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

10 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

  2. 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"

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

Perille.fi holds a strong market position as Finland's most comprehensive travel ticket service, leveraging partnerships with key transport providers like VR, Matkahuolto, and Finnair. Its business model focuses on aggregating travel options and simplifying ticket purchases, targeting both local and long-distance travelers. The company benefits from a growing ecosystem of partners and a user base that values convenience and sustainability. The platform's multilingual support and widget offerings extend its reach to travel professionals and event organizers. Growth potential lies in expanding local transport options and international travel routes. The company maintains a small size with a focused operational scope, founded in 2015, and emphasizes customer feedback and continuous service improvement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure program indicates room for improvement in transparency and preparedness. Compliance with GDPR is evident through comprehensive privacy and cookie policies with consent mechanisms. The platform should consider publishing explicit security documentation and establishing formal incident response contacts to enhance trust and readiness.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Enhance accessibility features to meet higher standards for all users.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Expand contact information to include direct support emails and phone numbers for improved user trust.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, enabling server-side rendering and efficient client-side interactions. Google Tag Manager is used for analytics and marketing tracking, and Stripe is likely integrated for payment processing. The site is mobile-optimized with responsive design, though accessibility features are basic and could be improved. Performance is moderate, with multiple CSS and JavaScript chunks loaded asynchronously. SEO is supported with proper meta tags and alternate language links. No CMS was detected, suggesting a custom or framework-based solution. Hosting provider details are not explicitly available. Overall, the technical infrastructure supports a robust and scalable user experience with opportunities for further optimization and security 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.
