The company offers a popular slider plugin with over 800,000 users, positioning itself as a leader in the WordPress plugin market. The website is professionally designed, mobile-optimized, and integrates advanced editor tools to help users build sliders effectively.

Technically, the site uses WordPress CMS with integrations such as Yoast SEO Premium, Google Analytics, and Google Tag Manager, hosted with Cloudflare DNS and registrar services.

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.

Business context

Business profile

NEXTENDWEB LTD. has carved a niche in the WordPress ecosystem by providing a highly rated slider plugin, Smart Slider 3. The company leverages a freemium business model, attracting a large user base and generating revenue through premium features. Their target customers are WordPress and Joomla users, including developers and website owners seeking enhanced visual tools. The company maintains active social media channels on Facebook, Twitter, and YouTube, supporting community engagement and marketing. The use of affiliate marketing via Impact Radius indicates a strategic approach to expanding reach. The domain registration and website content are consistent, reflecting a mature and credible business operation. However, the absence of detailed privacy and security policies suggests areas for compliance improvement.

Security posture

The website employs HTTPS with a valid SSL certificate and has domain status set to clientTransferProhibited, which protects against unauthorized domain transfers. However, DNSSEC is not enabled, which is a recommended security enhancement to prevent DNS spoofing. No security headers such as Content-Security-Policy or Strict-Transport-Security were detected, which could improve protection against common web attacks. There is no visible security policy or incident response contact information, limiting transparency in handling security incidents. The integration of third-party analytics and affiliate scripts introduces moderate tracking but no apparent vulnerabilities were found in the provided content. Overall, the security posture is moderate but could be strengthened by implementing recommended headers, DNSSEC, and publishing security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing attacks.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  4. Publish a security policy and provide incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and readiness.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used and maintain secure forms and input handling.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO Premium for SEO optimization and Google Analytics and Tag Manager for analytics and tracking. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and good content quality. However, accessibility features are basic and could be improved. Performance is moderate, likely influenced by multiple external scripts and slider assets. There is no evidence of technical debt or outdated technologies in the provided content. Opportunities exist to enhance security configurations and privacy compliance to align with best practices and regulatory requirements.
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.
