Cost and vegetative growth in the medium/long term. It is a great tool but you have to be careful in storing a lot of data (without any criteria). Use it as an "smart-data/small-data repository", not as a "raw centralizer, stage-area or pure-SIEM". The quantity of "use-case" is not so big when compared with others tools (and for example, you dont have specific use-cases divided by industry-segments". Before choose any tool and define your BOC (Business Operation Center), read about datamart/datawarehouse concepts and models (design and archicture too) defended by Inmon & Kimball. You'll saving a lot of $ in future.

If it is a complex environment and data ingestion is huge where you want to ingest Syslogs or networking devices logs, you should go with Splunk. It is better than QRadar. Nowadays, the usage of AWS is growing, and that should be taken into consideration when deciding about on-premises or cloud deployment. I would rate it a nine out of 10. I find it great. I'm very eager to do the Splunk certifications as well.

My understanding is that as a company, we are migrating to Azure. When this happens, Splunk will be decommissioned. Overall, I don't think that this is a very good product and I don't recommend it. I would rate this solution a five out of ten.

There is a large number of options for training and certification. The more training you have the more useful Splunk becomes. However, right out the gate you can do useful searches due to the search bar design.

I would rate this solution a seven out of ten. Splunk has a user-friendly interface and GUI. Its architecture is also much more sophisticated than others.

reviewer1086690 - PeerSpot reviewer

It is hard to integrate because it can do so many things. A lot of people think it is a set-it-and-forget-it solution, but it is a full-time job for somebody. I would advise others to plan and prepare for ongoing management. It requires a dedicated person for management. Compared to other SIEMs, it is a 10 out of 10.

Chris Danshaw - PeerSpot reviewer

I would advise making sure that you incorporate enough storage and processing in order to properly support the environment. I would rate it an eight out of 10. It is definitely the best tool I've ever used, but nothing is perfect. They could do a little bit better on data compression and system resource management, but outside of that, it is an excellent product.

We use Splunk and we also sell and support it for our clients. Normally our policy is to keep software updated to the latest version. The main issue is that we do enterprise architecture and network and security operations. We recommend certain platforms to clients. We don't always sell Splunk directly to them due to the fact that, since we're being hired to help them make choices, we need to be neutral. In the cases where it doesn't make sense, we don't sell it. We just help clients make decisions. I don't know which version of the solution we're using. I'm an architect; I'm not on the operations level. I'm not the one who actually uses it. Our operations use it. I get dashboard results and I do reports that are based on it, however, I'm not the one actually running it. We have a NOC and a SOC and others use it a lot more individually. They have a lot more interaction than I do. I'm getting reports out of it. Others are actually connecting to it, using it as a tool. I'm not a tool user. I'm an information user. All Splunk is, is data collection and it can sort things out on a dashboard. However, a lot of what Splunk does is collect data and you have to decide what kind of information you're going to let it collect. When we're doing design operations we have to really pay attention to what we're doing, so we don't actually slow things down or impede things. The reason we use Splunk is we put a lot of data into it. With Splunk, you need to really be careful about what you're monitoring and how you use it, to get keep the results working. It's a good tool if you know what you're doing and what you need to be logging. You need to be aware of what you're logging to ensure it isn't going to cause problems with your performance. I wouldn't recommend it for somebody who's coming in new. Of the clients we have using it, I don't know if any of them don't have professional IT running it. It's important to really understand what's going on. I'd rate the solution at an eight out of ten. In certain environments, it could be a bit complex. It's not something you could just drop into an organization, you need to be trained to use it. You need the experience to use it properly.

We are partners of Splunk and provide the solution to customers. I feel Splunk is easy to utilize. My company has an app. on which the solution is deployed on-premises on a single server. There is another team in my company that works with Splunk products. I rate Splunk as a seven-point-five out of ten.

We're a partner and a customer. I'm using the latest version of the solution. I would highly recommend the solution. It's the best product out there. It's definitely easy to set up. The use cases are multiple. It's not restrictive in terms of the efficiency of the platform. Just make sure that you have enough resources or good counsel from people who can help with the use cases. If you do the sky would be the limit. It is a good solution. I'd rate the solution at a ten out of ten.

