BPS Pro Security Logs are automatically zipped and emailed (when they reach the max file size setting) to whatever email addresses have been added on the BPS Pro > Display & Alert Options page. At the top of each Security Log file there is a summary of logged events in each Security Log file.
If you are only looking for people who logged into a website you can download the Login Security database table by clicking the Export|Download Login Security Table button on the Login Security page.
I intentionally did not waste database resources by using the WP database to store Security Log entries since the WP DB would grow exponentially.
