I architect and maintain PureHosts' entire network infrastructure — from core routing to edge security. Every packet, every connection, zero compromise.
PureHosts relies on a fully redundant network architecture with multiple upstream providers, enterprise switches, and low-latency routes. I manage VLAN segmentation, load balancing, and failover mechanisms to ensure zero downtime.
Our data center uplinks are monitored 24/7, and I continuously optimize routing policies using BGP to deliver the fastest response times to users worldwide.
Core competencies to keep PureHosts connected and protected
VLANs, inter-VLAN routing, static/dynamic routing (OSPF, BGP), and QoS policies.
Zone-based firewalld rules, iptables, nftables, and advanced ACL management.
Site-to-site VPN, WireGuard, IPsec tunnels for secure remote management.
Prometheus SNMP exporters, Cacti, Nagios, and real-time packet analysis with tcpdump.
Designing and maintaining the entire network topology, including public/private subnets, routing tables, and failover paths.
Implementing and auditing firewall policies, blocking malicious traffic, and preventing DDoS attacks at the network edge.
Managing open ports (80, 443, 22, 21, 25, 143, 993, 995) and ensuring only authorized services are exposed.
Proactive monitoring, latency optimization, and incident response to guarantee 99.99% network availability.
