It seems to primarily operate on the endpoints rather than at a central location pushing out policies.

The solution is not scalable as it is an agent product rather than a product designed for scalability.
Owner at Darcom
 

Setup Cost

ThreatLocker offers a cost-effective Zero Trust solution with flexible pricing, appreciated for transparency and easy setup across clients.
Trend Micro Deep Discovery pricing varies with requirements, seen as reasonable for advanced features but higher than standard antivirus.
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.'
Supervisor, Client Security at a consultancy with 11-50 employees
I had a really good deal at the time, and it continues to be cost-effective.

Featured Reviews

CL
Supervisor, Client Security at a consultancy with 11-50 employees
World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.

Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.
