any recommandations like basic setup for security for antispam etc? or any free addons to help step up security for the website? (best if can dont have addons)
If your site is recent you shouldn't be bothered by SPAM often, which is my case, so in the meantime you can trust basic XenForo functions like Captcha systems.
Regarding forum security, I haven't heard of any issues there so I don't think you should worry about that at this time.

User groups are XenForo's primary method of assigning roles to the users of your forum. This allows you to assign permissions, titles and other customizations to users.
