ROI

Sentiment score
6.9
Fortinet FortiClient boosted productivity and security, reduced VPN costs by 8%, but faced challenges in functionality activation.
Sentiment score
8.1
ThreatLocker Zero Trust Platform enhances security, improves efficiency, saves costs, increases revenue, and supports business growth by reducing threats.
The VPN performance has a substantial impact on our remote workforce.
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
6.5
Fortinet FortiClient's customer service varies, with response times and resolution quality improving notably for higher-tier service subscribers.
Sentiment score
7.6
ThreatLocker Zero Trust's responsive customer service, highlighted by the Cyber Hero program, is praised for speed, professionalism, and effectiveness.
They initiate the troubleshooting process quickly and resolve issues in a timely manner.
They provide very good support, and an issue I had was resolved quickly over the phone.
Technical support can be logged on Fortinet's support portal.
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
7.3
Fortinet FortiClient is praised for scalability, easily accommodating user expansion and seamless integration, despite some suggested improvements.
Sentiment score
8.2
ThreatLocker Zero Trust Platform offers seamless scalability and adaptability, efficiently managing diverse environments and dynamic growth across endpoints.
I hope Fortinet will start an insider developer program where professionals can provide feedback on new releases to ensure improvements.
We can add more licenses and Fortinet tokens, demonstrating excellent scalability.
We can recommend FortiClient for small organizations with 50 to 60 users as well as for larger enterprises due to its extensive features.
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
7.8
Fortinet FortiClient is praised for its stability, reliability, and performance, with minor issues quickly resolved through updates.
Sentiment score
7.5
ThreatLocker Zero Trust Platform is praised for stability and reliability, with minor issues swiftly addressed by support.
Its stability level is excellent.
The overall stability of Fortinet FortiClient rates at nine out of ten.
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

Fortinet FortiClient requires improvements in management, configuration, compatibility, user interface, and integration with additional security features and platforms.
ThreatLocker needs UI improvements, better integrations, expanded training, enhanced analytics, restricted Learning Mode, and faster support.
FortiClient needs improvement in restricting user information and ensuring more secure customer data to better protect source code and reduce the risk of security breaches.
There are advanced features like Zero Trust that I currently do not use but could be beneficial for security.
Fortinet frequently releases updates without thorough testing.
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

Fortinet FortiClient offers cost-effective VPN solutions with variable pricing, requiring licenses for advanced features, often rated reasonably by users.
Enterprise buyers find ThreatLocker's pricing competitive and flexible, valuing its affordability, transparency, and accessible setup costs.
FortiClient is a value-for-money product and is not considered expensive compared to similar products on the market.
Justifying the price to clients can be difficult.
FortiClient is included in a package with the UTM features, so there is no separate cost for it.
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

Fortinet FortiClient provides strong security features, easy management, and integration, enhancing VPN services and endpoint protection.
ThreatLocker Zero Trust Platform enhances security with features like application control, selective elevation, and robust network access controls.
The most valuable feature of FortiClient is its high security level.
We appreciate its VPN capabilities and the features that offer extra security functionalities like antivirus and malware scanning.
I strongly recommend this solution, especially for Fortinet customers who use FortiGate or other Fortinet products, as they can easily integrate these features and exchange information seamlessly.
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.

Users only need to install the VPN and authenticate with their email address
I primarily use remote VPN solutions to connect securely. We have configured both site-to-site VPN and remote VPN, and it is connected to FortiClient Implementing this solution has streamlined time management in our organization. Without SSO, we would need manual configuration for each PC, but…
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.
