zaim.net

We performed a comprehensive analysis of zaim.net on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 8801ms. The page is served over HTTP/2 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 34 KB, and the site is served behind a CDN (Content Delivery Network). The website uses a secure HTTPS connection with a valid SSL certificate issued by DigiCert Inc (OV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 3 domain(s) (Subject Alternative Names) and expires on 2027-02-14, which is 229 days from now. The security headers analysis reveals a score of 45/100 (below average). The following security headers are properly configured: X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 2 technologies across 2 categories powering zaim.net. The detected stack includes Google Tag Manager and StackPath. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, zaim.net receives an overall trust score of 73/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, zaim.net 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 DigiCert Inc with 229 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, 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 zaim.net 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.

zaim.net delivers its homepage in 8801ms (server response time), which is considered slow by industry standards. The total page weight is 34 KB, and we detected 94 resource requests loading assets from 9 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 zaim.net. 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 1 CSS files and 0 out of 1 JavaScript files are minified. Minifying the remaining 2 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 zaim.net 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 34 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for zaim.net. 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.

zaim.net resolves to the IPv4 address 18.165.122.120, 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 4 A record(s) configured. The domain name system is managed by 4 name servers: ns-1138.awsdns-14.org, ns-1681.awsdns-18.co.uk, ns-480.awsdns-60.com, and ns-792.awsdns-35.net. 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 zaim.net is handled by Google Workspace with 4 MX records configured: aspmx.l.google.com, alt1.aspmx.l.google.com, and alt2.aspmx.l.google.com and 1 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 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 zaim.net. 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 homepage of zaim.net contains 285 words of visible text content. This is a relatively short page — adding more descriptive content could improve search engine visibility. The page is structured with 7 H2 headings, 14 H3 headings, 0 H4 headings. The page includes 29 images. 9 images (31%) 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 69% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 28 internal links pointing to other pages on the same domain and 27 external links pointing to third-party websites. There are 1 external JavaScript files, 1 CSS stylesheets, and 1 iframes on the page. The site implements the following web standards and features: robots.txt (controls search engine crawling behavior) and Progressive Web App (PWA) manifest (enabling app-like installation). Notable missing features: XML Sitemap and Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility.
