tche.br

We performed a comprehensive analysis of tche.br on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 10340ms. The page is served over HTTP/1.1 protocol, however no compression (Gzip or Brotli) is enabled, which means the page is transferred at its full uncompressed size. The total page weight is 112 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by GlobalSign nv-sa (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 2026-09-14, which is 77 days from now. The security headers analysis reveals a score of 80/100 (good). The following security headers are properly configured: Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. However, the site is missing Content-Security-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 6 technologies across 6 categories powering tche.br. The detected stack includes WordPress 7.0, WooCommerce, Google Analytics 4, Google Fonts, jQuery, and Font Awesome. The primary e-commerce platform is WooCommerce. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, tche.br receives an overall trust score of 80/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, tche.br receives a trust score of 80/100, 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 GlobalSign nv-sa with 77 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, 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 tche.br 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.

tche.br delivers its homepage in 10340ms (server response time), which is considered slow by industry standards. The total page weight is 112 KB, and we detected 63 resource requests loading assets from 9 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. No compression is currently enabled on tche.br. Enabling Brotli or Gzip compression could reduce page size by 60-80% for text-based assets (HTML, CSS, JavaScript), significantly improving load times and reducing bandwidth costs. This is one of the simplest and most impactful performance optimizations available. Asset minification status: 3 out of 11 CSS files and 5 out of 8 JavaScript files are minified. Minifying the remaining 11 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 tche.br produces approximately 0.05g 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 112 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for tche.br. 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.

tche.br resolves to the IPv4 address 200.132.0.134 and also supports IPv6 (2804:0:0:cafe::134), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 3 name servers: delta.tche.br, dns.tche.br, and polvo.tche.br. 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 tche.br is handled by tche.br with 2 MX records configured: smtp.tche.br and smtp.pop-rs.rnp.br. 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 tche.br. 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 tche.br contains 218 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 0 H2 headings, 2 H3 headings, 1 H4 headings. The page includes 5 images. 5 images (100%) 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 0% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 14 internal links pointing to other pages on the same domain and 10 external links pointing to third-party websites. There are 8 external JavaScript files, 11 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), Schema.org structured data (BreadcrumbList, ImageObject, ListItem, Organization, WebPage, and WebSite), and RSS feed for content syndication. The website has social media presence across 2 platforms: Facebook (@poprsRNP) and Instagram (@poprs.metropoa). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.

The title tag for tche.br is good at 26 characters: "Página inicial - Rede Tchê". The length is acceptable, though it may be slightly truncated in some search result displays. The meta description is 279 characters (slightly long): "O que é a Rede Tchê? A Rede Tchê é uma rede de computadores que integra universidades e centros de pesquisa localizados ...". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results.

Open Graph meta tags are configured with 4/4 recommended fields: OG title ("Página inicial - Rede Tchê..."), OG description, OG image (social sharing thumbnail), OG type (article). 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, ImageObject, ListItem, Organization, 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.
