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

The website seoab.io appears to be a technical or internal resource associated with SEMRUSH INC, a technology company registered in Cyprus since 2020. The site content is minimal, consisting primarily of embedded JavaScript code without user-facing content, metadata, or structured data. There are no visible privacy, cookie, or terms of service policies, nor any contact information or social media links. The domain registration is consistent and legitimate, with professional DNS hosting via Google Cloud DNS. However, the lack of visible content and policies limits the ability to fully assess the site’s business and security posture. From a technical perspective, the site uses JavaScript heavily but lacks detectable frameworks or CMS. No security headers or SSL configuration details were found in the provided data, indicating potential gaps in security best practices. No forms or data collection mechanisms were identified, suggesting limited user interaction. The site does not appear to use advertising or analytics services. Security posture is weak due to missing security headers, lack of DNSSEC, and no visible SSL information. Privacy compliance is also lacking with no privacy or cookie policies detected. The domain WHOIS data is transparent and consistent with a legitimate business entity, supporting moderate trust in the domain’s legitimacy. Overall, the site scores low on content quality and security but has a solid domain registration foundation. Recommendations include implementing HTTPS with a valid SSL certificate, adding security headers, publishing privacy and cookie policies, and providing clear contact information to improve trust and compliance. Enhancing visible content and metadata would also improve SEO and user experience.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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 operating in the digital marketing and SEO tools sector. The domain seoab.io is registered under SEMRUSH INC in Cyprus, indicating a legitimate business presence. The website itself lacks public-facing content, suggesting it may serve as an internal tool or a technical endpoint rather than a customer-facing site. No direct business model, revenue streams, or target audience information is discernible from the site content. The absence of marketing or advertising elements further supports this. The company likely targets digital marketing professionals and enterprises needing SEO analytics, but this is not explicitly stated on the site. The domain age of approximately 4 years aligns with a medium-sized technology company lifecycle. No partnerships or subsidiaries are indicated on the site. The lack of contact or trust indicators limits the ability to assess competitive advantages or growth indicators from this domain alone.

Security posture

The security posture of seoab.io is currently weak based on the available data. There is no evidence of HTTPS enforcement or SSL certificate presence, which is a critical security requirement. Security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, increasing risk of common web attacks. DNSSEC is not enabled, which could expose the domain to DNS spoofing risks. No incident response contacts or security policies are published, limiting transparency and preparedness for security events. The site does not appear to collect user data or have forms, reducing attack surface but also limiting user engagement. The WHOIS data is consistent and transparent, which is a positive trust factor. Overall, the site requires significant improvements in security best practices and compliance to reduce risk and enhance trustworthiness.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure all communications.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC for the domain to protect against DNS spoofing.
  4. Publish comprehensive privacy and cookie policies to comply with GDPR and build user trust.
  5. Provide clear contact information including security incident response contacts.
  6. Enhance website content with metadata, Open Graph tags, and structured data for SEO and usability.
  7. Conduct a security audit to identify and remediate any hidden vulnerabilities.
  8. Implement user-friendly navigation and mobile optimization to improve user experience.
  9. Consider adding analytics and monitoring tools with privacy compliance.
  10. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is primarily composed of embedded JavaScript code with no visible HTML content or metadata. The domain uses Google Cloud DNS name servers, indicating professional hosting infrastructure. No CMS or frameworks are detected. The site lacks metadata, Open Graph tags, or JSON-LD structured data, which limits SEO effectiveness. No forms or interactive elements are present. Performance and mobile optimization cannot be assessed from the provided data. Accessibility features are not evident. The absence of security headers and SSL information suggests technical debt in security implementation. The site appears to be a technical or internal resource rather than a public marketing website. Modernization opportunities include adding semantic HTML, metadata, security enhancements, and user engagement features to improve overall digital maturity.
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.
