Enhances our security incident investigation but not good for correlation
Investigation is good when you know what you want to search for in Logger. The most difficult part is parsing the logs and configuring the parsers. For investigation, it's good. For correlation, it's not good. We use Sentinel, and Sentinel has pre-built use cases that are much easier to configure. So, it enhances our security incident investigation. We have inbound integration, but configuring the parsers is sometimes very difficult. We only have two use cases where we have a correlation set up. We send the information to Check Point to block IP addresses when we see a lot of blocks from the same source. We have a trigger. So, Logger automatically blocks these IP addresses. We could have Logger put them on a blacklist. So, it offers the ease of integration.

Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
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

"Some of the most valuable features I really appreciate are the performance, how quick the solution is, and how easy it is to create a query."
"Our return on investment for implementing ArcSight Logger over the past 12 months has been positive."
"We haven't had any crashes or bugs. It is stable."
"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."
"The ability to customize the solution in great detail is its most valuable features. We can customize the use cases and also have the ability to do scripting. We can personalize our dashboard as well. The scalability the solution offers is quite impressive."
"The machine learning is a good feature."
"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."
"The most valuable feature for me is Discover."
"Elastic Security makes data communication easier."
"The feature that we have found the most valuable is scalability."
"It can handle millions of loads at a time, and you can always use the filters to find exactly what you are looking for and detect errors in every log message you are searching for, basically."
"Elastic Security is a highly flexible platform that can be implemented anywhere."
"The most valuable thing is that this solution is widely used for work management and research. It's easy to jump into the security use case with the same technology."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"Elastic Security is very customizable, and the dashboards are very easy to build."
"It scales better in the cloud than on-premise."
"The most valuable feature is the custom dashboard feature."
"It has helped us look at modern technology, as well as penetrate our legacy systems, to see where the bottlenecks are."
"The solution is the market leader."
"The most valuable feature is the ability to look at threats and link them to the MITRE ATT&CK framework."
"The feature that I have found most valuable with Splunk is the ability to sift through a bunch of data very quickly."
"The most valuable feature of Splunk Enterprise Security is the comprehensive logging capabilities it provides."
"The solution's most valuable feature is the criticality of alerts."
 

Cons

"The initial setup was a little bit complex."
"The product's connectors should work better and the user manuals need an update."
"You have limited reporting capabilities and I wouldn't choose ArcSight Logger for this purpose."
"It would be better if the product is cheaper."
"The integration with other systems could be improved."
"The console in older versions is not user-friendly."
"I would like to see better scheduling in the next release of this solution."
"The platform is quite expensive. They should reduce its cost."
"We had issues with scalability. Logstash was not scaling and aggregation was getting delayed. We moved to Fluentd making our stack from ELK to EFK."
"It could use maybe a little more on the Linux side."
"Its documentation should be a bit better. I have to spend at least a couple of hours to find the solution for a simple thing. When we buy Elastic, training is not included for free with Elastic. We have to pay extra for the training. They should include training in the price."
"Their visuals and graphs need to be better."
"It would be better if Elastic Security had less storage for data. My customers do not like this. Other vendors have local support in different countries, but Elastic Security doesn't. I would like to have Operational Technology (OT) security in the next release."
"Elastic Security could improve the documentation. It would help if they were more simple and clean."
"Better integration with third-party APMs would be really good."
"The initial configuration and setup are complicated and not straightforward."
"We don't have SOAR products from Splunk. I believe that's an important piece."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
"We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade."
"It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
"We usually have to follow up with technical support on our open cases."
"Splunk could enhance its offerings by incorporating modules for network detection and response and fraud management, along with improving its threat intelligence management capabilities."
"The prices are complicated as we operate in a small third-world country."
"Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."
 

Pricing and Cost Advice

"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."
"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 is an expensive solution."
"I rate the product’s pricing a seven out of ten, where one is inexpensive, and ten is expensive."
"Pricing is reasonable compared to similar tools on the market. They offer perpetual licenses."
"We have a lifetime license, so we don't pay a monthly fee."
"I would rate the product a seven out of ten since it's an enterprise product."
"This is an open-source product, so there are no costs."
"Its price is fine. Its licensing works on a yearly basis. We have to renew the license every year. I also have a good experience with Darktrace. When we buy Darktrace, we get training free of cost, which is not there in Elastic. We have to pay extra for training. There is certainly room for improvement."
"Compared to other tools, Elastic Security is a cheaper solution."
"We are using the free, open-source version of this solution."
"The solution is not expensive and costs around ten dollars a month."
"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."
"The base product is open-source but if you need advanced security features then you need to pay for the subscription. Elastic Security's price is reasonable in some cases and in other cases it's not."
"The solution is free."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"Splunk Enterprise Security is priced lower than competitors."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
"Splunk is not a cheap solution and the license is billed annually."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."
"The pricing model is expensive and a nightmare based on the amount of data."
