Of the tools that I've used, Sublime requires the least amount of ongoing day to day management or tweaking. It also has the lowest rate of false positives I've used in my career. The ROI on having Sublime is near immediate to show, and our employees immediately noticed a difference when it was integrated.
Having ADE's auto evaluation of specific emails has also been immensely helpful in providing more context to reduce the amount of toil a security team has in manually reviewing every user report. Review collected by and hosted on G2.com.
We haven’t run into many issues with false positives, and there aren’t a lot of edge cases that feel like they need major improvement. That said, some UI elements can be a bit hard to locate if you’re not using the tool every day. Review collected by and hosted on G2.com.
