On the security front, NETGEAR Armor offers real-time protection against hackers, though the trial is only 30 days. Automatic firmware updates add an extra layer of safety for your devices. However, it's not suitable for users with DSL services or those needing bundled voice services.

It is essential to verify compatibility with your ISP. The device is compact and lightweight, making it easy to place in any home setting.
