Hi there, Jack from CrowdSec here.
Our blocklists provide highly targeted lists of malicious IP addresses that are known to target specific services. As an example, WordPress users can subscribe to the WordPress Blocklist, which contains a list of IP addresses that are known to repeatedly target WordPress sites. Users on a free plan can subscribe to 2 of our 'third party blocklists', and if you're on a paid for plan you can subscribe to our premium blocklists as well (marked with a medal in the UI)
As for Context, you can enable this option to receive additional context with any new alerts. You can learn more about this and how to set it up here https://www.crowdsec.net/blog/simplify-threat-detection-with-alert-context
And finally, enabling console_management means your security engine is able to receive instructions directly from within the Console. You can learn some more about that here https://docs.crowdsec.net/docs/console_management/intro/
