rcomserver.com.br

We performed a comprehensive analysis of rcomserver.com.br on 2026-07-01. The website returned an HTTP 200 status code with a server response time of 8771ms. The page is served over HTTP/1.1 protocol with Gzip compression enabled, achieving approximately 0.4% size reduction. The total page weight is 36 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 1.2 with the ECDHE-ECDSA-AES256-GCM-SHA384 cipher suite and ECDSA-SHA384 signature algorithm. The certificate covers 2 domain(s) (Subject Alternative Names) and expires on 2026-09-26, which is 87 days from now. The security headers analysis reveals a score of 100/100 (excellent). The following security headers are properly configured: Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. All recommended security headers are in place, providing comprehensive protection against common web attacks. Our technology detection scan identified 2 technologies across 2 categories powering rcomserver.com.br. The detected stack includes Google Analytics 4 and jQuery. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, rcomserver.com.br receives an overall trust score of 82/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, rcomserver.com.br receives a trust score of 82/100, 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 Let's Encrypt with 87 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a reject policy — the strongest available setting, and a well-established domain registered for over 13.3 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 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 rcomserver.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 rcomserver.com.br and identified 2 distinct technologies across 2 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 rcomserver.com.br. JavaScript Library: jQuery — provides utility functions and DOM manipulation for rcomserver.com.br. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-L97S2XH920. These IDs can be used to identify other websites operated by the same organization.

rcomserver.com.br delivers its homepage in 8771ms (server response time), which is considered slow by industry standards. The total page weight is 36 KB, and we detected 136 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 0.4% 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 5 CSS files and 0 out of 6 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 rcomserver.com.br produces approximately 0.02g 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 36 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for rcomserver.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.

rcomserver.com.br resolves to the IPv4 address 137.131.130.23, 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: ns1.registrocom.com.br, ns2.registrocom.com.br, and ns3.registrocom.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 rcomserver.com.br is handled by com.br with 1 MX records configured: rcomserver.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 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 not enabled for rcomserver.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 2 active subdomains for rcomserver.com.br: mail.rcomserver.com.br and www.rcomserver.com.br.
