DNSSense
DNSSense
DNSEye detects malicious traffic on your network and reports whether this traffic can be blocked by your other security devices. DNS is used by all protocols like HTTP, HTTPS, SMTP, and IoT. DNS traffic provides information about your entire network, regardless of its network protocol. With DNS tunnelling, data exfiltration attacks cannot be detected by DLP products. It requires DNS log analysis for an effective solution. 80% of malware domains currently do not have an IP address. Malware requests that do not have an IP address can only be detected in the DNS log. DNSservers generate a large number of difficult-to-understand logs. DNSEye enables the collection, enrichment, and AI-based classification of the DNS logs. With its advanced SIEM integration, it saves time and EPS by transferring to SIEM only the data that SOC teams need to see. DNSEye can collect logs from many different brands and models of DNS servers without the need for making any change in your network structure.Starting Price: $1000 -

Core CSP
Core Security (Fortra)
Core CSP is a purpose-built security system that is designed to monitor Internet Service Provider (ISP) and telecommunications subscribers for cyberthreats. This lightweight and scalable service provider solution passively monitors extremely large networks and identifies malicious activity on a subscriber network originating from PC, tablet, and mobile devices. ISPs and telecommunications companies must increasingly fend off cyber threats that hijack bandwidth capabilities. These attacks put subscribers at risk of having credentials stolen, falling victim to fraudulent transactions, or having devices commandeered and used for cryptomining, botnets, or other persistent attacks. DDoS attacks, often committed by botnets, are particularly problematic because they consume bandwidth with floods of requests, disrupting normal traffic or crashing the infrastructure entirely. Threat actors use networks to access any number of unsuspecting targets. -
