All CIS versions have CIS premium as IS core. You only get the technical service, Trust connect (which you can get for free at their forums.), maybe backup online storeage and some warranty. You don't get that much more from the pro. Complete version include some of the free stuff, such as Comodo Backup with 10GB online storage.
