opnsense-plugin-crowdsec VS crowdsec

Yes. I would do this with CrowdSec instead. It just came out in a beta version for OPNsense. It's unique in the way that it protects a number of services against, for instance, bruto force attacks by using collaborative threat intelligence; all users shares basic information about who's attacking them and have. Download it here. For now it protects ssh and https on OPNsense (and various 3rd party services).

I am head of community at CrowdSec and as others already point out, there's already beta packages available here. Install it and tell about it on our Discord :-)

There's finally a port out for OPNsense. Get it here. By default it's able to protect ssh and web logins on OPNsense itself - but it's a full client so it can do much more if you want it. Or you can just install the bouncer port and have the agent running on a separate server if you have a more distributed environment. It's still in beta but it should work fine. If you have any problems, please ask in #-bsd on the CrowdSec Discord.

You can download it here. As I've said before, this is beta software. So if it blows up anything, you can't blame us :-) However, if you do run into trouble I suggest that you join our friendly Discord community (if you haven't already) and ask any questions regarding the port in #-bsd.

Hey we actually built the second part as a product. Its a modern revamp of fail2ban combined with crowdsourcing aspect to deliver an up-to-date blocklist of active threats. You can check it out at https://github.com/crowdsecurity/crowdsec

Today we are pleased to announce the launch of CrowdSec Engine 1.5 - this is a huge milestone for the project and one that would not have been possible without the help of this community. You can read see the full change log over on GitHub here https://github.com/crowdsecurity/crowdsec/releases

wget https://github.com/crowdsecurity/crowdsec/releases/latest/download/crowdsec-release.tgz server:> tar xzvf crowdsec-release.tgz https://github.com/crowdsecurity/crowdsec/releases/latest/download/crowdsec-release.tgz server: > tar xzvf crowdsec-release.tgz server:> cd crowdsec-v* && sudo ./wizard.sh -i

This tool crowdsec.net is really interesting to mitigate and enact defense systems for different scenarios.

You should check out https://crowdsec.net. More advanced, uses crowdsources cti to block attacks even before they happen. Also both nginx and captcha is supported. Disclaimer: I am head of community. Visit /r/CrowdSec or our Discord at https://discord.gg/crowdsec if you have questions :-)

Do I need something like crowdsec, or is WireGuard secure enough on its own?

Before falling too much in love with Fail2Ban try taking a look at https://crowdsec.net. Similar functionality but way more advanced (but easier to configure). New project that leverages the power of the crowd and shares information of attacks among users so they help each other out protecting themselves.
