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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company leverages a technology-driven approach with a Ruby on Rails backend, Cloudflare CDN, and integrations with major advertising and analytics providers. Its competitive advantage lies in simplicity and user experience tailored to presentation sharing. Revenue streams likely include PRO subscriptions and advertising. The target customer segments are professionals and educators who require online presentation hosting. The company maintains a consistent brand and has a mature domain age, indicating stability and trustworthiness.

Security posture

The website enforces HTTPS with a strong SSL configuration and uses CSRF tokens to protect forms. However, it lacks DNSSEC and explicit security headers, which are recommended to enhance security. No incident response or security policy information is publicly available, which could be a gap in transparency and readiness. The presence of multiple third-party tracking and advertising scripts increases the attack surface and privacy considerations. Overall, the security posture is good but could be improved with additional controls and disclosures.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and incident response contact information.
  3. Add a cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Review and minimize third-party tracking scripts to reduce privacy risks and improve performance.

Technical notes

Notes

The website uses a modern technology stack centered on Ruby on Rails, supported by Cloudflare CDN and Amazon CloudFront for hosting and delivery. It integrates multiple advertising and analytics services, including Amazon Ads, BuySellAds, Google Tag Manager, and Facebook Pixel. The site is mobile optimized, accessible, and performs well with fast loading times. The HTML and CSS are valid and SEO optimized with proper meta tags and Open Graph data. There is no detected CMS, indicating a custom or framework-based implementation. Technical risks include reliance on multiple third-party scripts and lack of DNSSEC.
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.
