What Our Customers are Saying

Jeff R.

Love the product, bought it on a whim with DisplayFusion and have been pleasantly surprised. I've used a lot of log tools over years.

@SwiftOnSecurity

Honestly the ability to live-filter events in a GUI with a syntax like
username7 -warning -code589 -debug
is so awesome and helps me fix problems really fast.
Yes there's other ways to do it I just like this one a lot.
