nationalacademies.org

We performed a comprehensive analysis of nationalacademies.org on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 32809ms. The page is served over HTTP/1.1 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 392 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 1.2 with the ECDHE-RSA-AES128-GCM-SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 7 domain(s) (Subject Alternative Names) and expires on 2026-10-11, which is 104 days from now. The security headers analysis reveals a score of 65/100 (moderate). The following security headers are properly configured: Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Content-Security-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 2 technologies across 2 categories powering nationalacademies.org. The detected stack includes Google Analytics 4 and Google Tag Manager. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, nationalacademies.org receives an overall trust score of 84/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, nationalacademies.org receives a trust score of 84/100, 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 DigiCert Inc with 104 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none policy, DKIM (DomainKeys Identified Mail) providing cryptographic email verification, DNSSEC providing authenticated DNS responses, and a well-established domain registered for over 27.4 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 and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked nationalacademies.org 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 Network Solutions, LLC based in US, with a registration date of 1999-01-29 and expiration date of 2027-01-29.

nationalacademies.org delivers its homepage in 32809ms (server response time), which is considered slow by industry standards. The total page weight is 392 KB, and we detected 332 resource requests loading assets from 18 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 nationalacademies.org. 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 3 JavaScript files are minified. Minifying the remaining 4 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 nationalacademies.org produces approximately 0.19g 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. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 392 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for nationalacademies.org. 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.

nationalacademies.org resolves to the IPv4 address 144.171.1.16, 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 6 name servers: a1-44.akam.net, a11-64.akam.net, a16-67.akam.net, a28-67.akam.net, a5-65.akam.net, and a6-66.akam.net. Having 6 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 nationalacademies.org is handled by Microsoft 365 with 1 MX records configured: nas-edu.mail.protection.outlook.com. 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 none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM (DomainKeys Identified Mail) is configured, adding a cryptographic signature to outgoing emails that receiving servers can verify to confirm the email hasn't been tampered with in transit. DNSSEC is enabled for nationalacademies.org, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites. The domain is registered through Network Solutions, LLC (US). It was first registered on 1999-01-29 and is set to expire on 2027-01-29, making it 27.4 years old. Our subdomain enumeration scan discovered 3 active subdomains for nationalacademies.org: portal.nationalacademies.org, store.nationalacademies.org, and www.nationalacademies.org. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
