Descripción de u20443333.ct.sendgrid.net
The domain u20443333.ct.sendgrid.net appears to be part of SendGrid's infrastructure, likely used for email delivery, click tracking, or related web and email marketing functions. The subdomain structure and available categorization data suggest it supports business and information-technology services rather than operating as a standalone consumer-facing website.
Based on the domain naming pattern, this host is likely operated within a larger cloud email platform environment rather than by an independent publisher or retailer. The classifications provided by multiple web-categorization sources align with business, IT, and web/email marketing activity, which is consistent with transactional email and campaign infrastructure.
Evaluación de seguridad de u20443333.ct.sendgrid.net
Available scan results show no detections from 0 out of 92 security engines at the time of this scan. Malware scanning also reported no flagged files, and major blacklist and threat-database checks were clean, with the exception of one generic blacklist-style listing that labeled the host with a non-specific suspicious-object heuristic. Because that signal was generic and not corroborated by broader engine detections, it appears to be a lower-confidence concern based on the available data.
Additional context modestly supports legitimacy: the domain has been registered for many years, uses a valid SSL certificate, and sits on infrastructure that is consistent with large-scale cloud-hosted service delivery. The domain also appears tied to established email-marketing or messaging infrastructure rather than a newly created or obviously deceptive website.
Based on available scan data, no significant threats were detected at the time of this scan.
Descripción técnica
The host presented a valid SSL/TLS certificate issued by GoDaddy.com, Inc., with expiry listed as 2026-06-12. It resolves to 3.79.169.2 and appears to be served by nginx on AWS EC2 infrastructure in the eu-central-1 region (Frankfurt am Main, Germany). The domain is long-established, with creation dating to 2009, and uses MarkMonitor Inc. as registrar, which is commonly associated with enterprise domain management.
DNSSEC appears to be unsigned, which is not uncommon but does mean DNS responses do not benefit from DNSSEC validation. No malicious files, external links, or iframe activity were reported in the provided scan data, and blacklist checks were broadly clean aside from one generic heuristic-style listing.
