Perimeter 81, a secure access service edge (SASE) and network-as-a-service provider, has introduced its Network Traffic Control (NTC) firewall-as-a-service (FWaaS) offering.NTC brings FWaaS-level security to an organization's cloud network perimeter, the company said. In doing so, it can help organizations securely scale and protect their expanding perimeters.IT teams can use NTC to create policies that apply to their Perimeter 81 cloud edge network and enforce network traffic control both inside and outside of their network, the company indicated. NTC lets these teams segment Layer 3 and 4 access based on user or group identity and create traffic filtering rules for network objects that include addresses, users, groups and services.NTC also leverages Perimeter 81 Zero Trust Network Access (ZTNA), Zero Trust Application Access (ZTAA) and DNS Filtering capabilities, the company stated. It uses network policy rules that provide granular control of how data flows at every layer.
