Trend Micro Deep Discovery is scalable but may face limitations due to network design, integration costs, and organizational needs.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
IT Manager at Daltons Limited
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
Cewa Solutions Architect at a tech services company with 11-50 employees
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.

If the appliance supports scalability, Trend Micro support will inform us, and we can implement it without replacing the hardware.

Room For Improvement

These sessions should be around five to ten minutes long, allowing users and partners to quickly grasp the information without disrupting their daily tasks.

The solution should be able to implement machine learning and analytics of all the logs for threat detection and protection.

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.

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

Setup Cost

Enterprise buyers find Fortinet FortiGate costly initially, but cheaper overall, despite some high renewal and setup costs.
Trend Micro Deep Discovery pricing varies with requirements, seen as reasonable for advanced features but higher than standard antivirus.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.

It offers cost savings as it is generally cheaper than the competition.
IT Infrastructure Architect at Apotek 1
It is about 20% cheaper.
Network Security Engineer at TD SYNNEX
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.

Manager, Information Technology Operation/Presales at TechMonarch
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

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.

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
