Cybersixgill DarkfeedvsGreyNoise Intelligence

Cybersixgill Darkfeed is an automated, contextual threat intelligence feed that delivers malicious indicators of compromise (IOCs) harvested directly from deep and dark web sources, underground hacking forums, invite-only Telegram groups, and ransomware leak sites. Darkfeed extracts actionable intelligence the moment threat actors share or weaponize malware tools. Enriched with full threat actor context and MITRE ATT&CK mapping, Darkfeed automatically streams into enterprise firewalls, SIEMs, SOARs, and endpoint platforms like CrowdStrike Falcon. Security systems can immediately blacklist malicious hashes, phishing URLs, and C2 IPs automatically without human intervention, neutralizing attacks at the earliest stage of the cyber kill chain.

GreyNoise Intelligence operates a globally distributed sensor network that passively monitors internet background noise and scans. It analyzes, classifies, and illuminates opportunistic internet-wide scanners, botnets, academic research bots, and search engine crawlers, empowering security teams to differentiate benign internet noise from targeted cyber attacks. By integrating GreyNoise into SIEM, SOAR, and TIP systems, SOC analysts can automatically filter out 20% to 50% of false-positive perimeter alerts generated by non-targeted internet scanning. Additionally, GreyNoise SIFT tracks real-time exploit waves against newly published CVEs as they happen in the wild.
