Azam S M - PeerSpot reviewer
Infrastructure Lead at Danat Fz LLC
Has provided reliable monitoring and alerting through extensive metric tracking and dashboard configuration
Amazon CloudWatch itself provides a lot of data. However, for visualization, we need to use third-party tools. We are in a process of integrating Grafana, Loki, and Prometheus to have better visualization on Amazon CloudWatch. We are also integrating Grafana with the application itself to get the application data and logs. Alternatively, there is AWS Kinesis and Glue where you can scrape the logs and have visualization, but a more easy option is Grafana. If you want to get a proper visual representation to see what is happening, then you need to integrate a third-party tool. Amazon CloudWatch has all the data, but to see what is happening, you need some third-party tool.
Hiten Nandasana - PeerSpot reviewer
Angular developer at Flourish software
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

"Our team finds it overall quite useful."
"The solution effectively monitors golden signals like CPU, page requests, and queues."
"It offers direct integrations with various storage providers, making it convenient to push logs from CloudWatch to these external platforms."
"The most valuable part is the metrics part, which is really good."
"The alarms are one thing I love about AWS CloudWatch. It has alerts that notify us when resource use is approaching the limit."
"The most valuable feature of Amazon CloudWatch is the monitoring and UI."
"Setting up this product was easy. I found data analytics as its most valuable feature."
"The solution gives us very good real-time data."
"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 is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."

Cons

"Adding conditional expressions would enhance its functionality."
"This product lacks some features: real-time data stream monitoring, application performance monitoring, mobile app monitoring, and live dashboards. Its workflows also need improvement."
"The product should provide more features."
"The solution should provide human-readable metrics."
"The drill-down aspect on the dashboard of the solution needs improvement."
"There is room for improvement in the pricing, because they have a premium version, but it's not really a premium version. It's just an enhanced monitoring version, and it can be a bit expensive depending on your usage."
"What would make Amazon CloudWatch better is if it includes more on-site checks, particularly status checks on the CPU, network input/output, etc. It would also be helpful if there's built-in swap space, disk, and memory monitoring in Amazon CloudWatch because, at the moment, my team has to configure it manually through a shell script."
"The integration with third-party tools must be made easier."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"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 initial setup of the solution is a little bit difficult."
