Keep enforcement close to the workload
Each Guard server observes its local evidence and can enforce through the local Windows or Linux firewall. That keeps protection autonomous even if the central service is temporarily unavailable.
Centralize policy and visibility
Datacenter provides a common place for policy, enrollment, configuration, security-event visibility and licensing across managed servers.
Share intelligence without duplicating it
Managed Guards can use Datacenter as the central path for external reputation caching and Global Reputation publishing, avoiding duplicate outbound queries and duplicate submissions.
Distribute Custom Monitors centrally
Organization-approved monitor definitions can be managed in Datacenter and distributed to enrolled servers while keeping locally authored monitors distinct.
Design for offline segments
Highly secured networks may allow a Guard server to reach Datacenter but not the Internet. Central services should therefore be able to broker licensing, policy and intelligence where practical rather than assuming every server has direct outbound access.

Current Scantide detail
Current Scantide source: RdpGuard Alternative for Windows & Linux Server ProtectionA single Guard can protect its own server with local policy and local firewall enforcement. Organizations with multiple systems can add Scantide Guard Datacenter for shared policy, fleet visibility, licensing and coordinated reputation services.
Current Scantide source: SSH Brute Force Protection for LinuxScantide Guard does not need to attack, exploit or brute-force a service to decide that repeated hostile activity deserves action. Collectors observe evidence already generated by the server, normalize it into a common event model, then apply explicit thresholds, allowlists, exceptions and enforcement policy.
Current Scantide source: Scantide Guard for Windows ServerMonitor definitions can be packaged, reviewed and distributed. Datacenter can centrally distribute managed monitors while locally authored monitors remain distinct.
Current Scantide source: Scantide Guard for LinuxEvents from Custom Monitors feed the same deterministic Guard decision model and local firewall enforcement used by the built-in SSH and web collectors.
Current Scantide source: Scantide Guard for LinuxScantide Guard can use successful authentication evidence from supported built-in collectors and Custom Monitors to recognize trusted administration sources, reset or contextualize active failure history where appropriate, and reduce unnecessary blocking without weakening the deterministic protection model.
Field experience from the archive
Historical source · JufCorp: Securing your server environment - Part III - Operating systemsIn many environments, local firewalls are disabled out of pure laziness. "We can't be bothered troubleshooting why SQL traffic doesn't work .." Have local firewalls enabled , enable logging so you can easily find what's going on. If you're in a shared environment you'll also get alerted about noisy neighbors . Local firewalls also enables you to utilize a brute force prevention software and have those attacks mitigated, no matter where they come from. If you want, I'll happily help you out with getting a brute force prevention software in place.
Historical source · JufCorp: Securing your servers, users and customers onlineEnforce an Account Lockout Policy and enforce complex password. Yes, people will hate you but they will hate you even more if someone actually succeeds in hacking your users data. Have a look at the link above about Account Lockout Policies though. Do not have local users more than necessary on the Exchange Server itself.
