Generally, your auth provider (assuming setup correctly) should be one of the most secure components of your internet-exposed setup. That being said, vulnerabilities can and do occur. Adding a combination of Crowdsec, OWASP CRS, other ModSecurity rulesets, and/or fail2ban will add a degree of migitation of potential exploits by blacklisting known bad actors/active bad behavior.
Above all, you should have a plan to keep aware of updates to your publicly-exposed software and be able to deploy those updates in a timely fashion.
