Good performance! @sunnyvalley Sensei plugin benchmarks it for 50 devices (next generation capabilities)! Unfortunately this model is only available to buy in Brazil...

Super stuff. 💯💯 Building a small SOC station is a dream in progress.

I must say, using @opnsense together with @sunnyvalley sensei and @AdGuard gets you so close to enterprise level firewall and network security and visibility. Very ideal to SMEs with limited budget and your home network.

@opnsense is really an affordable #nextgenerationfirewall with the #sensei engine to know what is going on in #smallbusinessowner’s IP networks.
