ROI

Sentiment score
4.2
Symantec Endpoint Security Complete's ROI is rated highly by some, yet high costs make benefits assessment challenging for others.
Sentiment score
8.1
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.

ThreatLocker Zero Trust's responsive customer service, highlighted by the Cyber Hero program, is praised for speed, professionalism, and effectiveness.
I don't know the current situation with Broadcom, however, it was good when I was involved.
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

7.1
Symantec Endpoint Security Complete displays strong scalability, though opinions vary on license challenges and support in different environments.
Sentiment score
8.2
ThreatLocker Zero Trust Platform offers seamless scalability and adaptability, efficiently managing diverse environments and dynamic growth across endpoints.
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
8.6
Symantec Endpoint Security Complete is reliable and stable, though new releases may introduce bugs, earning high user satisfaction.
Sentiment score
7.5
ThreatLocker Zero Trust Platform is praised for stability and reliability, with minor issues swiftly addressed by support.
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 Complete requires enhancements in installation, interface, mobility, security features, support, scalability, pricing, and integration.
ThreatLocker needs UI improvements, better integrations, expanded training, enhanced analytics, restricted Learning Mode, and faster support.
They could improve the user interface.
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 Endpoint Security Complete pricing varies, seen as cost-effective by some but expensive due to features and complex renewals.
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 Complete delivers advanced protection and governance with features like threat hunting, sandboxing, and customizable performance.
ThreatLocker Zero Trust Platform enhances security with features like application control, selective elevation, and robust network access controls.
I have both the antivirus and EDR features constantly, allowing my team's customers to conduct detailed analyses of where attacks have occurred or if any malicious files are present, which devices or files have been targeted.
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.

Featured Reviews

Livin Sunil - PeerSpot reviewer
Provides comprehensive protection with a need for a more intuitive interface
Security Complete comes with antivirus plus EDR, which is a convergence of antivirus and EDR. I have both the antivirus and EDR features constantly, allowing my team's customers to conduct detailed analyses of where attacks have occurred or if any malicious files are present, which devices or files have been targeted. It provides a greater level of view, making it easy for my team to mitigate those particular attacks.
Johnathan Bodily - PeerSpot reviewer
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.
