uol.com.br

We performed a comprehensive analysis of uol.com.br on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 17797ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 784 KB, and the site is served behind a CDN (Content Delivery Network). Warning: The website does not have a valid SSL certificate. Visitors may see security warnings in their browser, and data transmitted to and from this website is not encrypted. The security headers analysis reveals a score of 55/100 (moderate). The following security headers are properly configured: Content-Security-Policy, Strict-Transport-Security (HSTS), and Referrer-Policy. However, the site is missing X-Frame-Options, X-Content-Type-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 3 technologies across 3 categories powering uol.com.br. The detected stack includes WordPress, Webpack, and Google Analytics 4. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, uol.com.br receives an overall trust score of 70/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, uol.com.br receives a trust score of 70/100, 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, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none policy, and DKIM (DomainKeys Identified Mail) providing cryptographic email verification. Areas of concern include: no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), 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 uol.com.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.

Our technology detection engine scanned uol.com.br 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. CMS: WordPress — manages the content and page structure for uol.com.br. Build Tool: Webpack — bundles and optimizes the JavaScript and CSS assets for uol.com.br. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for uol.com.br. We also extracted the following tracking identifiers: Intercom App ID 190329594333794. These IDs can be used to identify other websites operated by the same organization.

uol.com.br delivers its homepage in 17797ms (server response time), which is considered slow by industry standards. The total page weight is 784 KB, and we detected 839 resource requests loading assets from 27 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 0 CSS files and 1 out of 20 JavaScript files are minified. Minifying the remaining 19 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. The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors. From an environmental perspective, each page view of uol.com.br produces approximately 0.38g of CO₂, earning a carbon rating of C. This is an average carbon footprint. Optimizing images and reducing unnecessary scripts could further improve this score. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 784 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for uol.com.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.

uol.com.br resolves to the IPv4 address 200.147.35.149 and also supports IPv6 (2804:49c:3102:401:ffff:ffff:ffff:36), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 3 name servers: borges.uol.com.br, charles.uol.com.br, and eliot.uol.com.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 uol.com.br is handled by com.br with 1 MX records configured: mx.uol.com.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 (DomainKeys Identified Mail) is configured, adding a cryptographic signature to outgoing emails that receiving servers can verify to confirm the email hasn't been tampered with in transit. DNSSEC is not enabled for uol.com.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 10 active subdomains for uol.com.br: api.uol.com.br, app.uol.com.br, blog.uol.com.br, ftp.uol.com.br, m.uol.com.br, mail.uol.com.br, shop.uol.com.br, and smtp.uol.com.br. Plus 2 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
