Live Probing Data Targeting Windows and Exchange Servers

Last month, we blocked over 1300 malicious / unauthorized connections attempts from 13 countries targeting our infrastructure. Our systems detected this significant spike in internet probing activity targeting our Windows servers. Thanks to our real-time threat intelligence feeds, these connection attempts were identified immediately and blocked before they could do any harm.

Just as importantly, our continuous Server Threat and Health Monitoring confirmed that no penetrations occurred and all systems remained secure and fully operational.

This kind of activity often goes unnoticed. Many organizations are unaware of the constant background probing against their infrastructure—and in most cases, security teams only discover it after a compromise has already occurred, spread internally, and caused disruption and damage.

In this instance, two Messageware Security Solutions worked together seamlessly to detect, block, and validate the outcome in real time:

  1. Messageware Exchange Protocol Guard identified and blocked the malicious probes, automatically banning the offending connection attempts using live threat data feeds (see Table 1).
  2. Messageware Server Threat Guard continuously monitored multiple Windows servers and provided a consolidated dashboard view, confirming there were no security incidents related to this activity (see Table 2)

Let’s take a closer look at the two at-a-glance reports that were automatically delivered, keeping us informed without manual effort:

Table 1 highlights authentication attempts from known malicious IP addresses that were proactively banned. Notably, several of these attempts originated from cloud-hosted infrastructure. Platforms such as Azure, AWS, Google Cloud, and others are frequently leveraged for attacks due to how quickly resources can be provisioned—and because their domestic IP addresses often bypass basic geo-blocking.

Table 2 provides a consolidated view of the threat and health status across internal servers. At a glance, it confirms that systems remained healthy and risk-free, with no detected penetrations, exploits, or related security incidents during the spike in probing activity.

This is what proactive security looks like: detect early, block automatically, and verify continuously—without disruption.
