Opis duolingo.com
Duolingo appears to be the official website for Duolingo, a widely used online learning platform focused primarily on language education, with additional learning offerings such as math and chess shown on the homepage. The site presents itself as a free, gamified learning service with short lessons and account-based progress tracking, which aligns with the brand’s well-known educational product.
Based on the domain name, page title, metadata, and screenshot, the website is operated as the main web presence for the Duolingo service rather than a reseller, parked page, or placeholder domain. Its strong web visibility, long domain history, and multilingual subdomains suggest an established global education platform serving users in multiple regions and languages.
Ocena bezpieczeństwa 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 shown as clean across the checked blacklist and threat-database sources. The website content in the screenshot also appears consistent with a legitimate educational platform, with no obvious phishing prompts, fake giveaways, or deceptive download patterns.
One malware scan did label a single page reference as suspicious, but this appears to be a low-confidence heuristic signal without a named threat family and without corroboration from other scanners or blacklist sources. Given the domain’s age, high visibility, and the absence of broader detection consensus, that isolated finding may be a false positive or a non-specific pattern match rather than evidence of active harm.
Based on available data, no threats were detected at the time of this scan.
Opis techniczny
The domain has been registered for about 16 years and uses a valid SSL/TLS certificate issued through Amazon infrastructure, with hosting on AWS EC2 in the United States. The site also uses multiple AWS nameservers and serves assets through a CloudFront content-delivery domain, which is consistent with a large-scale production web platform. The observed web server identifier was "duo-api."
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses may not benefit from that additional layer of authenticity protection. Aside from that, the technical posture shown here appears typical of a mature cloud-hosted service, and no major infrastructure-level security concerns were evident from the provided scan data.
