SonicWall Firewall & Cloud Secure Edge Review
SonicWall is an American cybersecurity company headquartered in Milpitas (San Jose), California, founded in 1991. It is privately owned by Francisco Partners and Elliott Management following a 2016 acquisition from Dell. SonicWall serves approximately 500,000 businesses across 215 countries and territories through its network of 21,000+ channel partners, primarily MSPs and MSSPs. Its product portfolio includes next-generation firewalls (TZ series for SMB, NSa series for mid-enterprise), Cloud Secure Edge (ZTNA and SSE, built on its January 2024 acquisition of Banyan Security), SD-WAN built into NSa firewalls, managed detection and response (MDR via Solutions Granted acquisition, November 2023), and managed security services. In July 2024, SonicWall launched Cloud Secure Edge — rebranding and integrating Banyan Security's ZTNA capabilities — enabling zero-trust identity-based access from its full firewall and appliance line.

What Netify Thinks
SonicWall's strategic transformation under CEO Bob VanKirk (since 2022) is focused on converting its massive installed base of legacy hardware firewall customers to cloud-native services — bundling Cloud Secure Edge ZTNA with every new firewall to ensure the cloud-native capability is always available. The 700% year-over-year cloud-native business growth in 2024 suggests this conversion strategy is gaining traction with the MSP channel.
Strengths
- ~500,000 customers in 215 countries: SonicWall's installed base is one of the largest in the NGFW and SMB security market. This scale provides a conversion opportunity as the company transitions customers from legacy hardware to cloud-native services.
- Cloud Secure Edge — ZTNA now bundled with every firewall: Following the Banyan Security acquisition in January 2024, SonicWall integrated Banyan's cloud-native ZTNA capabilities into SonicOS and now bundles Cloud Secure Edge with every new firewall. This strategy ensures SonicWall's entire installed base has access to zero trust access capabilities without additional procurement.
- MSP/MSSP-first channel strategy: SonicWall's 21,000+ channel partners — heavily weighted toward MSPs and MSSPs — are the primary route to market. The company has invested in partner programme features including month-to-month agreements and no mandatory minimums, making it MSP-friendly for recurring managed security services.
- Gen 8 hardware platform — August 2025: SonicWall launched Gen 8 TZ and NSa series firewalls in August 2025, featuring high port density (up to 10 ports for TZ380/580), expandable storage up to 512GB, and updated SonicOS with Cloud Secure Edge integration — providing a refreshed hardware platform for the installed base upgrade cycle.
Weaknesses
- September 2025 cloud backup security incident: SonicWall disclosed in September 2025 that its cloud backup service experienced a security incident. The company completed its investigation and reported resolution in November 2025. Enterprise buyers evaluating SonicWall for cloud services should request details on the security enhancements implemented.
- SD-WAN is a firewall feature, not a platform: SonicWall's SD-WAN capability is built into its NSa series firewalls as a feature rather than offered as a standalone enterprise SD-WAN platform. This limits its applicability for complex multi-vendor, multi-transport SD-WAN deployments compared to dedicated SD-WAN platforms.
- Not in Gartner MQ for SD-WAN or SASE: SonicWall is not evaluated in the Gartner Magic Quadrant for SD-WAN or SASE Platforms. Buyers using Gartner MQ as a primary shortlisting tool will not find SonicWall represented in network transformation evaluations.
- Cloud Secure Edge maturity: Cloud Secure Edge (ZTNA/SSE) was launched in July 2024, based on the January 2024 Banyan Security acquisition. As a relatively newly integrated product within SonicWall's portfolio, enterprise buyers should carefully evaluate deployment maturity and reference site availability for large-scale ZTNA deployments.
Verdict: SonicWall is best suited to SMB, mid-market, and MSP-served organisations that need affordable, well-supported NGFW security with integrated SD-WAN for branch connectivity and are beginning to extend to cloud-native Zero Trust access via Cloud Secure Edge — particularly those already in the SonicWall ecosystem looking to leverage their existing firewall investment for ZTNA without a platform change.

Frequently Asked Questions
What is SonicWall Cloud Secure Edge?
SonicWall Cloud Secure Edge is SonicWall's Zero Trust network access (ZTNA) and Security Service Edge (SSE) capability, built on the technology acquired from Banyan Security in January 2024. It was launched in July 2024 and is integrated into SonicOS, meaning every new SonicWall firewall now ships with Cloud Secure Edge capabilities built in. Cloud Secure Edge enables identity-based, zero-trust access for users connecting from any device and location to corporate resources, replacing traditional VPN with more granular, application-level access controls.
Does SonicWall offer SD-WAN?
SonicWall includes SD-WAN capabilities within its NSa series firewalls as a built-in feature. This provides basic SD-WAN functions including dynamic path selection, WAN failover, and cloud connectivity optimisation for SMB and mid-market branch deployments. However, SonicWall does not offer a standalone enterprise SD-WAN platform comparable to Cisco Catalyst SD-WAN, Fortinet Secure SD-WAN, or Versa Networks. Organisations requiring advanced multi-transport SD-WAN with sophisticated application-level steering, WAN optimisation, or carrier-grade management should evaluate dedicated SD-WAN platforms alongside SonicWall firewalls.
Is SonicWall suitable for UK deployments?
Yes. SonicWall has a substantial UK presence through its channel partner network, with many UK-based MSPs and MSSPs reselling and managing SonicWall products. UK SMBs and mid-market organisations are well served by SonicWall's TZ and NSa firewall series through UK-based partners. UK enterprise organisations should evaluate whether SonicWall's feature set meets their requirements, noting that Cloud Secure Edge for ZTNA is a more recently launched capability (July 2024).
What happened with the SonicWall September 2025 security incident?
In September 2025, SonicWall disclosed that its cloud backup service experienced a security incident. The company launched an investigation and completed it, reporting resolution with strengthened cyber resilience measures in November 2025. The incident affected cloud backup services specifically rather than core firewall or network security products. Organisations using SonicWall's cloud backup services should verify the current security posture of those services with SonicWall's UK sales or support team.
