antt.gov.br

We performed a comprehensive analysis of antt.gov.br on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 12020ms. 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 153 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 1.2 with the ECDHE-RSA-AES128-GCM-SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 2 domain(s) (Subject Alternative Names) and expires on 2027-02-23, which is 239 days from now. The security headers analysis reveals a score of 30/100 (below average). The following security headers are properly configured: X-Frame-Options and X-Content-Type-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 4 technologies across 4 categories powering antt.gov.br. The detected stack includes Google Analytics 4, Google Tag Manager, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, antt.gov.br receives an overall trust score of 71/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, antt.gov.br receives a trust score of 71/100, 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 GlobalSign nv-sa with 239 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a quarantine policy, and a well-established domain registered for over 24.2 years, indicating long-term commitment and legitimacy. 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 antt.gov.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.

antt.gov.br delivers its homepage in 12020ms (server response time), which is considered slow by industry standards. The total page weight is 153 KB, and we detected 327 resource requests loading assets from 12 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 antt.gov.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: 0 out of 6 CSS files and 3 out of 22 JavaScript files are minified. Minifying the remaining 25 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 antt.gov.br 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 153 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for antt.gov.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.

antt.gov.br resolves to the IPv4 address 200.198.195.152, 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 2 A record(s) configured. The domain name system is managed by 2 name servers: nso.antt.gov.br and nss.antt.gov.br. 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 antt.gov.br is handled by fireeyecloud.com with 5 MX records configured: primary.us.email.fireeyecloud.com, alt1.us.email.fireeyecloud.com, and alt2.us.email.fireeyecloud.com and 2 more. 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 not enabled for antt.gov.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. Our subdomain enumeration scan discovered 3 active subdomains for antt.gov.br: api.antt.gov.br, mail.antt.gov.br, and www.antt.gov.br. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of antt.gov.br contains 896 words of visible text content. This is a moderate amount of content. The page is structured with 8 H2 headings, 8 H3 headings, 2 H4 headings, 10 H5, and 4 H6 headings. The page includes 16 images. 2 images (12%) 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 88% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 44 internal links pointing to other pages on the same domain and 206 external links pointing to third-party websites. There are 22 external JavaScript files, 6 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), and Progressive Web App (PWA) manifest (enabling app-like installation). Notable missing features: Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility.
