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

3 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 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 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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Slides.com operates in the competitive online presentation software market, differentiating itself through AI integration and open-source presentation formats for developers. Its freemium business model supports growth via individual users and teams, with clear pathways for upselling through premium features. The company maintains a strong brand presence with consistent messaging and trust signals such as testimonials and partnerships with OpenAI. The ecosystem includes support resources, developer documentation, and active social media engagement. While no direct contact emails or phone numbers are publicly listed, the company provides extensive online support and security information, indicating a mature operational structure.

Security posture

The website exhibits a mature security posture with HTTPS enforced and standard security headers likely implemented. The domain is locked against unauthorized changes, enhancing domain security. Cookie consent is actively managed, supporting privacy compliance. However, the absence of DNSSEC and a published security.txt file or explicit incident response contacts represents areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is good but could be enhanced by formalizing vulnerability disclosure and incident response mechanisms.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information (e.g., security@ or abuse@ emails).
  4. Consider obtaining and displaying recognized security certifications to boost trust.
  5. Maintain and regularly update privacy and security policies to reflect evolving compliance requirements.

Technical notes

Notes

Slides.com uses a modern technology stack with HTML5, CSS3, and JavaScript, enhanced by Google Fonts and Google Analytics for tracking. The site is hosted on AWS infrastructure, as indicated by DNS nameservers. The website is well-optimized for performance and mobile responsiveness, with good SEO and accessibility practices. No CMS was detected, suggesting a custom-built or proprietary platform. The site uses deferred JavaScript loading and preconnect hints to optimize resource loading. Technical risks are minimal, but enabling DNSSEC and formalizing security disclosures would reduce potential attack vectors.
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.
