diplomeo.com

We performed a comprehensive analysis of diplomeo.com on 2026-07-01. The website returned an HTTP 200 status code with a server response time of 8310ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 450 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Gandi SAS (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 6 domain(s) (Subject Alternative Names) and expires on 2027-02-24, which is 238 days from now. The security headers analysis reveals a score of 85/100 (good). The following security headers are properly configured: Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing 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 3 technologies across 3 categories powering diplomeo.com. The detected stack includes Google Analytics 4, Google Tag Manager, and AB Tasty. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, diplomeo.com receives an overall trust score of 84/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, diplomeo.com receives a trust score of 84/100, which places it in the "Very 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 Gandi SAS with 238 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a reject policy — the strongest available setting, DNSSEC providing authenticated DNS responses, and a well-established domain registered for over 15.3 years, indicating long-term commitment and legitimacy. Areas of concern include: 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 diplomeo.com 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 domain is registered through Gandi SAS based in FR, with a registration date of 2011-03-13 and expiration date of 2027-03-13.

Our technology detection engine scanned diplomeo.com and identified 3 distinct technologies across 3 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for diplomeo.com. Tag Manager: Google Tag Manager — manages marketing and analytics tags without code changes for diplomeo.com. A/B Testing: AB Tasty — enables experimentation and conversion optimization for diplomeo.com. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-AULW4HT and Google Tag Manager container GTM-WLDRH44. These IDs can be used to identify other websites operated by the same organization.

diplomeo.com delivers its homepage in 8310ms (server response time), which is considered slow by industry standards. The total page weight is 450 KB, and we detected 351 resource requests loading assets from 33 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 3 JavaScript files are minified. Minifying the remaining 4 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 diplomeo.com produces approximately 0.22g of CO₂, earning a carbon rating of B. 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 450 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for diplomeo.com. 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.

diplomeo.com resolves to the IPv4 address 51.103.19.211, 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 3 name servers: ns-157-b.gandi.net, ns-157-c.gandi.net, and ns-49-a.gandi.net. Having 3 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 diplomeo.com is handled by Microsoft 365 with 1 MX records configured: diplomeo-com.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 (Domain-based Message Authentication, Reporting and Conformance) is configured with a reject policy — the strongest setting, instructing receiving servers to reject unauthorized emails entirely. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for diplomeo.com, 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 domain is registered through Gandi SAS (FR). It was first registered on 2011-03-13 and is set to expire on 2027-03-13, making it 15.3 years old. Our subdomain enumeration scan discovered 2 active subdomains for diplomeo.com: admin.diplomeo.com and www.diplomeo.com. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of diplomeo.com contains 1,531 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, 0 H3 headings, 0 H4 headings. The page includes 53 images. 38 images (72%) 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 28% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 249 internal links pointing to other pages on the same domain and 33 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.
