rostender.info

We performed a comprehensive analysis of rostender.info on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 3764ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 142 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 2027-01-17, which is 201 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-Content-Type-Options. However, the site is missing Content-Security-Policy, X-Frame-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 4 technologies across 4 categories powering rostender.info. The detected stack includes Bootstrap, Google Analytics 4, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, rostender.info receives an overall trust score of 75/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, rostender.info 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 GlobalSign nv-sa with 201 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 14.5 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, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), 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 rostender.info 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. The domain is registered through Regional Network Information Center, JSC dba RU-CENTER based in RU, with a registration date of 2012-01-12 and expiration date of 2027-01-12.

rostender.info delivers its homepage in 3764ms (server response time), which is considered slow by industry standards. The total page weight is 142 KB, and we detected 189 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. 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: 10 out of 12 CSS files and 27 out of 39 JavaScript files are minified. Minifying the remaining 14 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 rostender.info 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 142 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for rostender.info. 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.

rostender.info resolves to the IPv4 address 5.188.82.8, 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 4 name servers: a.ns.selectel.ru, b.ns.selectel.ru, c.ns.selectel.ru, and d.ns.selectel.ru. 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 rostender.info is handled by nicmail.ru with 3 MX records configured: mx02.nicmail.ru, mx01.nicmail.ru, and mx03.nicmail.ru. 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 rostender.info. 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 domain is registered through Regional Network Information Center, JSC dba RU-CENTER (RU).
