Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.

Unified log analysis has strengthened incident detection and supports continuous attack simulation
I do not have any areas for improvement in ArcSight Enterprise Security Manager (ESM) as I have not delved deeply into it; overall, it is a good package. 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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
"It has improved our organization because we had many investigations that it helped us with."
"The dashboard is the most valuable feature for us as it can show a lot of information about real-time incidents."
"I really like the correlation part and the way the logs are correlated; I have never faced issues with parsing in this product, and I like the way it parses, and everything is so clear to me."
"The real-time analysis adds value."
"The reports that we are from getting from ArcSight are very valuable, the reporting in ArcSight is good, our regulators ask us for the reports on a regular basis, and we have been able to provide the required data."
"Allowing for non conventional data feeds from HR into our overall security monitoring practice has allowed us to catch gaps in our exit checklist for employees among other things."
"On the positive side, ArcSight ESM's performance was excellent. It was very fast when writing queries. It provided good performance monitoring and had built-in rules to show which rules triggered most often and impacted performance. This performance monitoring was well-implemented."
"ArcSight ESM helps us stop security incidents by detecting them early before they can cause more damage."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"The product should include a lot more predefined scenarios so the adopted company will have knowledge and a broader skill set in security and network."
"HPE ArcSight has a quite steep learning curve."
"The security area has room for improvement."
"Honestly, I won't recommend the ArcSight to another person."
"The stability of ArcSight Enterprise Security Manager (ESM) is not very robust; I need to monitor all components present in the SIEM daily."
"The only concern is that AI needs to be integrated"
"User behavior analytics is too pricey but an essential tool."
"What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"The licensing cost is affordable if you get an enterprise license. The licensing is based on EPS, so you can probably provide a package of license for multiple ESMs with their correlational end fees. It is cost-effective."
"There is a license required for this solution."
"The product licenses are inexpensive."
"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
