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

2 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. 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 a SaaS business model targeting SMBs across Europe, focusing on HR process digitization and automation. Their competitive advantage lies in an integrated platform that covers multiple HR functions, strong compliance with European data protection laws, and a growing user base exceeding one million people. Revenue streams likely include subscription fees and premium service tiers. The company maintains a professional partnership ecosystem and invests in marketing and analytics tools to optimize customer acquisition and retention. Growth indicators include multi-language website support and continuous A/B testing for optimization. Strategic observations suggest Personio is well-positioned to expand further into European markets and potentially beyond, leveraging its compliance and certification credentials.

Security posture

The security maturity of Personio's website is high, with HTTPS enforced and multiple security headers inferred. The presence of a consent management platform (Usercentrics) and ISO 27001 certification indicates a strong commitment to data protection and privacy. No exposed sensitive data or vulnerable libraries were detected in the website 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. Compliance with GDPR is evident, but additional NIS2 or similar frameworks are not explicitly mentioned. Overall, the security posture is solid but could benefit from enhanced public security documentation and incident response readiness.

Recommendations

  1. Publish a dedicated security policy page detailing security controls and compliance frameworks.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency around data retention policies and user data handling practices.

Technical notes

Notes

Personio's website is built on a modern technology stack featuring Next.js and React, ensuring fast and responsive user experiences. The use of a CDN (Amazon Cloudfront) optimizes content delivery globally. Analytics and marketing tools such as Google Tag Manager, Visual Website Optimizer, and Usercentrics CMP are integrated for performance monitoring and compliance. The website demonstrates excellent mobile optimization and accessibility standards. Technical debt appears minimal with no broken scripts or errors detected. Opportunities for modernization include expanding API integrations and enhancing security automation. Technical risks are low but depend on maintaining up-to-date third-party components and continuous monitoring.
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.
