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.

Priority findings

4 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. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain www.missinglettr.com points to unregistered service webserversloadbalancer-168638673.us-east-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

Missinglettr operates in the technology sector as a SaaS provider focused on social media marketing automation. Its competitive advantage lies in automating tedious social media tasks, enabling users to drive traffic, leads, and engagement through drip campaigns and curated content. The subscription-based business model targets small to medium-sized content creators and marketing teams. The company has built a solid user base of over 30,000 creators and maintains partnerships with recognized platforms such as Product Hunt. The presence of detailed legal pages and multiple marketing integrations indicates a mature operational approach. Growth indicators include active content marketing, email courses, and webinars. The company’s ecosystem includes integrations with major social media platforms and analytics services, supporting a comprehensive marketing strategy.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and CSRF tokens implemented in forms. Cookie consent mechanisms provide user control over tracking cookies, reflecting privacy awareness. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure information is publicly available, which could hinder rapid response to security issues. The WHOIS data is transparent and consistent with the business profile, with no privacy protection that might raise suspicion. Overall, the security culture appears proactive but could benefit from formalized incident response and enhanced header policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  3. Publish a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  4. Enhance accessibility features to improve compliance with standards and user experience for all users.
  5. Maintain transparency by continuing to provide clear privacy and cookie policies and consider periodic security audits to ensure ongoing compliance.

Technical notes

Notes

The website is built on a modern and stable technology stack leveraging jQuery and Bootstrap for UI components, with extensive use of third-party analytics and marketing scripts such as Google Analytics, Facebook Pixel, Hotjar, and FullStory. Hosting is managed via Cloudflare DNS and CDN, providing performance and security benefits. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Forms use CSRF tokens for security. However, the site lacks some advanced security headers and DNSSEC is not enabled. Performance is moderate, with room for optimization in script loading and accessibility improvements. The technical infrastructure supports the business goals effectively but could be modernized further to enhance security and user experience.
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.
