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 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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Scroll operates in the blockchain technology sector, focusing on Ethereum Layer 2 scalability solutions using zero-knowledge proofs. Their business model revolves around providing open-source infrastructure and developer tools to enable faster and more secure decentralized applications. The company has established partnerships and a community ecosystem, including builder programs and active social media channels. Their competitive advantage lies in combining scalability with uncompromised security, positioning them well in the growing Layer 2 market. Revenue streams likely include developer services, ecosystem support, and possibly token governance. The target customer segments include blockchain developers, startups, and enterprises seeking Ethereum scaling solutions. Growth indicators include over 100 dApps built on their platform and millions of transactions processed.

Security posture

Scroll demonstrates a mature security posture with HTTPS enforced and domain registration protections such as clientTransferProhibited status. However, the absence of DNSSEC and security headers like Content-Security-Policy and X-Frame-Options indicates room for improvement. No explicit incident response or vulnerability disclosure information is found, which could impact responsiveness to security events. Privacy compliance is partial, lacking cookie consent mechanisms and GDPR explicit indicators. No vulnerabilities or exposed sensitive data were detected in the website content. Overall, the security maturity is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner or mechanism to comply with GDPR and improve privacy compliance.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide clear contact information for security incidents and data protection officer details to improve trust and compliance.

Technical notes

Notes

The website is built on a modern tech stack including React and Next.js with Material UI for styling, hosted on Cloudflare infrastructure. It demonstrates fast loading times, mobile responsiveness, and good SEO practices with comprehensive meta tags and Open Graph data. The use of Google Analytics and Tag Manager indicates moderate user tracking. The site is well-structured with clear navigation and professional design. There is no evidence of technical debt or outdated libraries. Opportunities for modernization include enhancing security headers and privacy compliance features. Technical risks are minimal but should be monitored with improved security policies.
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.
