The event source matters more than the feature list
If a product cannot reliably identify the source behind an authentication failure, it cannot safely block it. Collector quality, normalization and application-specific handling are foundational.
Built-in support will never cover everything
Real customers run software the vendor has never seen. Custom Monitors therefore need to be a first-class feature rather than a future roadmap item. Event channels and log files should be able to feed the same policy model as built-in collectors.
Blocking must remain explainable
An administrator should be able to answer which monitor saw the activity, what events matched, which username was involved, which threshold fired, why the duration was chosen and when the block will end.
Successful logins matter too
Early brute-force tools focused almost entirely on failures. Real operations need context. Guard can classify successful authentication for trusted-source learning and reset-on-success behavior where appropriate.
Central management becomes mandatory
One host is easy. A fleet needs enrollment, policy, license visibility, shared settings, monitor distribution and event visibility. Datacenter exists because per-server administration stops scaling.
Security intelligence ages
GeoIP, blacklists, external reputation and product compatibility require maintenance. Security software that keeps running but stops receiving meaningful updates can create a false sense of protection.

Current Scantide detail
Current Scantide source: Scantide Guard Product & Server Security GuidesUse Scantide Guard assessment reporting to review system health, security posture, software, CVEs, lifecycle, services, disks, firewall and other server evidence.
Current Scantide source: RDP Brute Force Protection for Windows ServerWindows Security Event ID 4625 is a common failed-logon source. Guard also supports other trusted authentication evidence depending on the configured collector.
Current Scantide source: Custom Security Log Monitoring & Automatic IP BlockingNot every application deserves a hard-coded collector. Guard Custom Monitors let administrators teach Guard how a trusted event channel or log file represents authentication failures, successful logins and source IP evidence.
Current Scantide source: Scantide Guard Product & Server Security GuidesExtend Guard beyond its preinstalled collectors. Turn Windows Event channels and application log files into Guard security evidence with custom parsers, failed/successful authentication classification, per-monitor policies and Datacenter-managed distribution.
Current Scantide source: Scantide Guard for Windows ServerScantide 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.

Historical source · JufCorp: Securing Windows Server with a baseline security1. Make sure all of your software is updated with all security patches. This includes the Windows operating system but also Adobe, Java,Office and any software really. This reduces the risk for so called 0day attacks or your server being compromised by software bugs.
