Is Renaissance LockDown Browser safe?

Clean risk

Renaissance LockDown Browser transmits exam session PII to Respondus servers and disables other browser extensions during active exams.

During an exam session, the extension sends the student's username, first name, last name, exam ID, and question timing data to smc-service-cloud.respondus2.com. It also calls chrome.management.setEnabled to disable all browser extensions not on an exam allowlist, forcibly re-disabling any that attempt to re-enable themselves. When an exam ends, previously disabled extensions are restored.

Where it sends data

Destinations our analysis observed Renaissance LockDown Browser contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • smc-service-cloud.respondus2.com

    Renaissance LockDown Browser sends data to smc-service-cloud.respondus2.com. One other extension we have analysed sends data here.
