VNS3 in Practice - Architecting Secure Cloud Networks

About VNS3 Training

The VNS3 Certified Architect - Designing and Securing Cloud Networks course is intended for individuals who have experience with both VNS3 networking fundamentals and public cloud architectures. Users who can set up and connection IPsec connections and interpret network command line tools will benefit from this course.

The VNS3 Architect course applies VNS3 foundations to real-world scenarios. The course begins with how VNS3 can enhance AWS or Azure cloud networks, from routing to security. Building on the strong cloud and networking fundamentals from the VNS3 Associate course, this level will dive directly into using, customizing, and troubleshooting VNS3 networks in cloud.
