onliner.by

We performed a comprehensive analysis of onliner.by on 2026-07-02. The website returned an HTTP 200 status code with a server response time of 45024ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 589 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 2027-02-21, which is 234 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 onliner.by. The detected stack includes Vite, Google Analytics 4, Google Tag Manager, and Google Ads. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, onliner.by receives an overall trust score of 73/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, onliner.by receives a trust score of 73/100, 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 234 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a reject policy — the strongest available setting. 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 onliner.by 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 onliner.by and identified 4 distinct technologies across 4 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records.

These IDs can be used to identify other websites operated by the same organization.

onliner.by delivers its homepage in 45024ms (server response time), which is considered slow by industry standards. The total page weight is 589 KB, and we detected 762 resource requests loading assets from 13 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 6 CSS files and 1 out of 11 JavaScript files are minified. Minifying the remaining 16 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 onliner.by produces approximately 0.29g 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 589 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for onliner.by. 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.

onliner.by resolves to the IPv4 address 178.124.129.14, 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: u1.hoster.by and u2.hoster.by. 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 onliner.by is handled by yandex.net with 1 MX records configured: mx.yandex.net. 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 onliner.by. 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 onliner.by: admin.onliner.by, api.onliner.by, app.onliner.by, blog.onliner.by, cdn.onliner.by, dev.onliner.by, m.onliner.by, and mail.onliner.by. Plus 2 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of onliner.by contains 4,482 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing. The page is structured with 26 H2 headings, 44 H3 headings, 0 H4 headings. The page includes 160 images. 158 images (99%) 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 1% of images have proper alt text — we recommend adding descriptive alt attributes to all images.
