"Powerful All-in-One Security with Clear Visibility and Easy Policy Management"

5/5

What do you like best about Arista NG Firewall?

All-in-one security: Firewalling, web filtering, intrusion prevention, antivirus/malware protection, application control, VPN, and related functions are all managed from a single platform.

Easy policy management: Policies and rules can be created based on users, devices, applications, websites, traffic types, and other attributes, instead of relying only on IP addresses and ports.

Visibility: Dashboards, reporting, and traffic insights help answer questions like, “Who is using what, and what is happening on the network?” Review collected by and hosted on G2.com.

What do you dislike about Arista NG Firewall?

Advanced troubleshooting can still demand deeper expertise. While the interface makes everyday tasks fairly approachable, diagnosing less common routing, inspection, application, or performance issues may still require substantial networking knowledge. Review collected by and hosted on G2.com.

"Easy to Use and Comprehensive Firewall Solution & More"

4.5/5

What do you like best about Arista NG Firewall?

Untangle NG Firewall is easy to deploy and use. You can expand functionality by purchasing plugins for only what you want. Licensing is simple as it is per device for all services. You can bypass devices to save licenses (for example: for IoT devices or printers bypassing Content Filtering). Review collected by and hosted on G2.com.

What do you dislike about Arista NG Firewall?

Content Filtering can be problematic when a website is flagged to multiple categories or when categories include diverse or uncategorized content, as you'll encounter blocked pages or false-positive alerts. Since licensing is done per device, you must have enough for the maximum number of clients you could have connected, so content filtering guest Wi-Fi, for example, could require a large investment.
