Secure Score Actions and security guide

Yes, if you go to the Score Analyzer tab, there is an Export option and CSV - Action List option.

Also Taen keren, not sure about external but here are the https://support.office.com/en-us/article/Security-best-practices-for-Office-365-9295e396-e53d-49b9-ae9b-0b5828cdedc3, though some of these options are only available with Office 365 E5 licences.  There is also much more information here - https://support.office.com/en-us/article/Overview-of-security-and-compliance-in-Office-365-DCB83B2C-AC66-4CED-925D-50EB9698A0B2 that are well worth checking out.  I particularly like the Information Protection for Office 365 https://download.microsoft.com/download/2/3/D/23D91386-8349-4F7A-9470-FD5AED861F16/MSFT_cloud_architecture_informationprotection.pdf. Finally, the https://support.office.com/en-us/article/Manage-external-sharing-for-your-SharePoint-Online-environment-C8A462EB-0723-4B0B-8D0A-70FEAFE4BE85 article might be of interest!
