Common scenarios
For IT teams replacing an existing firewall, protecting a new office or branch, or giving people secure access from outside the office.
Firewall replacement
The current appliance is reaching end of life, is out of subscription, or no longer keeps up with the internet connection.
New office or branch
A new site needs perimeter protection, and often a site-to-site VPN back to head office.
Remote access
People working outside the office need VPN access to internal applications and files.
Multi-site networks
Several locations that should run consistent security policies and be managed centrally.
What to consider
The details that shape the right option. Include what you already know in your requirement.
Internet and WAN bandwidth
Connection speed usually drives sizing more than headcount. Each model publishes firewall and threat-prevention throughput — with security services enabled, throughput can be lower.
Users, devices and growth
How many people and devices sit behind the firewall today, and what you expect over the life of the appliance.
Sites and site-to-site VPN
How many locations need to connect, and the site-to-site VPN tunnel count each model supports.
Remote-access users
How many people connect remotely, and whether IPsec VPN or SSL-VPN clients are needed. Both have published per-model limits.
Security subscriptions
Gen 8 SonicWall appliances need an active subscription for full threat prevention, management and support — for example Secure Connect or the Advanced Protection Security Suite (APSS).
High availability
Whether a site needs a second appliance for failover, so hardware and licensing are quoted to match.
Ports, Wi-Fi and PoE
Interface and SFP requirements, and whether an integrated Wi-Fi or PoE model suits a small site.
Current environment
The firewall, ISP links and VPNs in place today, and anything that has to keep working through the changeover.
Approaches
Common ways to meet this requirement. The right fit depends on your environment.
