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

2 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

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

Barclays Investment Bank is positioned as an essential entity within the finance sector, targeting corporate, government, and institutional clients. The business model focuses on delivering investment banking services including strategic advisory, financing, and risk management. The website's content and structure indicate a large enterprise with a global footprint, supported by consistent branding and official social media channels. The absence of public WHOIS data suggests privacy protection, which aligns with industry norms for financial institutions. The site integrates multiple advertising and analytics platforms, indicating a sophisticated marketing and data collection strategy. No direct partnerships or subsidiaries domains were identified from the website content. The company leverages a robust digital infrastructure to maintain market competitiveness and client engagement.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS encryption and implementation of cookie consent compliant with GDPR. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site lacks a published security policy or incident response contact information, which could enhance transparency and trust. No security.txt or vulnerability disclosure mechanisms were found, which are recommended best practices for enterprise websites. Overall, the security maturity is good but could be elevated by adopting additional security headers and publishing formal security documentation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a comprehensive security policy and incident response information on the website to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly review and update third-party scripts and analytics tools to minimize potential security risks.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, utilizing modern front-end technologies such as jQuery and Bootstrap for responsive design. It integrates multiple analytics and marketing tools including Google Tag Manager, Adobe DTM, LinkedIn Insight, and Twitter Analytics, indicating a mature digital marketing infrastructure. The site is mobile optimized with good SEO practices evident from meta tags and structured data. Performance is moderate, with potential for optimization in loading speed. Accessibility is basic but functional. The technical stack is robust for an enterprise financial institution, though opportunities exist to enhance security headers and streamline third-party integrations to reduce technical debt and improve security posture.
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.
