Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The ability to detect activity on the network is very useful to us. Even if it's not necessarily an illegal activity, if it is abnormal activity, it is able to detect it and notify us."
"The product is extremely stable and mature."
"We allow customers to access our Wi-Fi as guests, and some of them were going to restricted sites. Darktrace showed us what they were doing so we could block them."
"Darktrace has improved our knowledge of abnormal phenomenen which could have potentially be hazardous for the organization."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"The scalability of Darktrace is very high."
"Darktrace has helped our organization be secure from network spam and attacks."

Cons

"The pricing is a bit high for the region."
"The program is quite expensive."

"The main portal needs improvement as it is difficult to use."
"Darktrace requires numerous configurations. It would be beneficial if the configuration could be made simpler."
