0–100, higher is better. How it is calculated

Sepura Limited is a UK-based company specializing in the design, development, and supply of TETRA and LTE digital radio products and applications for business and mission-critical communications. The company holds a strong market position as a leading provider of TETRA radios with a legacy spanning over 125 years. Their solutions target public safety, energy, transportation, and commercial sectors globally, supported by a large partner network and extensive R&D efforts. Technically, the website is built on WordPress with modern plugins and marketing tools, demonstrating good digital maturity and SEO practices. However, a critical security gap exists due to the absence of a valid SSL/TLS certificate, exposing users to potential risks. Privacy and cookie policies are comprehensive and GDPR compliant, with clear contact information and trust indicators such as certifications and customer testimonials. Overall, the website is professional and trustworthy but requires urgent security improvements to protect user data and enhance trust.

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

5 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 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.

    • 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 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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

Sepura operates in the telecommunications sector with a focus on mission-critical communications. Their business model revolves around providing robust communication devices and solutions for sectors requiring reliable and secure communication, such as public safety and energy. The company leverages a strong R&D team and global partnerships to maintain competitive advantages. Revenue streams likely include product sales, device management services, and application solutions. The website content and structure indicate a mature organization with a clear target audience and a well-established market presence. Strategic partnerships and certifications further reinforce their credibility and growth potential.

Security posture

The current security posture reveals significant weaknesses, primarily the lack of HTTPS, which is a critical vulnerability for any modern website. While the site implements a strict Content Security Policy and restricts unsafe content sources, the absence of SSL/TLS undermines data confidentiality and integrity. No HSTS or OCSP stapling is enabled, and session resumption features are missing. There is no explicit incident response or security policy information available, which could impact readiness for security events. Privacy compliance is well addressed, but the security gaps pose risks to user trust and data protection. Immediate remediation of SSL/TLS and enhancement of security headers is recommended.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate supporting TLS 1.2 or 1.3 to secure all website traffic.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish a dedicated security policy and incident response plan accessible on the website.
  5. Add a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.

Technical notes

Notes

The website is powered by WordPress 6.8.1 with Yoast SEO and HubSpot integration, indicating a modern CMS setup with SEO and marketing capabilities. The use of external libraries such as Animate.css, Flickity, and Plyr enhances user experience with animations, carousels, and video playback. Hosting is on a DigitalOcean IP, suggesting cloud-based infrastructure. Performance metrics are not available, but the site appears mobile-optimized with responsive design. Accessibility is basic but present. The lack of SSL/TLS is a major technical deficiency. Overall, the technical stack is contemporary but requires security hardening and performance monitoring.
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.
