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

Nasstar is a UK-based managed IT services and cloud solutions provider, recognized as a Microsoft Partner. The company focuses on helping businesses navigate complex technology landscapes, offering services in data, AI, secure networking, and cloud infrastructure. Their market position is that of a trusted mid-sized technology partner serving business clients seeking next-generation IT solutions. The website reflects a professional and modern digital presence, leveraging advanced web technologies such as Next.js and Vercel hosting, ensuring fast performance and mobile optimization. Privacy and cookie compliance are well implemented, with clear policies and consent mechanisms in place. Security posture is strong with HTTPS and security headers, though explicit security policies and incident response contacts are not publicly detailed. The absence of WHOIS registration data introduces some uncertainty regarding domain legitimacy, but overall the business credibility and trust signals are solid. Strategic recommendations include publishing detailed security policies, incident response contacts, and vulnerability disclosure information to enhance transparency 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

3 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

  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

Nasstar operates in the competitive managed IT and cloud services market in the UK, targeting business customers requiring flexible, secure, and future-proof IT infrastructure. Their business model is B2B service provision with a focus on cloud transformation, AI readiness, and hybrid workforce enablement. The company leverages partnerships such as Microsoft to strengthen market credibility. Revenue streams likely include managed services contracts, cloud hosting, and consulting. The website content and structure indicate a mature digital marketing approach with integrated analytics and marketing tools like Google Tag Manager and Klaviyo. Growth indicators include emphasis on next-generation technologies and flexible workforce solutions. The partnership ecosystem is evident but limited to major technology vendors. Overall, Nasstar presents as a medium-sized, established technology service provider with a clear market niche.

Security posture

Nasstar demonstrates a good security maturity level with enforced HTTPS, comprehensive security headers, and cookie consent management aligned with GDPR. However, the lack of a dedicated security policy page, incident response contact details, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the website content or scripts. The use of modern frameworks and hosting platforms reduces risk exposure. Compliance with GDPR is evident through privacy and cookie policies. The security score is solid but could be enhanced by publishing explicit security governance documents and incident handling procedures. Overall, the security posture supports business continuity and client trust but should evolve to meet higher transparency standards.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance WHOIS transparency or provide domain registration details to improve trust.
  5. Continue to maintain and update privacy and cookie compliance mechanisms.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on Vercel, ensuring fast load times and excellent mobile responsiveness. Integration with Google Tag Manager and Klaviyo indicates advanced marketing and analytics capabilities. The site uses CookiePro for consent management, supporting GDPR compliance. The technical implementation is robust with valid HTML and CSS, security headers, and HTTPS enforced. No CMS was explicitly detected, suggesting a custom or headless approach. Performance is optimized, and accessibility features are present, contributing to a positive user experience. Technical risks are minimal, but ongoing monitoring of third-party scripts and dependencies is recommended to avoid vulnerabilities.
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.
