Room For Improvement

Symantec Endpoint Security Enterprise needs user-friendliness upgrades, better Mac compatibility, and improved pricing, threat notifications, and support services.

Many customers are seeking modern protection features such as MDR (managed detection and response).

The centralized management console is intuitive, but the threat intelligence aspect could be more incorporated and developed, especially with AI integration and news directly in the platform.

After conversations with other partners, it became clear we underpriced it initially, which caused most of our issues.
Director, Managed Services at a consultancy with 11-50 employees
We are moving towards the Unified solution, where they basically bundle everything together, providing us better stability with the ability to bring in new product offerings without having to go back to the customer and say, 'This is going to cost you.'

I had a really good deal at the time, and it continues to be cost-effective.

Provides stable and resource-efficient protection but lacks clear modern security features
Symantec Endpoint Security Enterprise is highly compatible and rarely causes disruptions in production. It operates transparently and is easy to maintain. The automated response feature helps to mitigate breaches effectively. When comparing with ThreatDown agent, I have noticed that ThreatDown detects behaviors more readily and flags suspicious user activities more clearly. While Symantec Endpoint Security Enterprise remains effective, ThreatDown's user interface is more manageable and provides a clearer system overview. The management interface is crucial for maintaining Symantec Endpoint Security Enterprise effectively. A significant advantage of Symantec Endpoint Security Enterprise is its lightweight resource usage. It consumes less memory, CPU, and IO compared to alternatives such as ThreatDown and Bitdefender.

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.
