OpenText Enterprise Security Manager and SentinelOne Singularity AI SIEM both compete in the security solutions category. SentinelOne stands out for its advanced features and perceived long-term value, despite OpenText offering a more attractive pricing model and strong customer service.
Features: OpenText Enterprise Security Manager provides comprehensive incident management, extensive reporting capabilities, and supports a wide range of integrations. SentinelOne Singularity AI SIEM offers AI-driven threat detection, fast response features, and advanced threat management capabilities.
Room for Improvement: OpenText could enhance its deployment speed and improve cloud support. Adding more advanced AI capabilities and integrations could further strengthen its position. SentinelOne benefits from expanding its customer support response times and enhancing its reporting capabilities. Further ease of use improvement in setup processes could be beneficial.
Ease of Deployment and Customer Service: SentinelOne uses a cloud-based deployment model for quicker setups and updates, making it favorable for its flexibility. OpenText may require a longer, traditional deployment process but is known for faster customer service resolutions.
Pricing and ROI: OpenText Enterprise Security Manager is more cost-effective initially, offering rapid ROI for budget-conscious businesses. SentinelOne involves a higher initial investment but promises a higher long-term ROI due to its effective threat reduction capabilities, appealing to those focusing on long-term strategic investments.
I find that using ArcSight Enterprise Security Manager (ESM) provides a valuable return on investment as it serves as a single point of glass for logs and data analysis.
If the data gets encrypted, it automatically rolls back.
Before using SentinelOne Singularity AI SIEM, investigating a moderately complex alert took around thirty to sixty minutes because analysts had to collect logs from multiple security tools.
SentinelOne Singularity AI SIEM has reduced our response time to true positive alerts by approximately forty percent through automation.
If I raise a P1 or P0 ticket, the response time is often delayed by four to eight hours.
I would rate the technical support of ArcSight Enterprise Security Manager (ESM) a nine as they are always available and responsive whenever we open a case.
SentinelOne Singularity AI SIEM has AI-based technical support available.
Based on my experience with the technical support of SentinelOne Singularity AI SIEM, I would rate them a ten.
In rating the technical support for SentinelOne, it depends on whether we are discussing EDR or SentinelOne Singularity AI SIEM.
It lacks some capabilities compared to other tools available in the market.
It is easy to scale, and I have not encountered any issues when we require more storage or deployment.
It is designed to handle growing log volumes and supports environments that include on-premises infrastructure, cloud services, endpoints, identity platforms, and network devices.
With any AI adoption, the end goal should be more governance and data security and safety.
The performance depends on the configuration.
I would rate the stability of ArcSight Enterprise Security Manager (ESM) a nine because I have not encountered significant issues, unlike other solutions that sometimes have database errors.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
I have worked with it, and it is very handy, easy to manage, and excellent with its AI-driven capabilities.
When it comes to stability, I would give SentinelOne Singularity AI SIEM a nine.
In terms of performance stability, I have never had any crashes, downtimes, or performance issues.
I would like to see the detection and response features included in the next release of ArcSight Enterprise Security Manager (ESM), as security orchestration and automation are increasingly important.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.
The interface flickers frequently, and sometimes it does not load properly.
Whenever OT security comes into the picture, the customers do not allow us to integrate their OT devices on a cloud. It should be available on-premises because the OT SIEM market, in the India market for instance, is something around a four to eight billion dollar market.
ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools.
I would rate the pricing of ArcSight Enterprise Security Manager (ESM) around seven, as it varies based on features and demand, making it more affordable for larger organizations, while smaller ones might find it expensive.
I find SentinelOne's pricing to be reasonable and competitive.
Features such as centralized log management, AI-driven analytics, automated workflow, and integrated security options can reduce operational overhead and improve SOC efficiency, which helps justify the investment.
Compared to another SIEM tool's pricing, the pricing is the best, from my side.
The ability to interpret data is highly valued.
The log analysis feature is particularly valuable as it allows analysts to interpret intrusion-related logs efficiently.
We finally have visibility into things that were never visible before.
It employs a combination of AI and ML to check for viruses or any other malicious processes, including fileless attacks.
The AI-driven threat detection capabilities improve our overall security posture.
