How is Visual Guard .Net supposed to impact my application? Is the runtime integrated to each copy of my application? could this make it bigger? Do I need a more powerful server if I secure a Webform application?To install Visual Guard .Net on the developer machine, you need about 50 MB. In the database you need a few Mo when you install VG. The size of the repository will grow depending on the number of end users, of applications, Permissions and Roles you will declare. It also depends on your auditing str...
I need to plan capacity for Novalys SQL Server Repositories. If I have 5,000 users for a large application, how large should I expect the Repository size to increase?The number of users is not the only criteria to determine the size of the repository. This size also depends on the number of applications, Permissions and Roles you will declare. It also depends on your auditing strategy (the more events you log, the larger the repository). As for user accounts only, you can expect the repository size to incre...
Which method do you use to encrypt the data stored in the repository?We use algorythm SHA256.Visual Guard .NET - Version 2.7.802.29

We are looking for a single sign-on solution for a legacy Oracle app. Can Visual Guard secure Oracle forms? ThanksHello, yes Visual Guard can secure Oracle forms using the VG server. You would write code in your code to call the VG server to know if a user is authenticated yes/no, if he is in a role, or has a permission.
Hello, we use Anti-Piracy SHK Sentinel with our application. Can VG secure an application using Anti-Piracy SHK Sentinel ?We are not familiar with Anti-Piracy SHK Sentinel, so the best is to perform an integration test with on af our consultants. It seems Anti-Piracy SHK Sentinel is not an obfuscator tough, and it only encrypts the executable. If Visual Guard can access the non encrypted version of the application, everything should work smoothly. Visual Guard .Net needs to access the code to be able to cr...
We would like to authenticate and authorize users in a WPF application and in our WCF layer. The WCF layer is hosted on IIS and can have direct access to the sql-server. What is the performance of Visual Guard who uses reflection compared to using the built in SQL-membership and sqlroleproviders in .Net.It's hard to compare, since these 2 solutions operate on 2 completely parts of an application: SQL-membership and sqlroleproviders manage roles and permissions on DataBase objects, whereas Visual Guard ma...
If we buy the current version of Visual Guard do we need different consoles to support different versions of .Net. (Your web site says it supports 2, 3, and 3.5). Just wanted to be sure that I can use security with my 2.0 .net application and a newly developed .net application using 3.5 will also be supported. Do we all use the same assemblies or do you incorporate different version of assemblies in your .net application?The same copy of Visual Guard (based on the current version) will support your 2.0 / 3....
Does Visual Guard .Net work with application built using Microsoft's SCSF?Yes we do support applications build with SCSF. The way we secure them depend on the type of application you are developing.

How well does the VISUAL GUARD scale? Visual Guard has been designed to support a large volume of registered and concurrent users. * In the case of an MVC application, you basically don't have to change your infrastructure to run Visual Guard, whatever the number of users.
