zvei.org

We performed a comprehensive analysis of zvei.org on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 15892ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 1261 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by DigiCert Inc (OV 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 2 domain(s) (Subject Alternative Names) and expires on 2026-07-20, which is 20 days from now. The security headers analysis reveals a score of 35/100 (below average). The following security headers are properly configured: Strict-Transport-Security (HSTS) and X-Content-Type-Options. However, the site is missing Content-Security-Policy, X-Frame-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 8 technologies across 6 categories powering zvei.org. The detected stack includes Angular, React, Google Analytics 4, Matomo, Cloudflare, jQuery 3.7.1., Lodash, and Font Awesome. The site uses Angular as its primary framework. The UI is built with React. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, zvei.org receives an overall trust score of 75/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, zvei.org receives a trust score of 75/100, 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 DigiCert Inc with 20 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 zvei.org 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.

zvei.org delivers its homepage in 15892ms (server response time), which is considered slow by industry standards. The total page weight is 1261 KB, and we detected 389 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: 1 out of 9 CSS files and 11 out of 26 JavaScript files are minified. Minifying the remaining 23 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 zvei.org produces approximately 0.62g 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 1261 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for zvei.org. 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.

zvei.org resolves to the IPv4 address 88.99.102.253, 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: ns1.zvei.org and ns2.zvei.org. 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 zvei.org is handled by zvei.org with 1 MX records configured: manwe.zvei.org. 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 zvei.org, 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.

The homepage of zvei.org contains 2,125 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing. The page is structured with 14 H2 headings, 36 H3 headings, 1 H4 headings, 2 H5, and 0 H6 headings. The page includes 26 images. 20 images (77%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 23% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 299 internal links pointing to other pages on the same domain and 11 external links pointing to third-party websites. The high number of internal links suggests a well-interconnected site structure, which helps search engines discover and crawl all pages efficiently. There are 26 external JavaScript files, 9 CSS stylesheets, and 0 iframes on the page. The site implements the following web standards and features: XML Sitemap (helps search engines discover all pages), robots.txt (controls search engine crawling behavior), and Schema.org structured data (BreadcrumbList, ContactPoint, Country, ListItem, Organization, PostalAddress, WebPage, and WebSite).
