SecurityZones Real-Time Cyber Threat Intelligence provides threat intelligence data and blocklists for email filtering and network security. The platform distributes threat intelligence from Spamhaus and SURBL research organizations. The product offers multiple types of blocklists including IP-based blocklists (Zen DNSBL), domain blocklists (DBL), zero reputation domains (ZRD), and hash blocklists (HBL) for filtering spam, phishing, malware, and botnet traffic. The Zen blocklist combines multiple Spamhaus IP-based blocklists to provide IP reputation data. The platform includes a Passive DNS database that stores historical DNS activity for investigation, brand monitoring, SOC operations, incident response, penetration testing, and malware research. An Intelligence API delivers threat intelligence data for integration, incident response, real-time risk assessment, and monitoring. Additional offerings include advanced threat datafeeds (Botcc, eXBL), RPZ feeds for DNS-based blocking with near real-time updates, raw spam feeds containing full messages with attachments, and URL shortener blocklists. The SURBL component provides domain reputation data on active malicious domains through Multi, Fresh, HASHBL/Shortener Feed, and DNS RPZ services. The solution is designed for integration into existing security infrastructure to enhance protection against email-based threats and cyberattacks.
