Hello Linda,

While the idea seems great, I fail to immagine how this could be done.

I mean, a sandbox that is basically an environnement isolated from the rest of the client operating system and it need to exist at client side

This highly depends on the client operating system and the "sanboxing" options available. (Most probably a virtual machine on the client computer)

For example Windows provides a sandboxing environnement, but it would need the user to access the mail from the sandbox. I have some doubt about automatically starting a sandbox from the main OS while clicking on a link.

But maybe I don't fully understand the feature request.

Kind regards.

Hey Sebastien! You are understanding correctly :)

I'm not sure how it would be implemented either, but I wanted to ask if it was something that possibly could be done. 

I have a few customers who are concerned about it. They said almost every insurance policy asks if a company is doing sandboxing.

Might their reference to "sandboxing" be talking about sandboxing of incoming attachments and the like? In that case Cyren Premium Antispam does sandboxing I believe.

Hey Kyle! One of my customers in particular asked about URL isolation. For example, if an email comes in with a URL, they would want to test the link in isolated (sandbox) environment before actually opening it in the email just in case it contains a virus or malware that somehow made it through the AV scanners etc..

That particular scenario should be covered by a combination of ClamAV/Cyren as they should both do URL scanning:

For ClamAV I believe the config option you'd be looking for is: 

With the proper mix of AV/AS setup though you can achieve that level of security. 

Thanks Kyle. I'm going to pass this on to them.

Very welcome :)
