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

"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 webpage algorithm is the most valuable feature because it was the fastest feature for searching the logs, events, and correlation."
"ArcSight ESM allows us to find if someone is doing an administrative operation at inappropriate times of day or trying to do something they're not allowed to."
"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 am satisfied with the solution's stability."
"The solution enables you to monitor logs and to analyze data, but you can also use additional add-ins such as reputation services that can integrate ArcSight ESM with tipping point IPS."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"By using ArcSight ESM and its correlation technology, it thwarts multiple attacks from external sources before exploitations such as SQL injection, UNIX password file attempt, brute force to published servers, and more."
"Panther positively impacts my organization as it is the first point of response for any incident, giving a reviewer full clarity about what is happening, how it is happening, and where it is happening."
"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."
"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."
 

Cons

"ArcSight ESM needs to improve performance, user interface, and automation."
"The user interface of ArcSight Enterprise Security Manager could improve. It is not very good. Additionally, they could integrate the web interface better."
"The security is difficult. I would like to have a feature that gives us an entire report listing what devices are integrated."
"There are several improvements that we would like to see, including: Building a system based on a log collection (SOC), a scenario for external encroachment, and Operator training."
"For somebody who is new and just starting with this product, they find it really tough."
"They need to improve the Web UI, similar to how it is done with Splunk."
"Micro Focus does not have a physical presence here in Pakistan, although IBM does."
"OOB content is limited Microfocus should release the smart connector update on quaterly basis."
"The user experience could be improved because whenever I want to investigate the data, too much data is shown in the UI."
"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."
"The solution could be improved by providing more built-in integrations, which would reduce the need for me to build them myself."
 

Pricing and Cost Advice

"It's a good price, it's one of the cheaper solutions."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"There is a license required for this solution."
"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."
"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 solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"The pricing model is expensive compared to open-source alternatives."
