MSPs supporting larger customer environments usually run into this challenge: customers want faster networks, more encrypted traffic inspection, and stronger resiliency, but they do not want a security stack that becomes harder to deploy, manage or license.
WatchGuard is giving MSPs a clearer path into larger firewall opportunities without asking them to leave the platform model they already use.
The company is positioning Firebox M4850, M5850, and M6850 as higher-performance options for partners and IT teams that need to scale firewall capacity without shifting to a more complex operating model. The appliances are now available through WatchGuard’s global partner network.
The new models extend WatchGuard’s Firebox line into higher-capacity environments where security is no longer limited to a branch office or network edge. WatchGuard said the appliances support native 25G and 100G connectivity, include redundant power supplies and hot-swappable fans as standard, and use centralized management through the company’s Unified Security Platform and WatchGuard Cloud.
Three new Firebox models
The new Firebox series includes three appliances: M4850, M5850, and M6850. WatchGuard describes the M4850 as an entry point into higher-performance deployments, the M5850 as a fit for sustained performance in campus and core environments, and the M6850 as the highest-capacity model for high-growth and data center edge use cases.
That model spread gives partners a more defined path for customers who are moving beyond traditional midmarket firewall requirements. A customer may start with branch-level or midrange appliances, but as it adds users, locations, cloud applications, encrypted traffic and higher-bandwidth links, the firewall can become a bottleneck. In those cases, MSPs often face a choice between pushing an existing platform beyond its comfort zone or introducing an enterprise firewall architecture that may be harder to manage at scale.
WatchGuard is arguing that these appliances reduce that jump. The company said the new rackmount series keeps policy enforcement, deployment and management tied into the broader WatchGuard platform rather than requiring teams to learn a separate operating model.
Built for faster, more demanding networks
WatchGuard said the appliances include high-speed network integrations for native 25G and 100G connectivity. The company also said the systems incorporate an industry-standard OCP 3.0 expansion bay, which WatchGuard described as a first for a firewall platform. That expansion bay is intended to support 100G networking now and allow for future expansion as network needs change.
A WatchGuard spokesperson told ChannelE2E that the performance gains are tied to the new hardware architecture, but the broader value for MSPs is that customers can scale without changing how they operate.
“The performance gains are driven primarily by new hardware architecture,” the spokesperson said. “At the same time, these appliances remain part of the WatchGuard Unified Security Platform, so customers gain greater performance and scalability without changing tools, management workflows, or licensing models. For MSPs, the value is not just a speed upgrade. It is a way to help customers support more encrypted traffic, more concurrent sessions, and more demanding environments without adding enterprise-level complexity.”
The spokesperson said MSPs can frame the refresh around performance, protection, and room for growth, rather than simply replacing a firewall appliance.
“The conversation can be more about restoring performance, maintaining protection, and creating space to grow, rather than just replacing a box,” the spokesperson said.
Firewall performance is not measured only by headline throughput. Customers want security services turned on. That means HTTPS inspection, VPN, intrusion prevention, anti-malware, application control and other services can all affect performance. When those features reduce throughput too much, partners may have to overprovision hardware or make difficult policy decisions.
WatchGuard said firmware improvements also contribute to service efficiency during full inspection, including UTM and HTTPS inspection. “We are faster and more efficient,” the spokesperson said.
Partner opportunity beyond the branch
The Firebox launch is also a channel expansion play. WatchGuard says it works with more than 25,000 MSPs protecting more than 1.5 million customers worldwide. The new appliances could help those partners pursue larger customers, including campuses, distributed enterprises, and data center edge deployments. That is a different sale from placing a firewall in a small office. Larger customers need more planning around throughput, segmentation, inspection, high availability, licensing, and lifecycle management.
The WatchGuard spokesperson said the company is targeting customers that have outgrown traditional midrange firewalls but do not want the cost or operational burden of enterprise platforms.
“The launch is aimed at the high end of the midmarket, school campuses, and distributed enterprise environments where customers have outgrown traditional midrange firewalls but do not want the cost or operational burden of enterprise platforms,” the spokesperson said. “WatchGuard is positioning these new models for use in headquarters, campus, and data center edge environments, where HTTPS inspection, resilience, and higher throughput matter most.”
For partners, this could create larger firewall refresh opportunities that previously may have pushed them outside the Firebox portfolio.
“For partners, that opens the door to larger firewall refreshes and higher-value opportunities that previously may have required them to step outside the Firebox portfolio,” the spokesperson said. “The clearest examples are customers facing encrypted traffic bottlenecks, larger campus-style deployments and organizations preparing for 2026 rackmount renewals.”
That is the real channel angle. MSPs can move upmarket only if the economics work. A higher-capacity firewall that still fits into an existing management platform can reduce training, support and operational costs. It can also help partners keep growing customers inside a familiar vendor ecosystem.
What makes this launch different
High-performance firewall refreshes are not unusual. Most major firewall vendors are pushing faster throughput, higher-speed ports, and stronger inspection performance as customer networks become more demanding.
WatchGuard’s argument is that this launch is not just about speed. The company is trying to combine higher firewall capacity with the management model partners already use.
“It’s the combination of performance, operational simplicity, and forward-looking hardware design within a single platform,” the WatchGuard spokesperson said. “These appliances introduce three clear performance tiers, native 25G and 100G connectivity, standard redundant power supplies and hot-swappable fans, while continuing to use the same Firebox platform and management model partners already know.”
The OCP 3.0 expansion bay is also part of that pitch. WatchGuard says it gives customers an industry-standard expansion path for future networking needs without forcing a move to a different firewall architecture.
“The OCP 3.0 expansion bay adds a future-ready, industry-standard expansion path to a firewall platform, which WatchGuard states is a first in the category,” the spokesperson said. “We are not just talking about higher speeds today; it is also about giving MSPs and customers a way to scale and adapt over time without moving to a different architecture or introducing the kind of complexity often associated with enterprise firewalls.”
The spokesperson added: “We are the most performant 1U rackmount firewalls in the market today.”
