book.vnmath.com

The domain book.vnmath.com is a potential concern, with a trust score of 53 and a verdict of "Caution Advised". This suggests that users may need to exercise caution when interacting with the website. The domain's performance is also lacking, with a slow response time of 38,464 milliseconds. However, the website's security features are minimal, with a security score of 0.

The trust score of 53 is a cause for concern, as it indicates a moderate level of risk. The verdict of "Caution Advised" reinforces this notion. Furthermore, the absence of essential security features such as SPF and DMARC protocols adds to the overall trust deficit. It is crucial for users to be aware of these vulnerabilities and take necessary precautions.

The technology stack used by book.vnmath.com is a mix of modern and outdated tools. Shopify, Google Analytics 4, and Font Awesome are modern technologies, while jQuery is an older, less secure library. The presence of Shopify and Cloudflare suggests that the website may have some level of scalability and security, but the use of older technologies like jQuery is a concern. The lack of modern security features and the use of older technologies make it an attractive target for potential attackers.

book.vnmath.com delivers its homepage in 38464ms (server response time), which is considered slow by industry standards. The total page weight is 491 KB, and we detected 304 resource requests loading assets from 20 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: 2 out of 73 CSS files and 17 out of 47 JavaScript files are minified. Minifying the remaining 101 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 book.vnmath.com produces approximately 0.24g of CO₂, earning a carbon rating of B. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery.

The infrastructure of book.vnmath.com is subpar, with a response time of 38,464 milliseconds. This is an indication of poor server performance, which can lead to user frustration and a negative experience.

The lack of clear information on the website's registry and MX records further compounds the issue.
