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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Prevas operates as a B2B service provider in the technology and manufacturing sectors, focusing on product development and engineering solutions. Its market position is that of an established player with a history dating back to 1985. The company targets businesses needing advanced technology services and emphasizes innovation and diverse competencies. The presence of sister sites in neighboring Nordic countries suggests a regional partnership ecosystem. Revenue streams likely derive from consulting and development contracts. The website content and structure support a professional image aimed at attracting skilled professionals and corporate clients. Growth indicators include active job postings and partner network initiatives.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and a cookie consent banner supporting GDPR compliance. However, there is no evidence of advanced security headers such as Content Security Policy or HSTS, nor is there a published security policy or incident response contact information. No vulnerability disclosure or security.txt files were found, indicating limited transparency in security practices. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Google Tag Manager introduces moderate user tracking, which is disclosed via the cookie banner. Overall, the security maturity is adequate for a corporate site but could be enhanced by publishing formal security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan accessible from the website.
  2. Add HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to improve security posture.
  3. Create and publish a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  4. Enhance privacy compliance by providing a dedicated privacy policy page with detailed GDPR information beyond cookie usage.
  5. Include more explicit contact information such as phone numbers and physical addresses to improve business credibility and user trust.

Technical notes

Notes

The website is built on the SiteVision CMS platform, leveraging jQuery and Slick Carousel for UI components and animations. Google Tag Manager is used for analytics and tracking, indicating a moderate level of digital maturity. The site is mobile responsive and uses modern web fonts and icons. Performance is moderate, with some preloading of scripts and stylesheets to optimize loading times. Accessibility features are basic but present. SEO is supported by canonical tags and meta tags, though keywords meta tag is empty. There is no evidence of server-side frameworks or advanced JavaScript frameworks. The technical stack is stable but could benefit from modernization 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.
