Firewalla Device: Debian Linux running on ARM processor with 4 cores. Code inside is a mix of Node / Python / C / Bash. The same stack runs on the Raspberry Pi. Development environment also runs on Intel-based processors and inside Docker containers. With the right magic, the code can run on any Linux platform, physical or virtual.
Firewalla App: native Objective-C mixed with Swift ... mainly Objective-C, we don't like Swift at the moment, it keeps on changing. Android is java, and java is boring.
Firewalla Cloud: Amazon EC2 (and related services). Everything runs as a microservice. Communications and security intelligence are in their own clusters. DynamoDB, Redis, route53, ALB, Dockers, EC2 ...
What is the firewall technology built on (above the OS)?
