dthu.edu.vn

We performed a comprehensive analysis of dthu.edu.vn on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 5459ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 177 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Sectigo Limited (OV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 2 domain(s) (Subject Alternative Names) and expires on 2027-01-08, which is 192 days from now. The security headers analysis reveals a score of 0/100 (poor). No security headers are configured, which is a significant security concern. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 7 technologies across 7 categories powering dthu.edu.vn. The detected stack includes Google Analytics 4, Meta Pixel, Cloudflare, Google Fonts, YouTube Embed, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, dthu.edu.vn receives an overall trust score of 60/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, dthu.edu.vn receives a trust score of 60/100, which places it in the "Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit and a valid SSL certificate issued by Sectigo Limited with 192 days until expiration. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked dthu.edu.vn against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers.

The total page weight is 177 KB, and we detected 293 resource requests loading assets from 12 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 1 out of 9 CSS files and 2 out of 11 JavaScript files are minified. Minifying the remaining 17 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality.
