The SonicWall Essential Protection Service Suite (EPSS) for NSa Series offers a reliable, cost-effective layer of security for NSa firewalls. The suite includes Gateway Anti-Virus, Intrusion Prevention (IPS), Anti-Spyware, Application Control, and Content Filtering Service (CFS), plus firmware access and 24x7 technical support. EPSS is intended as a foundational protection package where advanced sandboxing or zero-day detection services are not required. It is suitable for protecting branches, data centers, or headquarters and supports NSa models (e.g., NSa 2700, NSa 3700, NSa 4700). Always confirm the model and license duration when selecting a license.
