Thank you for clarifying .
I've come across a couple companies doing that. I've never seen the point. You can get the forensic tools yourself for cheaper. I'm assuming the bundling company facilitates interoperability, but that insnt worth the extra cost.
I can't speak for your morals or how you value privacy. I think the deciding factor may be who the customers are. Law enforcement is where your work can do the most good - people will be safer because of your work. Some future victims will even be alive because of it. But you may not agree with the legal standards they have to abide by. That is the best case, it would be foolish to think those rules are always followed. And you may not think the legal remedies are sufficient.
ediscovery is a bit different. I'd wager most of your customers will be corporations, processing corporate data. They're will definitely be personal data, but an employee putting sensitive personal data (that the company doesn't already have) is kind of giving up their expectation to privacy. Your other customer might be law firms or ediscovery firms, but their clients would be initiating or party to the lawsuit. They would be provided a chance to argue what is discoverable. Sensitive data unrelated to the lawsuit would remain private.
Hope this helps or at least gives you something to think about.
