fondationvasarely.org

We performed a comprehensive analysis of fondationvasarely.org on 2026-07-02. The website returned an HTTP 200 status code with a server response time of 31658ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 192 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 4 domain(s) (Subject Alternative Names) and expires on 2026-09-17, which is 77 days from now. The security headers analysis reveals a score of 30/100 (below average). The following security headers are properly configured: X-Content-Type-Options and Referrer-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, 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 8 categories powering fondationvasarely.org. The detected stack includes WordPress 6.9.4, Bootstrap, Google Analytics 4, Google Tag Manager, Google Fonts, Vimeo, YouTube Embed, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, fondationvasarely.org receives an overall trust score of 73/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, fondationvasarely.org receives a trust score of 73/100, 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, a valid SSL certificate issued by Let's Encrypt with 77 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none 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), 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 fondationvasarely.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.

fondationvasarely.org delivers its homepage in 31658ms (server response time), which is considered slow by industry standards. The total page weight is 192 KB, and we detected 141 resource requests loading assets from 13 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: 9 out of 26 CSS files and 14 out of 32 JavaScript files are minified. Minifying the remaining 35 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 fondationvasarely.org produces approximately 0.09g 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 192 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for fondationvasarely.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.

fondationvasarely.org resolves to the IPv4 address 147.135.191.221, 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: dns112.ovh.net and ns112.ovh.net. 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 fondationvasarely.org is handled by Google Workspace with 1 MX records configured: smtp.google.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 (Domain-based Message Authentication, Reporting and Conformance) is configured with a none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for fondationvasarely.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 fondationvasarely.org contains 159 words of visible text content. This is a relatively short page — adding more descriptive content could improve search engine visibility. The page is structured with 1 H2 headings, 0 H3 headings, 4 H4 headings. The page includes 10 images. 3 images (30%) 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 70% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 34 internal links pointing to other pages on the same domain and 18 external links pointing to third-party websites. There are 32 external JavaScript files, 26 CSS stylesheets, and 1 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), Schema.org structured data (BreadcrumbList, EntryPoint, ImageObject, ListItem, Organization, PropertyValueSpecification, ReadAction, SearchAction, WebPage, and WebSite), and RSS feed for content syndication.

An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.

The title tag for fondationvasarely.org is well-optimized at 39 characters: "Fondation Vasarely - Fondation Vasarely". The length falls within the ideal range for Google search results, ensuring the full title is displayed without truncation. No meta description is configured for fondationvasarely.org. This is a critical SEO oversight — without a meta description, Google will auto-generate a snippet from page content, which may not accurately represent the page or entice users to click. Adding a unique, compelling meta description of 120-155 characters is strongly recommended. The canonical url is correctly set to https://www.fondationvasarely.org/, preventing duplicate content issues, the page language is declared as fr-fr, the meta robots directive is set to index, follow, max-image-preview:large, max-snippet:-1, max-video-preview:-1, and a favicon is configured. Open Graph meta tags are configured with 3/4 recommended fields: OG title ("Fondation Vasarely - Fondation Vasarely..."), OG description, OG type (website). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. A Twitter Card of type summary_large_image is configured, which controls how links appear when shared on Twitter/X. The "summary_large_image" type displays a large image preview, which typically generates higher engagement rates than the basic card type. The site implements Schema.org structured data with the following types: BreadcrumbList, EntryPoint, ImageObject, ListItem, Organization, PropertyValueSpecification, ReadAction, SearchAction, WebPage, and WebSite. Structured data helps search engines understand the page content and can enable rich results (featured snippets, knowledge panels, star ratings) in Google search results, which can significantly increase click-through rates.
