Bitdefender Cloud Protection

Enabling Cloud Protection is recommended for all SpamTitan customers as it helps reduce the number of false positives for users and also improves detection rates, especially for zero-day malware - see more information below.

Follow these steps to disable/enable Cloud Protection (default: enabled).


When Cloud Protection is enabled, Bitdefender sends a subset of files anonymously to Bitdefender's servers to check against an online database. No personally identifiable information is transmitted as part of this process. See What Information is shared with Cloud Protection enabled?

Enabling Cloud Protection will help:

  1. Reduce false positives.

    If malware is detected by Bitdefender AV, information about the malware is submitted to Bitdefender cloud. This information includes files hashes, which allow Bitdefender to quickly check against their database of known clean files and verify if a file is a known clean file or not.

    If the file is present in the database, this is a false positive and will be suppressed by Bitdefender, reducing the number of false positives been seen by users. The information is also reported internally and the definition will be removed from future updates.

  2. Improve detection rates.

    To improve detection of new malware while keeping the number of false positives low, Bitdefender has implemented a 'hidden detections' feature in its engine which reports only to Bitdefender. This will help with the early detection of false positives and may also detect the zero-day malware targeting of specific users.

    Malware writers generally use third-party services to ensure their modified malware is not picked up by anti-malware engines. However, as hidden detections are not reported outside of Bitdefender, a malware writer is unaware that their malware may already have been uploaded and analyzed. This means Bitdefender may be able to detect the zero-day malware immediately once it is sent to a user.
