Real-time dashboards and visual insights have streamlined issue analysis and monitoring

After careful consideration about areas for improvement in Elastic Observability, aspects such as pricing, customization, implementation, and scalability could be improved. As a user of the system, I know what it costs but am not directly involved in cost-benefit evaluations or maintenance, which is handled by another team. I develop the visual representation of the data and frankly, I don't see major gaps in my application or anything I would really miss; I appreciate the fast pace of the developments that have occurred in the last couple of years. Regarding room for improvement in Elastic Observability, I would have preferred built-in tools to manage the indexes on deployment for better visual representation, as the initial feedback regarding system performance and data storage was fairly primitive and lacking.

Centralized monitoring has strengthened threat detection and supports faster incident investigations

Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization. Security Onion integrates well with our existing tools, primarily using Linux systems in our organization, allowing us to monitor logs and manage threat detection and operations in the public cloud effectively. Security Onion is very helpful in meeting compliance requirements and supports regular standards for our environment. I advise organizations that use Linux or have network security knowledge to consider Security Onion, as it satisfies requirements such as threat detection and log management systems. I would rate this review eight out of ten.

Quotes from Members

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

Pros

"It's easy to deploy, and it's very flexible."

"The solution is open-source and helps with back-end logging. It is also easy to handle."

"Good design and easy to use once implemented."

"I have built a mini business intelligence system based on Elastic Observability."

"For full stack observability, Elastic is the best tool compared with any other tool like New Relic or AppDynamics or Dynatrace."

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

"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."

"In addition to the fact that we are more proactive in the detection of incident before they occur, we can on one click see the request path from the customer to the backend."

More Elastic Observability pros

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

"We use Security Onion for internal vulnerability assessment."

"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."

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

Cons

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

"If we had some pre-defined templates for observability that we could start using right away after deploying it – instead of having to build or to change some of the dashboards – that would be helpful."

"Elastic support really struggles in complex situations to resolve issues."

"The price is the only issue in the solution. It can be made better and cheaper."

"Simplifying the parsing of logs and manual efforts would also be beneficial."

"The solution needs to use more AI. Once the product onboards AI, users would more effectively be able to track endpoints for specific messages."

"Elastic Observability is reactive rather than proactive. It should act as an ITSM tool and be able to create tickets and alerts on Jira."

"There is room for improvement regarding its APM capabilities."

More Elastic Observability cons

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

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"The product is not easy to learn."

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

Pricing and Cost Advice

"The product is not that cheap."

"Elastic Observability's pricing could be better for small-scale users."

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

"Since we are a huge company, Elastic Observability is an affordable solution for us."

"The price of Elastic Observability is expensive."

"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."

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

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