What's New in SonicOS 8.2.2? Secure-by-Default Protection Meets Simplified Firewall Management

New Features Across GEN8 Hardware and the New NSv Virtual Firewall Lineup Strengthen Security While Reducing Administrative Overhead

SonicWall is pleased to announce the general availability of SonicOS 8.2.2 for GEN8 hardware appliances and the new NSv virtual firewall lineup. This release delivers essential security enhancements, operational improvements, and expanded platform capacity, reinforcing SonicWall's commitment to simplifying firewall management while strengthening defenses against evolving threats.

What Is New in SonicOS 8.2.2?

SonicOS 8.2.2 introduces major features designed to reduce deployment friction, improve visibility, and enhance the user experience across all GEN8 platforms.

Security Services Enabled by Default

Every new GEN8 appliance now automatically enables Gateway Anti-Virus, Anti-Spyware, Intrusion Prevention, Botnet Filtering, and Geo-IP Filtering at registration, with no manual configuration required. This secure-by-default posture eliminates a common security gap in SMB and branch deployments, ensuring every registered firewall is protected from day one.

Let Us Encrypt Your Traffic

SonicOS 8.2.2 now supports automated SSL/TLS certificate issuance and renewal via Let's Encrypt (ACME v2 protocol). The firewall requests, installs, and automatically renews certificates before expiry with zero administrator intervention, reducing the operational burden of certificate management across hundreds of appliances.

Two-Factor Authentication for Global VPN Client

Remote access users can now use TOTP-based two-factor authentication when connecting via Global VPN Client 5.0.0.2008. Support for industry-standard authenticator applications, including Google Authenticator and Microsoft Authenticator, makes MFA enforcement straightforward without requiring a separate authentication platform.

Intelligence-Driven Threat Blocking

Administrators can now import SHA-256 hash lists from threat intelligence feeds, up to 500,000 entries, directly onto the firewall. Files matching a known malicious hash are blocked in transit and logged for audit, providing security and MSP teams with an additional layer of enforcement alongside endpoint tools.

Stronger Credential Protection

Passwords for administrators and local users are now stored using one-way cryptographic hashing (bcrypt) rather than reversible encryption. Configuration backups no longer expose recoverable credentials, significantly improving resilience against extraction attacks.

Enhanced Platform Capacity

The TZ80 entry-level appliance now supports up to ten concurrent SSL VPN users, and NSv instances now support up to 500 groups, giving growing organizations more headroom before requiring a hardware upgrade.

A More Intuitive Management Experience

Based on direct customer feedback, SonicOS 8.2.2 delivers a series of usability refinements that make day-to-day administration faster and less error prone. Add, Edit, and Delete controls are now consistently placed across all rule and policy pages. App Control sorting has been refined to persist user selections. VPN tunnel status now updates in real time. Log entries link directly to signature settings for faster troubleshooting. These improvements align with NSM 4.3 terminology and navigation, creating a consistent experience across centralized and local management.

SD-WAN and New NSv Sizing

The maximum number of supported SD-WAN sites on GEN8 hardware has been increased, enabling larger branch deployments from a single hub. Additionally, three new NSv virtual firewall sizes, Small (2 vCPU, 2 GB), Medium (4 vCPU, 8 GB), and Large (8 vCPU, 16 GB), complement the existing NSv XS. All three deliver the complete GEN8 security stack and support VMware, Hyper-V, KVM, Proxmox, AWS, and Azure, allowing customers to right-size firewall capacity to actual workload requirements.
