What is penetration testing?
Penetration Testing (in other words Ethical hacking) is a simulation of a real-world cyber-attack. Our goal during the project is to discover the weaknesses and prevent the risks of a potential intrusion.
We do everything the real hacker does, but with good intentions.
Types of penetration testing we provide
Internal Penetration Testing
Assess the internet-facing systems and define exploitable vulnerabilities and misconfigurations that expose data or allow unauthorized access
Social Engineering
We test your defences by simulating real-world attacks to gain access into the organization through remote access. We use email phishing to check the most common attack scenarios as well as scenarios developed specifically for your organization
External Penetration Testing
Assess an organization’s internal systems and applications. Define how a hacker can move throughout the network and how deep he can dive. Test data exfiltration and MITRE coverage of your SOC/MDR
Red Teaming Attack Simulation
Get holistic assessing all areas of the organization, across people, processes, and technology, to determine how these factors can be abused and exploited by a malicious actor
Web Application Penetration Testing
Test for possible data leakage points and vulnerabilities according to OWASP top 10. Check if source code and API are written according to best practices and if customer data is safe. Test your WAF solution
IoT Security Assessments
Assess the security of the device. We try attempting to exploit the embedded firmware, control the device by bypassing or injecting unsolicited malicious commands, or modifying data sent from the device
Mobile Application Penetration Testing
Testing for platform-specific vulnerabilities. An application security audit inside the Android/iOS environment

Penetration testing methods

Black Box Penetration Testing
We simulate outsider threats having strictly limited knowledge of your network and no information on the security policies, network structure, software, and network protection used

Gray Box Penetration Testing
We simulate insider threats with minimum knowledge of the customer’s environment. Includes escalating privileges, installing custom-crafted malware, or exfiltrating faux critical data

White Box Penetration Testing
We identify potential points of weakness by using admin rights and access to server configuration files, database encryption principles, source code, or architecture documentation
Penetration testing is the best crash test for your business
Not just a list of vulnerabilities, but also how they can be exploited
Scanners can’t think. Automated services give only just a list of vulnerabilities. They look for known, defined, and predictable patterns.
Scanners create an illusion of safety.
We do everything manually. We try to find logical defects, rights separations, defects in architecture and design, etc. We dive deeper to understand how hackers can exploit chains of vulnerability to access your sensitive data. We put together all findings to give you comprehensive information on how to fix security issues.
Fill in security gaps to meet international quality standards
We follow TOP penetration testing methodologies to define existing security vulnerabilities so we can provide the best service for you to find. That’s why we can guarantee that results meet the highest quality requirements.
