"A SIEM tool for monitoring real-time security events."
4.5/5
What do you like best about OpenText ArcSight Enterprise Security Manager (ESM)?

ArcSight ESM gives real-time security events from the security devices, network devices, and endpoint machines. The ArcSight connectors support Linux and Windows servers. The microfocus customer support is good and responsive. The User interface of the ArcSight ESM is in classic style. It is easy to assign and annotate the security to the client and senior security analysts. We can integrate the firewall, proxy, Web application firewall, EDR, Servers, IPS, IDS, etc with the Arcsight SIEM Tool. The security analyst can create custom correlation rules and import the most used case for correlation. Review collected by and hosted on G2.com.

What do you dislike about OpenText ArcSight Enterprise Security Manager (ESM)?

The license and pricing model is expensive for small-scale enterprises. Violation of the license usage may result in disabling the searching and reporting feature. The implementation of ArcSight needs skill and support from the vendor to deploy on the IT infrastructure. Review collected by and hosted on G2.com.

"The Pioneer in SIEM"
4/5
What do you like best about OpenText ArcSight Enterprise Security Manager (ESM)?

What I liked about ArcSight ESM was its robust security event management capabilities. It allowed us to efficiently collect, correlate, and analyze security data from various sources, aiding us in quickly identifying and responding to past security threats. The platform's flexibility in customization, alerting, and reporting made it a valuable asset in our previous cybersecurity efforts. Review collected by and hosted on G2.com.

What do you dislike about OpenText ArcSight Enterprise Security Manager (ESM)?

What I didn't like about ArcSight ESM was its complexity and learning curve. It required a significant amount of time and effort to fully grasp its features and functionalities. Additionally, the licensing costs for certain modules or additional features can be quite high, making it less accessible for smaller organizations with limited budgets. While powerful, it may not be the most cost-effective solution for everyone. Review collected by and hosted on G2.com.

What do you dislike about OpenText ArcSight Enterprise Security Manager (ESM)?

The console's UI seems a bit outdated, also, selecting a dashboard or an active channel from the viewer changes the location of all other tabs on it, which is kind of annoying, to me, at least. Review collected by and hosted on G2.com.
