Risk levelMedium

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 a domain age of 5 years indicating a mature registration. However, the website content is minimal and primarily consists of obfuscated JavaScript code without visible business information, metadata, or user-facing content. The technical infrastructure is hosted on Google Cloud DNS but lacks a valid SSL certificate, resulting in no HTTPS support and poor security posture. No privacy, cookie, or terms of service policies are present, and no contact or social media information is available. Overall, the site appears incomplete or under development, limiting its usability and trustworthiness. From a security perspective, the absence of HTTPS, security headers, and DNS security features exposes the site to potential risks. The WHOIS data is consistent and legitimate, but the lack of domain protection locks is a minor concern. Performance is moderate but could be improved with better optimization and content delivery. Strategically, the site requires urgent implementation of SSL/TLS, security best practices, and visible business content to improve credibility and compliance. Without these improvements, the site risks poor user trust and potential security vulnerabilities.

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

7 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 recognized technology company, likely operating in the digital marketing or SEO sector given the domain name. The domain registration aligns with the company's profile, but the website lacks any visible business model, services, or market positioning information. There are no indications of partnerships, subsidiaries, or revenue streams from the site content. The absence of contact details and policies suggests the website is either under construction or not intended for direct customer engagement. This limits the ability to assess competitive advantages or growth indicators from the current data.

Security posture

The security posture of seoab.io is weak due to the lack of a valid SSL certificate and HTTPS support, absence of security headers, and missing DNS security configurations such as DNSSEC and CAA records. No DMARC or email authentication records are present, increasing the risk of email spoofing. The site does not implement HSTS or OCSP stapling, and session resumption is disabled, which affects SSL performance and security. No incident response or vulnerability disclosure policies are found, indicating low maturity in security governance. These gaps expose the site to man-in-the-middle attacks, phishing risks, and reduced user trust.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Configure DNSSEC and add CAA records to enhance DNS security.
  4. Publish clear privacy, cookie, and terms of service policies to improve compliance and user trust.
  5. Add contact information and business content to establish credibility and facilitate communication.
Technical notes

Notes

The website relies heavily on JavaScript with obfuscated code and minimal HTML content, which may hinder SEO and accessibility. Hosting is via Google Cloud DNS, but no CMS or frameworks are detected. Performance is moderate with a 3.3-second load time and only two resources loaded, indicating a lightweight but incomplete site. The lack of meta tags and structured data reduces SEO effectiveness. No analytics or marketing tools are integrated. The absence of mobile optimization and accessibility features cannot be confirmed due to minimal content. Overall, the technical implementation is basic and requires significant enhancement for production readiness.
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.
