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

Nelio Software operates a mature and professionally maintained website offering a native A/B testing and conversion optimization service specifically designed for WordPress users. The company holds a reputable position in the WordPress ecosystem, evidenced by its WordPress VIP Technology Partner status and comprehensive service offerings including heatmaps, popups, and analytics. The website demonstrates excellent content quality, clear navigation, and strong branding consistency, targeting marketers, eCommerce businesses, publishers, and agencies seeking to optimize their WordPress sites. Technically, the site is built on WordPress with modern plugins and integrations such as Yoast SEO, Nelio A/B Testing, and Nelio Popups. Hosting is provided by SiteGround, and the site employs standard web technologies including jQuery and Google Tag Manager. While performance and mobile optimization are good, the SSL certificate is expired, and security best practices like HSTS and DNSSEC are not implemented, which lowers the overall security posture. Security-wise, the site uses HTTPS with TLS 1.3 and 1.2 protocols and shows no signs of known SSL vulnerabilities or exposed sensitive data. However, the expired SSL certificate and lack of domain protection mechanisms present risks that should be addressed promptly. Privacy compliance is strong, with clear privacy and cookie policies and consent mechanisms in place, aligning with GDPR requirements. Overall, the website is trustworthy and professional but requires immediate attention to SSL certificate renewal and enhanced domain security measures to maintain its credibility and protect user data. Strategic improvements in security headers and domain protection will further strengthen its security posture and business reputation.

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

7 findings rated critical or high. Fix these first.

  1. 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

      Invalid SSL Certificate

      SSL certificate is expired or not yet valid

      What to do: Renew SSL certificate immediately

      • ASVS V12.2.2
      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 · found on this site
  • 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

Nelio Software is positioned as a specialized technology provider in the WordPress plugin market, focusing on conversion optimization through A/B testing and related tools. Its subscription-based SaaS model targets a diverse audience including personal site owners, business owners, marketers, and agencies. The company leverages partnerships such as WordPress VIP to enhance credibility and market reach. The presence of multiple customer testimonials and detailed documentation supports customer trust and engagement. Marketing efforts include affiliate programs and promotional popups, indicating an active growth and customer acquisition strategy. The company’s digital presence is well-integrated with social media and content marketing, supporting brand awareness and customer support.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced with modern TLS versions, and no critical SSL vulnerabilities are detected. However, the expired SSL certificate is a significant security risk that undermines user trust and data protection. The absence of HSTS, OCSP stapling, and DNSSEC reduces the robustness of the security posture. No explicit security policies or incident response contacts are found on the site, which could be improved to enhance transparency and readiness. The site does not expose sensitive data or use vulnerable libraries, and forms appear secure with standard validation. Overall, while basic security practices are in place, critical improvements are needed to meet higher security standards and compliance requirements.

Recommendations

  1. Renew and maintain a valid SSL/TLS certificate to ensure secure encrypted connections.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options to prevent protocol downgrade attacks.
  3. Implement DNSSEC to protect against DNS spoofing and improve domain security.
  4. Activate domain protection locks to prevent unauthorized domain transfers.
  5. Publish a clear security policy and incident response contact information to improve transparency and trust.
Technical notes

Notes

The website is built on a modern WordPress platform using a combination of popular plugins such as Yoast SEO, Nelio A/B Testing, Nelio Popups, and Relevanssi Live Search. It integrates Google Tag Manager and Google Maps API for analytics and mapping functionalities. Hosting is provided by SiteGround, a reputable hosting provider. The site uses modern TLS protocols (1.3 and 1.2) but suffers from an expired SSL certificate, which is a critical technical debt. Performance metrics are moderate with no explicit load time data but the presence of lazy loading and responsive design indicates optimization efforts. Accessibility and SEO are well addressed through semantic HTML, ARIA roles, and Yoast SEO integration. The site uses multilingual support via MultilingualPress. Overall, the technical infrastructure is solid but requires attention to SSL management and enhanced security configurations.
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.
