Adelina Craciun - PeerSpot reviewer
Customization enables tailored monitoring and alerting across departments
The possibility to customize it has been quite useful. Whatever the other departments want to dream up, we implement. Whatever they want to monitor, the granularity of it, the changes in the threshold, and the anomalies that they want reported all require some development. So far, every single request has been fulfilled.
Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"The solution allows us to dig deep into data."
"It is a powerful tool that allows users to collect and transform logs as needed, enabling flexible visualization and analysis."
"We use AppDynamics and Elastic. The reason why we're using Elastic APM is because of the license count. It's very favorable compared to AppDynamics. It's inexpensive; it's economical."
"Machine learning is the most valuable feature of this solution."
"It has always been a stable solution."
"It is scalable and supports multitenancy, which is beneficial for MSPs."
"Its diverse set of features available on the cloud is of significant importance."
"I found Elk to be excellent for log analytics, security analytics, application code-level analytics, collaboration with DevOps teams, CI/CD, microservices, and Kubernetes, specifically cloud-native or cloud-specific tasks."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"There could be more low-code features included in the product."
"The solution needs to use more AI. Once the product onboards AI, users would more effectively be able to track endpoints for specific messages."
"The solution would be better if it was capable of more automation, especially in a monitoring capacity or for the response to abnormalities."
"Elastic Observability’s price could be improved."
"More web features could be added to the product."
"The price is the only issue in the solution. It can be made better and cheaper."
"Elastic Observability needs to improve the retrieval of logs and metrics from all the instances."
"Elastic Observability is reactive rather than proactive. It should act as an ITSM tool and be able to create tickets and alerts on Jira."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"The price of Elastic Observability is expensive."
"Pricing is one of those situations where the more you use it, the more you pay."
"There are two types: cloud and SaaS. They charge based on data ingestion, ingest rate, hard retention, and warm retention. I believe it costs around $25,000 annually to ingest 30GB of data daily. That is the SaaS version. There is also a self-managed license where the customer manages their own infrastructure on-prem. In such cases, there are three license tiers that respectively cost $5,000 annually per node, $7,000 per node, and $12,500 per node."
"One needs to pay for the licenses, and it is an annual subscription model right now."
"Users have to pay for some features, like the alerts on different channels, because they are unavailable in different source versions."
"We have been using the open-source version."
"Elastic Observability is cheaper than other similar solutions, such as Dynatrace. Its license calculation is based on various factors like data volume and physical infrastructure, particularly related to RAM capacity."
"So far, there are just the standard licensing fees. Several of the components are embedded in the license or are even open source. They're even free depending on what you use, which makes it even more appealing to someone that is discussing pricing of the solution."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
