The SonicWall TZ series offers small to mid-size organizations and distributed enterprises the opportunity to experience the advantages of a comprehensive security solution that fulfills all their requirements. By incorporating high-speed threat prevention and software-defined wide area networking (SD-WAN) technology, along with a wide array of networking and wireless features, the TZ series provides a unified security solution that is easy to deploy, centrally managed, and comes at a low total cost of ownership.
Reassembly-Free Deep Packet Inspection (RFDPI): This high-performance, proprietary and patented inspection engine performs stream-based, bi-directional traffic analysis, without proxying or buffering, to uncover intrusion attempts and malware and to identify application traffic regardless of port.
Bi-directional inspection: Scans for threats in both inbound and outbound traffic simultaneously to ensure that the network is not used to distribute malware and does not become a launch platform for attacks in case an infected machine is brought inside.
Stream-based inspection: Proxy-less and non-buffering inspection technology provides ultra-low latency performance for DPI of millions of simultaneous network streams without introducing file and stream size limitations, and can be applied on common protocols as well as raw TCP streams.
Highly parallel and scalable : The unique design of the RFDPI engine works with the multi-core architecture to provide high DPI throughput and extremely high new session establishment rates to deal with traffic spikes in demanding networks.
Single-pass inspection: A single-pass DPI architecture simultaneously scans for malware, intrusions and application identification, drastically reducing DPI latency and ensuring that all threat information is correlated in a single architecture.
