Of course. But it's just another layer to the onion. Pfblockerng, Crowdsec, Fail2Ban, wireguard....layers.
Most likely it's fine. Though it's not terribly difficult to set up some flavor of VPN so you're not exposing 22 at all outside your network. Personally I use Wireguard.
This may be the completely wrong place to be asking. But, has anyone ever seen any sort of DIY LED sign, remotely configurable sort of project? I'm thinking a sign that can sit on my desk at the office that if I end up working remotely that day I can update it to reflect that to my coworkers (I get a lot of visitors per day from different departments asking questions) so they know they can still contact me via Teams? Apologies if this isn't the right place for this.
