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. 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

  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

SES Technologies operates in multiple sectors including transport, energy, retail, education, logistics, and office space, offering a range of security and low energy solutions. Their business model focuses on professional services and tailored technology solutions. The company maintains a moderate growth trajectory with a clear market niche. The presence of social media accounts and structured data indicates a degree of digital maturity. However, no certifications or formal security policies are published, which could be areas for future development. The company’s domain age and registration details support its legitimacy and market presence.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism compliant with GDPR. Tracking and analytics scripts are used responsibly, with no exposed sensitive data detected. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates a moderate security maturity level. Security headers beyond SSL are not evident, and accessibility features are basic. No vulnerabilities or suspicious domains were detected in the analysis. Enhancing transparency around security practices and adding formal policies would strengthen the security posture.

Recommendations

  1. Publish a formal security policy page outlining security practices and compliance.
  2. Add an incident response contact or page to improve transparency and readiness.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance security headers such as Content-Security-Policy and X-Content-Type-Options.
  5. Improve website accessibility features to meet higher standards.

Technical notes

Notes

The website is built on the Squarespace platform, utilizing modern web technologies including Typekit fonts, Google Analytics, Bing UET, and FingerprintJS2 for tracking. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, typical for a Squarespace-hosted site. No deprecated or vulnerable libraries were detected. The technical infrastructure is stable and suitable for the company's business needs, though opportunities exist to improve accessibility and security header implementation.
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.
