SUMo icon SUMo Software Update Monitor


SUMo (Software Update Monitor) keeps your PC up-to-date & safe by using the most recent version of your favorite software !
Unlike built-in auto update features, SUMo tells you if updates are available before you need to use your software.


  • Automatic detection of installed software
  • Detects required updates / patchs for your software
  • Detects required drivers update (requires DUMo)
  • Filter / authorize Beta versions (user setting)
  • Ignore list : only tracks software YOU want to track
  • More compatibility and less false positive than others Update Monitors (according to users feedback ;-)
  • Internationalization support
  • User-friendly interface (see Accessibility compliance assessment)
    SUMo PRO extra features :
  • Automatic self-update (PRO only)
  • Direct access to most software developer's web site (PRO only)
  • SUMo PRO does not download nor deploy updates for 3rd party software for increased security but leads you close to the genuine download links to keep user in full control
