South London Gallery · Non-profit · United Kingdom

Low risk. 1 critical or high finding in SSL/TLS.

Security score

81/100

Risk levelLow

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

South London Gallery is a well-established non-profit cultural institution in London, providing free access to contemporary art exhibitions, film, performance events, and educational programs for diverse audiences including children and adults. The gallery has a strong community focus and a history spanning over 125 years, positioning it as a key player in the local and broader art scene. The website reflects this with rich content, clear navigation, and consistent branding. Technically, the site is built on WordPress with modern JavaScript libraries and integrates Google Analytics, Tag Manager, and Klaviyo for marketing and analytics. Security measures include HTTPS and Google reCAPTCHA, though some security headers are not explicitly detected. Privacy and cookie policies are comprehensive and GDPR compliant, with active consent mechanisms. The absence of WHOIS data limits domain trust verification but does not detract significantly from the overall legitimacy given the institution's public presence and external references.

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

1 finding 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

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

The South London Gallery operates as a non-profit entity focused on arts and education, targeting a broad audience from local communities to art enthusiasts. Its business model relies on public funding, donations, and community engagement rather than commercial sales. The gallery's partnerships with Arts Council England, Southwark Council, and foundations like Bukhman Foundation reinforce its credibility and funding stability. The website supports this ecosystem with event listings, educational outreach, and a curated shop. The gallery's digital presence is professional and supports its mission effectively, with active social media channels and a newsletter subscription to maintain audience engagement.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from enhanced security headers, regular security audits, and a public-facing vulnerability disclosure or incident response page to improve transparency and readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security policy and incident response information to improve transparency and preparedness.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Ensure all WordPress core, themes, and plugins are regularly updated to mitigate vulnerabilities.
  5. Consider adding direct verified contact emails and phone numbers for improved business credibility and user trust.

Technical notes

Notes

The website is built on a modern WordPress platform with a well-structured theme and uses a variety of JavaScript libraries and services including jQuery, RequireJS, Google Tag Manager, Google Analytics, Klaviyo, and Google reCAPTCHA. The site loads multiple fonts from Google Fonts and Typekit, and uses CSS frameworks like Bootstrap Datepicker and Slick Carousel for UI components. Performance is moderate with asynchronous loading of scripts and preconnect hints for fonts. Accessibility features such as skip links and ARIA labels are present, and SEO is enhanced by Yoast SEO plugin with proper meta tags and structured data in JSON-LD format. The site is mobile optimized and visually consistent with professional design quality.
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.
