IT security tests

We offer comprehensive cybersecurity services compliant with international standards such as ISO/IEC 27001, NIST, and OWASP. Our team of certified experts with over 10 years of experience ensures a personalized approach and data confidentiality, delivering clear reports with practical recommendations.

IT penetration testing

We perform manual and automated security tests, identifying vulnerabilities. We check:
- web portals
- mobile applications
- IT infrastructure
- network services

We deliver a detailed report with recommendations to strengthen your security.

Vulnerability analysis

Using advanced tools (e.g., Qualys, Nessus, Rapid7, Burp Suite, OWASP ZAP, SonarQube, Snyk), we quickly detect vulnerabilities in:
- software code
- server and service configurations
- IT infrastructure
- web and mobile applications

Our analyses help minimize the risk of attacks.

Configuration audit

We check compliance with recognized standards, including ISO/IEC 27001, PCI DSS, NIST, CIS Benchmarks, as well as requirements arising from the NIS2 directive. Our audits help meet regulatory obligations and enhance cyber resilience.

Social engineering test

We test employees’ resistance to social engineering attacks such as phishing and psychology-based manipulations (e.g., reciprocity, liking). We simulate realistic scenarios to improve awareness and security.

Services

Security policy review

We assess whether an effective information security management process is in place within the organization. We assist in its implementation if it does not yet exist and conduct risk analysis related to IT processes. Our efforts support compliance with applicable regulations such as NIS2, GDPR, and ISO/IEC 27001.

Manual security testing

We simulate the actions of an experienced attacker to verify whether the implemented security measures are sufficient. We conduct tests of IT environments and network devices, as well as web applications and services. Our work follows the guidelines outlined in the OWASP Testing Guide, ensuring a comprehensive and reliable approach to security assessment.

Vulnerability scanning

We verify whether system and service configurations are secure, up-to-date, and aligned with industry best practices. Our work is based on recognized standards such as CIS Benchmarks, NIST, as well as requirements from ISO/IEC 27001, PCI DSS, and the NIS2 directive. We identify potential security gaps and risks arising from improper configurations and provide practical recommendations to eliminate them.

Social engineering tests

We conduct controlled social engineering tests that involve attempting to persuade employees to disclose confidential information, such as passwords, company data, or physical access to the facility.

Our work methodology

By using our services, you are guaranteed that the project will be assigned to professionals with the appropriate skills and experience. We also collaborate with independent experts, allowing us to flexibly tailor the team to the specifics and needs of each client. Our work is performed both remotely and on-site at the client’s premises.

Our team holds numerous industry certifications that confirm their high qualifications, including:
CISSP, OSCP, OSCE, CEH, eWPT

We conduct web portal testing using the OWASP Testing Guide, with particular emphasis on threats from the  OWASP TOP 10.

Mobile application testing is performed following the OWASP Mobile Security Testing Guide recommendations, taking into account the TOP 10 Mobile Risks

We carry out IT infrastructure and network services testing according to recognized standards such as:
PTES – Penetration Testing Execution Standard
OSSTM Manual – Open Source Security Testing Methodology Manual
NIST SP 800-115 – Technical Guide to Information Security Testing

Configuration audits are conducted based on recognized norms and regulations, including:
ISO/IEC 27001 – international standard for information security management,
PCI DSS – payment card data protection standard,
NIS2 – EU directive on network and information security,
CIS Benchmarks – configuration guidelines for systems and services,
NIST SP 800-53 / SP 800-171 – IT system security standards.

We help meet regulatory requirements, increase cyber resilience, and reduce risks arising from misconfiguration.

Why is testing IT security important?

The purpose of security testing is to identify vulnerabilities that may compromise the integrity, confidentiality, or availability of IT systems, applications, or services. Conducting such tests allows risks to be detected and eliminated before attackers exploit them.

Typical consequences of a successful attack include:

  • unauthorized content modification (e.g., announcements),
  • impersonation of an authorized user,
  • unauthorized data access,
  • full takeover of a system or device,
  • temporary service disruption (DoS or DDoS attack),
  • log wiping to erase traces of activity,
  • leakage of personal or financial data (e.g., GDPR, payment card data),
  • data encryption by ransomware and ransom demands,
  • manipulation of business data (e.g., altering balances in financial systems),
  • privilege escalation — access to data and functions beyond assigned roles,
  • installation of backdoors or malware enabling future access.

The most common targets for attackers are applications and services accessible externally (from the Internet). Due to their continuous availability, a security test performed by an anonymous individual can be conducted at any time.

Increasingly, organizations report that attacks are also originating from inside the infrastructure. This happens because employees are becoming more proficient with new technologies. To perform basic security tests, a mobile application installed on a device is often sufficient—without the need for specialized knowledge or equipment.
