Here's an idea.
A program that examines your SaaS/cloud use, downloads and adapts standalone products that you can use on your intranet instead of them, advises you as to on prem storage needs, and can then close your SaaS and cloud subscriptions after returning your data to local drives. It then blocks all access to the public internet from your intranet. Your system is now secure from online threats and free from SaaS, cloud and AI security issues.
A sure fire winner for increasing your security. That must be worth some VC.
