**What do you like best about Siren?**

I've been a customer of Siren in 3 roles spanning 10 years, and its been a great companion to shared success.  Siren was the missing piece between raw data and cyber threat intelligence production. In order to analyze data from many different sources, often highly dynamic sources, it requires a very flexible data model; there is no other product that handles this specific challenge better than Siren. The existing field of analysis solutions is really limited to search, not relational navigation, or even really supporting data modeling at all – let alone a flexible data model that analysts can easily tune.

**What do you dislike about Siren?**

Downsides are only really with the limitation of the backend technology choices (Elasticsearch). This can be mitigated with a wide range of JDBC connections to integrate other data sources, but you still need an ES cluster. Its also priced per data node, so that needs to be considered.

**What problems is Siren solving and how is that benefiting you?**

Data modeling is the primary challenge Siren is solving for us; its a powerful investigative capability and very flexible in the hands of just an analyst, where as other processes for data modeling new data sources typically require more cross-domain expertise.

All the Firms are developing at their own pace, but it would be great to reach out to many more countries. For eg;  India.
