We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
4.1
Symantec Endpoint Security's robust protection minimizes ransomware impact, ensuring data security and ROI for manufacturing firms against cyber threats.
Sentiment score
7.9
ThreatLocker Zero Trust Platform enhances security, improves efficiency, saves costs, increases revenue, and supports business growth by reducing threats.
If something were to happen without ThreatLocker, the cost would be huge, and thus, having it is definitely worth it.
The main return on investment is peace of mind, knowing that with ThreatLocker on any endpoint, it will almost always block all malicious code or exploits, even zero-day exploits.
It keeps malware, Trojans, and ransomware at bay.
 

Customer Service

Sentiment score
5.5
Symantec Endpoint Security's technical support is mixed, with responsive service overall but variations in speed and costlier advanced support.
Sentiment score
7.7
ThreatLocker Zero Trust's responsive customer service, highlighted by the Cyber Hero program, is praised for speed, professionalism, and effectiveness.
The support site for accessing new software is complicated, despite necessary multi-factor authentication.
I rate the technical support from Symantec as eight out of ten because they have comprehensive and clear documentation that can be easily found on search engines if someone knows how to search.
They have been very responsive, helpful, and knowledgeable.
I would rate their customer support a ten out of ten.
Their support is world-class.
 

Scalability Issues

Sentiment score
8.0
Symantec Endpoint Security Enterprise scales well for all business sizes, though costly and affected by network configuration challenges.
Sentiment score
8.0
ThreatLocker Zero Trust Platform offers seamless scalability and adaptability, efficiently managing diverse environments and dynamic growth across endpoints.
Regarding scalability, since Symantec Endpoint Security Enterprise is a cloud solution, it is very scalable.
In my experience supporting approximately 10 different companies with up to 100 workstations each, scalability has never been a concern with Symantec Endpoint Security Enterprise.
I started off with just the servers, and within a month and a half, I set up the entire company with ThreatLocker.
It seems to primarily operate on the endpoints rather than at a central location pushing out policies.
I would rate it a ten out of ten for scalability.
 

Stability Issues

Sentiment score
8.9
Symantec Endpoint Security Enterprise is praised for reliability but has occasional issues, mainly with Windows updates and scans.
Sentiment score
7.4
ThreatLocker Zero Trust Platform is praised for stability and reliability, with minor issues swiftly addressed by support.
I rate the stability of Symantec Endpoint Security Enterprise as excellent, giving it a nine for all the new possibilities and features that can be implemented.
The solution is exceptionally stable.
For five years, we have not had a problem.
Once deployed, it downloads the policies locally, so even if the computer doesn't have internet, it doesn't matter.
It has been very stable, reliable, and accessible.
 

Room For Improvement

Symantec Endpoint Security Enterprise needs user-friendliness upgrades, better Mac compatibility, and improved pricing, threat notifications, and support services.
ThreatLocker needs UI improvements, better integrations, expanded training, enhanced analytics, restricted Learning Mode, and faster support.
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.
Controlling the cloud environment, not just endpoints, is crucial.
This is problematic when immediate attention is needed.
Comprehensive 24-hour log monitoring is a valuable enhancement for both business and enterprise-level users.
 

Setup Cost

Symantec's pricing is seen as reasonable by some but expensive by others, particularly when upgrading to EDR.
Enterprise buyers find ThreatLocker's pricing competitive and flexible, valuing its affordability, transparency, and accessible setup costs.
After conversations with other partners, it became clear we underpriced it initially, which caused most of our issues.
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.
 

Valuable Features

Symantec Endpoint Security Enterprise offers proactive threat protection, ease of use, scalability, and cost-effective basic security with frequent updates.
ThreatLocker Zero Trust Platform enhances security with features like application control, selective elevation, and robust network access controls.
What I appreciate the most about Symantec Endpoint Security Enterprise is the integration with the workstations and the around-the-clock monitoring.
Symantec Endpoint Security Enterprise is highly compatible and rarely causes disruptions in production.
ThreatLocker Zero Trust Endpoint Protection Platform's ability to block access to unauthorized applications has been excellent.
It protects our customers.
The major benefit is fewer breaches overall, as nothing can be run without prior approval. This helps my company protect its data and secure itself effectively.

A product that offers good threat detection capabilities to its users
The product has improved my company through its area of threat detection. The other applications use the same engine as Symantec Endpoint Security Enterprise. Symantec Endpoint Security Enterprise does not have a set of 100 percent useful things in the tool. Sometimes, a user may know that a file system does not contain any viruses, but it is labeled as a virus by Symantec Endpoint Security Enterprise, making it an issue for users. The aforementioned problem prompts me to contact the product support team via email so that my company can get some help dealing with such problems. I would say that my experience with deploying the product across multiple devices in my company is not tough and can be easy, especially if you have domain environments. The feature of the product that is the most effective for threat prevention stems from the fact that the tool provides updates. The main problem with the solution is that a user has to do the updates manually, so at times, the product is not useful, especially when the machine has to be shut down for updates when new viruses are introduced on the market. I rate the solution's ease of use and administration a seven and a half out of ten. I suggest that those who plan to buy the solution periodically update the product, especially in the area of the virus engine. I rate the tool an eight out of ten.

Ensures ransomware protection and reduces phishing chaos
The application control has been great so far, and while I am still exploring the network access controls, I unfortunately don't have access to one module I would love to have due to licensing restrictions. It's easy to use in regard to reducing attack surfaces. For me, it's a piece of cake. We can have something approved within 30 seconds, thanks to the mobile app. We haven't eliminated security solutions. We just add to it, and ThreatLocker has been a great addition. We also have Kaseya and ThreatLocker as a supplement to that. It's useful. They have overlap, and we look at the overlap as a good thing. It's helped your organization save on operational costs or expenses by ensuring that many fewer hours are spent dealing with ransomware nonsense. I cannot count the amount of hours that I personally have not had to put in to recovering an environment from a ransomware event. The last big one took us about three weeks to completely recover from. Since we've grouped ThreatLocker in, the management of that whole setup has gone down to just daily help desk tasks and general server maintenance instead of having the whole system on fire. There are probably thousands of hours of saved time between our teams. It's been great so far. ThreatLocker Zero Trust Endpoint Protection Platform's ability to block access to unauthorized applications is great. It's my biggest protection, the blocked applications. In a lot of cases, you go to install something yourself that you need for management, and it comes in and says, nope. And then I have to log into the portal and approve it. I get our other guys saying, hey, why are you trying to approve something? Any of the tools that I'm using on a day-to-day basis that haven't been in the environment during the whole learning mode initially, I could go through and set extensions and all that. So, while it's a headache on that end, the amount of saved time I can't even count. It is a little frustrating on my end since I like to go as quickly as I possibly can, and it slows me down. However, that's a really good thing. Depending on the site, it can save a lot of time and cut down headaches. It's likely saved a week's worth of time. It's cut down the amount of sever help desk tickets. Those have become minimal.
