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.

AI triage has streamlined real-time alert monitoring and has improved on-call incident response
The best features Panther offers are AI Triage, the ability to comment on our activities, and seamless integration with other communication sources such as PagerDuty, Microsoft Teams, and potentially Slack, showcasing the flexibility we have in using this tool. The most valuable feature for my team is definitely AI Triage, which helps save a lot of time by eliminating the need for manual research regarding patterns that may be repeated, making our work easier and more efficient. Panther has positively impacted my organization as it serves as one of the main sources for triaging real-time incidents. Panther definitely plays a key role in the work that we do. Specific outcomes that show how Panther has helped our organization include saving a lot of time, especially since the AI Triage feature reduces the necessity to reach out to others for clarity, which it occasionally accomplishes on its own. To be honest, it does lack some aspects. For example, if it could access our organizational knowledge, including the Jira database, it might better analyze incidents and determine whether they are false positives or not by using more contextual data.

Quotes from Members

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

Pros

"The tool is good for correlation and aggregation. We use it as a collection platform."
"ArcSight Enterprise Security Manager (ESM) works perfectly. It's a stable and scalable product."
"ArcSight is better than them all when it comes to filtering, normalization, aggregation, dashboards, reporting and correlation, multi-tenancy and custom devices support."
"The product is quite mature. It's been around for a long time."
"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. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"The solution is very good at consolidating logs from a variety of sources."
"This is the best SIEM solution on the market comparing to its competitors."
"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 AI Triage feature saves a considerable amount of time, and if it were to incorporate organizational knowledge, it could provide finer-tuned results."
"I find Panther's detection capabilities and integrations to be highly valuable."
"We have seen a return on investment measured primarily through SOC efficiency and productivity improvements, with teams observing a twenty to thirty-five percent improvement in investigation efficiency depending on the environment and product maturity."
 

Cons

"The roadmap is not clear."
"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."
"The onboarding process for this solution could be better. It also needs a better GUI."
"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."
"HPE ArcSight has a quite steep learning curve."
"It would be nice if the interface were more user-friendly, with, for example, a minimal number of tabs to navigate."
"The API integration could be better, and I'd like to see more machine-learning capabilities in the future."
"The stability of ArcSight Enterprise Security Manager (ESM) is not very robust; I need to monitor all components present in the SIEM daily."
"The solution could be improved by providing more built-in integrations, which would reduce the need for me to build them myself."
"Regarding Panther's accuracy and reliability of output, I would rate it at 70 percent since, at times, it identifies findings as valid when they may actually be false positives, which we have experienced in a few cases."
 

Pricing and Cost Advice

"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"The product licenses are inexpensive."
"The pricing model is expensive compared to open-source alternatives."
"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."
"There is a license required for this solution."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"​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."
