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

Della Valle Architects Ltd is a small, award-winning architectural practice based in Shepton Mallet, Somerset, UK. The company is a RIBA Chartered Practice, indicating a high standard of professional architectural services. Their website showcases a portfolio of residential and commercial projects, emphasizing refurbishment, modernisation, extensions, and new dwellings. The firm targets clients seeking quality architectural design services within the Somerset region and surrounding areas. The business model is focused on providing professional architectural consultancy and design services with a strong emphasis on quality and client service. Technically, the website is built using standard web technologies including jQuery and CSS, with responsive design elements for mobile optimization. The site is well-structured with appropriate meta tags and Open Graph data for SEO and social sharing. However, no advanced CMS or hosting provider details are evident. Performance is moderate, and accessibility is basic but functional. No analytics or tracking scripts were detected, indicating a privacy-conscious approach. From a security perspective, the site uses HTTPS and has no visible exposed sensitive data or vulnerable libraries. However, no security headers were detected, and there is no visible incident response or vulnerability disclosure information. Privacy and cookie policies are present but lack explicit consent mechanisms. The WHOIS data could not be extracted due to a query error related to the domain name format, but the website content and contact information support legitimacy. Overall, the security posture is moderate with room for improvement in headers, policies, and transparency. The overall risk assessment is low, with the main recommendations focusing on enhancing security headers, implementing cookie consent mechanisms, publishing incident response and vulnerability disclosure policies, and improving privacy compliance indicators. These steps will stre…

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

5 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
    • 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';…

  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

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

Della Valle Architects operates in the real estate sector, specifically architectural services, with a strong regional presence in Somerset, UK. Their market positioning is enhanced by RIBA chartered status and recent regional awards, which serve as competitive advantages. The business model is service-oriented, focusing on bespoke architectural design for residential and commercial clients. Revenue streams likely come from project-based fees and consultancy. The target customer segments include homeowners, developers, and commercial property owners seeking architectural expertise. Growth indicators include award recognition and a well-maintained project portfolio. The partnership ecosystem is limited in the public domain, with no explicit partner domains identified. Strategic observations suggest a focus on quality and client service, leveraging professional certifications and local reputation to maintain market position.

Security posture

The current security maturity level is moderate. The website enforces HTTPS, which is mandatory for secure communications. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure policies are published, indicating limited readiness for security incidents. Data protection practices are basic, with privacy and cookie policies present but lacking explicit consent mechanisms. No security contact channels were found, which could hinder timely reporting of security issues. The security culture appears minimal but not negligent, with no visible vulnerabilities or exposed sensitive data. Compliance gaps exist regarding GDPR consent and transparency. Overall, the security posture is adequate for a small professional services website but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web vulnerabilities.
  2. Deploy a cookie consent mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ emails).
  4. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve trust.

Technical notes

Notes

The website uses a traditional tech stack with jQuery and jQuery UI libraries, along with SlickNav for mobile navigation. The HTML structure is valid and includes appropriate meta tags for SEO and social media sharing (Open Graph and Twitter cards). The site is mobile responsive with CSS media queries and uses deferred loading for some JavaScript to improve performance. No modern JavaScript frameworks or CMS platforms are evident, suggesting a custom or legacy CMS. Performance is moderate with room for optimization. Accessibility features are basic, with no ARIA landmarks or advanced accessibility attributes detected. No analytics or tracking scripts were found, indicating minimal data collection. The site lacks advanced security configurations such as security headers and explicit privacy consent mechanisms. Overall, the technical implementation is functional but could benefit from modernization and enhanced security practices.
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.
