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

Symbiosys Business Solutions Ltd operates the SATbill platform, a specialized satellite airtime billing solution designed for satellite service providers and operators worldwide. The company offers a comprehensive software product that supports billing for multiple providers, call types, and value-added services, with strong customization and integration capabilities. Their market position is supported by a global client base, multi-entity billing features, and significant invoicing volume, positioning them as a key player in the satellite telecommunications billing niche. Technically, the website is built on the HubSpot CMS platform, leveraging modern web technologies including Google Fonts, jQuery, and various analytics and marketing tools such as Google Analytics, Hotjar, and LinkedIn Insight. The site is well-optimized for mobile and accessibility, with good SEO practices and a professional design that enhances user experience. From a security perspective, the site enforces HTTPS, uses reCAPTCHA on forms, and benefits from HubSpot's security headers and infrastructure. However, the absence of explicit security policy pages and vulnerability disclosure mechanisms suggests room for improvement in transparency and incident response readiness. The WHOIS data is missing or indicates the domain may not be registered, which raises concerns about domain legitimacy despite the professional website content. Overall, the website presents a trustworthy and professional front for a specialized business solution, but the lack of WHOIS registration data and explicit security policies slightly reduce the overall trust score. Strategic recommendations include establishing clear security and incident response documentation, verifying domain registration, and enhancing transparency to strengthen stakeholder confidence.

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.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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.

Business context

Business profile

Symbiosys Business Solutions Ltd targets satellite service providers and operators with its SATbill billing software, offering a robust solution capable of handling complex billing scenarios involving multiple providers and services. Their business model combines software licensing with professional services such as customization, implementation, and support, enabling recurring revenue streams. The company demonstrates competitive advantages through extensive CDR format support, multi-entity billing, and API integrations. Testimonials and case studies indicate strong customer satisfaction and operational efficiency gains. The company operates primarily in the telecommunications sector with a medium-sized footprint based in the UK, serving clients across multiple countries. Partnerships with technology providers and a strong digital presence support their market reach and growth potential.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of reCAPTCHA v2 on forms, and deployment on a reputable CMS platform (HubSpot) that provides standard security headers and protections. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of dedicated security policy pages, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in security transparency and readiness. The missing WHOIS registration data is a notable concern for domain legitimacy and trust. Overall, the security posture is good but could be enhanced by publishing explicit security documentation and implementing DNSSEC.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Implement and publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  3. Verify and update WHOIS registration data to ensure domain legitimacy and stakeholder trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance form security by upgrading to the latest reCAPTCHA version or alternative anti-bot solutions.

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.
