Security is important when you are letting people log onto your system via Opensim. It is also very important to know that the code you are running is safe too. DreamGrid is the only Opensim server code that is digitally signed using Microsoft Authenticode so that any modifications can be automatically detected and stopped. I compile all the code personally, and sign it on one trusted machine that is virus scanned by a top-rated scanner.

The Outworldz web site is also digitally secured by Digicert, a top-notch Certificate Authority, so you are guaranteed you are getting the code from the real Outworldz web site and that it meets the highest standards for security. Outworldz gets an A rating from a well-known SSL test suite.

Both of the Dynamic DNS systems, the primary one at, and the backup in Europe, have been tested as meeting all modern DNS standards.A Rated security
