Trend Micro™ Deep Security™ software provides comprehensive security for virtual, cloud, and container environments. Deep Security allows for consistent security regardless of the workload. It also provides a rich set of application programming interfaces (APIs) so security can be automated.
Prior to using Sentinel, we were using Splunk specifically Splunk Enterprise Security and Splunk Cloud, so their on-prem and their cloud-based products. We switched originally for cost reasons, specifically cost control, but I have found that the ability to create reports, the …
Microsoft Sentinel feels on another different level from these solutions , all in the cloud . No need for troubleshooting , deployment or upgrades. Constant updates from the vendor and good support
Microsoft Sentinel excels in cloud-native scalability, Microsoft ecosystem integration, and AI-driven threat detection with UEBA and Fusion rules, offering faster deployment and lower costs (48% cheaper per Forrester) than Splunk, QRadar, Exabeam, SentinelOne, Securonix, and …
Well before there was Microsoft Sentinel, you had other competing products like ArcSight or Splunk, et cetera. I think they have their own qualities, but the Microsoft integration story is really why we're using it.
As mentioned, the product was part of the purchase of several Microsoft Suites that we did earlier last year and with 200 licenses included, we can exclude those from the other SIEM and SOAR product, it just work well with the Microsoft's environment that we partially have Is …
Microsoft Sentinel really goes the extra mile when it comes to an SIEM that slowly improves toward a proper SOAR, this may be the best selling point of the entire solution. Highly scalable, cloud-based, and nearly perfect when dealing with Microsoft-based infrastructures, …
As the vast majority of our users have Windows machine and uses all 365 cloud features, we finally decided not to implement any 3rd party security solutions on desktops/laptops in order to keep our infrastructure simple. In this case, Microsoft Sentinel is the best way to …
While both are market-leading SIEM platforms, they cater to different environments and organization priorities. The choice often comes down to a company's existing infrastructure, integration needs, and long-term security strategy. Deployment and architecture - Splunk offeres …
Splunk is proving to be a formidable replacement for Qradar, which we had as our previous SIEM. Qradar was powerful, but not easy to customize and quite limited. Splunk is not per se a "SIEM" but it can be in the way you used it. Also there is an Enterprise Security App that is …
Specifically for Microsoft Sentinel, it's going to have what's next to no value if you're not on Azure. You have to be in as your customer. If you want greater insight into what is going on in your cloud environment, turn Microsoft Sentinel on, but focus on where you enable it. You're not going to turn it on to see everything because it's not like focus on the areas where you are at risk or you believe you're at risk or something that you're, depending on your environment, do you have multiple subscriptions? Do you have a Microsoft Sentinel subscription that you just turned on, but it's not getting the visibility, and then you can alert on stuff that goes out of trend, etc.?
It's well suited for what I do, which is network security operations. And that's for anything from troubleshooting incidents, troubleshooting performance, troubleshooting for the purpose of a compliance and auditing. It's not best suited for users who are new in terms of they're new to the product and they have expectations that probably Splunk cannot meet.
Hypervisor based agentless security this product excels at. It provides thorough protection for your VM's. The web filtering product that comes with it also does a great job filtering out malicious websites from being accessed by users with a very user friendly prompt that they are going to a website which has been found to be malicious. This is particularly useful when it comes to VDI.
Strong integration with the Microsoft security ecosystem allows seamless connection to services such as Microsoft Defender, Microsoft 365, and Azure. This makes it easy to bring together identity, endpoint, and cloud signals to support investigation and detection scenarios.
Effective correlation of alerts and incidents in collaboration with Microsoft Defender XDR helps combine related signals into higher‑fidelity incidents. This reduces noise and improves visibility into attack context, making investigations more efficient.
High scalability for data ingestion and processing enables large volumes of security telemetry to be handled efficiently.
I think it's primarily going to be cost, since Microsoft Sentinel uses Microsoft Log Analytics as its base, right? So storing the logs and log retention is very expensive. That might result in users not adopting it as quickly. Second, I think Copilot for security can just do summarization and not many remediation tasks. In the future, we would like to see Copilot create many playbooks, including all box playbooks, to remediate many security issues.
