A nameserver reputation score is a measure of the trustworthiness and reputation of the nameservers associated with a particular domain (or set of domains).

Threat actors often use compromised or low-reputation nameservers to host phishing or malware distribution websites or to carry out other malicious activities.

Nameserver reputation scores are calculated based on a variety of factors, including (but not limited to):

• Historical activity associated with the nameservers
• The number of domains associated with the nameservers that have been used in malicious activity
• The quality of the nameserver's security controls and practices

By focusing on domains associated with nameservers that have a low reputation score, security teams can reduce the risk of cyber attacks and protect their organization's network and data.

Silent Push provides a fast, simple lookup that allows organizations to ascertain a nameserver's reputation score, which can then be used to inform other threat intelligence activities and cyber defense operations.
