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."
"Correlation capabilities: This product provides an advanced level of correlations, which is highly valued."
"The correlation feature is good."
"I think that the overall experience with this solution is good, but in particular, I think that the dashboards are quite interactive."
"The best feature of ArcSight is its flexibility, as almost no other vendor provides such a good framework to collect, parse, and analyze data, and I've found ArcSight's correlation engine to be the most advanced on the market."
"It is easy to use when we created some dashboards for analytics."
"SmartConnector: Normalization parses raw logs and converts them into CEF (common event format). This is the core of the product."
"It gives better overall visibility. Before, we didn't have a unified system for managing security alerts. ArcSight introduced various alerts, giving us a better visibility of potential problems."
"We have been satisfied with the support."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"They need to improve the Web UI, similar to how it is done with Splunk."
"High availability achievable through complicated configurations (i.e. load balancers)."
"I tried to learn the syntax in order to customize the software (connectors and agents) for a particular device, and it was a nightmare."
"I will like to see a threat analytics module. Also, the ability to produce reports."
"What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature. That feature should be more powerful and have more correlation in terms of AI/ML, though MicroFocus has done a good job in adding analytics to ArcSight Enterprise Security Manager (ESM) which has become a big draw to customers. What I'd like to see in the next release of the solution is the addition of AI/ML features."
"Although we're able to customize it, it requires some level of subject-matter expertise for all the special adapters for collection."
"ArcSight is a very old and mature product that is running on an old platform."
"There are a lot of improvements that need to be made, too many to mention all of them, but some improvements with the Con App would be a good start."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"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 pricing is great compared to others."
"Pricing is good, I'd rate the pricing a seven out of ten, with ten being low price. It's better than Splunk and IBM QRadar because their pricing is based on EPS."
"Price-wise, ArcSight ESM was a bit high compared to competitors, which factored into our decision to switch to Splunk. It couldn't cover all our business needs for what we wanted to implement."
"Aggregation can help a lot in pushing down licensing costs."
"We're paying a fee for an MSSP, and the cost of the total cost of ArcSight ESM was approximately three to four million dollars a year. The price was less than similar solutions. We did not have additional fees."
