Featured Reviews

Nagendra Nekkala. - PeerSpot reviewer
A scalable and stable solution that enables users to see all the event logs in one place
The technical support team is very slow. The support persons do not take prompt action. They take too much time to implement new changes. Even if we tell them that we are not able to get critical logs, they take almost three to four days to provide a resolution. The support is not good.
Md. Shahriar Hussain - PeerSpot reviewer
Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"In terms of ArcSight Logger's most valuable feature, it is their scalability. ArcSight's real advantage is its scalability because they have two layers, including the logger layer."
"It provides in-depth information on business activities once we log into the system."
"It's a robust, mature product and you can do some really complex operations and analytics."
"I am impressed with the product's ability to pick up logs. It also has UEBA which has reduced the time to take charge of the events."
"The technical support team is good...It is a scalable solution."
"The most valuable feature is the level of detail that you can see about certain events, even when they do not come up in the console."
"We haven't had any crashes or bugs. It is stable."
"The log digestion features from threat intelligence platforms like Recorded Future or Talos are valuable."
"Senses, tracks, and links significant incidents and threats."
"The most valuable feature is the DSM Editor. The custom parsing tool is very nice, outstanding."
"The initial setup is not complex or difficult."
"There are a lot of great out-of-the-box features included."
"It is very stable. We have not faced interruptions in the past four and a half years."
"Due to the skills shortage, we are able to use it from the standpoint of bringing in a lower level employee or a person who may not have security knowledge."
"It can analyze event logs, event security, and give a good consult."
"Technical support is good overall."
"The most valuable features of Splunk Enterprise Security are reporting capabilities. It is a good tool for checking systems and analyzing situations. I find it useful to check my systems and analyze situations."
"Out-of-the-box, it seems very powerful."
"Capability to expand the functionality through custom code for data inputs, commands, visualization, alerts, and machine learning."
"The most valuable feature of Splunk is the management and built-in workflows."
"I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
"The most valuable features include the incident review and Dashboard Studio."
"I have not seen any outages in the product in the past two years that it has been running in our company, so I think it is good when it comes to the stability part."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
 

Cons

"The solution must provide readymade connectors for different applications."
"The solution should make it possible to integrate network analysis features."
"I would like to see better scheduling in the next release of this solution."
"The product's connectors should work better and the user manuals need an update."
"The console in older versions is not user-friendly."
"The platform is quite expensive. They should reduce its cost."
"I think the ArcSight team should try to simplify legacy products for the customers, because that product is not easy to use or to work with. It needs more more competency or appeal to use. We hope Micro Focus is trying to resolve this."
"It is really difficult to work in ArcSight Logger, as it is very slow."
"For future updates, I'd like to see more advanced threat intelligence features integrated with AI. This would help with analyzing traffic patterns and improving protection. QRadar currently doesn't integrate with AI for threat analysis. However, AI could enhance its capabilities by learning traffic patterns and automatically blocking or quarantining suspicious traffic. This would be especially useful when administrators are not actively monitoring. AI could help by analyzing incoming and outgoing traffic and adjusting policies accordingly."
"IBM QRadar could improve the plugins and threat detection."
"I need a solution which will send alerts in the event of any behavior."
"In a future release, the solution could provide malware analysis."
"It is not app based."
"The custom rules could be simplified more or it should be possible to use a different language, other than the ones that the solution is already using. They should add other languages into the mix."
"They have to build more quantitative monitoring, profiling, and make it more predictive."
"IBM Qradar could improve the reporting. The tool is not designed to report. It's a great operational monitoring tool. You put it on a screen and you watch it. If you want to have analytics out of it, that's a whole different story. You're going to need more people and tools. What should be added is reporting and integration into Power BI, into some capability that produces analytical reports from the source data. IBM does not seem to care to add these features."
"While Splunkbase (the app repository) has a lot of great content, some apps are terribly old and could stand to be updated or purged."
"It's costly."
"The use cases provided by Splunk are a good starting point, but could cover many additional topics to ensure that a smaller or less experienced shop might maximize the value of an ES deployment."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
"It is important to make sure that everything is built off of the threat models and all the underlying items within Splunk."
"Being a SIEM solution with a centralized dashboard, we would like to have more options to customize it."
"Splunk Enterprise Security should provide a better and richer integration."
"Free-floating panels in the dashboards are like a glass table."
 

Pricing and Cost Advice

"The pricing is quite harsh."
"It's not cheap at all as it's a big product and has been in the market for quite some time now."
"ArcSight Logger is very expensive compared to their competitors, but when we talk to the customer and explain what the features are and how we can scale, they understand. Still, ArcSight is more expensive than the competition."
"ArcSight is an expensive solution."
"I would rate the product a seven out of ten since it's an enterprise product."
