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

Bluelinemedia Limited is a small UK-based technology company specializing in bespoke web design and software development services, operating since 2001. The company targets businesses seeking tailored digital solutions including websites, e-commerce platforms, and integrated software systems. Their market position is that of a trusted local agency with a focus on long-term client relationships and personalized service. Technically, the website employs modern web standards including HTML5, CSS, JavaScript, Google Fonts, and Google Tag Manager for analytics. The site is well-structured with good SEO practices, mobile optimization, and moderate performance. However, no CMS or hosting provider details are explicitly identified. From a security perspective, the site uses HTTPS with good SSL configuration but lacks explicit security headers and public security policies. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is basic with a privacy policy and cookie notice present but no active consent mechanism. Contact information is clearly provided, enhancing business credibility. Overall, the website presents a professional and trustworthy digital presence with strong business legitimacy signals. The absence of WHOIS data is a limitation but likely due to querying the subdomain rather than the root domain. Strategic recommendations include enhancing security headers, adding incident response information, and improving cookie consent mechanisms to strengthen compliance and 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

4 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

  3. 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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Bluelinemedia operates in the bespoke web design and software development sector, serving primarily small to medium-sized businesses in Cheltenham and the wider Gloucestershire area. Their competitive advantage lies in personalized service from an in-house development team, avoiding off-the-shelf solutions. Revenue streams likely include project-based fees for web design, software development, hosting, and ongoing support. The company leverages client testimonials and third-party review platforms like Clutch to build reputation. Their partnership ecosystem includes integrations with payment processors and software platforms (e.g., SagePay, Salesforce). Growth indicators include a 20+ year operational history and a focus on long-term client retention rather than aggressive sales. Strategic observations suggest a stable, locally focused business with potential to expand digital marketing and security transparency.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible sensitive data leaks. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap. No public incident response or security policy documentation is available, which could hinder rapid response to security events. GDPR compliance is partially addressed through a privacy policy and cookie notice, but lack of explicit cookie consent mechanisms and data retention disclosures are weaknesses. The site does not expose vulnerable libraries or insecure forms. Overall, the security posture is adequate for a small business but could be improved with formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  3. Enhance cookie management by adding explicit consent mechanisms compliant with GDPR and ePrivacy Directive requirements.
  4. Conduct an accessibility audit and implement improvements to meet WCAG standards for broader user inclusivity.
  5. Regularly review and update privacy policies and data retention disclosures to maintain compliance with evolving data protection regulations.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS, and JavaScript, utilizing Google Fonts and Google Tag Manager for analytics. The site is well-structured with semantic markup and includes JSON-LD structured data for local business SEO enhancement. Performance is moderate with preconnect and preload hints used for optimization. No CMS or backend platform is explicitly identified, suggesting a custom or static site approach. Hosting provider details are not disclosed. The site is mobile responsive with good navigation clarity. Technical risks are low but could be mitigated further by adopting modern security headers and improving accessibility compliance.
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.