Trend Micro has very little room for improvement. I am using version 9.6 at this time and it is extremely reliable. Some of the upgrades were not completely intuitive, but in those cases Deep Security support came through with documentation that covered all the bases.
We are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.
The Microsoft Azure Sentinel solution is very good and even better if you use Azure. It's easy to implement and learn how to use the tool with an intuitive and simple interface. New updates are happening to always bring new news and improve the experience and usability. The solution brings reliability as it is from a very reliable manufacturer.
You can literally throw in a single word into Splunk and it will pull back all instances of that word across all of your logs for the time span you select (provided you have permission to see that data). We have several users who have taken a few of the free courses from Splunk that are able to pull data out of it everyday with little help at all.
Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.
Trend Micro's support is pretty decent, we have had issues in the past and they have been fairly responsive to us and our complaints. Depending on how severe the issue was. Any ticket that had a high priority was handled very shortly especially when we contacted our account rep even if it was after hours, we were still able to get support within a short time period.
The online course was simple clear and described the main capabilities of the solution. There is also an initial module that can be done for free so anyone can familiarize themselves with the functionality of this solution. On the other hand, however, there could be more free online courses. Maybe even with a certificate, this would broaden the group of people who are familiar with the platform while increasing familiarity with the solution itself.
Microsoft Sentinel excels in cloud-native scalability, Microsoft ecosystem integration, and AI-driven threat detection with UEBA and Fusion rules, offering faster deployment and lower costs (48% cheaper per Forrester) than Splunk, QRadar, Exabeam, SentinelOne, Securonix, and Wazuh. It lags in third-party integrations and syslog parsing. Organizations choose Microsoft Sentinel for its cost-effectiveness, automation, and Microsoft synergy, especially in Azure-heavy environments, though Splunk and Exabeam lead in flexibility and UEBA, respectively.
I didn't get to fully evaluate Logstash as our corporation was already using Logstash, but both seemed like viable solutions to the problem that we were having. I wanted to evaluate Logstash some more, both did seem like they would work for the business needs that we had, we went with splunk as many teams were already using it.
We selected trend micro to take the AV scans and filtering out of the hands of the Windows and Linux vm's we have deployed and move it to the hypervisor level. This has led us to be able to deploy only a single DSVA per host and can protect all VM"s that are on that hosts. This has allowed for more time being spent on other priority security tasks.
As any cybersecurity product, this has to be more with risk to avoid loss in case of a ransomware that more than relate to a productivity increase. Maybe the impact could be that instead of having people that are checking 24/7 the dashboard, you could implement Sentinel and have less people checking that or people with less expertise. So the saving will be a minor but will be a saving in the cost of your team.
I don't have any numbers to share but Splunk has positively served as a 24/7 monitoring tool that has saved hours of work by self-detecting, saving statistics and alerting problems in the system or from external interfaces as soon as they happen.
Splunk dashboards does a solid job in collecting, analyzing data and creating reports that contain an entire day's activity and then automatically sent out to the business.
Splunk is very easy to learn and very useful to any program or business application.
100% positive ROI. Without Deep Security we would have to leverage and endpoint protection management solution like Sophos or SEPM (Symantec). Although both are good products, from a cost perspective it would have hit us much harder. Trend Micro Deep Security scales very nicely.
Since Deep Security actually has zero (or at least unnoticeable) resource footprint on monitored VMs, it is a huge cost benefit for us. As previously mentioned, actual antivirus clients installed on each virtual machine (VM) would have significantly affected performance. This would have cost us much more additionally in paying for additional resources to allocate over VMs in the VMware environment. Deep Security is almost completely unintrusive from a resource perspective.
Also, from a layered security perspective, it helps us meet our goals; and since the price of Trend Micro Deep Security quite reasonable, it is that much easier to get approval for this specific internal layer of security.
