0–100, higher is better. How it is calculated

instant.page is a small technology-focused business providing an open source JavaScript library designed to improve website page load times by preloading pages just before users click on links. The service targets website owners and developers aiming to enhance user experience and conversion rates. The website is professionally designed, mobile-optimized, and features strong trust indicators including endorsements from major brands and a popular GitHub repository. Technically, the site uses modern web standards, asynchronous script loading, and performance best practices, resulting in fast page loads and good accessibility. However, the site lacks formal privacy and cookie policies, and does not provide contact information or security policies, which impacts privacy compliance and security posture scores. Overall, the domain registration data is consistent and trustworthy, supporting the legitimacy of the business.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

10 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the technology sector with a niche focus on web performance optimization. Its open source MIT license model suggests revenue may come from indirect means such as consulting or support rather than direct sales. The presence of logos from well-known companies indicates strong market trust and adoption. The company maintains a GitHub presence with significant community engagement. The lack of detailed business contact information and policies suggests a lean operation focused on developer adoption rather than direct consumer sales. The website content and branding are consistent and professional, supporting a credible market position.

Security posture

The website demonstrates moderate security maturity. It uses HTTPS and script integrity attributes, and loads scripts asynchronously to improve security and performance. However, it lacks visible security headers such as Content-Security-Policy and Strict-Transport-Security, and does not provide a security policy or incident response contact information. No vulnerabilities or exposed sensitive data were detected in the content. The absence of privacy and cookie policies is a compliance gap. Overall, the security posture is adequate but could be improved with formal policies and enhanced HTTP headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve privacy compliance.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information for security incidents and general inquiries.
  4. Add a security.txt file to facilitate vulnerability disclosures.
  5. Regularly review and update analytics and tracking practices to ensure GDPR compliance.

Technical notes

Notes

The website uses modern HTML5 and CSS Grid layouts with responsive design, ensuring good mobile optimization and accessibility. JavaScript is modular and loaded asynchronously with integrity checks, enhancing security and performance. Google Analytics and Tag Manager are used for analytics, indicating moderate user tracking. The site is fast loading and well-structured with clear navigation. No CMS or hosting provider is explicitly detected. The technical implementation is solid with opportunities to improve security headers and privacy disclosures.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
