Has provided powerful customization for unique monitoring needs but needs more out-of-the-box capabilities

In my opinion, the best features of Elastic Observability are their flexibility to integrate with other existing systems and the ability to build a unified monitoring tool that can integrate with existing ones and end-to-end user journeys which require a lot of customizations. The greatest feature in Elastic is the ability to customize. This is similar to my comments about customizable dashboards in Elastic because it's visible to the analyst. However, it's very great. Customizing these dashboards can meet the customer's specific use cases and specific stories that they have in their environment, their special environment that doesn't look like other environments. The dashboarding in Elastic is highly customizable to the level of logos. If the customer wants his company logo in the dashboard, it can be done.

Centralized threat monitoring has improved visibility but demands complex setup and configuration

The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Quotes from Members

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

Pros

"Elastic Observability is highly stable; we ingested nearly 170 million records in the system and we have tested it, and you get your reports and dashboards within a few seconds, so it doesn't take much time."

"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."

"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."

"It is scalable and supports multitenancy, which is beneficial for MSPs."

"I recommend Elastic Observability for its completeness of vision and wide ecosystem."

"It is a powerful tool that allows users to collect and transform logs as needed, enabling flexible visualization and analysis."

"Elastic Observability significantly improves incident response time by providing quick access to logs and data across various sources. For instance, searching for specific keywords in logs spanning over a month from multiple data sources can be completed within seconds."

"The architecture and system's stability are simple."

More Elastic Observability pros

"We use Security Onion for internal vulnerability assessment."

"Security Onion has positively impacted my organization by greatly improving our security posture, making alert triage easier to handle, simplifying the analysis of threats, and decreasing the cost of threat analysis and detection."

"Security Onion is the most mature solution in the market."

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

Cons

"Elastic Observability’s price could be improved."

"The only challenging aspect for new users is often writing the query language."

"Elastic Observability is difficult to use. There are only three options for customization but this can be difficult for our use case. We do not have other options to choose the metrics shown, such as CPU or memory usage."

"Elastic APM's visualization is not that great compared to other tools. It's number of metrics is very low."

"Elastic Observability needs to improve the retrieval of logs and metrics from all the instances."

"Elastic Observability could improve asset discovery as the current requirement to push the agent is not ideal."

"The interface could be improved."

"With Elastic, you need to code and program more things compared to Dynatrace."

More Elastic Observability cons

"The product is not easy to learn."

"Security Onion's user interface could be improved."

"The initial setup of the solution is a little bit difficult."

"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."

Pricing and Cost Advice

"Users have to pay for some features, like the alerts on different channels, because they are unavailable in different source versions."

"The product’s pricing needs improvement."

"The product is not that cheap."

"The price of Elastic Observability is expensive."

"Pricing is one of those situations where the more you use it, the more you pay."

"We have been using the open-source version."

"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."

"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."
