A decade back, network connectivity was straightforward. Companies simply operated on-premise data centers and servers. Employees used their company-owned devices to access their enterprise network. Securing the perimeter was challenging but not insurmountable. Wide-area networks (WAN), virtual private networks, and firewalls safely connected companies to their networks.

Splunk uses forwarders to ship logs to its platform and then it does the parsing and normalization. Vijilan uses its virtual appliance, ThreatSensor, to do the parsing and normalization on the prem first. This decentralized and distributed architecture felt more stable and secure than AlientVault by design. Splunk is great but costly. Vijilan partnered with Humio and crowdstrike. For large MSSPs, I’d go with vijilan.

Crowd sourced intrusion prevention information to determine bad actors based on defined scenarios which will be blocked at your installation, and reported back to the community. The more people reporting the same IPs, the worse the reputation of that IP, and the more likely it gets added to the global blocklist. The scenarios can be from crowdsedc-provided ones, or ones that you define yourself.
