Failed-login blocking with fleet management

A Windows and Linux Alternative to Fail2ban

Fail2ban is widely used on Linux. Scantide Guard approaches the same core problem from a broader Windows-and-Linux operational model, with centralized management, richer server collectors and shared Guard policy.

Capabilities

What this Guard workflow covers

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

Is Scantide Guard a fork of Fail2ban?

No. Guard is a separate Scantide product with its own collectors, policy model, UI and Datacenter management.

Why consider Guard on Windows?

Windows administrators often need RDP, Windows Security Event, IIS/RDWeb and SQL Server failed-login handling that fits naturally into Windows operations.

Can Fail2ban and Guard coexist?

Technically overlapping security tools can coexist, but administrators should avoid competing firewall automation and duplicate rules. A controlled migration or clearly separated responsibilities is safer.
