OpenText Enterprise Security Manager and Microsoft Sentinel compete in the enterprise security management category. Microsoft Sentinel has an upper hand due to its strong automation, integration, and machine learning capabilities.
Features: OpenText Enterprise Security Manager offers powerful correlation capabilities, support for various devices, and real-time monitoring through comprehensive dashboards. Microsoft Sentinel provides seamless integration with Microsoft products, extensive machine learning, and a cloud-native platform for a single-pane-of-glass experience and advanced threat detection.
Room for Improvement: OpenText Enterprise Security Manager could enhance its UI design, simplify complex setups, and improve technical support to overcome its learning curve. Microsoft Sentinel needs to improve cost transparency, third-party integration, and to enhance its AI capabilities, addressing user concerns about complex pricing.
Ease of Deployment and Customer Service: OpenText Enterprise Security Manager's on-premises or hybrid deployment requires significant infrastructure, making it complex, with varied customer service experiences. Microsoft Sentinel is cloud-based, allowing quicker deployment, especially for Azure users, with generally favorable support and extensive online resources.
Pricing and ROI: OpenText Enterprise Security Manager is seen as expensive and suitable for large enterprises with the budget for its capabilities, although it offers significant value in compliance and threat detection. Microsoft Sentinel has a consumption-based pricing model, offering flexibility and potentially better ROI when tailored to data ingestion needs within existing Microsoft ecosystems, despite perceptions of its high costs.
If a customer is already using Microsoft’s ecosystem, the ROI can be positive due to seamless integration.
Our MTTR, mean time to response, improved by forty to fifty percent. Earlier, medium-severity incidents took two to three hours to resolve. Now, after Microsoft Sentinel, it is forty to fifty-five minutes.
For example, time saving on incidents is 40 to 50%, and previously, incident analysis took two to three hours, whereas now it takes 30 to 60 minutes.
Microsoft invests significantly in support, which is crucial for companies.
I believe Microsoft could improve by keeping customer service within the US for Microsoft Sentinel customers who are within state and federal government sectors.
Working with a Sentinel engineer helped us tune settings effectively.
If I raise a P1 or P0 ticket, the response time is often delayed by four to eight hours.
There is no need to add hardware or redesign infrastructure because it is cloud-native.
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.
It lacks some capabilities compared to other tools available in the market.
I have never experienced any downtime, crashes, or performance issues with Microsoft Sentinel because it is SOC as a Service, so it maintains 100% uptime and scaling.
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.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
Log ingestion and retention costs can grow quickly, and understanding which data source is driving cost is not always straightforward.
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
It has been beneficial that Microsoft Sentinel is included as part of the Microsoft package, making it more cost-effective.
Microsoft Sentinel is not a low-cost SIEM.
Microsoft Sentinel is provided at no cost, so we didn't have any issues with the cost.
ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools.
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 ability to interpret data is highly valued.

Microsoft Sentinel offers cloud-native SIEM and SOAR capabilities with AI-powered threat detection, automated responses, and integration with Microsoft products. It is designed for comprehensive threat management with flexible deployment and scalability.
Microsoft Sentinel provides centralized management of cloud-based security monitoring and incident detection. Leveraging AI capabilities, it enhances threat intelligence and automation, allowing users to streamline security operations across cloud and on-premises systems. Microsoft Sentinel efficiently aggregates logs, correlates security events from multiple sources, and integrates seamlessly with Microsoft security offerings such as Defender. While its flexible deployment options and robust automation through playbooks are advantageous, users may encounter challenges with integration outside of Microsoft products, potential log ingestion delays, and a complex query language. The platform would benefit from enhanced speed, a simplified interface, improved query performance, and stronger documentation support.
