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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Welltec operates in the energy sector with a focus on innovative solutions for well completion and intervention, as well as new energy technologies. Their business model is B2B, serving oil and gas companies and energy producers. The company leverages partnerships and third-party services for marketing and analytics, including LinkedIn, Facebook, Google Marketing Platform, and Sleeknote. The website content and structure suggest a mature market position with a focus on sustainability and operational efficiency. The lack of visible direct contact information and WHOIS transparency may impact customer trust and due diligence processes. The company appears to maintain a solid digital presence with room for enhanced security and compliance disclosures.

Security posture

The website enforces HTTPS and uses Cloudflare for CDN and security. Cookie consent is implemented with detailed categories and links to privacy policies of third-party services, indicating good GDPR compliance. However, the site lacks explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are recommended best practices. No security policy, incident response contacts, or vulnerability disclosure mechanisms are found, limiting transparency in security governance. No exposed sensitive data or vulnerable libraries are detected in the HTML content. Overall, the security posture is good but could be strengthened by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add HTTP security headers including Content Security Policy (CSP), HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Provide explicit contact emails and phone numbers for customer support and security inquiries to improve trust and accessibility.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Verify and update domain WHOIS information to improve transparency and domain legitimacy perception.

  2. Comprehensive cookie consent banner with detailed cookie categories
  3. No visible contact emails or phone numbers on main pages; contact via form only
  4. No explicit terms of service or security policy pages found
  5. No security.txt or vulnerability disclosure information present
  6. WHOIS data unavailable, raising some concerns about domain registration transparency
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.