When using this solution for Security Information Management(SIM), I highly recommend importing data sources from the whole cycle for the service security chain. Some people only use main inputs and not all of the data sources they have. They might not have some data sources, in this case, you can purchase one or there are free open-source ones available. You will then have this data source that can enrich your life because many correlations are done with this data. I rate Splunk an eight out of ten.

We are resellers. We use a variety of deployment models, including private cloud and hybrid. This solution is the best security solution. If a company is looking for the best, they have to buy Splunk. It is a very good and very mature solution. It is very easy to integrate with some other service or security solutions. If they have specific solutions that need to be integrated for monitoring purposes, it should be a problem. For example, it integrates very well with Cisco. I'd rate the solution at a ten out of ten. We are quite happy with its capabilities.

It is important to define different guidelines to integrate Splunk in development, QA, and production deployments. Additionally, define the applications that will be used and the configuration of the databases to collect the data. If this is not done, there will be a lot of issues due to, for example, master access or permissions to use the database collector and blocks.

We use a mixture of public and private cloud deployments. I would definitely recommend the solution, having seen it work for others so well. Its ease of usage and its man integrations make it a great product. The way you can access whatever you need on the solution is very similar to a Google bar where you can search for anything you need. It's just a super quick responsive, product. Overall, I would rate it a perfect ten out of ten. We have no complaints.

It's important to prepare. You can't just get a solution and start to implement it. A big part of that needs to be preparation, and in IT, we're not great at that. I would go with Elastic, a similar product but better. The licensing is a little different but it gives you a little more freedom to do things. It's really flexible with what you can do and versatile in how you can use it. Splunk is still top when it comes to log collection. If you wanted anything more than that, you should probably look into using several different products. There isn't really one product that you're going to find that's going to give you that coverage and I just like the versatility of using several different products. There are some other things you can use that actually do a better job at the correlation part. I would rate this solution a seven out of 10.

Julio Ortiz - PeerSpot reviewer

I would recommend Splunk to any company: small, medium, and large. Splunk is a great tool but you should get a partner who knows what they are doing, implementation-wise. On a scale from one to ten, I would give Splunk a rating of nine.

I would definitely recommend using Splunk. They have free learning models available. There are models available on their learning page where you can gain a better understanding of how to use Splunk. Within one month alone, you can at least understand how to operate Splunk, whereas, with other tools, it can take a lot of time to understand. On a scale from one to ten, I would give Splunk a rating of nine. The only downside is the cost. Price is the only factor; sometimes, companies shy away from Splunk because of the price.

We're just a customer. We don't have a business relationship with Splunk. We're using the latest version of the solution. I'd advise those considering the solution to do some basic training before jumping into using the solution. It will help you understand how everything is supposed to work. I'd rate the solution at an eight out of ten, due to the fact that it's more flexible than other solutions. I like the idea of taking a log, any log, and putting it into a tool and creating your events and your conditions in order to get the output that you're looking for. It's more scalable and flexible than other options on the market.

HimanshuTejwani - PeerSpot reviewer

If you're going with this solution, make sure that when implementing the ports are open. If they're not open, it creates problems with the server. Other than that, this is a very stable and very easy to configure product. We can easily deploy and easily use. Other similar solutions are difficult to configure, Splunk is the simplest. I've used three or four monitoring tools and Splunk is the easiest. If a company can afford it, this is a good product. We are planning to shift to another product because of the cost. We're searching for an open source or cheaper product. I would rate this solution a nine out of 10. They lose one point for the price and lack of infrastructure support.

We're just users. We don't have a business relationship with Splunk. We're on a variation of version seven. I'm not sure of the exact one. It's not quite the latest. I'd advise new users, if they have the budget for it, to go and take the training that they offer. Or, for casual users, you just want to spend as much time watching YouTube videos as you can. It will help lessen the learning curve. As a solution, it's still pretty much industry standard. I would give it a nine out of ten overall, even though I have my gripes with it.

Praful Bhatnagar - PeerSpot reviewer

Splunk is a good product but I would definitely tell people to analyze their requirements to see if Splunk fits their use case, or not. The licensing model is very complicated, so if there is a product that has a better licensing model then it would probably be good to start with that. Then, later on, if the product is not working well enough, then they can switch to Splunk. At that point, they will have knowledge of the data they are using and will understand the costs that they might incur while using it. The only way that I would suggest somebody use this as their first solution is if they already had all of the data that is required to get a cost estimate. I would rate this solution a seven out of ten.

