RDP Brute Force Protection for Windows Server
Internet-facing RDP services are continuously probed. Guard watches trusted Windows authentication evidence, correlates repeated failures and can block the source IP locally before it continues hammering the server.
Uses Windows authentication evidence rather than packet guessing
Supported as part of the Guard monitoring, policy or enforcement workflow.
Configurable failure threshold and time window
Supported as part of the Guard monitoring, policy or enforcement workflow.
Temporary and repeat-offender blocking
Supported as part of the Guard monitoring, policy or enforcement workflow.
Immediate-block options for selected high-confidence usernames
Supported as part of the Guard monitoring, policy or enforcement workflow.
Allowlist and trusted-host safeguards
Supported as part of the Guard monitoring, policy or enforcement workflow.
Source IP enrichment and country context
Supported as part of the Guard monitoring, policy or enforcement workflow.

- Central fleet visibility with Datacenter
- Audit trail explaining why the IP was blocked
Designed around observable server evidence
Scantide 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.
The result is intended to be understandable by an administrator: which source IP was seen, which collector reported it, which rule or threshold was reached, what action Guard took, and when a temporary block is due to expire.
Standalone when you need it. Centralized when you grow.
A 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.
Frequently asked questions
Which Windows event is commonly used for failed logons?
Windows Security Event ID 4625 is a common failed-logon source. Guard also supports other trusted authentication evidence depending on the configured collector.
Will Guard block my administrator IP?
Administrators should configure allowlists and trusted networks before aggressive blocking. Guard policy is intended to preserve explicit allowlist precedence.
Does Guard expose RDP to perform its checks?
No. Guard observes local server evidence. It does not need to probe or authenticate to RDP itself.
