Tunnel saved us from our employees stealing data from regular emails. We feel secure on our internal communications.

As a CPA, we send tax returns to our clients with large attachments. Our clients love our private email server with Tunnel and the best part is, no size limit on the attachments. Recommend this service to any accounting firm. It's secure, cost effective and easy to use. No junk mails or spam.
