Hallo, can you recommend a powerful, up-to-date ruleset? Price / month doesn't matter! I couldn't find the information on the opnsense wiki site. Thanks!
That depends on what you want to achieve. Protect client systems accessing the Internet? Protect servers? Both?
There are the Suricata and Zenarmor plugins available on OPNsense:

HTH,

Found it in the plugins... "Proofpoint ET Pro Ruleset" 750$/year.
Would you also recommend the sensei webfilter or is this IPS enough?
If this is a genuine question you might have missed the ET PRO telemetry offer... https://docs.opnsense.org/manual/etpro_telemetry.html
Price vs. sharing data is another thing, but the resulting rules are the same.
