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

3 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.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. 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

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

Personio operates as an essential entity in the HR technology sector, targeting SMEs and medium-sized enterprises with a SaaS business model. Their competitive advantage lies in offering an all-in-one HR platform that automates workflows and integrates multiple HR functions. The company has a strong presence in Switzerland and the broader DACH region, supported by multiple localized domains. Revenue streams likely include subscription fees for software licenses and professional services. Partnerships with integration marketplaces and educational platforms enhance their ecosystem. Growth indicators include multilingual support, ISO certification, and a comprehensive product suite. The company maintains a professional online presence with clear business information and customer engagement channels.

Security posture

Personio demonstrates a mature security posture with HTTPS enforced site-wide, robust security headers, and ISO 27001 certification. The use of a consent management platform ensures GDPR compliance and user privacy. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly accessible security policy or incident response contact limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file. Overall, the security culture appears strong but could benefit from enhanced public communication of security practices and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and practices.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built on a modern technology stack including Next.js and React, hosted on Vercel, which supports fast loading times and excellent mobile responsiveness. The use of WebP images and Lottie animations enhances visual appeal without compromising performance. Consent management is handled via Usercentrics, integrating well with analytics and marketing tools like Google Tag Manager and Visual Website Optimizer. The site structure is well-organized with semantic HTML and SEO-friendly meta tags. Technical risks are minimal, with no detected deprecated or vulnerable libraries. Opportunities exist to further improve accessibility and publish more detailed technical and security documentation.
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.
