OpenText Enterprise Security Manager (OpenText ESM) and Trellix Enterprise Security Manager (Trellix ESM) compete in the enterprise security management sector. Trellix ESM seems to have the upper hand in ease of use and user-friendliness, appealing more to users for daily operations.
Features: OpenText ESM is known for its high event ingestion capability, robust correlation, and support for multiple log sources, providing a customizable and integrable platform. Trellix ESM offers pre-built correlations, dashboards, and reports, enhancing its ease of use while supporting diverse data inputs.
Room for Improvement: OpenText ESM struggles with significant customization requirements, a complex installation process, and could improve API integration and support services. Trellix ESM faces integration challenges with SaaS solutions and could enhance its stability and reduce resource demands, alongside improving support services and documentation.
Ease of Deployment and Customer Service: OpenText ESM primarily deploys on-premises but also supports hybrid and cloud setups, requiring expertise that complicates deployment. Its customer service needs better initial problem resolution and response speed. Trellix ESM, also mainly on-premises with hybrid cloud support, benefits from easier setup but faces similar customer service issues regarding timely resolutions.
Pricing and ROI: OpenText ESM is generally seen as expensive, with costs influenced by event volume and deployment complexity; however, the functionality is valued by users who find the cost justified. Trellix ESM offers a scalable pricing model, making costs reasonable compared to competitors like IBM QRadar. Users find significant value and ROI in security management despite initial expense.
If I raise a P1 or P0 ticket, the response time is often delayed by four to eight hours.
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.
It lacks some capabilities compared to other tools available in the market.
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.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools.
The ability to interpret data is highly valued.
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.
