DNS Intelligence

Powerful data for discovery and attribution

Using our DNS traffic aggregation methods - which have amassed hundreds of TBs of data - we scan and analyze traffic to detect anomalies which are then used to classify potential DNS attacks. By using a blend of advanced machine learning and correlation techniques, our available intelligence can aid in detecting attacks such as DNS Cache Poisoning, DNS Spoofing, Reflection and DNS Amplification.

Threat Intelligence

Detect and identify digital threats

Detect abusive domains and IPs, matching them against hundreds of public and private reputation feeds. Our platform provides all the best goodies such as advanced search, correlation, etc. right in the web portal and it is capable of delivering threat intelligence directly to your corporate security gateway or firewall.

ZeroGuard’s proprietary technology was developed for use in red teaming, threat hunting and incident response engagements. It provides valuable visibility and event correlation across your entire security environment, thus determining the potential impact of a threat and reducing both detection time and response effort.


ZeroGuard engages and deceives hackers, which helps us identify malicious actors and nasty behaviours.

IP Reputation

Confidently determine whether a particular IP address is or was used by any bad actors to spread malware, take part in DDOS attacks, send spam, attempt ransomware, etc.

Command & Control

Detect and block known command & control hosts, ensuring your servers won’t get infected and become part of a botnet.


Cross referencing with our threat intel databases, we flag, identify and quarantine various spyware, Trojan Horses, worms and viruses.
