Core Security and Networking Applications

• Next-Generation Firewall and Router

  pfSense delivers a next-generation stateful firewall engine with advanced rule management, geoip blocking, alias support and granular controls that adapt to any network topology. Its modular design allows seamless integration of intrusion prevention and deep packet inspection modules.

• Virtual Private Network Services

  • OpenVPN

    OpenVPN integration provides secure remote access through SSL tunneling, multi factor authentication support and high throughput encryption.

  • IPsec

    Industry standard IPsec tunnels offer site-to-site connections with automatic key exchange, dead peer detection and excellent interoperability with commercial routers.

  • WireGuard

    Modern and lightweight WireGuard support delivers lightning fast key swapping, minimal codebase and razor sharp performance for mobile and stationary clients.

• Intrusion Detection and Prevention

  Choose between Snort or Suricata packages for signature based detection, protocol anomaly checks and real time blocking of suspicious flows. Both engines support custom rule feeds, automated updates and rich logging.

Advanced Networking Tools for Elite Control

• Load Balancing and Failover

  Distribute traffic across multiple WAN links or server pools. Intelligent health checks ensure uninterrupted availability even under heavy load or link failure.

• Traffic Shaping and QoS

  Guarantee bandwidth for mission critical services. Define queues and prioritization policies for VoIP, video streaming and business applications with real time monitoring of queue status.

• Dynamic DNS

  Automatic domain updates keep remote access alive when public IP addresses change. Support for multiple providers and custom update intervals.

• Captive Portal

  Implement guest authentication, splash pages and usage limits for public wifi. Custom HTML templates and voucher systems transform open networks into secure, controlled environments.

Monitoring, Analytics and Reporting

• RRD Graphs

  Visualize traffic, CPU load, memory usage and interface statistics with detailed time series graphs. Historic data empowers capacity planning and trend analysis.

• System Logs and Alerts

  Centralized logging with remote syslog support, email notifications and integrated dashboard filters simplify troubleshooting and security audits.

• Real Time Network Traffic Monitoring

  Live connection tables, top talkers and protocol breakdowns provide deep insight into active sessions. Drill down by interface, host or port in an intuitive web UI.

Premier Third Party Packages

• pfBlockerNG

  Comprehensive IP and DNS based blocking against ads, trackers, botnets and malicious domains. Customizable block lists, geoip blocking and automatic updates.

• Squid Proxy

  High performance caching proxy with ACL controls, transparent mode, SSL bumping and granular content filtering for web acceleration and security.

• ACME Certificate Automation

  Lets Encrypt integration automates certificate issuance and renewal for HTTPS and VPN services. Zero downtime deployment and email notifications on renewal failures.

• Traefik Proxy

  Dynamic reverse proxy with automatic discovery of backend services and integrated Lets Encrypt support. Ideal for microservices and container based infrastructures.
