Tumbleweed products were used to block security threats, protect information, and conduct business online. Tumbleweed provided solutions for inbound and outbound email protection, secure file routing, and identity validation that allow organizations to conduct business over the Internet. Tumbleweed offered these solutions in three product suites: MailGate, SecureTransport, and Validation Authority. MailGate provides protection against spam, viruses, and attacks, and enables policy-based message filtering, encryption, and routing. SecureTransport enables customers to safely exchange large files and transactions without proprietary software. Validation Authority determines the validity of digital certificates.
