Kumbesh Rajagopal - PeerSpot reviewer
Senior Security Delivery Analyst at Accenture
Management becomes easier with minimal complications, but improvement in support tools needed
Regarding areas of improvement for Symantec Endpoint Security, there are many changes, and the support portal tool is complicated compared to other tools. When trying to get service from Symantec, the process is complex. I'm not sure whether it's because of my project or something else. Though it is easy to manage, easy to get, easy to install, and works efficiently for managing policies, we faced a significant disadvantage. We wanted to add multiple hashes because of numerous new alerts coming, but we could only add them one by one, which is a considerable disadvantage in Symantec.

World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.
