"Sentinel pricing is good"
"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"The product can integrate with any device."
"The Log analytics are useful."
"The standout feature of Sentinel is that, because it's cloud-based and because it's from Microsoft, it integrates really well with all the other Microsoft products. It's really simple to set up and get going."
"It is able to connect to an ever-growing number of platforms and systems within the Microsoft ecosystem, such as Azure Active Directory and Microsoft 365 or Office 365, as well as to external services and systems that can be brought in and managed. We can manage on-premises infrastructure. We can manage not just the things that are running in Azure in the public cloud, but through Azure Arc and the hybrid capabilities, we can monitor on-premises servers and endpoints. We can monitor VMware infrastructure, for instance, running as part of a hybrid environment."
"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 provides the capability to integrate different log sources. On top of having several data connectors in place, you can also do integration with a threat intelligence platform to enhance and enrich the data that's available. You can collect as many logs and build all the use cases."
"I really like the correlation part and the way the logs are correlated. I have never faced issues with parsing in this product. I like the way it parses, and everything is so clear to me."
"ArcSight Enterprise Security Manager (ESM) works perfectly. It's a stable and scalable product."
"I value the event correlation of this product."
"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."
"Usability is the most valuable feature. The accessibility is quite good."
"We do consulting and I get feedback from our clients that the product really helped them with compliance, especially with GDPR."
"The real-time analysis adds value."
"The solution has gone beyond signature-based monitoring and analysis and is AI-powered. It is good enough to cover the full range of cybersecurity services."
"Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules."
"Splunk Enterprise Security is a standard solution providing good customer service and partnership."
"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 most valuable features in Splunk are the search function and the ability to run selected session reports. The session reports are important because I can use them to see what is going on in our environment weekly. Additionally, we can use the graph to see how often that particular event is happening."
"It has helped us look at modern technology, as well as penetrate our legacy systems, to see where the bottlenecks are."
"The most valuable feature of Splunk Enterprise Security is website activity monitoring."
"The graph visualization is the most valuable feature."
"It has the ability to correlate data, analyze and review it."
"The solution should allow for a streamlined CI/CD procedure."
"The data connectors for third-party tools could be improved, as some aren't available in Sentinel. They need to be available in the data connector panel."
"Only one thing is missing: NDR is not available out-of-the-box. The competitive cloud-native SIEM providers have the NDR component. Currently, Sentinel needs NDR to be powered from either Corelight or some other NDR provider."
"Sometimes, it is hard for us to estimate the costs of Microsoft Sentinel."
"Azure Sentinel will be directly competing with tools such as Splunk or Qradar. These are very established kinds of a product that have been around for the last seven, eight years or more."
"They could use some kind of workbook. There is some limitation doing the editing and creating the workbook."
"If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."
"Sentinel still has some anomalies. For example, sometimes when we write a query for log analysis with KQL, it doesn't give us the data in a proper way... Also, the fields or columns could be improved. Sometimes, it is not giving the desired results and there is a blank field."
"The onboarding process for this solution could be better. It also needs a better GUI."
"ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them."
"When I asked our networking juniors for a comparison between LogRhythm and ArcSight, they said that both platforms are almost the same. It is just that LogRhythm is more modern with a digital platform, which probably gives it some advantage over ArcSight. ArcSight is a very old and mature product that is running on an old platform. It is an old legacy platform. In terms of new features, it just requires platform upgrades so that it becomes lighter and easily adaptable, specifically in the cloud. It would be a good thing if they can also make reporting easier."
"The visualization is not very good compared to Splunk."
"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 stability isn't quite perfect. We occasionally run into problems."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"Could benefit from a more modern interface."
"Splunk could add more ways to manage archiving and storage. There isn't a web interface. You can do this on the SaaS version, but the on-premise platform doesn't have this option. It has other things but no option for remote NAS. I would like to have a personal web interface where I can specify how long logs should be stored. To have this readily available on the web, you need to adjust some settings on the backend. That is tricky."
"Their technical support sucks."
"Our two main complaints are about the difficulty of the initial setup and the licensing model."
"It will be helpful for customers if they can create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers."
"It needs integration with a configuration management solution."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
"The integration could be a bit better. They charge for certain integrations."
"It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
