Activeworx SMC integrates tightly with the Snort® IDS event database to provide high valued information from your existing Snort® IDS installations, without modifying the original database schema. Whether it’s a new Snort® installation or one that has been in place for years, there has never been a more effective, less intrusive, and less expensive centralized management console for Snort.
