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

8 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 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. GDPR outside view

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

    • 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Nosto operates in the technology and e-commerce sectors, providing AI-driven SaaS solutions to enhance online commerce experiences. The business model is B2B, focusing on delivering personalization and merchandising tools to e-commerce platforms. The company maintains a consistent brand presence with active social media channels on Facebook, Twitter, and LinkedIn. The website content and structured data indicate a medium-sized enterprise with a strong market position in intelligent commerce solutions. While direct contact emails and phone numbers are not disclosed, the presence of contact forms facilitates lead generation and customer engagement. The lack of explicit privacy and security policies suggests areas for operational improvement, especially in regulatory compliance and customer assurance.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no visible exposure of sensitive data. However, it lacks several security best practices such as security headers (CSP, HSTS, X-Frame-Options) and published security or incident response policies. No vulnerability disclosures or security.txt files are present, which could enhance transparency and trust. The use of third-party marketing and analytics tools introduces moderate user tracking, but no critical vulnerabilities or malware indicators were detected. To strengthen security maturity, the company should implement comprehensive security headers, publish privacy and incident response policies, and consider a vulnerability disclosure program.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  3. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ emails) to improve transparency and readiness.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance contact information availability by including verified company emails and phone numbers to improve business credibility and user trust.

Technical notes

Notes

The website is built on WordPress CMS, utilizing modern front-end technologies including Swiper.js for carousels, Typekit and Google Fonts for typography, and Marketo Forms for lead capture. Google Tag Manager is used for analytics and marketing tag management. The site is well-optimized for mobile devices and SEO, with proper meta tags and structured data (JSON-LD) implemented. Performance is moderate, with asynchronous loading of scripts to improve page load times. However, the hosting provider is not explicitly identified, and there is room for improvement in security headers and privacy compliance. Overall, the technical infrastructure supports a professional and scalable e-commerce platform presence.
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.
