Customer Reviews

Works Great … missing the GEO IP Tool interface - presentation ?

Works Great, would give it 5 stars if it had the Geo IP address built-in as the presentation suggests.
- Caught a hacker in the first 30 seconds of using it, wish I didn’t have to waste time manually looking up the IP address though.
- Great added feature would be to be able to terminate a network link/call/response based on Source or Destination IP Address, possibly based on Port in the future also.

Crashes at open

Opened the app, and it crashes on me every time. I deleted the app and redownloaded it, but it still crashes.
