WatchGuard Endpoint Security Release 18 is now available!

We’re excited to announce WatchGuard Endpoint Security for Servers, a new infrastructure protection solution available globally. Endpoint Security for Servers brings advanced, resource-aware protection to the most critical systems in your customers’ environments. Designed specifically for server workloads, this new solution provides dedicated defenses that maintain uptime, minimize performance impact, and meet modern compliance standards.

Key Highlights

• Purpose-built protection for Windows and Linux servers: Engineered for physical, virtual, and cloud workloads with persistent protection for mission-critical systems.
• AI-driven behavioral analysis and exploit prevention: Uses machine learning and behavior analytics to block ransomware, exploits, and fileless attacks in real time.
• Zero Day Vulnerability Protection: Zero-Trust Application Service blocks all unverified processes before they run, using a deny-by-default model backed by AI and global threat intelligence.
• Lightweight, resource-aware agents optimized for server performance: Minimal CPU and memory use ensures uptime and stability for critical workloads.
• Unified management with endpoint protection in WatchGuard Cloud: Manage endpoint and server protection from WatchGuard Cloud with shared policies and reporting.

What it Means for You

Servers remain one of the highest-value targets for attackers. WatchGuard Endpoint Security for Servers is resource-aware by design, using lightweight agents that deliver robust protection without disrupting business-critical processes. Advanced exploit prevention, vulnerability management, and behavioral detection work together to protect Windows and Linux servers, whether running on-premises or in virtual and cloud environments.

With this release, you can deliver consistent, enterprise-grade protection across endpoints and servers, simplifying management while expanding managed service opportunities.

We’re excited to offer an Early Access Program for our newest endpoint solution, WatchGuard Endpoint Security Prime. This Early Access Program is available in North America (US and Canada) from October 1 to December 31, 2025.

What Is Endpoint Security Prime?

WatchGuard Endpoint Security Prime delivers advanced, AI-powered endpoint detection and response (EDR) in a single, streamlined solution at a price point competitive with basic next-generation antivirus (NGAV)-only solutions. This makes true endpoint defense accessible to every organization and helps organizations strengthen defenses without adding complexity or cost.

Traditional endpoint protection tools are built for yesterday’s attacks. Endpoint Security Prime raises the bar by unifying multiple capabilities into one lightweight, cloud-managed package:

• Next-Generation Antivirus (NGAV): Blocks known and emerging malware threats.
• Endpoint Detection and Response (EDR): Provides full visibility, automated response, and deep behavioral analysis.
• Attack Surface Reduction (ASR): Hardens devices by controlling access, blocking exploits, and reducing exposure.

It’s enterprise-grade protection that’s smarter, simpler, and accessible to every organization.

Why This Matters

Today’s threats are faster, more adaptive, and designed to evade prevention-based defenses. That’s why endpoint security needs to go beyond detection; it needs to predict, respond, and learn.

Endpoint Security Prime does exactly that by combining automation, continuous visibility, and self-learning AI to identify and stop attacks before they spread. Managed and deployed through WatchGuard Cloud, our new solution reduces overhead and gives teams confidence that every endpoint is protected without the cost or complexity of traditional enterprise tools.

Get Started

WatchGuard Endpoint Security Prime is available now in North America. Please contact your Channel Account Manager to learn more. 

Because supporting your transition matters, we’re extending our support timeline one more time.

We previously extended the End of Life (EOL) date for endpoint protection on legacy Windows and macOS operating systems to June 30, 2025. Today, we're announcing another full year of extended support — now through June 30, 2026.

We understand that migrating from older platforms takes more time — and we’re here to support you. This extra year gives you more flexibility to plan, transition, and secure your environments.

Affected Operating System Versions:

• Windows: Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008 (Server 2008 R2 remains supported)
• macOS: Yosemite, El Capitan, Sierra, High Sierra, and Mojave

What Happens on June 30, 2026:

• Licenses on devices running the above OS versions will be automatically removed
• These systems will no longer be eligible for license reassignment

Once licenses are removed, endpoints will have all protection features disabled, lose access to Collective Intelligence, stop receiving signature updates, and all assigned tasks will cease.

To stay protected, plan your customers’ migration well in advance and complete it before the deadline.
