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."
"The most valuable feature is the real-time alerts."
"It prevented my users from getting infected by ransomware. It can also pinpoint the story behind every virus or network attack to our environment."
"The real-time analysis adds value."
"We use ArcSight ESM for log analysis and security alerts. It warns us of threats and then helps us conduct a forensic investigation of a cyber attack or internal incident after it happens."
"The out-of-the-box rules that help us configure functioning rules within the environment are valuable."
"Usability is the most valuable feature; the accessibility is quite good, and if a new person wants to be trained in this product, it's easy for them to be trained, as opposed to other products like Splunk or Sentinel."
"The solution has gone beyond signature-based monitoring and analysis and is AI-powered. It is good enough to cover the full range of cybersecurity services."
"This is the best SIEM solution on the market comparing to its competitors."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"HPE ArcSight has a quite steep learning curve."
"Technical support should be improved. Many times, I've raised a case but none of them solved it and it took the guys from the Protect724 forum so solve my issue."
"The roadmap is not clear."
"ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them."
"ArcSight ESM could improve by adding more features and documentation. There needs to be more documentation."
"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."
"The initial setup could be more straightforward."
"High availability achievable through complicated configurations (i.e. load balancers)."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"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 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."
"It's a good price, it's one of the cheaper solutions."
"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."
"The pricing model is expensive compared to open-source alternatives."
"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."
"The pricing is great compared to others."
