Featured Reviews

Merit Ronald - PeerSpot reviewer
Senior Software Engineer at Absa Bank Uganda
Centralized log insights have reduced investigation time and improve security response
One improvement I want to see in Graylog Enterprise is artificial intelligence to help us automatically identify unusual patterns and suggest possible causes. I also want to see more ready-made dashboards and alert templates for common security use cases to help us gain value from the platform faster after deployment. Lastly, I want to see improvements in handling very large volumes of data, especially after searching, and a more user-friendly log management system, particularly in large environments. I give Graylog Enterprise a 9 out of 10 because it has a limitation of a steep learning curve for new users due to the many configuration options. It takes considerable time to become comfortable with creating searches, dashboards, and alerts. Additionally, in very large environments with large volumes of logs, it requires careful planning, and its data retention is quite limited.

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.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"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."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The solution's most valuable feature is its new interface."
"I am very proud of how very stable the solution is."
"The ability to write custom alerts is key to information security and compliance."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"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 have made use of technical support and am certainly very satisfied with them."
"ManageEngine EventLog Analyzer was a lower-cost alternative, and it was easier to install and manage."
"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, and I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"We use the solution because it is granular."
"The initial setup is straightforward"
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"The support system is very good."
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"Splunk has facilitated the correlation of information security logs to look for incidents which could cause damage to the company's infrastructure, as well as financial losses from leaks."
"The most valuable function is the notable events. When I joined the team, I asked them what they could currently see, and they said nothing. I was pretty shocked. I know for a fact that they're using Enterprise Security or at least they had purchased it. I told them that there are several dashboards within Splunk that we can leverage. There is also notable events where we can see potential incidents or potential alerts about the infrastructure and the network itself."
"The correlation searches (properly configured) populate the Incident Management dashboard and provide me a quick birds-eye view of my most important concerns."
"The biggest advantage I can see in Splunk Enterprise Security is the big data analytics."
"The product is generally stable and forgiving."
"Splunk Enterprise Security is a huge value-add to us because I can confirm that our security team treats it as a normal component of their daily operations."
"The risk-based alerting (RBA) is one of the valuable features."
"The ability to view all of these different logs, then drilling down into specific times or into specific data sources, has proved to be the greatest aspect in decreasing our troubleshooting overhead time."
 

Cons

"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 biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"The alerting system could be more flexible."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"Lacks sufficient documentation."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"I would like to see more detailed reports."
"The scalability is limited."
"The solution should improve on its log capturing capabilities, the authentication, when a person logs onto a network device."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"The product does not have certain advantages, especially the correlation tools. It was not working as per our expectations."
"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."
"We haven't saved any money with Splunk Enterprise Security. Instead, we have spent excess of the budget on this with unexpected costs."
"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."
"Code understanding requirement is complicated for most users."
"I do not have any pain points for Splunk Enterprise Security. I am still trying to learn it, but there can be more information on the education side for Splunk Enterprise Security. It would be nice if the certification path was more specific to what I use instead of being so broad."
"Splunk Enterprise Security can provide more details and help CISOs resolve vulnerability situations better. The reason is that the tools we choose for data analysis and log collection cannot collect all the data and logs. Splunk Enterprise Security should help me with this, but it cannot."
"It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
"It is very complicated to write your own correlation rules without the help of Splunk support."
 

Pricing and Cost Advice

"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"Having paid official support is wise for projects."
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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."
"We are using the free version of the product. However, the paid version is expensive."
"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."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"There is a yearly subscription for the solution."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"Further reductions would be fantastic, and I believe that more and more people would flock to it."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"Splunk is definitely not a cheap solution. It is an expensive product."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"Luckily, we come under a large federal agency, and before the pandemic, they signed a large enterprise license agreement. It worked out great and to our advantage because we are a small organization. We got a 300 gig license, and we just did not have the buying power to be able to get products cheaply. Because we all partnered together under the agency umbrella, we were able to get Splunk Enterprise Security, UBA, and ITSI for cheap. This was good considering the fact that some of these premium apps require a minimum number of users, and we do not have the number of people needed to even justify buying it."
"It is quite expensive."
"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."
