Description de u29557106.ct.sendgrid.net
u29557106.ct.sendgrid.net appears to be a subdomain associated with SendGrid, a cloud-based email delivery and transactional messaging platform used by businesses and applications to send marketing emails, notifications, and account-related messages. The "ct" portion of the hostname may indicate click-tracking or link-tracking infrastructure commonly used in email campaigns, while the numeric prefix likely identifies a specific customer or account-related routing endpoint.
Based on the domain structure and infrastructure details, this host appears to be part of enterprise email service infrastructure rather than a standalone public-facing website with editorial or retail content. The parent domain is long-established, uses a major corporate registrar, and is hosted on mainstream cloud infrastructure, which is consistent with large-scale SaaS messaging operations.
Évaluation de sécurité de u29557106.ct.sendgrid.net
At the time of this scan, no security engines reported detections for this host, and the malware scan did not identify any flagged files, suspicious external links, or iframe activity. In addition, the checked blacklist and threat-database sources did not report the domain as listed. These are generally favorable indicators for a messaging-related subdomain.
The domain has a long registration history of about 17 years, which can be a positive trust signal when considered alongside the clean scan results. It is also worth noting that this is a service subdomain rather than a typical consumer website, so its purpose may be limited to email tracking or redirection functions within a larger communications platform.
Based on available data, no threats were detected at the time of this scan.
Description technique
The host presented a valid SSL/TLS certificate issued by a mainstream certificate provider, with validity extending to December 2026. It resolves to an nginx web server hosted on AWS EC2 in the Frankfurt region, which is consistent with modern cloud-based service deployment. The domain uses DNS Made Easy nameservers and is registered through a major corporate registrar.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No immediate technical security concerns were evident from the provided scan data beyond that observation.
