Four products, each with its own manual. GeoIP and Fail2Ban also ship inside the Odoo Host Manager. Blocklist is sold on its own.
Hosts multiple Odoo instances as Docker containers on one Linux server, and gives you one place to create, configure, back up, secure and monitor them.
Answers where an address is, and keeps its MaxMind GeoLite2 databases up to date itself. It knows nothing about access rules: which countries a caller allows is that caller’s policy.
Brute-force protection as a service: the fail2ban daemon and a management API in one container. The products it protects push their own jails into it, because they are the ones that know what their logs mean.
Checks a mail address, its domain and the client's IP address for sign-up and contact forms, against your own entries and public lists of throwaway domains and abusive networks it keeps up to date itself. It answers; what the form then does is the form's own policy.
