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

7 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

DNB operates as a full-service bank with a large customer base in Norway, targeting both private and corporate clients. Its business model revolves around providing a wide array of financial products and services, supported by a strong digital infrastructure. The presence of multiple subsidiaries such as DNB Eiendom and Sbanken indicates a diversified portfolio. The company leverages partnerships for enhanced offerings, as seen with Finansportalen for price comparisons. The website content and structure suggest a focus on customer engagement and service accessibility, with clear calls to action and educational resources. The brand's consistency and trust signals, including physical addresses and regulatory information, reinforce its credibility in the financial sector.

Security posture

The website employs HTTPS with an excellent SSL configuration, ensuring secure data transmission. Security headers are present, and best practices such as secure form inputs and no exposure of sensitive data are observed. The use of reputable third-party services like Adobe Launch and Dynatrace for analytics and monitoring further enhances security monitoring capabilities. No vulnerabilities or security issues were detected in the analyzed content. However, explicit Content-Security-Policy headers should be verified and enforced to mitigate potential risks. Incident response and security policy documentation are not explicitly found on the site, suggesting an area for improvement in transparency.

Recommendations

  1. Implement and verify explicit Content-Security-Policy headers to enhance protection against XSS and related attacks.
  2. Publish clear security policy and incident response procedures to improve transparency and user trust.
  3. Regularly audit and update third-party scripts and dependencies to prevent vulnerabilities.
  4. Enhance accessibility features to meet or exceed standards for all user groups.
  5. Develop a long-term security strategy focusing on continuous monitoring and compliance with evolving regulations.

Analytics and marketing tools are integrated via Adobe Launch and Dynatrace, indicating a mature digital marketing infrastructure.

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.
