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

ROI

Sentiment score
4.4
Portnox's cloud NAC boosts ROI by reducing infrastructure costs, automating processes, and enhancing security with improved device control.
Sentiment score
6.2
ThreatLocker enhances security, reduces costs, boosts productivity, and facilitates growth by blocking unauthorized applications and preventing malware.
If I compare this to an on-premises environment using Cisco ISE or Aruba ClearPass, it would require phenomenally large teams for infrastructure management.
Principle Cloud Architect at a tech services company with 11-50 employees
If you were moving from a traditional on-premise NAC that was 100% managed by the IT department, there would be great savings in going to a cloud-based NAC with Portnox.
IT Infrastructure Manager at a tech vendor with 501-1,000 employees
By automating the device containment and remediation processes, we save countless hours weekly.
Network operation center engineer at a computer software company with 10,001+ employees
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

Users suggest load distribution, improved vendor integration, better reporting, UI updates, and increased support for enhanced system performance.
Users seek improved training, integrations, transparency, UI, and communication in ThreatLocker Zero Trust Platform for enhanced usability and administration.
Ideally, we should be able to search for any MAC address in the database, regardless of its authentication status, to see all its associated groups and potential conflicts.
President at TrackerSoft
When I reach the technical support, they give solutions that do not help me much, so I try to search the internet for other users' experiences to find solutions.
IT Project Manager at Xpress technologies
I would definitely request a UI refresh that makes the dashboard more modern and surfaces critical logs so they are easier to access in a pinch.
Manager at a computer software company with 201-500 employees
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

Portnox offers flexible, competitive pricing based on switch ports, with cloud-native licensing attractive for enterprises seeking simplified budgeting.
ThreatLocker Zero Trust Platform provides flexible, scalable pricing with tiered plans and negotiable deals, ensuring cost-effectiveness and transparency.
If you compare Portnox with all other well-known standard products, it is the cheapest.
IT Network Engineer at a tech vendor with 5,001-10,000 employees
The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe.
President at TrackerSoft
You are charged according to the number of users.
Senior Network Engineer at a tech services company with 11-50 employees
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.

Valuable Features

Portnox offers cloud-native architecture for network visibility, automated access control, scalability, and enhanced security through various features.
ThreatLocker Zero Trust Platform excels in app control, security features, and support, enhancing IT efficiency and company security.
It's notable how Portnox has improved operational efficiency.

Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees
It is possible to find the MAC address in the switch, but in Portnox, it is very useful to see the status of those ports, and that increases our security.
Assistant System Engineer at Tata Consultancy
ThreatLocker Zero Trust Endpoint Protection Platform's ability to block access to unauthorized applications has been excellent.
Cyber Security Specialist at Bremmar Consulting
It protects our customers.
CTO at Zettabytes

Featured Reviews

Maurice Mwaura - PeerSpot reviewer
Product Manager at Applied Principles Limited
Unified access control has improved compliance visibility and simplified passwordless access
There is work to be done when it comes to making the solution more seamless. For example, when a user is denied access, they would need a way to maybe self-resolve themselves, perhaps a way to generate a ticket on their own, something around resolutions. When it comes to users using the product, that is where good products are differentiated from products that are a bit of a challenge. Portnox has much to do in terms of their reporting. The generated reports need improvement. Things that other tools would say are normal are usually not present. For example, there is a page called NAS devices or NAS network that is able to show the switches that have been managed. Currently, there is no way of generating an easy report or an easy way of just generating something to tell the customer what they have been able to achieve so far. This is not done yet and is still very manual. I think there is work to be done there. More integrations around the various products being used would be beneficial. So far I have not encountered any major challenge. Where there was a challenge, I think support came in and helped us resolve. In fact, most of the challenges are not with the product; they are with the customer environment. I think that is just to update their documentation where they have come across a new vendor for easier integrations in the future.
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.
