I like how easy it is for me as an IT admin/security person or even just someone who wants some extra eyes looking at their system logs etc - It's very simple but does what its supposed too! There are times when you have multiple applications running which can cause problems with logging so this helps out there also!! Nothing really bad about last line defender itself however if anything i wish we could get more alerts from them regarding suspicious activity / attacks happening towards our systems.
But overall good product great price friendly support team excellent customer service all around awesome tool definitely recommend using. Alerting us whenever something happens such as any log entry changes made by another user - Helps keep track of everything going on inside my server allowing quick response time should issues arise.
