About SonicWall

SonicWall is a unified cybersecurity portfolio that helps SMBs, MSPs, and IT teams consolidate network, endpoint, cloud, and threat response across hybrid environments. SonicWall sells firewalls, endpoint security, a Security Service Edge platform, managed detection and response, and a management console that ties them together.[1]

SonicWall delivers cybersecurity solutions for organizations ranging from small businesses and distributed enterprises to MSSPs managing thousands of customer environments. SonicWall describes its protection as aimed at healthcare, education, local government, finance, manufacturing, and retail. SonicWall also offers on-premises, cloud-based and as-a-service options, so buyers can deploy what suits their architecture.[4][7][8]

On the network side, SonicWall TZ series firewalls are designed for the needs of SMBs and branch locations. For distributed enterprises, SonicWall TZ Series, NSa Series, and NSsp Series firewalls, paired with Network Security Manager (NSM), give a single point of control for thousands of enforcement points. SonicWall delivers Secure SD-WAN through TZ, NSa, and NSsp firewalls. Firewall security services apply to Gen 7 and Gen 8 firewall platforms.[7][9][10]

Organizations can manage endpoint protection themselves or add SonicSentry MDR for 24/7 managed detection and response. SonicWall also offers Capture Client, which is built on SentinelOne and delivers endpoint detection and response integrated with the SonicWall ecosystem.[11][12]

Cloud Secure Edge is SonicWall's Security Service Edge (SSE) platform. Cloud Secure Edge covers the full security stack from one platform: ZTNA, SWG, CASB, and DNS Security. For remote access, SonicWall Secure Mobile Access (SMA) 1000 Series and Cloud Secure Edge deliver both VPN and Zero Trust Network Access (ZTNA). SonicWall also supplies VPN clients, including NetExtender for Windows and Linux users.[1][7][13][14]

On the managed side, SonicSentry MDR and SonicSentry MXDR combine SonicWall telemetry with expert analysts who hunt, triage, and contain threats around the clock. SonicWall says that SonicSentry MXDR unifies monitoring of endpoint, cloud, and network, where correlated telemetry catches complex, multi-stage attacks a single layer would miss. SonicSentry MDR for SonicWall Endpoint Security is part of the Cysurance embedded warranty program.[7][11]

SonicWall Unified Management gives IT teams and MSPs a single console to manage, monitor, and respond across firewalls, switches, endpoints, and Cloud Secure Edge. Sami is SonicWall's AI-powered assistant that brings administrative guidance, solution building, and product support into a single conversational experience.
