Executive SummaryUpdated on Sep 18, 2024

Review summaries and opinions

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

ROI

Sentiment score
7.1
Microsoft Sentinel offers mixed ROI, improving efficiency and security, with high initial costs but potential positive long-term returns.
Sentiment score
3.2
In-house teams claim McAfee offers high ROI, but executives struggle to see it without C-level focused reports.
If a customer is already using Microsoft’s ecosystem, the ROI can be positive due to seamless integration.
We attribute our growth to Sentinel.
From a risk perspective, it's about mitigating risk, and as mentioned earlier, we haven't missed many things since we've had the offering in market—only a couple of minor incidents.
 

Customer Service

Sentiment score
6.6
Microsoft Sentinel support is generally positive, with quick responses and valuable documentation, though high-tier issues exist.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
Their solutions' integration simplifies resolving issues compared to those caused by third-party products.
Working with a Sentinel engineer helped us tune settings effectively.
When my team needs to escalate issues to Microsoft, especially for Microsoft Sentinel, the response is fast through their French entity.
I would rate support for Trellix ESM 10 out of 10 because if we connect with the support in the UK, we get excellent support.
It's rare for me to need them unless it's an issue with licensing, and they are the best in that regard.
 

Scalability Issues

Sentiment score
7.9
Microsoft Sentinel efficiently scales in diverse environments with easy integration, automatic scaling, and satisfactory performance, despite cost concerns.
Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
Office 365 and Exchange are running on it, covering about 35,000 users efficiently.
As our organization uses Microsoft Azure and Defender, everything grows together, and we can integrate various features seamlessly.
Being a SaaS solution, the scalability of Microsoft Sentinel is robust.
Scalability is quite easier with Trellix ESM, because all we need to do is add more receivers to it, so it can go to any point.
 

Stability Issues

Sentiment score
7.8
Microsoft Sentinel is stable and reliable, with minimal downtime, excellent uptime, and occasional minor manual interventions needed.
Sentiment score
8.3
Trellix ESM is generally stable with effective support, though some users experience bugs and interruptions affecting reliability.
So far, we have not experienced any issues, and it has been stable from the beginning.
In the past two years, our team hasn't encountered any issues with the stability of Microsoft Sentinel from an operations perspective.
I need to be aware of deprecated connectors as they may disconnect, but the data continues to be sent with a need for quick adaptation.
 

Room For Improvement

Microsoft Sentinel users desire better integrations, clearer features, improved speed, enhanced AI, and streamlined processes for effective use.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Currently, we are happy to have a way in the middle with not so much cost, but it would be nice to have the ability to enhance the automation of workflows based on learned incidents.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
 

Setup Cost

Microsoft Sentinel's cost perception varies, offering flexibility and integration benefits, yet data volume can significantly impact expenses.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Microsoft Sentinel offers more capabilities than Bastion, with a more intuitive experience.
Setting up the right cost model for customers is intricate, requiring careful consideration of various components and licensing tiers.
The ingestion costs for the data analytics is usually the highest cost.
 

Valuable Features

Microsoft Sentinel integrates seamlessly with Microsoft tools, using AI for threat detection, automation, and providing comprehensive threat management.
Trellix ESM excels in real-time threat detection, user-friendly interface, quick deployment, and strong integration with other technologies.
Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.
Microsoft Sentinel has improved cost efficiency, which is one of the key areas we're able to win business against the ability to have threat intelligence.
Microsoft Sentinel's ability to correlate data from multiple sources enhances our threat detection capabilities beyond what is a simple data lake solution by filtering out the noise and consolidating the signal down to a meaningful level that is easier to investigate and see.
The weakest point is it doesn't cover almost all the devices, so the customer has to be more dependent on the parsers to be written by the Professional Services team.

Ivan Angelov - PeerSpot reviewer
Threat detection and response capabilities enhance investigation processes
My security team has been using Microsoft Sentinel for around two years. We also have Bastion and SolarWinds as part of our monitoring tools. We use a three-way tool, alongside Microsoft Sentinel, in our environment The most valuable features for us include threat collection, threat detection,…
Daniel Durian - PeerSpot reviewer
Helps to monitor and detect cyberattacks
The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick. Trellix ESM provides situation awareness. On the dashboard, I can see outbound and inbound communications to known threat hosts, IPS/IDS activity, and threat intelligence of the perimeter defense in the firewall. This information helps preempt attacks.
