Effective as a vector store, serverless architecture but there aren't enough security features

The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing. Even being serverless, it incurs charges during idle times. For just holding data, you need to create a list. AWS should add an option to make data idle, so it won't include computing charges. They charge for OCU units based on the time the serverless solution is up, not on indexing or retrieval speed. Once the service starts, it starts getting billed. It would help if there were an option to limit computing. When using it as a database, storing data without frequent fetching would save computing costs.

It's a user-friendly open-source solution that can replace or augment a commercial product in some cases

I rate syslog-ng 10 out of 10. It's free and easy to use. It has built-in tools that help us index the various logs sent to it. It's a solid log product. If you're looking for a SIEM solution, syslog-ng will work as a stopgap measure at beginning of the project. It can also work as an injector for a true SIEM solution. You can send all the logs to syslog-ng and forward all the data to the SIEM solution after you've cleaned up the data and got the pertinent information. It's a good front end for a commercial SIEM solution, which becomes more expensive as you load more data into it. I would highly recommend syslog-ng for that use case. However, if you lack the expertise, you might need to go with a cloud-based SIEM instead. You need some in-house expertise or an outside consultant to manage it and set it up.
