"Feature-Rich Platform with Responsive Support, but Bugs Still Get in the Way"
3.5/5
What do you like best about Arbor Sightline?

That it has so many features including ones we never use. I also appreciate Arbor support and their usually quick response when we find a bug or problem. Ed and Eric Lomax have been particularly responsive. Review collected by and hosted on G2.com.

What do you dislike about Arbor Sightline?

The bugs. For example the Arsonist process has ground our DDoS protection to a halt and the bugs we find tend to crop up again. I found a bug in the REST API that was only recently fixed. We usually don't find these problems until they become a major issue. Review collected by and hosted on G2.com.

"Robust and Well-Supported, but UI Bugs and CLI Parity Gaps Hold It Back"
3/5
What do you like best about Arbor Sightline?

Seems to be pretty robust. Good support. Review collected by and hosted on G2.com.

What do you dislike about Arbor Sightline?

There isn't parity between the UI and the command line. Various UI bugs, particularly with keyboard input. Graphical charts don't always seem to match the data.

In Insight, copying results adds a facet. That is very annoying. Review collected by and hosted on G2.com.
