Gen 8 TZ and NSa Firewalls: Simplifying Secure Public Internet Access for Users and Devices

In today’s hybrid, multi-cloud world, organizations must offer fast, reliable and secure internet access for employees, guests and public-facing services, without compromising security or compliance. As networks become more distributed, protecting every connection becomes a necessity. That’s why we’re excited to announce the launch of our latest innovations: the SonicWall TZ280, TZ380, TZ380W, TZ480, TZ580, TZ680, NSa 4800 and NSa 5800 firewalls with centralized, cloud-native management, all backed by a complimentary cyber warranty.

SonicWall and the latest platforms address this with a holistic, integrated solution for Secure Public Internet Access for Users and Devices, combining on-prem and cloud-managed security capabilities.

Why Gen 8?

In today’s unpredictable global economy, small- to medium-sized businesses (SMBs) are the backbone of communities and innovation, making up 90% of companies worldwide and employing over half the global workforce. But they’re also increasingly the target of cybercriminals. Simultaneously, the world is more connected than ever. With over 5 billion internet users and 95% of websites now encrypted, secure (HTTPS) traffic has exploded, driven by remote/hybrid work, cloud apps, streaming and AI-powered services. This shift demands a new kind of firewall: one that delivers always-on, high-performance protection, but is also affordable, easy to manage and built for today’s hybrid, cloud-first world.

Compared to previous generations and competitors, Gen 8 Firewalls offer:

• Higher throughput and IPS performance
• Persistent performance even with security features enabled
• No additional license required for stateful HA sync
• AI-powered insights and automation
• Easy migration from legacy SonicWall platforms
• Cyber warranty included at no extra cost
