Security report for ahrefs.dev

403 Forbidden · Other · N/a

Medium risk. 6 critical or high findings in Security headers and GDPR outside view.

Security score

54/100

Risk levelMedium

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

The website ahrefs.dev is currently inaccessible, returning a 403 Forbidden error page served by nginx behind Cloudflare. This indicates that access is blocked or restricted, likely due to security configurations or firewall rules. Due to the lack of accessible content, no business information, metadata, or contact details can be extracted. The technical infrastructure shows DNS hosted on Cloudflare with valid SPF records but no DNSSEC or CAA records. The SSL/TLS configuration is absent or invalid, with no HTTPS support and no modern TLS protocols enabled. Security headers and best practices are missing, resulting in a low security posture. Overall, the site is effectively blocked from analysis, limiting the ability to assess business credibility, privacy compliance, or content quality.

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

6 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 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. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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.

Add-on

Leaked records that mention ahrefs.dev, from OffSeq Breach.

No leaked records found

Breach holds no records for ahrefs.dev right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

No business intelligence can be derived from the site due to the lack of accessible content and metadata. The domain is registered but WHOIS data is unavailable or privacy protected, preventing verification of registrant legitimacy or business claims. No information about market positioning, services, or partnerships is available. The site appears to be in a restricted or maintenance state, or protected by Cloudflare security policies.

Security posture

The security posture is poor with no valid SSL certificate, no HTTPS enabled, and no security headers detected. The site is served behind Cloudflare, which provides some protection, but the absence of TLS and security best practices exposes the site to risks if accessed directly. No incident response or vulnerability disclosure information is available. The SPF record is valid, which is a positive indicator for email security. Overall, the site requires urgent improvements in SSL/TLS configuration and security header implementation.

Recommendations

  1. Install and configure a valid SSL/TLS certificate to enable HTTPS and secure communications.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure protocols.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Enable HSTS with includeSubDomains and preload options to enforce HTTPS.
  5. Review Cloudflare firewall and access rules to allow legitimate traffic and reduce false positives.
Technical notes

Notes

The site uses Cloudflare for DNS and hosting protection but lacks a valid SSL certificate and does not support HTTPS protocols. DNSSEC and CAA records are not enabled, reducing DNS security. The site returns a 403 Forbidden error with minimal HTML content, indicating restricted access. Performance is poor with a high load time and minimal resources loaded. No CMS, frameworks, or analytics technologies are detectable due to blocked content. The technical infrastructure requires modernization and proper security configuration to support a functional and secure website.
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.
