ROI

Sentiment score
4.4
OpenVPN Access Server boosts security, reduces costs, and enhances efficiency with SAML integration and faster key generation.
Sentiment score
6.2
ThreatLocker enhances security, reduces costs, boosts productivity, and facilitates growth by blocking unauthorized applications and preventing malware.
Now, with the SAML and Active Directory integration, the process is down to under two minutes, which frees up our senior staff to focus on critical infrastructure tasks instead of managing access tickets.

The platform automatically reads the user role and maps them to the correct network subnets instantly, saving us countless hours of administration overhead every month.

Financially, we observe that while costs were initially high, optimizing user connections has rendered better financial management in the long run, improving user access without extensive management needs.
Manager, Ott Platform at Synamedia
If something were to happen without ThreatLocker, the cost would be huge, and thus, having it is definitely worth it.
Tier 1 IT Engineer at a retailer with 11-50 employees
Based on what we use ThreatLocker Zero Trust Endpoint Protection Platform for with the same functionalities and packaging, it was around 13 or 14 hours.
Head Of Cyber Security at a outsourcing company with 201-500 employees
We have the MDR package as well, and just knowing someone is watching those endpoints at 3:00 a.m. is a lifesaver that you cannot put a dollar figure on.

Room For Improvement

OpenVPN Access Server needs enhanced usability, security, platform compatibility, and advanced features like AI, WireGuard, and identity integration.
Users seek improved training, integrations, transparency, UI, and communication in ThreatLocker Zero Trust Platform for enhanced usability and administration.
Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.

Additionally, native support for newer, lighter protocols like WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency would be beneficial.
Manager at a computer software company with 201-500 employees
With WireGuard, which is locked down over UDP, it is harder for attackers to probe ports.
代表社員 at サザビー
Controlling the cloud environment, not just endpoints, is crucial.
COO at Panda Technology
ThreatLocker Zero Trust Endpoint Protection Platform could improve by being a little more hands-off, perhaps by having a team inside ThreatLocker that does all the vetting of patches; having one person hired by ThreatLocker to check out patches means that a million other industries using ThreatLocker Zero Trust Endpoint Protection Platform do not have to vet the same patch, ultimately saving time and money around the world.
Technical Support Engineer at CMIT Solutions of Central Orlando
This feedback would help us understand what is learned in real-time, especially during a one-hour learning mode setup, ensuring we remain aware of potentially unnecessary learned items.

Setup Cost

OpenVPN Access Server provides flexible pricing with a free tier for individuals and affordable enterprise options with minimal setup costs.
ThreatLocker Zero Trust Platform provides flexible, scalable pricing with tiered plans and negotiable deals, ensuring cost-effectiveness and transparency.
The sticker price may look clear, but the real cost includes the time spent untangling subscription limitations, account conflicts, sales handoffs, and unclear guidance.
Webmaster & Software Engineer at a university with 501-1,000 employees
My experience with pricing is excellent as the pricing is free.
Service Delivery Manager at CasCom
The experience with pricing, setup cost, and licensing for OpenVPN Access Server is really good, not that expensive.
Devops Engineer at Emergent
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.'
Supervisor, Client Security at a consultancy with 11-50 employees
Money is saved because it is not costly, and I would suggest it for other companies.

Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.
Santo Joy - PeerSpot reviewer
Head Of Cyber Security at a outsourcing company with 201-500 employees
Security controls have been strengthened with granular application, ringfencing, and access policies
The features of ThreatLocker Zero Trust Endpoint Protection Platform that I like the most are the Ringfencing, elevation control, storage control, and application whitelisting functionality. For examples of how these features benefit my company, we were looking for a solution across various vendors to actually implement application whitelisting controls. ThreatLocker's agent, which is very lightweight and does not use much CPU or RAM, helped us achieve that solution. Ringfencing was an add-on that ticked off a lot of Australian framework security controls, which is the reason we chose it. My impression of the allowlisting feature in terms of managing which software, scripts, and libraries run on my devices is that ThreatLocker's community page has a lot of information around this, which is very helpful. Not only that, the Cyber Hero support that ThreatLocker provides gives us insights and best practices, helping us achieve that solution and guiding us to the right platform. The impact of Ringfencing on controlling the behavior of approved applications has been a big winner for us because it is something that many other platforms do not provide as a functionality. Having that allowed us to identify what applications talk to each other, which is something that many other platforms do not do. The network control feature impacts my ability to manage network traffic across my endpoints and servers. We have not used this widely across all our partners, but wherever required, we use it. It has been an easy solution for those customers to get that control implemented. The elevation feature's role in facilitating just-in-time administrative access for approved applications shows that elevation control helps in many use cases involving remote control platforms, door usage, and security system platforms that require local admins. There are many solutions that provide this functionality, but the licensing cost seems to be expensive, and it also adds another solution into the mix. Rather than doing that, we try to use ThreatLocker Zero Trust Endpoint Protection Platform to achieve that control. Regarding the storage control feature, I have used it. The primary function is USB blocking, which is very widely adopted, and also just locking down and allowing certain users to access certain file locations helps us there. When it comes to enforcing policy-driven access over various storage devices, it depends on the business risk adapted by the companies that we support, but generally the use case is USB and external storage devices where companies know that is a risk, but they do not have appropriate solutions. There are EDR platforms that claim to do this, but ThreatLocker Zero Trust Endpoint Protection Platform does it at an advanced level. My assessment of the efficiency of the real-time threat intelligence and category controls employed by Web Control in blocking malicious and non-compliant sites leads me to think that Web Control is another functionality within ThreatLocker Zero Trust Endpoint Protection Platform that is an add-on on top of the current set. That is another solution that we use based on what is required for the company, but again, that is not widely adapted yet for our partners.
