Network Security Appliance and Solution

The era of information explosion

As the worldwide number of internet-connected devices growth explosion, Edge computing is becoming conclusive in managing the vast amounts of data being generated and supporting innovative, targeted applications IoT, SD-WAN, uCPE, FWA, 5G cellular, Wi-Fi 6, SASE, Cybersecurity, and artificial intelligence enablement. These technologies will continue to be critical areas of focus in the next few years.

Information technology and operational technology are converging, accelerated by virtualization, and consolidated for software-defined everything environments.
When NFV is combined with an SD-WAN deployment such that one piece of customer premises equipment can support multiple functions (e.g., firewall, IDS/IPS, load balancing, WAN acceleration) in addition to the core SD-WAN capability. This is particularly attractive for smaller branches, where the enterprise might not have much local IT support. Portwell provides Commercial off-the-shelf (COTS) products built for SD-WAN and uCPE to help companies stay connected. SD-WAN enables various deployment options, including complete cloud, hardware, and hybrid-based solutions. SD-WAN technology has also been widely adopted for providing easy management and consolidation of branch offices from central locations.