Balamurali Vellalath - PeerSpot reviewer

We're partners. We have a business relationship with Splunk. We're using the latest version of the solution. Overall, I would rate the solution at a seven out of ten. I'd advise potential new users to ensure they do proper sizing before deploying the product. If it's a very large deployment, the number of endpoints will be quite sizeable. You need to figure out the correct number of endpoints as well as endpoint devices, switches, routers, etc. It's also a good idea to look at use cases. Splunk is very strong in some use cases. It's important to look into deployment scenarios and check out the use cases before deploying anything. My biggest takeaway after working with the solution is that the environment is very important. You need to be clear about the problem you are addressing and it takes a lot of planning at the outset.

Praful Bhatnagar - PeerSpot reviewer
Top 5Real User

I would definitely suggest sending people to analyze or evaluate Splunk. Because the licensing model is very complicated to understand, it would be better to start with another product that provides a better licensing model. Later, if the product is not working well, they can consider using Splunk and may have a better understanding of the cost. For me, I would not recommend Splunk as their first solution unless they have all of the data that is required. I would rate Splunk a seven out of ten.

Gavan McLaughlin - PeerSpot reviewer

It works well when searching logs. If you looked to try to do things beyond this, the problem that we ran into is that we treated it as the hammer which hits all nails. That is not really feasible, and there are other tools out there that can do more specialized things. User administration is key. Trying to prevent users from being able search records all the time is a huge problem. You need a tight approval process on dashboards, making sure the dashboards are queried in the most efficient way possible. The on-premise version that we had was not scalable at all. It was very difficult to use. We have EC2 instances in the cloud with Splunk installed, which is more scalable and easier to use. It now works much better.

Tomi Juslin - PeerSpot reviewer

Splunk's website is quite useful. You can find a lot of information on it. I would recommend to use it and try to figure out the product's features and what you can actually do with Splunk. You can do a lot of things with Splunk, but you need to know what to do first. I have used both the AWS and on-premise versions, but in two different environment, so I am unable to compare the versions.

Engineercb47 - PeerSpot reviewer

Make sure it fits your use case. Be clear about what you want to achieve, get out of the product, and how you want to integrate it. Once you tie the solution into your systems, it is not trivial or easy to walk away from. Therefore, due diligence needs to be made to understand what your requirements are before choosing a product. Some companies may not even want to host, and prefer to go the managed services route. We have it integrated with every product that I can think of. We use both the AWS and on-premise versions. The AWS hosted version typically caters to all the microservices that we run on AWS, so there is a clear segregation between on-premise and cloud. In terms of usability and experience, both of them have been similar. We have seen a few bottlenecks on the cloud, but that can probably be attributed more on the user side of the house in terms of the way we write our applications and the type of payloads that we sent this month. This is an optimization which is ongoing from our end. Other that, we have been fairly happy with Splunk and what we get out of it.

it_user762567 - PeerSpot reviewer

As a logging solution, I would say it's probably an eight or nine. If you're talking about the SIEM I'd say it's probably about a five. For logging, I think they would have to change the costing model. The costing model is way out of line. It's built for very large organizations.

Shaveta Datta - PeerSpot reviewer

I would rate this solution a nine out of ten. I rated it a nine because every tool will have its drawbacks but ultimately it's a very good tool in comparison to HP ArcSight. If we can add on a scalability feature it would significantly improve the solution. I would advise someone considering this solution to use it at least for a year to get a hands-on and technical understanding because it's a good product. Then decide whether or not to move forward with Splunk - but I would advise to stick with Splunk.

Go with Splunk. A lot of people know how to use it because they have experience with it. It works well. While it has some pain points, it provides reports and data visibility. It integrates great with Opsgenie, PagerDuty and Slack. We love the Slack integration, as works great with the Slack alerts. We use the on-premise version in our data centers and we use the AWS version. We are just starting to migrate to the AWS hosted version, and I have not seen a difference.

Enterpri4059 - PeerSpot reviewer

Build your environment a lot bigger than you think you will need it, because you fill it up quickly. We log somewhere in the neighborhood of two to four terabytes a day per data center. We use both AWS and SaaS versions. With the SaaS version, you don't have as much control, but it functions the same, so there is no real difference. Though, the AWS version is probably easier to scale, because it is AWS.
