Hello @rebecca_robinso ...
Full disclosure... I'm not familiar with Proctorio, and I don't really know what it does...but I do see that it has an external app LTI integration with Canvas. My guess is that your school's local Canvas administrator or someone from your school's Online Learning/eLearning department would need to be involved in this conversation to see if purchasing this product is an option for you and your colleagues.
I hope this information will be of help to you, Rebecca. Sing out if you have any other questions about this. Take care...be well...stay safe.
