What is Firewalla and what does it do?

What Is Firewalla?

Firewalla was developed and built by 4 co-workers Melvin Tu, Jerry Chen, Annie Lu and Michelle Ma with the goal of making ” Cyber Security Simple, Affordable and Powerful for everyone” Firewalla was funded through “Kickstart” in 2017 and again through Indiegogo” in 2018. They are located in San Jose, California.

Firewalla is a very compact little device that plugs into your router and once plugged in will provide protection from internet and network threats. It acts as a Firewall that can block and detect any external access to your devices such as, Smart TVs, Baby monitors, or any other devices you may have connected.

Firewalla is basically a Security all-in-one that will protect your entire network, by monitoring suspicious Apps and blocks access to malicious links on all of your devices. Firewalla also has built-in AdBlocking features and Parental controls to prevent access to inappropriate sites.

  2. This is a very good device. First time hearing about it though. It’s good you gave us the names of those who made this device and also told us how it works. For me, I would go for the red because I connect with less than 50 people. It’s good to always have protection when one is going to be using the internet and since I’ll be working from home, this is the best protection I can get.
