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

ROI

Sentiment score
5.9
ThreatLocker Zero Trust Platform reduces security incidents, lowers costs, and increases efficiency with enhanced control and real-time protection.
Sentiment score
6.1
Trend Micro Deep Discovery offers mixed financial results but increases security with threat visibility, sandbox, and IDS enhancements.
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.

Sentiment score
7.5
Trend Micro Deep Discovery [EOL] provides scalable cloud management, effectively serving enterprises, government, and financial sectors, despite network limitations.
I started off with just the servers, and within a month and a half, I set up the entire company with ThreatLocker.
Technical Engineer at Cloud 1 Solutions
It seems to primarily operate on the endpoints rather than at a central location pushing out policies.
Systems Security Analyst & Deputy Security Officer at a financial services firm with 201-500 employees
ThreatLocker Zero Trust Endpoint Protection Platform scales very smoothly with our growing needs.
CEO at Mostro
If the appliance supports scalability, Trend Micro support will inform us, and we can implement it without replacing the hardware.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
 

Stability Issues

Sentiment score
8.0
ThreatLocker Zero Trust Platform is reliable, with minimal issues, quick support, and high satisfaction despite rare glitches.
Sentiment score
8.3
Trend Micro Deep Discovery is stable and reliable, scoring high in user ratings with consistent performance and valuable support.
For five years, we have not had a problem.
Supervisor, Client Security at a consultancy with 11-50 employees
Once deployed, it downloads the policies locally, so even if the computer doesn't have internet, it doesn't matter.
Information Cybersecurity Technology Specialist at Freez.it
It has been very stable, reliable, and accessible.
COO at Panda Technology
The product updates and security updates are kept current, allowing us seamless integration with Trend Micro and getting daily updates and signatures without problems.

Room For Improvement

The ThreatLocker Zero Trust Platform needs flexible training, automated policies, better integrations, enhanced UI, and improved mobile management.
Trend Micro Deep Discovery faces challenges with integration, scalability, support, pricing, and requires improvements in usability and network capabilities.
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
We have multiple components such as Deep Discovery Email Inspector for mail gateways, Deep Discovery Analyzer for sandboxing, and Deep Discovery Inspector, which serves as an IDS detecting malicious network traffic.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
The solution is not scalable as it is an agent product rather than a product designed for scalability.
Owner at Darcom
There is no dedicated team in India for giving support for Trend Micro Deep Discovery.
Director at Business Automation Indore Private Limited
 

Setup Cost

ThreatLocker Zero Trust Platform offers competitive pricing with flexible tiers, direct quotes, and favorable features for enterprises.
Trend Micro Deep Discovery [EOL] pricing is annual, node-based, varies by requirements, and opinions differ on its competitiveness.
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
I do not consider it an expensive tool; its price is justified based on the capabilities that we receive when compared to another mail gateway or other vendors.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
The solution is very expensive.
Owner at Darcom
Overall, the licensing cost of Trend Micro Deep Discovery was not on the higher side earlier, but now, since the competition has increased, we need to think about the prices.
Director at Business Automation Indore Private Limited

Featured Reviews

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.

Long-term threat visibility has reduced customer incidents and supports steady recurring revenue
The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied. My customers have indeed utilized the Threat Intelligence Sharing feature of Trend Micro Deep Discovery. The impact of the Threat Intelligence Sharing feature on overall defense and security is positive. The benefit that Deep Discovery brings to our organization is that we get fewer calls from customers, allowing me to focus on other businesses, and we receive year-on-year revenue for renewals.
