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."
"It is quite efficient. It helps our clients in identifying their security issues and respond quickly. Our clients want to automate incident response and all those things."
"The integration between them is good and straightforward, the documentation is excellent, and we do not have any problems."
"The most valuable features are its threat handling and detection. It's a powerful tool because it's based on machine learning and on the behavior of malware."
"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."
"Azure Sentinel works perfectly in this case because we are using Microsoft resources."
"Microsoft Sentinel is an awesome SIEM/SOAR tool for customers with active Cloud presence."
"A lot of the automation inside Sentinel comes with inside actually rolling out brand new Sentinel environments. We utilize that a lot and it might go beyond just Sentinel, for example, utilizing templates in Azure and templates elsewhere to actually deploy out."
"The part that was very unexpected was Sentinel's ability to integrate with Azure Lighthouse, which, as a managed services solution provider, gives us the ability to also manage our customers' Sentinel environments or Sentinel workspaces. It is a big plus for us. With its integration with Lighthouse, we get the ability to monitor multiple workspaces from one portal. A lot of the Microsoft Sentinel workbooks already integrate with that capability, and we save countless amounts of money by simply being able to almost immediately realize multitenant capabilities. That alone is a big plus for us."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"The integration challenges arise from both sides; Google tends to be noisy, and we find only ten analytic rules out of the box, necessitating the use of Defender for Cloud for alerts, which indicates a need for better documentation during deployment."
"The interface could be more user-friendly. It''s a small improvement that they could make if they wanted to."
"I can't think of anything other than just getting the name out there. I think a lot of customers don't fully understand the full capabilities of Azure Sentinel yet. It is kind of like when they're first starting to use Azure, it might not be something they first think about. So, they should just kind of get to the point where it is more widely used."
"Improvement-wise, I would like to see more integration with third-party solutions or old-school antivirus products that have some kind of logging capability. I wouldn't mind having that exposed within Sentinel. We do have situations where certain companies have bought licensing or have made an investment in a product, and that product will be there for the next two or three years. To be able to view information from those legacy products would be great. We can then better leverage the Sentinel solution and its capabilities."
"Professional support is not that great. Often, I'd rather not involve them."
"We'd like to see more connectors."
"There is room for improvement in entity behavior and the integration site."
"It could have a better API to be able to automate many things more extensively and get more extensive data and more expensive deployment possibilities. It can gain some points on the automation part and the integration part. The API is very limited, and I would like to see it extended a bit more."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"I'm not happy with the pricing on the integration with Defender for Endpoint. Defender for Endpoint is log-rich. There is a lot of information coming through, and it is needed information. The price point at which you ingest those logs has made a lot of my customers make the decision to leave that within the Defender stack."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"From a cost perspective, Microsoft Sentinel is quite costly."
"Sentinel is expensive relative to other products of the class, so it often isn't affordable for small-scale businesses. However, considering the solution has more extensive capabilities than others, the price is not so high. Pricing is based on GBs of ingested daily data, either by a pay-as-you-go or subscription model."
"Pricing is pay-as-you-go with Sentinel, which is good because it all depends on the number of users and the number of devices to which you connect."
"Microsoft Sentinel is expensive."
"I don't know yet because they gave us a 30-day test window for free."
"Currently, given our use case, the cost of Sentinel is justified, but it is expensive."
