Perimeter 81 is an Israeli network security service provider that offers a cloud-based cybersecurity experience platform, consolidating networking, security, and remote access within a single service. It uses the Secure Access Service Edge (SASE) model to provide a secure and flexible approach to defending sensitive networked resources. Perimeter 81's features include user management, network management, and network security services such as authentication, encryption, and DNS filtering. The company promotes its broader suite of converged networking services but also offers a subset of these features as a replacement for legacy VPN infrastructure. Twingate, on the other hand, delivers a modern approach to secure network access by establishing software-defined perimeters around every protected network, leveraging Zero Trust Network Access principles to eliminate vulnerabilities. Twingate's focus is on secure access control, offering a simple and easy-to-use administrative console, quick implementation within 15 minutes, and tiered pricing that includes a free option for individuals or small teams. Both Perimeter 81 and Twingate offer solutions to many challenges organizations face from legacy VPN technologies' increasing vulnerability to cybercrime, but they differ in their approach, features, and deployment process.
