HPE ArcSight Review
CEF log formatting helps with combining events from different sources. It can be quite complicated for the "non-IT" user.


Valuable Features:

Correlation and data normalization via CEF: The speed of ArcSight's correlation engine, together with data enrichment, makes it a great tool for exploring vast amounts of data. Other SIEM tools have a hard time giving the same results at the same speed. Also, thanks to CEF log formatting, combining events from different sources takes minimal effort. Whereas, setting up that normalisation on other SIEM competitors could take countless hours.

Room for Improvement:

Ease of use, access and simplicity: HPW ArcSight makes it hard to capitalize on reports without the use of the console. Other SIEM tools have made it clear that event correlation results can be used not only to send out alerts, but also to provide easily accessible results to management.

ArcSight can be quite complicated to use for "non-IT" user. In terms of "ease of use", access and simplicity, HPE could do a better job, since customers acquiring the product should be spending more time on implementing use cases than on understanding the product and the console organization.

Also, in terms of installation, we are no longer in an era where installing a product should be a laborious process. Instead, it should be simple and fast.

Also, when it comes to data onboarding, managing ArcSight connectors in a multi-technology environment, there is no simple way to guarantee that data parsing is happening properly.

Finally, having simple-to-set-up, multi-site high availability, in contrast to single-site HA, would be very welcome.

Use of Solution:

I’ve been using ArcSight for three years.

Stability Issues:

We have had some issues on the SmartConnector layer, since not all parsers provide perfect results (especially in the case of proxy data). Also, there have been some issues on the HA modules, since HA works sort of like a local r-sync (no remote HA).

Scalability Issues:

No scalability issues have been encountered so far. ArcSight's architecture is very scalable, especially when set up in a layered architecture.

Technical Support:

Support is slow and doesn't always have the required skill set to solve the issues.

Previous Solutions:

We did not have a previous solution.

Initial Setup:

Initial setup was very complex. Any modification to the OS prior to ESM installation may cause errors in installation. Most errors aren't explicit and require a lot of time, effort and sometimes PS help to solve.

Cost and Licensing Advice:

Price is fair compared to other SIEMs (Splunk, QRadar, etc.). It's not the go-to product if you are looking for something cheap. Go for ArcSight, if it provides specific features that your IS requires.

Other Solutions Considered:

Before ArcSight, we looked at QRadar and Splunk.

Other Advice:

My first advice is "be patient". It takes a lot of time to deploy an ArcSight infrastructure, but the result is worth it. Technically, it’s a very powerful tool. It would be worth it to take the time to learn some of the hidden features.

Disclosure: I am a real user, and this review is based on my own experience and opinions.
