Facilitates backend service monitoring with efficient log retrieval and API flexibility

Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency

The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Quotes from Members

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

Pros

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"The ability to write custom alerts is key to information security and compliance."

"Open source and user friendly."

"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."

"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."

"I like the correlation and the alerting."

More Graylog Enterprise pros

"Splunk has significantly helped with aggregation and correlation of critical logs. Not having to grep on each individual server has made everyone more efficient."

"Splunk Enterprise Security streamlines the creation of what they call notables, which takes a lot of the effort that we would have to put into creating our own solution off the table and does it for us."

"To get visibility from your network devices, servers, and security devices is a great feature."

"It's extremely scalable. It's a very robust solution and certainly has the capability of handling far bigger data requirements than a lot of the other tools. Generally what ends up happening with me is that my clients tend, for the most part, to be mid-tier organizations where the cost of that solutions would be accompanying requirements for people just becomes way too prohibitive. Especially considering the model that they use for costing, which is based on the volume of data. Of course, they're going to put everything including the Coke machine as the ability to collect data off of it, because of course the more they can put through the tool the more money they make."

"If you want to understand how it can analyze or find out incidents, the visibility is good."

"The most valuable features include the incident review and Dashboard Studio."

"The most valuable feature is the ability to look at threats and link them to the MITRE ATT&CK framework."

"One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities."

More Splunk Enterprise Security pros

"Allowed us to help our customers satisfy compliance needs around logging and monitoring."

"The most valuable feature of the solution is the ease of deployment that it provides to users. The integrations that the product has with third-party applications are useful."

"Any unusual behaviour, we can monitor. We have alerts set up to be sent when we receive signs of any unusual behaviour."

"The most valuable feature in AT&T AlienVault USM is the reporting."

"OTX is a great module that lets staff maintain and monitor updates regarding events in the infrastructure and takes decision to improve the security perimeter."

"The most valuable feature is vulnerability management because it gives you insight into your environment to know what systems need to be updated or patched."

"The best feature of this product is the ease of use. It is extremely easy to set up and get going. This is a very useful tool for a small organization."

"The vulnerability manager and the file integration are very good."

More USM Anywhere pros

Cons

"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."

"More customization is always useful."

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."

"The area in Graylog that needs to be improved or enhanced would be the integrations."

"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."

"Graylog can improve the index rotation as it's quite a complex solution."

"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."

"Dashboards, stream alerts and parsing could be improved."

More Graylog Enterprise cons

"The high cost of Splunk Enterprise Security prevented us from using its full capabilities."

"The threat detection system has room for improvement."

"Missing capability for audio/video and image processing."

"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."

"Splunk is not very user-friendly. It has a complex architecture in comparison to other solutions on the market."

"Data retention can be better. If we want to look at the data for five months or six months, that is not available to us. We only have a history of 20 or 30 days. After that, the information gets lost. That is a drawback."

"I'm not as familiar as I should be to answer how Splunk Enterprise Security can be improved, however, one of the improvement points that Enterprise Security could offer is on-prem training."

"I would like Splunk to add more integration. QRadar has many indications with more products than Splunk."

More Splunk Enterprise Security cons

"USM Anywhere relies a lot on the community putting the data in. Often, you'll right-click on the attack, but nothing will be found. That's a weakness of it."

"Plugins could be better utilized, as some of them do not recognize all logs."

"they seem to have bugs from time to time that go unfixed for a while and that is frustrating. I'm not saying the product needs to be bug-free, but they need to be responsive to bugs."

"I want to see more compliance management capability. The quality of integrations seems to be a little bit low."

"We develop additional rules and scripts to make it more usable."

"The solution is a bit complicated. It could be simplified quite a bit."

"It should be able to communicate with other security solutions to stop threats."

"It would be hard for any legitimate MSSP to use it."

More USM Anywhere cons

Pricing and Cost Advice

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."

"Having paid official support is wise for projects."

"Consider Enterprise support if you have atypical needs or setup requirements."

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog."

"I am using a community edition. I have not looked at the enterprise offering from Graylog."

"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."

"I use the free version of Graylog."

"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."

More Graylog Enterprise pricing and cost advice

"Splunk Enterprise Security is an expensive solution."

"It's a little bit expensive for a small to medium enterprise."

"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."

"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."

"The solution is a little expensive."

"I assume that the pricing is reasonable, because if it was too costly, there are other alternatives."

"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."

"I would highly recommend anyone evaluating this option to download the free trial which allows for the ingestion of 500MB of data per day in order to get a feel for what Splunk does at its core. It will get pricey once your ingestion rates start to sky rocket, but I would consider it expensive given the amount of information that it allows you to analyze and react on straight out-of-the-box."

More Splunk Enterprise Security pricing and cost advice

"Its price is in the medium to upper range."

"I don't know exactly, but I know it is based on the number of logs and the retention duration, such as 30 days or something like that. So, the smallest package is about 500 a month for 30 days of logs. There is a virtual machine. You need resources for it. It is a log collecting VM. They provide the software, and you just have to load a virtual machine. So, you're going to incur some CPU RAM and storage for wherever this log collecting appliance is running, which typically is in our cloud and on our platform for the customer."

"Its price is much lower than McAfee ESM."

"It is a product that is priced in a medium range, making it neither a cheap nor a costly product."

"We checked out several competitors. For what it can do and the cost, it was the best option!"

"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."

"It's affordable for most customers."

"It has good pricing."
