Pros
None compared to its peers
Cons
If you're a software developer you will spend most of your time requesting IT approval for individual packages, version by version, instead of writing code. If you use dockerhub you'll end up downloading externally and transferring images over to build containers. It takes too long to get approval through IT (and it's only for a single version). If there's a binary download as part of your CI/CD, you'll have to approve every version update to it (and occassionally it will break as they change policies with no communication). If you're a react web developer, you'll have to hack in react dev tools since the plugin is banned. Streaming music is banned. Need a rust crate? You get the picture, the list goes on and on. Their security solution is a man-in-the-middle attack that peeks at all your data, including personally identifiable information, and has a web whitelist like a high school computer lab. Do you prefer WSL? Too bad, it won't work reliably with the MitM attack. In the end, HII is a ship builder that recently decided to seek the margins of software development without actually understanding the domain, or building the infrastructure and expertise to support it.
