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.

After updating firmware, data utilization was visible for a few days before collapsing again.
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
8.2
Check Point Harmony SASE is scalable, cloud-based, and adaptable but faces some redundancy limitations compared to competitors.
Sentiment score
8.2
ThreatLocker Zero Trust Platform offers seamless scalability and adaptability, efficiently managing diverse environments and dynamic growth across endpoints.
The cloud-native model ensures we are not tied to any specific location or hardware, which has been a great game changer in terms of agility.
The scalability of Check Point Harmony SASE (formerly Perimeter 81) is good, and I can add more users and devices easily as my organization grows.
I would rate it nine out of ten for scalability.
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
Check Point Harmony SASE is stable with 99.9% uptime, despite rare glitches, earning high user reliability ratings.
Sentiment score
7.5
ThreatLocker Zero Trust Platform is praised for stability and reliability, with minor issues swiftly addressed by support.
Even the support team does not have a proper solution for this issue.
There are some lags and glitches with connectivity, so I would rate the stability as between seven or eight out of ten.
After the last improvement, I can say it is much more stable now.
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

Check Point Harmony SASE could improve with SD-WAN, alerts, better UI, analytics, integration, support, and documentation enhancements.
ThreatLocker needs UI improvements, better integrations, expanded training, enhanced analytics, restricted Learning Mode, and faster support.
An example of when the support cycle took longer than expected was when I had a ticket open for nearly six to seven months regarding a simple issue.
A local data center in Turkey would enhance the product, as currently, our Internet traffic goes to another country, which is problematic for us.
One area for improvement is integration with third-party identity providers.
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

Check Point Harmony SASE offers clear pricing and flexibility, ideal for large enterprises but costly for small businesses.
Enterprise buyers find ThreatLocker's pricing competitive and flexible, valuing its affordability, transparency, and accessible setup costs.
Cost efficiency is a consideration, as SASE products are not the cheapest security products.
It is a bit expensive.
My experience with pricing, setup cost, and licensing for Check Point Harmony SASE (formerly Perimeter 81) is that it is a rental service, but I find it satisfactory.
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

Check Point Harmony SASE enhances security with Zero Trust Access, Secure Gateway, and ThreatCloud intelligence, optimizing remote work management.
ThreatLocker Zero Trust Platform enhances security with features like application control, selective elevation, and robust network access controls.
The firewall management is the most valuable feature for me.
The Zero Trust Network Access (ZTNA) feature is a major highlight as it gives users seamless and secure access to internal resources without requiring a full-blown VPN, which improves both security and user experience.
The best key features of Harmony are stabilization, private access, and Internet access.
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

Nasseer Qureshi - PeerSpot reviewer
Delivers seamless and secure remote access while enhancing security posture
Check Point Harmony SASE (formerly Perimeter 81) offers strong features, but there are areas that could be improved. One area for improvement is integration with third-party identity providers. It works with standard SAML and SSO, but we would prefer deeper integrations with solutions such as Ping for more advanced identity-based policies. Additionally, a mobile-specific client or lightweight agent would be helpful for securing access from smartphones, especially in BYOD environments. We would appreciate more granular reporting and analytics, including better drill-down capabilities to investigate specific users or app activity. The logs are comprehensive, but filtering them can sometimes feel messy. The user interface on the management portal could be more intuitive, especially when managing multiple sites or remote offices. Some of the policy configuration steps are nested and could be streamlined.
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.
