Your network is the foundation of your entire security posture. I assess, harden, and monitor your network infrastructure — from perimeter defenses to internal segmentation — so vulnerabilities are found and fixed before attackers exploit them.
Comprehensive network security from the perimeter to the data center.
Audit and optimize your firewall rule sets to eliminate overly permissive rules, identify shadow rules, and align with least-privilege principles.
Design and implement secure Cisco network configurations including ACLs, spanning tree, VLAN segmentation, and routing protocol hardening (CCENT certified).
Deploy, configure, and optimize Blue Coat proxy solutions for web filtering, SSL inspection, and content control. BCCPA & BCCPP certified implementation.
Implement network segmentation to contain breaches, separate sensitive systems, and reduce your blast radius. Proper VLAN design, DMZ architecture, and access control.
Deploy and tune intrusion detection and prevention systems to identify and block malicious traffic patterns in real time.
Secure your SD-WAN deployment with proper security policies, encrypted tunnels, and integration with cloud security platforms like cloud security platforms.
Map your entire network topology — devices, connections, traffic flows, and boundaries. Identify every entry point and critical asset.
Analyze firewall rules, device configurations, and network architecture for security gaps, misconfigurations, and policy violations.
Rank findings by risk and business impact. Focus on the changes that provide the most security improvement with the least disruption.
Implement security controls, harden configurations, and deploy monitoring. Full change documentation for your team.
Verify controls work as designed. Set up ongoing monitoring and alerting. Provide runbooks for your operations team.
Most networks have hidden vulnerabilities — overly permissive firewall rules, unpatched devices, poor segmentation, or default credentials. A network security assessment reveals your true risk posture with evidence-based findings, not guesswork.
Network segmentation divides your network into isolated zones so that a breach in one area cannot spread to others. It's one of the most effective controls for limiting the damage from ransomware and other attacks that rely on lateral movement.
I have broad experience with enterprise firewalls and can work across most major vendor platforms. My strongest expertise is with Cisco, Blue Coat, and cloud security platforms-based architectures, but the security principles I apply are vendor-agnostic.
Yes. I help secure SD-WAN deployments by designing proper security policies, encrypted tunnels between sites, and integration with cloud security platforms like cloud security platforms to ensure consistent policy enforcement regardless of where users connect from.
