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

The website seoab.io is registered to SEMRUSH INC, a technology company based in Cyprus, with domain registration dating back to 2020. The site content is minimal and primarily consists of embedded JavaScript code without visible user-facing content or metadata such as titles or descriptions. There are no privacy, cookie, or terms of service policies detected, nor any contact information or social media links. The hosting infrastructure uses Google Cloud DNS name servers, but no further hosting or CMS details are evident. Security posture is weak due to lack of visible HTTPS configuration and security headers. No analytics or advertising technologies are detected, and no adult or unsafe content is present. Overall, the site appears to be either under development or serving a specialized technical function without public-facing content.

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

8 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

SEMRUSH INC is a known entity in the technology sector, likely providing SEO or digital marketing related services given the domain and company name. The domain age and registration details are consistent with a legitimate business. However, the lack of visible business information, contact details, or marketing content on the site limits insight into market positioning or business model. No partnerships or subsidiaries are identified from the site content. The minimal content suggests the site may be a technical resource or staging environment rather than a full commercial website.

Security posture

The security posture of the website is currently weak due to absence of HTTPS confirmation, missing security headers, and no evidence of privacy or cookie compliance mechanisms. The domain does not have DNSSEC enabled, which is a minor security gap. No incident response or vulnerability disclosure information is available. The lack of contact information for security or abuse reporting further reduces security readiness. There are no indications of exposed vulnerabilities or malicious content, but the site’s minimal content limits comprehensive security assessment.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure data in transit.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC for the domain to improve DNS security.
  4. Publish clear privacy and cookie policies to comply with GDPR and other regulations.
  5. Provide contact information including security and abuse contacts to improve trust and incident response.

Technical notes

Notes

The website relies heavily on JavaScript with no visible HTML content or metadata, indicating it may be a single-page application or a technical backend interface. Hosting is managed via Google Cloud DNS, suggesting reliable infrastructure. No CMS or frameworks are explicitly detected. Performance, mobile optimization, and accessibility cannot be assessed due to lack of visible content. SEO optimization is minimal or absent given no meta tags or structured data. The technical implementation appears incomplete or in early stages.
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.
