Xiarch Firewall Security Review is a managed security service that evaluates firewall, switch, and router configurations to identify vulnerabilities, configuration flaws, and compliance gaps. The service addresses requirements from regulatory frameworks including PCI DSS, ISO 27001, HIPAA, SOX, and RBI cybersecurity standards. The service examines both external and internal network security infrastructure to detect deprecated rules, insecure protocols, and misconfigurations that may allow unauthorized network access. Reviews can be conducted remotely or on-site, either as standalone assessments or bundled with other managed compliance services. Xiarch's methodology includes information gathering, enumeration, vulnerability scanning, penetration testing, and comprehensive reporting. The team uses tools including Nipper, RAT, and proprietary analytical techniques to identify firewall security issues. Service delivery can be scheduled on a regular basis (quarterly or bi-yearly) or aligned with security upgrades and application releases. Some clients run scanners independently and provide raw data to Xiarch for detailed analysis. Deliverables include vulnerability assessments with impact analysis, remediation recommendations, and technical solutions. The service provides test-over-test evaluation to help organizations track security improvements over time and validate that firewall configurations effectively protect business data and information assets.
