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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"We do consulting and I get feedback from our clients that the product really helped them with compliance, especially with GDPR."
"It's a fantastic product and highly configurable, but it needs nothing less than a seasoned cyber security professional with serious engineering expertise and a real desire to provide meaningful use cases."
"The solution is very good at consolidating logs from a variety of sources."
"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."
"The simple fact that HPE ArcSight helped us several times to survive malware attacks (Conficker was one such attack) and it also helped a lot with different compliance audits, which was enough for us."
"I think that the overall experience with this solution is good, but in particular, I think that the dashboards are quite interactive."
"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."
"We help our customers do more than 'check a box' for security and compliance and we are very proud of that."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"It would be nice to have it on the cloud so that you can deploy it easily, saving time and resources."
"Best SIEM product but it's high on pricing and licensing."
"The security is difficult. I would like to have a feature that gives us an entire report listing what devices are integrated."
"As of now, if we are evaluating our own scenario, we are not even thinking about it."
"Make sure you tune it to your business and infrastructure, which isn't necessarily part of technical support."
"The initial setup could be more straightforward."
"The stability isn't quite perfect. We occasionally run into problems."
"When I asked our networking juniors for a comparison between LogRhythm and ArcSight, they said that both platforms are almost the same. It is just that LogRhythm is more modern with a digital platform, which probably gives it some advantage over ArcSight. ArcSight is a very old and mature product that is running on an old platform. It is an old legacy platform. In terms of new features, it just requires platform upgrades so that it becomes lighter and easily adaptable, specifically in the cloud. It would be a good thing if they can also make reporting easier."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.​"
"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."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"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."
"The product licenses are inexpensive."
"It’s a single license platform."
