Our Clients Choose Us For

Extensive Vulnerabilities Coverage

Quality pen-testing extends beyond OWASP and covers more sophisticated threats.

We align our testing strategy with recent cybersecurity studies & attack vectors.

Security and Coding Background

White-box testing for critical system components requires code-level involvement.

Hence, we blend our cybersecurity expertise with decades in software programming.

Regulations Compliance Expertise

Pentest is often a part of a larger project related to regulatory compliance.

We ensure compliance with ISO 27001, SOC 2, NIS 2, DORA, C5, GDPR, and more.

Remediation Assistance

We not only prepare a vulnerability report but also consult on remediation steps.

Including free retesting of the areas at risk to make sure everything is fixed.

Application Penetration Testing

Web Application Penetration Testing

Companies build their security strategies relying on independent web app testing to safeguard an unbiased overview of their security posture. Our security team is ready to help you assess your application security, whether you are preparing for regulatory compliance (e.g. C5 or DORA) or a new product launch.

We combine knowledge of industry-leading standards (e.g. OWASP Top 10, OWASP Testing Guide, CWE Top 25) with experience in software delivery to identify breaches beyond common exposures, including flaws in the app logic, authorization, and authentication flows. Our approach amplifies manual work with automated tools to shorten the project timeframe by up to two weeks while ensuring coverage of all app security aspects.

Mobile Application Penetration Testing

Mobile applications, whether native or cross-platform, require additional security testing outside traditional web application approaches. This step allows covering mobile-specific risks and requirements, such as proper session management, protection against reverse engineering, and more.

Our team follows the OWASP Mobile Application Security Testing Guide (MASTG) to ensure comprehensive coverage and tailors our testing approaches to fit the application’s platform, be it Android or iOS. Additionally, we always work through the OWASP Mobile Top 10 list of vulnerabilities to address the primary risks in mobile apps, including improper credential usage, insecure authentication, and inadequate privacy controls.

Infrastructure Penetration Testing

Internal & External Network Testing

It is always a challenge to secure something you are not aware of. So, gaining insight into the actual conditions of your external perimeter and intranet is crucial. Especially, when it comes to finance, healthcare, retail, and logistics, as they handle sensitive data and rely heavily on robust IT infrastructures.

Our network testing specialists assess infrastructure safety from two different viewpoints: a regular employee with a standard level of access to the network and an external hacker trying to break inside the corporate network. It helps us efficiently identify and mitigate breaches in the IT infrastructure, including overlooked elements like demo and test environments, test databases, shadow IT assets, etc.

Cloud Assessments

The continuous trend toward cloud adoption, including multi-cloud and hybrid cloud approaches, significantly increases a company’s attack surface and adds a layer of complexity for security teams, as they must establish and monitor consistent compliance controls across various platforms.

Our team conducts assessments of cloud-based assets across major platforms, including AWS, GCP, Microsoft Azure, and Oracle, leveraging the Center for Internet Security (CIS) Benchmarks tailored for each cloud provider. As a result, you receive a report mapping your compliance status with CIS requirements and prioritizing areas of mitigation based on the risk score.

Advanced Penetration Testing Services

Red Team

Red Team engagement is perfect for organizations that wonder how well they would manage a real-world attack. Controlled simulations of external cyber-attacks give a detailed company overview from an attacker’s perspective, revealing the true security posture and the efficiency of established security controls.

Our Red Team service consists of three stages. First, we do recon activities to discover leaked information and gather intel on your company profile using OSINT techniques. Next, we exploit vulnerabilities to identify weaknesses in your network perimeter and critical assets. Finally, we deliver a report with prioritized remediation advice, enabling you to address the most critical risks first.

AI (LLM) Security Testing

AI opens a variety of opportunities for businesses. Chatbots, virtual assistants, and data tools have already tangibly enhanced business efficiency. Yet, these innovations brought a new category of privacy and security risks, such as system takeovers and data breaches, that require specialized security evaluation and cannot be fully addressed by traditional penetration testing approaches.

Our team uses the OWASP Top 10 for Large Language Model Applications to address critical LLM risks, including prompt injection and permission issues. We identify potential weaknesses and provide complete guidance on how to properly implement preventive measures and build comprehensive security processes for your AI solution.
