Description of maxcdn.bootstrapcdn.com
maxcdn.bootstrapcdn.com appears to be a technology infrastructure subdomain associated with BootstrapCDN, a content delivery service for popular front-end web libraries such as Bootstrap, Font Awesome, Bootswatch, and Bootstrap Icons. The page title and visible content indicate that its purpose is to provide developers with hosted CSS and JavaScript assets that can be embedded into websites for faster delivery and easier version management.
Based on the domain structure, page metadata, and on-page branding, this site appears to serve developer-facing resources rather than consumer content or transactions. It is categorized by multiple web-classification providers as technology or content delivery infrastructure, which is consistent with the screenshot showing CDN links, version references, and project-related navigation.
Safety Assessment for maxcdn.bootstrapcdn.com
The available scan data is broadly reassuring. At the time of this scan, 0 out of 91 security engines flagged the domain, and the checked blacklist and threat-database sources did not report listings associated with malware, phishing, or other content-based abuse. The domain is also long-established, with an age of about 14 years, which generally reduces the likelihood of it being a newly created disposable site.
One malware scan did label the page content as suspicious and marked 2 scanned items, but no specific malware family or corroborating detections were provided. In context, that appears to be a low-confidence heuristic signal rather than strong evidence of harmful activity, especially since other scan sources were clean and no flagged external links, domains, or iframes were reported.
Based on available data, no threats were detected at the time of this scan, though the isolated heuristic finding suggests a small degree of caution is still reasonable for any third-party web resource.
Technical Description
The site presented a valid SSL/TLS certificate issued by Google Trust Services, with expiry extending to 2026-08-01. It is hosted behind Cloudflare infrastructure, using the Cloudflare web server and an IP address in the 104.18.0.0/16 range, which is commonly associated with reverse-proxy and CDN delivery. The nameservers also point to Cloudflare, indicating that traffic management and edge delivery are likely handled through that platform.
DNSSEC appears to be unsigned at the time of this scan. That is not uncommon, but it does mean DNS responses do not benefit from DNSSEC validation. No DNS-based blocklist issues were reported, and no obvious infrastructure-level security problems were evident from the provided data.
