ROI

Sentiment score
3.8
NodeZero Platform reduces pen testing costs and time while enhancing security, saving up to 20% and improving efficiency.
Sentiment score
6.2
ThreatLocker enhances security, reduces costs, boosts productivity, and facilitates growth by blocking unauthorized applications and preventing malware.
A reduction in remediation time has been seen because it is finding things before they happen.
Director of Enterprise Security at a energy/utilities company with 51-200 employees
Being able to find them because there have been no eyes on that particular section so far ever, and fixing those potentially prevented those companies from getting breached.
IT Security Consultant at Systemhaus for you GmbH
So far, I have seen a return on investment with The NodeZero Platform by Horizon3.ai, as we managed to save a lot of time and effort with this because this is an autonomous tool, and our manual effort is significantly reduced because of a product of this type.
Senior Manager | Manager Security Services at RISK ASSOCIATES
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 want better flexibility, integration, scalability, testing efficiency, visibility, and reporting in vulnerability management and notification systems.

This service reveals which credentials and email addresses are available on the deep web, as well as which domains have been set up using typo-squatting techniques.
Information Security Manager at a non-profit with 51-200 employees
The one thing that is very much asked from us as a service provider is DAST testing, so when a company is building a software, they could see their current security status while they are building the application.
Offensive Security Analyst at a tech services company with 201-500 employees
If that pen test could be load balanced on more than one system, I believe The NodeZero Platform by Horizon3.ai could leverage that system and complete penetration tests in a much quicker time frame, providing quicker results to customers.
Lead Security Engineer at a healthcare company with 10,001+ 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.
Server Administrator at Clay County Sheriff's Office
 

Setup Cost

Enterprise users appreciate Horizon3.ai's competitive pricing and flexible IP-based licensing as cost-efficient compared to traditional methods.
ThreatLocker Zero Trust Platform provides flexible, scalable pricing with tiered plans and negotiable deals, ensuring cost-effectiveness and transparency.
The pricing is much more affordable than traditional penetration tests.
Manager, Information Technology at a performing arts with 11-50 employees
It's a bit cheaper than manual penetration testing because manual testing typically allows you to scan only a few subnets.
Works at a hospitality company with 201-500 employees
Usually, manual penetration test scans take considerable time and money.
Security Engineer at Herjavec Group
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.
Helpdesk Engineer at Computer Network Infrastructure (CNI) Consultants

Featured Reviews

Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.
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.
