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

"The tool aggregates logs. We can see the logs in one place."
"We use the solution to collect logs."
"The product is quite mature. It's been around for a long time."
"Very good real-time reporting with a good dashboard."
"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."
"It greatly changed our work habits in the organization allowing us to not only trace back security threats, but also to generate usage trends, discover anomalies and so many other usages."
"It has improved our organization because we had many investigations that it helped us with."
"If you're looking for a single product that will let you aggregate, correlate and analyze many different sources in a single place, then there are few competitors that can come close to ArcSight's features."
"We help our customers do more than 'check a box' for security and compliance and we are very proud of that."
"It has helped us to gather, store, correlate and analyze security log data from many different information systems."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"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 weakness in this system comes about because, with so many different logs, it is possible that the security analyst will lose information."
"As of now, if we are evaluating our own scenario, we are not even thinking about it."
"ArcSight ESM is not easy to use and it should be integrated with other tools that have infrastructure capabilities."
"Licensing is straightforward, but the solution is fairly pricey."
"The user interface of ArcSight Enterprise Security Manager could improve. It is not very good. Additionally, they could integrate the web interface better."
"Best SIEM product but it's high on pricing and licensing."
"Sometimes, it takes ages to get an issue resolved. I have ArcSight experience, so I normally try to fix things on my own or find a workaround, but it's tough to get support when I need it."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"The product licenses are inexpensive."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"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 is great compared to others."
"The solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"Aggregation can help a lot in pushing down licensing costs."
"There is a license required for this solution."
"ArcSight can be a little bit expensive because of the area that we work in and the cost. Licensing is mostly on a yearly basis, not monthly."
