Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.
Simon Johnston - PeerSpot reviewer
Manager, Customer Success at Coltek Business Soltuions
Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.
