The SonicWall Essential Protection Service Suite (EPSS) for NSa Series is a reliable, cost-effective solution for organizations that need comprehensive threat protection without sandboxing or zero-day detection. This suite includes Gateway Anti-Virus, Intrusion Prevention, Anti-Spyware, Application Control, and Content Filtering Service, as well as 24x7 technical support and firmware access. EPSS provides a foundational layer of security designed for NSa environments where uptime, visibility, and compliance are critical, but advanced services like Capture ATP may not be required. Whether you're protecting a branch, data center, or headquarters, EPSS ensures your firewall is fortified with SonicWall's trusted core services. Note: Compatible with SonicWall NSa models (e.g., NSa 2700, NSa 3700, NSa 4700). Always confirm the model and license duration.
