keirin.jp Overview

Description of keirin.jp

keirin.jp appears to be the official Japanese portal for keirin bicycle racing, offering race schedules, live viewing links, results, rankings, beginner guides, and online voting services. The page title and on-page branding identify it as an official keirin website, and the homepage layout prominently features current race events, login access for internet voting, and informational resources for fans and participants.

Based on the domain name, page metadata, and screenshot, the site appears to serve as a central hub for Japan's keirin ecosystem rather than a general news or entertainment blog. Its long-established domain history and strong traffic ranking suggest it is a well-known destination within its niche, focused on race information, account access, and regulated betting-related services tied to keirin events.

Safety Assessment for keirin.jp

The available scan data is largely reassuring at this point in time. No detections were reported by 0 out of 91 security engines, and the domain was shown as clean across the checked blacklist and threat-database sources. The domain is also longstanding, with roughly 25 years of history, which generally reduces the likelihood of it being a throwaway or newly created abuse site.

One malware scan did flag a single page and one referenced external banking link with a generic malicious classification. However, this appears to be an isolated heuristic-style finding rather than a broadly corroborated threat signal, especially since other security engines and blacklist sources did not report corresponding issues at the time of this scan. In cases like this, a lone generic detection may reflect a false positive, a legacy reference, or context that automated scanners interpreted conservatively.

Based on available scan data, no significant threats were detected at the time of this scan, though users should keep in mind that scan results are point-in-time and may change if site content or linked resources are updated.

Technical Description

The site uses a valid SSL/TLS certificate issued by DigiCert, with validity extending to 2027-02-28. It is delivered through AWS CloudFront infrastructure, with the observed server IP resolving to a global CDN edge location and the web server identified as WebOTX_Web_Server. This setup is consistent with a large, established website using content delivery infrastructure for performance and availability.

The domain is approximately 25 years old and uses AWS nameservers. DNSSEC appears to be unsigned, which is not uncommon but does mean DNS responses do not benefit from that additional layer of authenticity protection. No major infrastructure-level security concerns were evident from the provided data beyond the isolated generic scanner flag on one page and one external link.
