Security Scans
We perform automated security scans on our managed and unmanaged servers at regular intervals. The purpose of these scans is to detect potential security risks and vulnerabilities—particularly those arising from publicly accessible server services and open network ports—at an early stage and to alert you to possible threats.
Monitored Services
Our security scans monitor the following services:
| Service | Protocol | Port |
|---|---|---|
| SSH | TCP | 22 |
| DNS | TCP | 53 |
| MySQL | TCP | 3306 |
| Redis | TCP | 6379 |
| OpenSearch / Elasticsearch | TCP | 9200 |
| Kibana | TCP | 5601 |
| AMQP | TCP | 5672 |
| PostgreSQL | TCP | 5432 |
| Plesk Apache2 (HTTP) | TCP | 7080 |
| Plesk Apache2 (HTTPS) | TCP | 7081 |
| Microsoft RDP | TCP | 3389 |
| Microsoft SQL | TCP | 1433 |
| NFS | TCP | 2049 |
| SMB | TCP | 445 |
| Prometheus | TCP | 9090 |
Secure Server
We offer automatic firewall rules for all monitored services. Click “Secure Server” to see a preview of the new firewall rule.
Please note that by default, the new rule applies to all source IP addresses. If you want to exclude specific IP addresses from the rule, add a firewall rule afterward that allows the desired traffic.
Add an Exception for a Service
If you want to disable the check for a specific service, you can use the Ignore Warning button to add an exception for that service.
Optionally, enter a comment so you can later recall why the check was disabled.
Clicking Add Exception permanently disables the check and hides the security warning for the server.
