Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The product can integrate with any device.""The pricing of the product is excellent.""You can fine-tune the SOAR and you'll be charged only when your playbooks are triggered. That is the beauty of the solution because the SOAR is the costliest component in the market today... but with Sentinel it is upside-down: the SOAR is the lowest-hanging fruit. It's the least costly and it delivers more value to the customer.""The log query feature has been the most valuable because it's very good. You can put your data on the cloud and run queues from Sentinel. It will do it all very fast. I love that I don't have to upload it to an Excel file and then manually look for a piece of information. Sentinel is much faster and is good for big databases.""The SOAR playbooks are Sentinel's most valuable feature. It gives you a unified toolset for detecting, investigating, and responding to incidents. That's what clearly differentiates Sentinels from its competitors. It's cloud-native, offering end-to-end coverage with more than 120 connectors. All types of data logs can be poured into the system so analysis can happen. That end-to-end visibility gives it the advantage.""Microsoft Sentinel comes preloaded with templates for teaching and analytics rules.""The dashboard that allows me to view all the incidents is the most valuable feature.""It has a lot of great features."

More Microsoft Sentinel Pros →

"It makes maintenance very easy.""The real-time analysis adds value.""It gives better overall visibility. Before, we didn't have a unified system for managing security alerts. ArcSight introduced various alerts, giving us a better visibility of potential problems.""The stability of ArcSight Enterprise Security Manager is good.""Stable solution with good customer service support.""The product is quite mature. It's been around for a long time.""The feature that I have found the most useful is that it can be deployed to the cloud.""The most valuable feature of ArcSight ESM is its ease of use."

More ArcSight Enterprise Security Manager (ESM) Pros →

"The initial setup is simple, not very complex. Initial deployment takes around 10 to 15 minutes to set up the entire base for Splunk including all three tiers.""Its integration is most valuable. Its UI is also pretty much easy.""We are much faster finding and addressing issues with Splunk.""The dashboard and reporting are very good... It provides very good visibility in a hybrid cloud environment, and you can build custom utilization APIs using Splunk.""Easy to deploy and simple to use.""Out-of-the-box, it seems very powerful.""It is very simple to tweak or write a small piece of glue code to go ahead and create a new dashboard for a business unit to make near real-time decisions to focus more on other geographies when launching the product.""The client site login is pretty extensible and probably cost-effective."

More Splunk Enterprise Security Pros →

Cons
"They're giving us the queries so we can plug them right into Sentinel. They need to have a streamlined process for updating them in the tool and knowing when things are updated and knowing when there are new detections available from Microsoft.""We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed.""If I see an alert and I want to drill down and get more details about the alert, it's not just one click. In other SIEM tools, you just have to click the IP address of the entity and they give you the complete picture. In Sentinel, you have to write queries or use saved queries to get details.""Some of the data connectors are outdated, at least the ones that utilize Linux machines for log forwarding. I believe that Microsoft is already working on improving this.""The reporting could be more structured.""They could use some kind of workbook. There is some limitation doing the editing and creating the workbook.""The following would be a challenge for any product in the market, but we have some in-house apps in our environment... our apps were built with different parameters and the APIs for them are not present in Sentinel. We are working with Microsoft to build those custom APIs that we require. That is currently in progress.""I would like to see more AI used in processes."

More Microsoft Sentinel Cons →

"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery.""The UI interface is somewhat complex and needs to be simplified.""Micro Focus does not have a physical presence here in Pakistan, although IBM does.""I am having issues with report generation with older versions. I don't know if this is because of compatibility issues, but report generation has been a little bit difficult in older versions. It is not similar to the newer and current versions. We are looking at moving to the cloud. It would be good if ArcSight ESM can move to the cloud. They already seem to be working on this. It would also be very helpful and great if we can integrate external threat intelligence, machine learning, and AI into this solution. It has good dashboards, but they can always be better. Its stability can also be improved.""The dashboard looks a bit cumbersome.""​In certain cases, this product does have false positives, which the company should work on.""The correlation engine effectively connects different events, significantly improving our detection reach. However, limitations exist with non-default alerts, where additional costs arise for integration.""What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature. That feature should be more powerful and have more correlation in terms of AI/ML, though MicroFocus has done a good job in adding analytics to ArcSight Enterprise Security Manager (ESM) which has become a big draw to customers. What I'd like to see in the next release of the solution is the addition of AI/ML features."

More ArcSight Enterprise Security Manager (ESM) Cons →

"​Not even Splunk's support guy, who came to our firm, could help with defining proper role management.​""Search head clustering is often temperamental in its current state and should be improved, replaced by something better, or be reverted to search head pooling.""Its setup is a little bit complex for a distributed environment. Their support can also be better. If we miss the response for more than a week, they usually close the case. Sometimes, it can take us more than a week to reply.""One issue is that we are getting a lot of false positives. We are trying to reduce them by customizing the default rules, changing thresholds, and using white-listing and black-listing. It's getting better and better as a result. But they need to build components that would reduce the false positives.""It could be more user friendly, in terms of the end-user experience.""Certain sections of the developer documentation could use some updating and clarification.""The tool itself is very difficult to configure. It's great for its number of inputs, for the different types of systems devices, and things that it could collect information from. To actually make good use of it, you need a fairly dedicated team of people that have some reasonably good programming or modeling skills to be able to do the things that you need to do with it. Whereas a lot of the other tools are better packaged for that, and so require a lot less training and a lot less dedication.""Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."

Pricing and Cost Advice
  • "It comes with a Microsoft subscription which the customer has, so they don't have to invest somewhere else."
  • "It is a consumption-based license model. bands at 100, 200, 400 GB per day etc. Azure Sentinel Pricing | Microsoft Azure"
  • "Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
  • "I have had mixed feedback. At one point, I heard a client say that it sometimes seems more expensive. Most of the clients are on Office 365 or M365, and they are forced to take Azure SIEM because of the integration."
  • "It is kind of like a sliding scale. There are different tiers of pricing that go from $100 per day up to $3,500 per day. So, it just kind of depends on how much data is being stored. There can be additional costs to the standard license other than the additional data. It just kind of depends on what other services you're spinning up in Azure, or if you're using something like Azure log analytics."
  • "I am just paying for the log space with Azure Sentinel. It costs us about $2,000 a month. Most of the logs are free. We are only paying money for Azure Firewall logs because email logs or Azure AD logs are free to use for us."
  • "Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
  • "Azure Sentinel is very costly, or at least it appears to be very costly. The costs vary based on your ingestion and your retention charges."
  • More Microsoft Sentinel Pricing and Cost Advice →

  • "HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
  • "ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
  • "Aggregation can help a lot in pushing down licensing costs."
  • "​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.​"
  • "Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
  • "Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
  • "The pricing is great compared to others."
  • "The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
  • More ArcSight Enterprise Security Manager (ESM) Pricing and Cost Advice →

  • "Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
  • "Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
  • "It is not cheap."
  • "Splunk Enterprise becomes extremely expensive after the 20GB/month license."
  • "You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
  • "Splunk licensing model might seem expensive but with all the gain in functionalities you will have compared to traditional SIEM solutions I think it’s worth the price."
  • "Pricing is pretty fair."
  • "While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
