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
6.7
Microsoft Defender for Identity improves incident management, reduces costs, enhances ROI, and saves time despite unclear financial benefits.
Sentiment score
5.2
Securonix Next-Gen SIEM delivers ROI through cost savings, operational efficiency, quick deployment, and enhanced threat detection in compliance environments.
The solution is time-saving, particularly in the long run after it is deployed, enabling us to get value promptly.
 

Customer Service

Sentiment score
8.4
Microsoft Defender for Identity's support receives mixed feedback, with users praising premium service but noting poorer lower-tier support responses.
Sentiment score
6.7
Securonix Next-Gen SIEM excels in customer service with high satisfaction ratings, proactive guidance, and effective issue resolution.
The quality of support is very good, but troubleshooting can take time due to complex setups and the need to provide many logs.
Generally, the support is more effective than other providers like Oracle.
There is no UK-based support, which leads to delays in waiting for US support.
If I raise a ticket, it initially goes to the L1 team, but the next level of escalation is really effective.
When we reach out to someone, we often wait for the right person with the right skills to come and fix the solution, which is the major challenge.
 

Scalability Issues

Sentiment score
8.6
Microsoft Defender for Identity is scalable, efficiently supports large networks, and integrates well into Microsoft-centric environments with minimal effort.
Sentiment score
8.0
Securonix Next-Gen SIEM offers efficient scalability with flexible options, resolving slowdowns swiftly for diverse operational needs.
In a Microsoft-centric organization, especially with Azure infrastructure and Office 365, Microsoft Defender for Identity is scalable.
I can rate it around eight to nine, and it is very scalable and capable of handling tasks, especially for the on-premises product.
The solution is scalable as it is cloud-based and cloud-native.
 

Stability Issues

Sentiment score
7.8
Microsoft Defender for Identity is stable and reliable, though occasional sensor restarts occur, generally scoring 6-9/10 in stability.
Sentiment score
7.8
Securonix Next-Gen SIEM is stable with high availability, efficient log management, and high user satisfaction despite occasional issues.
Microsoft Defender for Identity is quite robust and built on Azure hyperscale infrastructure, with a 99% availability.
Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.
The stability of Securonix Next-Gen SIEM is based on the events we are processing.
 

Room For Improvement

Microsoft Defender for Identity needs better integration, usability, and support, with improved detection and cost efficiency highlighted by users.
Securonix Next-Gen SIEM struggles with complex deployment, integration, usability, and needs improvements in reporting, support, pricing, and performance.
If Microsoft could develop a feature that indicates when impossible travel is caused by VPN connections, it would prevent unnecessary password resets and session disruptions, especially for VIP users in organizations.
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Reducing false positives is something we've been working on with Microsoft.
At the admin level, we have many challenges where log parsing is causing issues and compatibility is not present.
The passing and setup are quite complex at the beginning, making onboarding not smooth.
When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck.
 

Setup Cost

Microsoft Defender for Identity is cost-effective within E5, offering flexibility compared to standalone purchases or E3 add-ons.
Securonix Next-Gen SIEM offers competitive, predictable pricing based on employee count, with typical enterprise costs around $100,000 for three years.
If they can reduce the costs, organizations will be happy, and it will compensate for using the Azure environment, which is more expensive on the infrastructure as a service side.
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Ensuring a fair price according to market standards.
Licensing is based on events per second (EPS), costing between $50 to $60 per EPS.
The pricing has similar ingestion charges compared to other solutions, such as Splunk.
 

Valuable Features

Microsoft Defender for Identity excels in integration, real-time detection, privilege management, AI analytics, and comprehensive security monitoring features.
Securonix Next-Gen SIEM offers advanced threat detection, automation, and integration, enhancing security while reducing manual tasks and response times.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
I find the most valuable features in Microsoft Defender for Identity to be the conditional access and the rule-based access control to give users their actual role-based permission to work.
The most valuable feature is its hybrid artificial intelligence, which gathers forensic data to track and counteract security threats, much like the CSI series in effect.
Now, the process is automatic, reducing our workload.
The other SIEM solutions lack an option for big data analysis, whereas in the Securonix Next-Gen SIEM, we have this option.
The software includes user behavior interactions, dashboards, and training capabilities.

Integration within the ecosystem enhances collaboration and automates functionalities
The integration into the Microsoft Defender ecosystem is the most valuable feature of Microsoft Defender for Identity. It fits very nicely with all the other Defender tools, allowing for excellent collaboration among them. It also fits seamlessly into Microsoft Sentinel SIEM. Furthermore, Microsoft security solutions can save time as they allow the automation of numerous functionalities, and the reporting inside the Microsoft ecosystem is commendable.
Mohammed Nadeem Rais - PeerSpot reviewer
The visibility and analytics from Securonix SIEM have become indispensable in identifying and stopping potential threats before they escalate.
The most valuable feature of Securonix Next-Gen SIEM is its advance analytics, flexibility and scalability. We ingest billions of logs without worrying about resource allocation. This makes it a robust and cost-effective solution for our needs. Its user entity and behavior analytics (UEBA) are also integral for detecting insider threats and lateral movements within the organization. These features help organizations strengthen their security posture, protect sensitive data, and maintain compliance with strict regulatory requirements.
