User Testimonials

Likelihood to Recommend
If you already have a basic understanding of Elasticsearch and/or MongoDB, Graylog will be a great fit when it comes to log aggregation. It will be a decent option even if you don't have any experience but have the time and willingness to roll up your sleeves that learning those tools will require. Graylog supports plugins to extend functionality for things like SNMP traps, telemetry collection, and solar flares. As is the case with most software with plugins, if the core functionality for which you are looking (i.e. not logging) is based on a plugin, Graylog probably isn't for you. The majority of the plugins in the marketplace are developed by third-parties looking to solve their specific use case so bug fixes and new features are not a given.

Well-Suited Scenarios:
Real-Time Threat Response: ES excels in swiftly detecting and responding to security threats through data correlation.
Compliance Management: ES streamlines compliance with detailed logs and reports, ideal for regulated industries.
User Behavior Analytics: Effective in monitoring user and entity behavior, particularly for insider threat detection.
Large-Scale Environments: Valuable for organizations with diverse data sources and high volumes of data.
Incident Investigation: ES aids in post-incident analysis, reconstructing events to understand root causes.
Less Appropriate Scenarios:
Smaller Organizations: For simpler setups, ES may be complex and costly.
Static Environments: In low-risk settings, ES's advanced features may be unnecessary.
Limited Resources: Tight budgets or sparse IT resources may hinder effective ES use.
Lack of In-House Expertise: Without security experts, optimizing ES can be challenging.
Budget Constraints: ES may be cost-prohibitive for budget-conscious organizations, prompting consideration of more affordable alternatives.

Pros
  • The free edition is extraordinarily powerful.
  • Log searching is quick.
  • The web interface is sleek, and the install is relatively quick.

  • Its best feature is its user interface, which is easy to navigate and understand. All you need is a little tutorial on how to use the Splunk query language and you're done.
  • Logs can be easily uploaded or shared across multiple platforms and display a highly insightful graphical representations of data using graphs, tables, and many other formats.

Cons
  • The graphs and visualizations are limited on the dashboard if there were more options it would be better for different kinds of data.

  • To identify User Behaviour analysis is lacking component which we get in Splunk UBA.
  • The documentation part is hard to work on because if the new user tries to learn ES then the documentation is not user-friendly.
  • ES must ass more Knowledge objects by default to make security-related aspects more reliable and enhance the details.

We are very happy with Splunk and would advise anyone to take a serious look at it. It might look pricey but the rewards Splunk offers seem endless.

Usability

You definitely need to learn how to use Splunk to get the most of the tool. There are many courses available for free to get up to speed on the usability of the tool but it's not that simple. It will take time to digest all the data and to understand how to query for what you are looking for.

I'm not an ES user, but, in my implementation I usually try to prevent all service stops to guarantee High availability to the final customers.

Performance

ES requires a very performant infrastructure: if it has it's performant, otherwise not. I had situation with a very performant infrastructure and I didn't notized that it was a distributed architecture, it seemed that there ware few data on my PC, othewise I experienced less performant infrastructures with less performaces.

From a product perspective, it's an 8.
I am still unhappy with the pricing model for the enterprise. Graylog competes against the likes of IBM and Splunk, but your still the new kid on the block. To price Graylog enterprise at 50k for 20GB ingest an unrealistic data. It would require multiple facets of Graylog to be stood up and only forward pruned logs to the paid version.

It's good when it's responsive, but I've had times where I had to wait quite a while for a response. But these are typically the exceptions rather than the rule. When you do get a response it is always well-informed and appropriate. I would say they've been trending better over time with this.

I experienced only on-line training, but the trainers were very professional and competent. Maybe it could be more useful if they also have an experience in projects because sometimes they didn't have a real project experience to communicate to the students. Anyway, it was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself, aven if I have more than 10 years of Splunk activity experience.

It was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself. The only problem was that, when I worked with the Splunk Professional Services, I found some difference between the training contents and the information from PS. In addition is required a long experience on Splunk Enterprise for the data ingestion part, in other words I'm able to work with ES because I'm worling on Splunk since 11 years, otherwise I'd some problem.

It's a fantatic product and it was very useful the presence of Splunk Professional Services for the Design Phase and the final Health Check.

Alternatives Considered
Azure Monitor is not exactly what I mean, but I couldn't find Azure Application Insights. Anyway, for a large organization, Azure makes more sense than using Graylog because a lot of logging will already be inside Azure. And you don't want to have two "central" logging locations. But Azure is chaos and highly "not intuitive." So for small and mid-size organizations, Graylog is still the better option.

LogRhythm is good for a team comprising mostly non-technical IT users. Unlike Splunk, it has a GUI log search and a good ticketing system. Splunk is better than Logrhythm for me as it provides me with the ultimate flexibility to write custom queries. Scalyr is a good tool and quite frankly lot faster than Splunk. However, I prefer Splunk because of its better Dashboards and panel customization abilities. Elastic is another amazing tool. It is hard to choose between the two especially because both have different sets of logs on them. I use both. Elastic for internal server logs, Splunk for everything else.
