Firewall & Network Security
SonicWall firewall architecture with high availability, multi-site design, and advanced segmentation — pre-configured before deployment and documented for long-term management.
Overview
The right hardware, properly configured, for your environment.
Firewalls are the network's entry point — controlling inbound and outbound traffic across every location. RSystems has standardized on SonicWall appliances after evaluating hardware from Cisco, Juniper, and Fortinet, selecting them for the right combination of performance, reliability, and value at the price points mid-market organizations actually operate in.
SonicWall's TZ series suits small to mid-sized offices; the NSA series addresses larger environments requiring redundancy features. RSystems prefers paired firewall deployments with active/standby configuration and continuous synchronization — failover occurs in seconds if the primary unit reboots or the WAN link fails.
Capabilities
- VLAN segmentation and guest network isolation
- Policy-based routing for multi-WAN and multi-location environments
- Site-to-site and SSL VPN configuration
- Content filtering for public or guest WiFi environments
- Firewall rule documentation and ongoing policy management
- High availability active/standby configuration with automatic failover
- Remote management and scheduled firmware updates via cloud console
Our Approach
How RSystems approaches firewall engagements.
01
Assessment
Review your current hardware, configuration, and requirements — including site count, uptime requirements, and budget constraints.
02
Strategic Planning
Hardware selection and architecture design — right-sized for today and scalable for your growth trajectory.
03
Pre-Configuration
SonicWall units configured and tested at RSystems before deployment to minimize on-site time and risk.
04
Implementation
On-site deployment with minimal operational disruption.
05
Documentation
Complete records of firewall rules, routing configuration, and VPN settings.
06
Ongoing Support
Firmware updates, policy adjustments, and manufacturer escalation when needed.
