stema.de

We performed a comprehensive analysis of stema.de on 2026-07-08. The website returned an HTTP 200 status code with a server response time of 14497ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 147 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 21 domain(s) (Subject Alternative Names) and expires on 2026-09-16, which is 70 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-Frame-Options. However, the site is missing Content-Security-Policy, 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 1 technologies across 1 categories powering stema.de. The detected stack includes Google Analytics 4. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, stema.de receives an overall trust score of 75/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, stema.de 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 Let's Encrypt with 70 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a none policy. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked stema.de 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.

Our technology detection engine scanned stema.de and identified 1 distinct technologies across 1 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 stema.de.

stema.de delivers its homepage in 14497ms (server response time), which is considered slow by industry standards. The total page weight is 147 KB, and we detected 528 resource requests loading assets from 5 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 4 CSS files and 0 out of 3 JavaScript files are minified. Minifying the remaining 7 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 stema.de produces approximately 0.07g 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 147 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for stema.de. 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.

stema.de resolves to the IPv4 address 217.160.41.234 and also supports IPv6 (2001:8d8:1801:813b::1), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 4 name servers: ns1121.ui-dns.biz, ns1121.ui-dns.com, ns1121.ui-dns.de, and ns1121.ui-dns.org. Having 4 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 stema.de is handled by stema.de with 1 MX records configured: stema.de. 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 not enabled for stema.de. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions.

The homepage of stema.de contains 2,780 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 3 H2 headings, 2 H3 headings, 195 H4 headings, 3 H5, and 0 H6 headings. The page includes 135 images. 4 images (3%) 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 97% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 377 internal links pointing to other pages on the same domain and 6 external links pointing to third-party websites.

The site implements the following web standards and features: XML Sitemap (helps search engines discover all pages) and robots.txt (controls search engine crawling behavior). Notable missing features: Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 3 platforms: Facebook (@stema.anhaenger), Instagram (@stema_anhaenger), and Linkedin (@stema-metalleichtbau-gmbh). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.
