Featured Reviews

Ivan Kokalovic - PeerSpot reviewer
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.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.
Kyle Vernham - PeerSpot reviewer
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

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"Real-time UDP/GELF logging and full text-based searching."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"Open source and user friendly."
"I like the correlation and the alerting."
"It is stable."
"The initial setup is straightforward"
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"What I found most useful in ManageEngine EventLog Analyzer is its integration with other ManageEngine applications. It seamlessly integrates throughout the ManageEngine suite, and that's beneficial. I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"The user interface is very good."
"I have made use of technical support and am certainly very satisfied with them."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
"The speed of the search engine"
"I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money."
"I like the ease with which dashboards can be created."
"It has quite extensive support in terms of integration. If you want to do anything, there are tools for that."
"You can integrate Splunk with third-party security automation solutions and set rules for automatic response."
"I like the search feature and the indexing. It's very fast and comprehensive."
"Combating insider threats and advanced persistent threats is an amazing feature of Splunk Enterprise Security, and it gives us the visibility that we need for those detections that other software doesn't have."
"It's the completeness of the solution that we like the most."
 

Cons

"I would like to see some kind of visualization included in Graylog."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"There's a lot to improve in terms of connectivity. Currently, we're utilizing it across various infrastructures and environments, including others' cloud. However, connecting it to our infrastructure and integrating it with some of our SMAX solutions poses difficulties."
"The solution should improve on its log capturing capabilities."
"Support could improve to make the solution better."
"The first tier of customer service and support is not great."
"It may not be as easy to use as Splunk."
"The scalability is limited."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"Certain sections of the developer documentation could use some updating and clarification."
"Sometimes, the data does not match what we're looking for, or the tool contains incorrect data."
". Having a trial version or more training on Splunk would be helpful."
"Its pricing model and integration with third-party services can be improved. We had faced an issue with integration. The alerting feature is currently not available with Splunk, but it is definitely available with Datadog and PagerDuty. They should include this feature. A few dashboards in Splunk look quite old and are not that modern. They aren't bad, but improving these dashboards will definitely make Splunk more attractive and usable. I read in a few blog posts that there were a few security incidents related to Splunk agents. So, it can be made more secure."
"Missing capability for audio/video and image processing."
"The integration feature with other applications, such as anti-DDoS application Arbor, needs to be more powerful."
"We had some connections issues with the solution at the beginning."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."
