I wrote to Trusteer, because the "safe" icon that is to appear in the Address Bar is missing in El Capitán.
IBM's reply (in part):
"Please be informed that Trusteer Endpoint Protection is not yet compatible with Mac OS X 10.11 ("El Capitan") and Microsoft Edge web browser.
f you're using one of the platforms above, Rapport's icon will not be visible next to your address bar and your online activity will not be protected by Rapport."
Of course, no ETA was made re date fix/new version release.
