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 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
    • 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

Sinch operates in the technology and telecommunications sectors, targeting enterprise and medium to large businesses requiring robust messaging solutions. Their business model is B2B SaaS, offering APIs and integrated messaging platforms. The rebranding of MessageMedia to Sinch Engage consolidates their market presence and streamlines branding. The company leverages partnerships with CRM and e-commerce platforms to enhance value. Growth indicators include extensive integrations, 24/7 support, and a large volume of message delivery. The website content and structure support lead generation and customer engagement effectively.

Security posture

The website employs HTTPS with a valid SSL certificate and domain transfer protection, indicating a secure baseline. However, the absence of DNSSEC and some recommended security headers like Content-Security-Policy and X-Content-Type-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the content. Incident response and security policy information are not prominently published, which could enhance transparency. Overall, the security posture is mature but could benefit from additional hardening and published security governance details.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement and enforce Content-Security-Policy and other security headers to mitigate XSS and clickjacking risks.
  3. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.
  5. Enhance privacy compliance disclosures with detailed data retention and processing information.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO and WP Rocket for SEO and performance optimization. It uses modern web fonts and SVG icons for visual quality and responsiveness. Hosting is on AWS, inferred from DNS nameservers, providing scalable and reliable infrastructure. The site is mobile-optimized with responsive design and good accessibility practices. Performance is enhanced by lazy loading and script deferral. Technical debt appears low, but security header implementation and DNSSEC absence are notable technical gaps. Overall, the technical infrastructure supports a fast, secure, and user-friendly experience.
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.
