Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.

Centralized monitoring has improved threat response but cost control still needs refinement
Based on real operations used in our corporate IT environment, the key features include log correlation and incident view. Microsoft Sentinel's biggest strength is how it correlates multiple related alerts into a single incident. This significantly reduces alert noise and helps the SOC focus on real threats instead of isolated events. Another valuable feature is KQL-based threat hunting with Kusto Query Language. The flexibility of this language allows us to build custom hunting queries based on our environment's behavior. This is extremely useful for detecting low and slow threats or hidden threats that default rules may miss. Cloud-native scalability and stability is another important feature. Being cloud-native, Microsoft Sentinel scales well for medium to large corporate environments without infrastructure management. Stability has been solid in day-to-day production. SOAR automation using playbooks is a feature we highly recommend. Microsoft Sentinel's SOAR functionality helps automate repetitive SOC tasks like alert enrichment and notification. This saves analyst time and improves response consistency.

Quotes from Members

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

Pros

"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
"The in-built SOAR of Sentinel is valuable. Kusto Query Language is also valuable for the ease of writing queries and ease of getting insights from the logs. Schedule-based queries within Sentinel are also valuable. I found these three features most useful for my projects."
"The best feature is that onboarding to the SIM solution is quite easy. If you are using cloud-based solutions, it's just a few clicks to migrate it."
"Being able to dictate and train efficiently and in a streamlined way is probably the most value proposition we have for something in this category."
"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."
"We have seen at least a 60% increase in efficiency with Microsoft Sentinel and the ability to reduce the MTTD down to under five minutes and MTTR down to under fifteen."
"Sentinel enables us to ingest data from our entire ecosystem. In addition to integrating our Cisco ASA Firewall logs, we get our Palo Alto proxy logs and some on-premises data coming from our hardware devices... That is very important and is one way Sentinel is playing a wider role in our environment."
"Microsoft Sentinel's ability to correlate data from multiple sources has improved our capability significantly."
"The UI-based analytics are excellent."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"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."
"The product can be improved by reducing the cost to use AI machine learning."
"In terms of improvements, pricing, licensing, and overall cost could be better."
"Their support can be challenging at times, particularly around unique experiences or circumstances with Microsoft Sentinel."
"Microsoft Sentinel can be improved in terms of automation or connecting with security products so that it is easier to use for general IT admins."
"Sentinel provides decent visibility, but it's sometimes a little cumbersome to get to the information I want because there is so much information. I would also like to see more seamless integration between Sentinel and third-party security products."
"The costs and pricing of Microsoft Sentinel are expensive. That's my biggest complaint, especially from customers who are concerned about the significant expense."
"The built-in SOAR is not really good out-of-the-box. The SOAR relies on logic apps and you almost need to have some kind of developer background to be able to make these logic apps. Most security people cannot develop anything..."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"From a cost perspective, there are some additional charges in addition to the licensing."
"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."
"There are no additional costs other than the initial costs of Sentinel."
"Sentinel is fairly priced and pretty cost-effective."
"The pricing isn't very high. It depends on the number of logs you have. If you're expecting to ingest 50 to 60G in a day, but you're only ingesting 20 to 25G per day at first and you have a good team to analyze the logs, then you can segregate the ingestion at under 15G."
"The price is reasonable because Sentinel includes features like user behavior analytics and SOAR that are typically sold separately. Overall, a standalone on-prem solution would require some high-end servers, and there's a different cost. It is a cloud-based solution, so there are backend cloud computing costs, but they are negligible."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"We only pay for the amount of data we bring in, which is fair."
