10-4.dk

We performed a comprehensive analysis of 10-4.dk on 2026-07-07. The website returned an HTTP 200 status code with a server response time of 35359ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 1514 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Let's Encrypt (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-09-17, which is 72 days from now. The security headers analysis reveals a score of 20/100 (poor). The following security headers are properly configured: Strict-Transport-Security (HSTS). However, the site is missing Content-Security-Policy, 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 9 technologies across 7 categories powering 10-4.dk. The detected stack includes Angular 21.2.17, Vite, Google Analytics 4, Microsoft Clarity, Google Tag Manager, reCAPTCHA v3, Amazon CloudFront, Google Fonts, and Adobe Fonts. The site uses Angular as its primary framework (version 21.2.17). Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, 10-4.dk receives an overall trust score of 72/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, 10-4.dk receives a trust score of 72/100, 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, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Let's Encrypt with 72 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a quarantine policy, and DNSSEC providing authenticated DNS responses. 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, and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked 10-4.dk 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.

10-4.dk delivers its homepage in 35359ms (server response time), which is considered slow by industry standards. The total page weight is 1514 KB, and we detected 589 resource requests loading assets from 15 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: 0 out of 1 CSS files and 0 out of 4 JavaScript files are minified. Minifying the remaining 5 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. From an environmental perspective, each page view of 10-4.dk produces approximately 0.74g of CO₂, earning a carbon rating of F. The website's carbon footprint could be reduced by optimizing images, enabling compression, reducing third-party scripts, and leveraging caching. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 1514 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for 10-4.dk. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

10-4.dk resolves to the IPv4 address 192.46.238.81, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: ns.scannet2.dk and ns2.scannet2.dk. Having 2 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for 10-4.dk is handled by centerasecurity.dk with 2 MX records configured: mx1-dk.centerasecurity.dk and mx2-dk.centerasecurity.dk. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a quarantine policy — a moderate setting, directing unauthorized emails to spam/junk folders. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for 10-4.dk, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites.
