+ Get more context around domain names, IP adresses, urls and file hashes using the
+ [SEKOIA.IO](https://sekoia.io) Intelligence Database.
+
+ The analyzer comes in 2 flavors:
+
+ - SEKOIAIntelligenceCenter_**Indicators**: Find indicators matching the observable provided.
+ - SEKOIAIntelligenceCenter_**Context**: Get indicators and their context for the observable provided.
+
+#### Requirements
+ You need an active [SEKOIA.IO Intelligence Center](https://sekoia.io/) subscription to use the analyzer:
+
+- Provide your API key as a value for the `api_key` parameter.
