Speedster IT WatchGuard Gold Expert Verdict

If you’re an MSP, IT director, or cybersecurity lead seeking a firewall that balances performance, manageability, and threat intelligence.

Firebox is a serious contender. It’s particularly well-suited to UK businesses navigating hybrid work, compliance, and budget constraints.

Why UK Businesses Are Switching to WatchGuard Firebox

At Speedster IT, we’ve spent over two decades securing networks for businesses across London, the UK, and globally.

MSPs are moving to WatchGuard for:

• Stronger breach prevention
• Simplified multi-tenant management
• Transparent licensing and predictable pricing
• Better integration with RMM and PSA tools

Speedster IT has helped dozens of MSPs and IT providers migrate from SonicWall to WatchGuard with minimal disruption and maximum security uplift.

As a WatchGuard Gold Partner, we’ve seen first-hand how Firebox firewalls outperform legacy solutions, especially in light of recent high-profile breaches like the ones affecting SonicWall and CrowdStrike.

Is WatchGuard Firebox More Secure Than SonicWall?

Yes, and here’s why.

WatchGuard Firebox is built around a multi-layered security model that includes AI-powered threat detection, zero-trust access, and real-time threat correlation via ThreatSync.

Unlike SonicWall, which recently suffered a breach exposing cloud backup configurations, WatchGuard has maintained a strong track record of proactive threat prevention and transparent incident response.

How Does WatchGuard Handle Cloud Backups Differently to SonicWall?

Unlike SonicWall’s cloud backup system, which was compromised in 2025. WatchGuard Firebox configurations are encrypted, locally stored by default, and can be securely backed up via WatchGuard Cloud with role-based access controls and multi-factor authentication (MFA).

This significantly reduces the attack surface and mitigates the risk of unauthorised access to sensitive configurations.

Which Firewall Is Better for UK SMEs — SonicWall or WatchGuard?

For UK SMEs, WatchGuard Firebox is the superior choice. It offers:

• Simplified management via WatchGuard Cloud
• Built-in compliance tools for GDPR and Cyber Essentials
• Scalable models for growing businesses
• UK-based support through trusted partners like Speedster IT

SonicWall’s recent breach has raised serious concerns about its suitability for compliance-driven environments.

Can WatchGuard Firebox Replace SonicWall in Hybrid Networks?

Absolutely. Firebox supports on-premises, virtual, and cloud-native deployments, making it ideal for hybrid infrastructures.

Whether you’re running Azure, AWS, or a private cloud, Firebox integrates seamlessly, with centralised policy management and automated threat response across all environments.

Does WatchGuard Offer Better Breach Response and Support?

Yes. WatchGuard is known for rapid disclosure, detailed incident reporting, and partner-first support.

In contrast to SonicWall’s delayed communication during its breach, WatchGuard maintains clear SLAs, 24/7 global support, and real-time threat intelligence updates, all critical for MSPs and IT teams managing client networks.

Is WatchGuard Firebox Compliant with UK Data Protection Laws?

Yes. Firebox supports GDPR compliance, Cyber Essentials, and ISO 27001-aligned controls. Features like data loss prevention (DLP), application control, and audit logging help UK businesses meet regulatory requirements with confidence.

Is WatchGuard Firebox a Good Fit for GDPR and UK Cyber Essentials?

Yes. Firebox includes pre-configured policy templates, encryption enforcement, and access controls that align with both GDPR and Cyber Essentials. It also supports automated compliance reporting, making audits faster and easier.

Does WatchGuard Firebox Offer Better Visibility and Threat Response?

Yes. Firebox integrates with ThreatSync, WatchGuard’s XDR platform, to provide real-time visibility, automated incident scoring, and cross-layer correlation. This enables faster detection and response compared to SonicWall’s siloed alerting systems.

How Does WatchGuard’s ThreatSync Compare to SonicWall’s Cloud Security?

ThreatSync offers:

• AI-driven threat scoring
• Automated remediation across endpoints and firewalls
• Unified visibility across the attack surface

SonicWall’s cloud security tools lack the same level of integration and automation, making WatchGuard a smarter choice for proactive defence.

Can WatchGuard Firebox Prevent Configuration File Theft?

Yes. Firebox uses encrypted configuration storage, MFA-protected access, and role-based admin controls to prevent unauthorised access — a key weakness exploited in the SonicWall breach.

Is WatchGuard More Transparent About Breach Incidents?

Yes. WatchGuard has a proven history of timely, detailed disclosures and partner-first communication. Their incident response playbook prioritises clarity, containment, and collaboration exactly what UK businesses need in a crisis.

If you’re a UK business or MSP concerned about SonicWall’s recent breach, or simply looking for a more secure, transparent, and scalable firewall solution WatchGuard Firebox is the answer.
