Event tracking has become smoother and data analytics provide clear insights for user actions
Amazon OpenSearch Service is not providing the processing feature directly. From Amazon OpenSearch Service, we are actually maintaining the AWS SQS, the queue service, which is responsible for providing information about what data has to be modified. So using that SQS, we're actually providing it, but we're not directly using Amazon OpenSearch Service for keeping data to other data pipeline thing. So far we didn't use it for any machine learning purposes, but in future, we have plans to extend or implement this feature. Since AWS itself is secure and Amazon OpenSearch Service is a part of this entire ecosystem, it becomes much easier for security purposes. From the validation point of view, Amazon OpenSearch Service itself provides easy to communicate APIs and up-to-date documents, which is much beneficial. For example, if I'm missing anything, I can directly go and check the documentation. That is actually much easier. I would rate it as really good so far. It's much faster. For our local machine, we can also use a kind of replica of Amazon OpenSearch Service just for development purposes. That is another good feature. I would say for the encryption thing and also the user access control management, it's much faster. For some of these hashing algorithms, it also worked really well so far. To be honest, I didn't find any places where it can be improved. However, I think they could provide more abstraction. For example, still for searching, we have to write down the queries in a specific manner, such as for a specific JSON structure or in a specific way. Otherwise, they don't provide us the actual results. For at least this purpose, I think abstraction could be a bit easier or a bit improved. Other than that, right now there is the age of AI, so some kind of prompting could also work, but I'm not sure how it could be integrated. As a user, lower prices or reasonable pricing is always better. Those can be improved as well. However, it is good that most of the services including Amazon OpenSearch Service actually provide pay as you go pricing. So if there were a bit lower version or a bit less payment methodology, it might be much better.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Quotes from Members

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

Pros

"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"AWS has now made our life easy."
"It's actually easier to collaborate since it is already deployed in the AWS cloud itself."
"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"
"It's a good log management platform. In terms of infrastructure management, it's good."
"In case there is a failure, Elastic manages everything well, and there no major downtime."
"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."
"Regarding valuable features of the solution, we found with the process, which we have used in both cases where we used the solution that while you're seeing the streaming of data, you can analyze in the initial phase what sort of data you are streaming and whether it is valuable."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"The most valuable features are the threat prediction and network forensics."
"The most valuable features are its ingestion of logs and raising of alerts based on those logs."
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"Alerting Module: It provides real-time event processing language on all the logs/packets stream for advanced alerting, i.e., using SQL LIKE statements."
"The most valuable features are the packet inspection and the automated incident response."
"Thanks to this tool, we have a small SOC running in our company."
"Overall, this is a good solution with suitable features and it very well fits our needs."
 

Cons

"In terms of data handling capabilities with Amazon OpenSearch Service, they can be complex and managing data in comparison to other SIM solutions is a major drawback, as it is very hard to handle the data."
"The configuration should be more straightforward because we had to select a lot of things."
"They can enhance data visualization."
"There is the problem with the database. Amazon only provides the host to run to our applications bias, but there is no option to manage the database within the Elasticsearch product."
"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."
"The configuration should be more straightforward because we had to select a lot of things."
"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."
"I would say that, basically, the configuration part is an area with a shortcoming...Some upgradation is required on the configuration side so that we can get to use it."
"RSA NetWitness Logs and Packets is far behind the competition."
"We have encountered issues with unresolved crashes."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"The user interface is a little bit difficult for new users and it needs to be improved."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"We encountered stability issues in the earlier versions, and much fewer in the newer versions."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"The product continues to crash. Even with tech support help, it does not resolve itself."
 

Pricing and Cost Advice

"You only pay for what you use."
"Compared to other cloud platforms, it is manageable and not very expensive."
"There is a community edition available and the price of the commercial offering is reasonable."
"The solution is not expensive, but priced averagely, I will say."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"The product price was reasonable for my region and the market."
"The licenses are good but the cost is very expensive."
"Our license is for one year."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"It’s cheaper to run virtual machines in a VMware environment."
