive and active analysis of the target, identification of vulnerabilities, and verification of exploitability. We document findings carefully to minimize false positives.

Scope definition

We agree on goals, application types, and critical assets.

Analysis and weakness discovery

We run passive and active tests focused on real attacks.

Exploitability verification

We validate findings and prepare reproducible evidence.

Final report

We deliver a report with prioritized risks and remediation guidance.

Scope

Types of applications we test

We assess the full application stack including web, mobile applications, and APIs. Each type has specific weaknesses that we verify.

Web applications

We test authentication, injection flaws, server configuration, and session protection.

Mobile applications

We focus on encryption, backend communication, and API security.

API interfaces

We verify authorization, data handling, and business logic in endpoints.

Desktop applications

We analyze sensitive data storage, permissions, and server communication.

Source code audit

Static and manual code review uncovers logic flaws and weak validation.

Service comparison

Application penetration testing vs. source code audit

Both methods complement each other. A penetration test validates a running system from an attacker perspective, while a code audit finds issues before deployment.

Aspect	Application penetration testing	Source code audit
Focus	Real application operation, configuration, and data.	Logic and security flaws in code.
Methodology	Manual testing and attack simulation.	Static and manual analysis of source files.
Timing	After deployment or when the application changes.	Ideally before production deployment.
Output	Report with impact and remediation priority.	Code findings with recommended fixes.

TESTIMONIALS

What Our Clients Say About Us

Ultima Payments

"The decision to collaborate with Haxoris for the penetration testing of our web application was an excellent choice. Thanks to their professional approach, thorough testing, and outstanding communication, we were able to identify and eliminate multiple vulnerabilities. Their detailed final report provided us with a clear overview of our application's security status and specific recommendations for its protection. I can wholeheartedly recommend Haxoris to any company - their services are of a high professional standard, and the results exceeded our expectations."

Digital Systems

"Professional services, client-oriented approach, we would order again :)"

Amerge

"The team has approached penetration testing professionally and impartially, while keeping an open line with our DevOps, frontend and backend developers to ensure proper isolation of production environments. The level of testing and subject-matter expertise was impressive, even compared to other world-class companies in the industry we've worked with. The depth of vulnerability testing and the findings clearly outlined our strengths and areas for improvement, helping us increase our security standards even further."

Piano

"We chose Haxoris to perform penetration testing of our web applications in accordance with ISO 27001 and PCI DSS standards. Their approach was focused on our business needs, and we also appreciate their client-oriented attitude and flexibility."

Frequently asked questions (FAQ)

01 How long does penetration testing take?

The duration depends on the size and complexity of the environment. A small web application can take 3-5 days, while a full network test can take 1-3 weeks. At the start, we provide a time estimate and scope of work.

02 How much does penetration testing cost?

The price depends on scope and complexity. A basic web application test can start in the hundreds of euros, while larger networks or cloud environments cost more. After a consultation, we will prepare a non-binding quote.

03 How often should a penetration test be done?

Ideally at least once per year. We also recommend a test after major changes - launching a new application, migrating to the cloud, or updating infrastructure.

04 What do I receive after the penetration test?

You receive a detailed report with an executive summary, technical findings, risk ratings, and remediation recommendations. We also offer a follow-up meeting to explain the results.
