Tony Zafiropoulos - PeerSpot reviewer
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.
Ivan Angelov - PeerSpot reviewer
Threat detection and response capabilities enhance investigation processes
My security team has been using Microsoft Sentinel for around two years. We also have Bastion and SolarWinds as part of our monitoring tools. We use a three-way tool, alongside Microsoft Sentinel, in our environment The most valuable features for us include threat collection, threat detection,…

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."
"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."
"Microsoft Sentinel enables you to ingest data from the entire ecosystem and that connection of data helps you to monitor critical resources and to know what's happening in the environment."
"Microsoft Sentinel is cloud native, which is a significant advantage. The data connectors that provide the ability to connect third-party log sources are highly valuable."
"Log aggregation and data connectors are the most valuable features."
"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 automation feature is valuable."
"Microsoft Sentinel has helped by streamlining our security. We have a nine-member network team, with three members managing security for the city, and Sentinel allows us to operate an unofficial SOC."
"It has basic out-of-the-box integrations with multiple log sources."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Sometimes, we are observing large ingestion delays. We expect logs within 5 minutes, but it takes about 10 to 15 minutes."
"We've seen delays in getting the logs from third-party solutions and sometimes Microsoft products as well. It would be helpful if Microsoft created a list of the delays. That would make things more transparent for customers."
"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."
"In terms of improvements, pricing, licensing, and overall cost could be better."
"We have been working with multiple customers, and every time we onboard a customer, we are missing an essential feature that surprisingly doesn't exist in Sentinel. We searched the forums and knowledge bases but couldn't find a solution. When you onboard new customers, you need to enable the data connectors. That part is easy, but you must create rules from scratch for every associated connector. You click "next," "next," "next," and it requires five clicks for each analytical rule. Imagine we have a customer with 150 rules."
"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."
"Multi-tenancy, in my opinion, needs to be improved. I believe it can do better as a managed service provider."
"The playbook development environment is not as rich as it should be. There are multiple occasions when we face problems while creating the playbook."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Pricing for Microsoft Sentinel could always be lower, but it's workable. The ingestion costs for the data analytics is usually the highest cost, but the licensing per Microsoft Sentinel is fairly straightforward and transparent."
"Currently, given our use case, the cost of Sentinel is justified, but it is expensive."
"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."
"We only pay for the amount of data we bring in, which is fair."
"From a cost point of view, it is not a cheap product. It's, like, an enterprise-level application. So if you compare it with a low-level application, it's expensive, but if you compare it with the same-level application, it's pretty much cost-effective, I think."
"Sentinel is pretty competitive. The pricing is at the level of other SIEM solutions."
"Sentinel is fairly priced and pretty cost-effective."
"There are no additional costs other than the initial costs of Sentinel."
