MS
Owner at Online IT
Cloud-based protection has simplified daily client support and keeps threats under control
The problems that we are facing with policy adoption include slow adoption, as it takes more than five minutes to adopt policy on client computers. ESET Network Attack Protection sometimes helps in reducing network-level intrusions, but sometimes it prevents local devices on the network, which are well-known and good devices, from being recognized, treating them as a threat. So it requires more administration than usual. ESET could implement a good solution for remote support in ESET Endpoint Protection Platform for improvement in the future. Since you have the cloud console, ESET could have something similar to AnyDesk or TeamViewer, but from ESET.
Emeka Ndulu - PeerSpot reviewer
Cloud Solutions Architect at a tech services company with 201-500 employees
Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.
