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

2 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 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Cocolyze operates in the competitive SEO software market, leveraging a subscription-based business model with a free trial to attract users. Their competitive advantage lies in offering a simplified yet advanced SEO analysis platform that integrates multiple SEO functions into a single tool. The company maintains active social media channels and provides educational resources such as SEO courses and a glossary, enhancing customer engagement and market reach. The domain age and registration data align with the company's founding date, supporting credibility. However, no explicit revenue or partnership data is publicly disclosed.

Security posture

The website employs HTTPS and uses reputable DNS and CDN providers like Cloudflare, indicating a baseline secure infrastructure. A cookie consent mechanism and privacy policy compliant with GDPR are present, reflecting good privacy practices. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in security transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. Security headers and DNSSEC are not enabled, which could enhance the security posture further.

Recommendations

  1. Implement and publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  2. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  3. Add security-related HTTP headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to harden the website against common attacks.
  4. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  5. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.

Technical notes

Notes

The website is built with modern JavaScript libraries including jQuery, GSAP, Lottie Player, and Slick Carousel, providing rich interactive features and animations. It uses Cloudflare for DNS and CDN services, enhancing performance and availability. The site is mobile-optimized with responsive design and good SEO metadata including canonical URLs and descriptive meta tags. Performance is moderate, with potential for improvement by optimizing script loading and caching strategies. No CMS was detected, indicating a custom or proprietary platform. Accessibility features are basic but present, with room for enhancement to meet higher standards.
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.
