Kaspersky EDR is far superior to other products. It gives detailed information about malware, geolocation, and more. Also, the agent itself is very lightweight compared to other products. The packages and updates were quite small in size, just a few KBs.
And the best part is that when you apply a policy or make any changes, it immediately works. Regardless of the device's location, as long as it's reachable to the server, the policy applies within fractions of seconds. I had hands-on experience with an on-premises server on my premises. Once I applied any policy or made changes, it was assessed immediately, even if the PC was in a different country. As long as my PC was reachable, everything worked fine.
Moreover, the reports Kaspersky EDR generates, like the weekly and monthly reports, were amazing. We fully customized the on-premises server according to our needs, including how to push Windows patches, application updates, and whitelisting. One of the things I really like about Kaspersky is that even as an administrator, it won't allow you to bypass the applied policies.
The main issue was compatibility with the cloud itself. The CPU usage immediately spiked, causing the machines to hang and sometimes even forcing server or computer restarts. Within seconds of installing the agent, the CPU usage would become extremely high, rendering the machine practically unusable until we either manually restarted it or initiated a forced restart. We were left with no option but to uninstall the client.
It was the primary issue. When the agent was installed from the cloud portal, the machine became completely unresponsive and disconnected from the network.
I was quite satisfied with Kaspersky products when they were on-premises. The server was downloading the updates and signatures smoothly, and it was fully stable in our network. However, we decided to move to the cloud as we were offered better options, and there was no significant pricing difference. But unfortunately, once we moved to the cloud and deployed the agents on our clients, our clients started facing disconnection issues. We had no choice but to forcefully restart the machines. We tried seeking help from Kaspersky, but we didn't receive any assistance, which led us to switch to another product.
