Secure communication and transmission of data across your network is critical to business. The SonicWALL TZ 170 SP is a high-performance, multi-layer network security platform that provides businesses, telecommuters and small office networks with constant access to critical data. Should the primary broadband connection go down, the TZ 170 SP ensures continuous uptime for VPN connectivity by automatically failing over to either a second WAN connection or an integrated analog modem. Once the broadband connection has been re-established, the TZ 170 SP detects the restored connection and automatically fails back, ensuring the best possible connectivity. In addition to its automated failover and failback capabilities, the TZ 170 SP integrates real-time gateway anti-virus and intrusion prevention capabilities for protection against viruses, worms, Trojans and other malicious threats. And, with built-in anti-spam protection and support for SonicWALL’s Content Filtering Service, the TZ 170 SP enhances productivity and network utilization.
