Looking for a comparison of DLP enterprise solutions and best practices on deployment and integration

Hi peers,

Where can I find comparison/vendor evaluation regarding the following items:

1. An easy-to-deploy DLP solution that could be integrated with existing solutions such as SIEM, SWG, Firewalls and AD/AD-less environment. 
2. Best practices on deploying and integration such a solution?

Comparison specification:

• API capabilities
• customization 
• fingerprinting 
• data classification 
• encrypted data features covering data in motion, rest 
• useful features. 

Can anyone assist and share some details with me here? 

I highly appreciate the help. 

Regards.
