The people I normally use for support are very knowledgeable, especially when they help remote in and get to where I need to go and show me much faster and help me understand what I should be doing.
Technology Coordinator at a educational organization with 501-1,000 employees
There is no UK-based support, which leads to delays in waiting for US support.
Senior SOC Developer at XVE Security
If I raise a ticket, it initially goes to the L1 team, but the next level of escalation is really effective.

We do not see any issues with the stability of Microsoft Defender for Identity.
Deputy Manager at Servion Global Solutions
Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.
Instrumentation Engineer at Toyo Engineering Corp
The stability of Securonix Next-Gen SIEM is based on the events we are processing.
Assistant VP, Idm Compliance at a financial services firm with 1,001-5,000 employees
 

Room For Improvement

Microsoft Defender for Identity users seek improved cloud integration, user-friendly features, better support, and streamlined processes for enhanced threat management.
Securonix Next-Gen SIEM needs improvements in user experience, integration, automation, customization, technical support, and compatibility with other technologies.
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.
CyberSecurity Engineer | Information Security Management at Self Employed
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Owner at Alopex ONE UG
Reducing false positives is something we've been working on with Microsoft.
Cloud Security & Governance at a financial services firm with 10,001+ employees
At the admin level, we have many challenges where log parsing is causing issues and compatibility is not present.
Assistant VP, Idm Compliance at a financial services firm with 1,001-5,000 employees
The passing and setup are quite complex at the beginning, making onboarding not smooth.
Senior SOC Developer at XVE Security
SIEM could have better integration with other technologies.
Regional Channel Manager at i2sBusiness Solutions
 

Setup Cost

Microsoft Defender for Identity is cost-effective with E5 licenses despite complex pricing and competitive against other security solutions.
Securonix Next-Gen SIEM offers transparent, competitive pricing based on users, excluding data charges, making it attractive for enterprises.
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.
CyberSecurity Engineer | Information Security Management at Self Employed
Ensuring a fair price according to market standards.
Owner at Alopex ONE UG
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Cloud Security & Governance at a financial services firm with 10,001+ employees
Licensing is based on events per second (EPS), costing between $50 to $60 per EPS.
Regional Channel Manager at i2sBusiness Solutions
The solution is definitely not expensive.
VP International Business and Alliances at a tech services company with 51-200 employees
The pricing has similar ingestion charges compared to other solutions, such as Splunk.
Senior SOC Developer at XVE Security
 

Valuable Features

Microsoft Defender for Identity integrates with Azure to offer comprehensive threat detection, identity protection, and advanced real-time security insights.
Securonix Next-Gen SIEM enhances threat detection through advanced analytics and AI-driven features, reducing false positives and manual efforts.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
Instrumentation Engineer at Toyo Engineering Corp
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.
Owner at Alopex ONE UG
The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks.
Cloud Security & Governance at a financial services firm with 10,001+ employees
The software includes user behavior interactions, dashboards, and training capabilities.
Regional Channel Manager at i2sBusiness Solutions
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.

Protect on-premises and hybrid environments with advanced threat detection and seamless integration
Our Active Directory implementation is a hybrid one. The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks. It identifies lateral movements, privilege escalations, and alerts on potential attacks. The tool is also used for security posture assessment. The seamless integration with other Microsoft solutions within our Microsoft-centric environment is also a major advantage.

Assistant VP, Idm Compliance at a financial services firm with 1,001-5,000 employees
Centralized environment supports big data while facing integration challenges
The customization in Securonix Next-Gen SIEM is more difficult compared to other solutions. At the operation level, we are not facing many challenges with automating things using Securonix Next-Gen SIEM, but at the admin level, we have many challenges where log parsing is causing issues and compatibility is not present. The primary technology challenge we have is not at the security tools level. For example, firewall Cisco and others are capable. However, specific to product, for SAP, we are using certain products, and developing custom connectors for each product, especially the internal applications, is difficult, and Securonix Next-Gen SIEM is not up to the mark.
