VAITHEX is a malware-prevention tool from PRESENSE Technologies GmbH that protects systems against threats arriving in files. It scans files with at least two antivirus scanners (extendable to four), blocks files by MIME type or extension, and cleans them through normalisation, including removing Office macros, JavaScript and other active content from Office and PDF files. Files can optionally be converted, for example from DOCX to PDF. It is installed as a network application, controlled through an asynchronous REST API, supports batch processing and logs via syslog. The company also makes the PROVAIA and JANUS data-gateway appliances, which check removable media.
PRESENSE Technologies GmbH is based in Hamburg, Germany. VAITHEX is installed by the customer, so files are processed on the customer's own systems and no hosted service is involved. The company states that it develops its PROVAIA appliance entirely in Germany and has signed the "IT Security made in Germany" initiative. For European organisations, a self-installed file-sanitisation gateway keeps incoming files inside their own infrastructure and jurisdiction.
