Corelight was founded by the creators of the open-source Bro project. Bro data is 100x richer than netflow data, 100x smaller than traditional packet capture (PCAP), and, anecdotally, provides 20x faster Digital Forensics and Incident Response (DFIR). Corelight makes Bro enterprise ready.
Corelight also makes deploying sensors easy.
