Medium risk. 7 critical or high findings in Security headers and GDPR outside view.

Security score

63/100

Risk levelMedium

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

Onninen Oy is a large technical wholesale company specializing in HEPAC, electrical, refrigeration, and energy products. It serves contractors, industry, infrastructure builders, and retail dealers primarily in Finland and several other European countries through a network of physical stores and electronic channels. The company is part of the K Group, a significant player in building and technical trade with substantial international presence. Technically, the website is built using modern frontend technologies such as React and Next.js and uses Google Tag Manager for analytics. However, the website suffers from a lack of a valid SSL certificate, resulting in no HTTPS support, which is a critical security flaw. The site also lacks privacy and cookie policies, security headers, and other best practices, which impacts its security posture and privacy compliance negatively. Performance is slow, but mobile optimization and content quality are good, with clear business information and consistent branding. Overall, the website is functional but requires urgent improvements in security and privacy compliance to meet modern standards.

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. 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.

Technical appendix

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

Business context

Business profile

Onninen holds a strong market position as a reliable wholesale distributor in the energy and technical products sector, supported by a large network of stores and integration with the K Group. Its business model focuses on serving professional customers with a comprehensive product range and efficient logistics. The company targets contractors, industry professionals, and retail dealers across multiple European countries, indicating a broad geographic footprint. The lack of visible certifications or trust indicators on the website suggests an opportunity to enhance credibility. The partnership with K Group provides financial strength and market reach. The website content is professionally presented but lacks direct contact information and legal policies, which could affect customer trust and regulatory compliance.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL certificate and HTTPS support, exposing users to potential interception and data integrity risks. The lack of security headers and modern TLS protocols further exacerbates vulnerabilities. No privacy or cookie policies are present, indicating poor privacy compliance. No incident response or security policy information is available, which suggests limited transparency and preparedness. While no active vulnerabilities like Heartbleed or POODLE were detected, the fundamental security configuration is insufficient for a professional business website. Immediate remediation is necessary to protect user data and comply with regulations such as GDPR.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms.
  3. Add standard security headers (CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy) to enhance protection.
  4. Provide clear contact information including emails and phone numbers for customer support and security incident reporting.
  5. Establish and disclose a security policy and incident response process to improve transparency and trust.
Technical notes

Notes

The website uses a modern React and Next.js frontend framework, indicating a contemporary technology stack. Hosting is managed via Cloudflare DNS, but no Cloudflare security features (like SSL or WAF) appear active. Performance is suboptimal with a load time exceeding 7 seconds, which could be improved by optimizing resources and server response times. Mobile optimization is good with responsive images and layout. SEO is supported by meta tags and Open Graph image but lacks structured data. No CMS or backend platform is explicitly detected. The absence of security best practices and valid SSL is a critical technical risk. Overall, the infrastructure is modern but requires urgent security and performance enhancements.
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.
