Description of duolingo.com
Duolingo appears to be a major online education platform focused on language learning, with additional learning content such as math and chess shown on the homepage. The site presents itself as a free, gamified learning service with short lessons, multilingual localization, and account-based access for returning users.
Based on the domain, page metadata, and global popularity signals, this website appears to be the official web presence of Duolingo, a well-known educational technology company. The homepage design, localized subdomains, and supporting infrastructure suggest a mature, actively maintained service intended for a broad international audience.
Safety Assessment for duolingo.com
The scan results are broadly reassuring at the time of this scan. No detections were reported by 0 out of 91 security engines, and the domain was not listed on the checked blacklist databases. External links and referenced domains also did not show flagged results in the provided scan data, which may indicate a relatively low level of observable malicious activity from the homepage during this assessment.
One malware scan labeled the site as suspicious and marked a single entry related to the homepage fragment URL, but no specific threat name was provided. In context, that isolated result may reflect a heuristic or non-specific scan artifact rather than confirmed malicious behavior, especially given the domain's long operating history, strong reputation indicators, and absence of corroborating detections from other scanners.
The domain is longstanding, highly ranked, and consistent with a widely recognized educational platform. Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The site uses a valid SSL/TLS certificate issued through Amazon infrastructure, with certificate validity extending to late 2026. Hosting appears to be on AWS EC2 in the United States, and the domain uses Amazon nameservers. The observed web server identifier was "duo-api," and the site references assets from a CloudFront content delivery domain, which is consistent with a large-scale web application.
DNSSEC appears to be unsigned, which is not uncommon but does mean DNS responses may not benefit from that additional integrity layer. Aside from the single non-specific suspicious heuristic in one malware scan, the provided technical indicators do not show major infrastructure-level security concerns at the time of this scan.
