Featured Reviews

Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.
WilsonAitan - PeerSpot reviewer
Offers a single dashboard with customizable features and a cost-effective pricing structure
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features. Additionally, it has a cost-effective structure because it is based on data storage and the number of scans, rather than uploading data. This cost model impacts the customers positively by offering a more straightforward pricing structure.
