New SonicWall NSa 3700: The Latest Next-Generation Firewall for Medium Enterprises

Medium enterprises are increasingly faced with budget constraints and a shortage of cybersecurity experts among their IT staff. At the same time, network traffic continues to rise … as does the number of online transactions …  and the number of connected devices, including IoT devices.

This increase in new potential threat vectors has driven an increase in just about every form of attack, with emboldened cybercriminals launching increasingly sophisticated attacks such as zero-days and ransomware — many of which evade traditional perimeter defenses.

But despite this increase in risk, organizations are more reliant than ever on business continuity to ensure the continual availability of information and services provided across their network.

To meet these challenges, IT directors need a highly reliable next-generation firewall (NGFW) — one that can not only can scale to support millions of connections, but also scan them for threats over multi-gigabit speeds without compromising performance. It also must be cost-effective, easily manageable, and capable of handling high bandwidth and support multiple networks and clouds.

Introducing the SonicWall NSa 3700: A Generation 7 NGFW with high port density and low cost of ownership

The SonicWall Network Security Appliance (NSa) 3700 NGFW features high port density, including multiple 5 and 10 GbE ports. NSa 3700 protects mid-size networks with comprehensive integrated security services like malware analysis, encrypted traffic inspection, cloud application security and reputation services. It also supports centralized management with a truly intuitive single-user interface, significantly improving operational efficiency.

SonicWall NSa 3700 runs on the latest SonicOS 7.0.1 and includes advanced networking features such as HA/clustering, SD-WAN, dynamic routing, and virtual routing and forwarding. It combines validated security effectiveness and best-in-class price performance in a single rack unit appliance.

In short, medium enterprises can now get the performance, networking and security capabilities they need from their NGFWs without breaking the bank.
