arkon.dk Trust Score & Safety Analysis
🤖 AI Summary
After conducting a thorough safety and legitimacy analysis, arkon.dk receives a trust score of 58/100, which places it in the "Caution Advised" 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, SPF (Sender Policy Framework) email authentication preventing email spoofing, 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 arkon.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.

arkon.dk Performance, Speed & Core Web Vitals
🤖 AI Summary
arkon.dk delivers its homepage in 15755ms (server response time), which is considered slow by industry standards. The total page weight is 199 KB, and we detected 194 resource requests loading assets from 7 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: 5 out of 43 CSS files and 13 out of 45 JavaScript files are minified. Minifying the remaining 70 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.
The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors.
From an environmental perspective, each page view of arkon.dk produces approximately 0.1g of CO₂, earning a carbon rating of A. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 199 KB is the primary factor in this calculation.
Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for arkon.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.

arkon.dk DNS Records, Email Authentication & Domain Registration
🤖 AI Summary
arkon.dk resolves to the IPv4 address 162.159.135.42, 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: ns01.one.com and ns02.one.com. 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 arkon.dk is handled by Microsoft 365 with 1 MX records configured: arkon-dk.mail.protection.outlook.com. 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 is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic.
DNSSEC is enabled for arkon.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.
Our subdomain enumeration scan discovered 25 active subdomains for arkon.dk: admin.arkon.dk, api.arkon.dk, app.arkon.dk, apps.arkon.dk, blog.arkon.dk, cdn.arkon.dk, community.arkon.dk, and dev.arkon.dk. Plus 17 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
