What is DomainDrift?
DomainDrift continuously monitors a large catalog of domains for changes to nameservers, mail servers, TLS certificates, hosting providers, and other infrastructure. It publishes cryptographically signed observations for security monitoring, compliance verification, and historical infrastructure research. You can set up Agent Analytics to see when DomainDrift visits your website.

Frequently Asked Questions
Should I Block DomainDrift?
Confirm DomainDrift's purpose before blocking it. Intelligence gatherers may collect competitive research, measure advertisements, or evaluate pages for brand safety. Weigh any benefit against sharing business or page-level data with its operator or clients. Almost none of the top websites we track currently have robots.txt rules for DomainDrift.
Does DomainDrift Follow Robots.txt Rules?
Yes. DomainDrift is expected to follow robots.txt rules, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether DomainDrift respects it.
Does DomainDrift Access Private Content?
No special access. DomainDrift can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.
How Can I Tell if DomainDrift Is Visiting My Website?
Agent Analytics tracks DomainDrift visits in real time. You can also check your server logs for requests whose user-agent string contains "DomainDrift". Traffic may range from repeated requests to the same pages to broader crawls or one-off fetches. Because DomainDrift does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is DomainDrift Visiting My Website?
DRM3 or one of its clients may be gathering competitive intelligence, measuring advertisements, or evaluating content for brand safety. The pages requested reflect the underlying objective.
