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

Blumin is an award-winning full service design agency operating primarily in Cornwall, Manchester, and Cheshire, UK. They specialize in branding, website design and development, bespoke web software, and marketing strategies aimed at launching, growing, and transforming businesses. Their market position is strong regionally with a focus on integrating brand and digital services to deliver comprehensive solutions. The website is professionally designed with excellent content quality and clear navigation, targeting business clients seeking digital and branding services. Technically, the website leverages modern web technologies including Webflow CMS, Google Tag Manager, Microsoft Clarity, LinkedIn Insight Tag, and Sentry for error monitoring. The site is hosted on Webflow's CDN, ensuring fast performance and mobile optimization. Privacy compliance is well addressed with a cookie consent mechanism and a comprehensive privacy policy. However, explicit security headers are not detected in the HTML, which could be improved. Security posture is good with HTTPS enforced and no exposed sensitive data, but the absence of security headers and incident response information suggests room for enhancement. The WHOIS lookup failed due to a domain registration error indicating the domain name contravenes Nominet UK naming rules, which is unusual and reduces trust slightly. Despite this, the website content and business information appear legitimate and professional. Overall, the website presents a low risk with strong business credibility and technical maturity. Strategic recommendations include implementing security headers, publishing incident response and security policies, and resolving domain registration inconsistencies to enhance trust and compliance.

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. 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

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

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

Blumin operates as a medium-sized design agency with a clear regional focus in the UK, serving sectors including technology, marketing, and software development. Their business model centers on providing integrated brand and digital services, including bespoke software solutions and marketing strategies. The company demonstrates competitive advantages through award recognition, a strong portfolio, and a comprehensive service offering. Revenue streams likely include project-based fees for branding, web development, software, and marketing consultancy. The target customer segments are businesses in Cornwall, Manchester, and Cheshire seeking digital transformation and brand growth. Growth indicators include a diverse portfolio and active marketing presence. The partnership ecosystem includes technology providers like Webflow and marketing platforms such as Google and LinkedIn. Operationally, the company maintains multiple physical offices and a professional online presence.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible exposure of sensitive data. The presence of cookie consent with opt-in and preference management aligns with GDPR compliance. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap that could be addressed to enhance protection against common web attacks. No incident response or security policy pages are found, which limits transparency and preparedness communication. The WHOIS domain registration irregularity is a concern but does not directly impact website security. Overall, the security culture appears professional but could benefit from formalizing policies and improving technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish clear security and incident response policies on the website to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  4. Resolve domain registration inconsistencies or clarify domain ownership to enhance trustworthiness.
  5. Enhance visibility of data protection officer or privacy contact information to support GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack primarily using Webflow CMS, supported by JavaScript libraries such as jQuery and integrations with Google Tag Manager, Microsoft Clarity, LinkedIn Insight Tag, and Sentry for analytics and error monitoring. Hosting is provided by Webflow's CDN, ensuring fast load times and excellent mobile responsiveness. The site includes advanced features like video backgrounds and dynamic content sliders. SEO is supported by proper meta tags and structured data in JSON-LD format. Accessibility is good, though further improvements could be made. The technical infrastructure is robust with minimal technical debt visible, but security header implementation is lacking. Overall, the technical setup supports a high-quality user experience and business operations effectively.
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.
