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

5 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. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

NEXTENDWEB LTD. operates in the technology sector, focusing on WordPress and Joomla plugin development. Their flagship product, Smart Slider 3, enjoys a large user base and is positioned as a leading slider plugin. The business model appears to be freemium with paid upgrades, targeting website owners and developers. The company maintains active social media channels and uses affiliate marketing networks such as Impact Radius. The domain age and registration details align with the company's history, supporting legitimacy. There is no evidence of subsidiaries or parent companies beyond NEXTENDWEB LTD. The company benefits from strong SEO optimization and a professional online presence, indicating a mature digital marketing strategy.

Security posture

The website enforces HTTPS and includes several security headers, contributing to a solid security baseline. The domain is registered with Cloudflare and has clientTransferProhibited status, reducing risk of unauthorized domain transfers. However, DNSSEC is not enabled, which is a recommended enhancement for DNS security. No security.txt or vulnerability disclosure documents are published, and no incident response contacts are visible, which limits transparency in security incident handling. No exposed sensitive data or vulnerable libraries were detected in the provided content. Privacy policies and cookie consent mechanisms are absent, representing compliance gaps. Overall, the security posture is good but could be improved with enhanced DNS security and published security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Publish comprehensive privacy and cookie policies including GDPR compliance details.
  3. Implement a cookie consent mechanism to comply with privacy regulations.
  4. Create and publish a security policy and incident response contact information to improve transparency and trust.
  5. Add a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.

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.
