Xiarch Network Penetration Testing is a professional security service that conducts simulated attacks on network infrastructure to identify security vulnerabilities before malicious actors can exploit them. The service employs ethical hacking techniques to assess both external and internal network security postures. The service includes external network assessment that evaluates perimeter defenses, routers, firewalls, and Intrusion Detection Systems (IDS) accessible from the internet. Internal network assessment simulates insider threats by attempting to access privileged information and compromise virtual and physical machines within the local area network. The assessment methodology follows a structured approach that includes scope definition, information gathering using OSINT tools, enumeration through automated scripts and tools, attack and penetration using both manual and automated security scans, comprehensive reporting with risk analysis, and discussion with remediation guidance. Deliverables include a detailed digital security evaluation report with remediation steps, security certificates after patch verification, and access to qualified security consultants holding industry certifications such as CHECK Team Member, CEH, ECSA, OSCP, CISA, and CISSP. The testing process incorporates industry standards including OWASP Top Ten and PCI Compliance requirements to identify both technical security vulnerabilities and business logic flaws.
