Angelfish is installed in your network, which means you have full access control and complete data privacy. This is especially critical for organizations in regulated industries (e.g. healthcare, finance, government / military) and will affect all organizations as data privacy laws continue to expand.
Data privacy isn't really possible with a SaaS-based application - when data lives outside your network, you never know who can access it.
Angelfish is designed to be interoperable with 3rd party applications - data can be exported into a third party application or database via an API request. However, no data is exported unless you explicitly allow it to be exported.
