Security score

49/100

Risk levelHigh

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

Abakus Limited is a UK-based company formerly known as Abakus Scientific, now closed. The website serves as a legacy portal retaining contact information and offering limited sale of previous product designs and stock related to optical lenses and adaptors. The business model has shifted from active operations to liquidation of assets. The website content is minimal and static, targeting a niche audience interested in legacy optical components. Technically, the website is basic HTML with no modern frameworks or CMS detected, lacking mobile optimization and accessibility features. Security posture is weak with no evidence of HTTPS or security headers, and no privacy or cookie policies are present. WHOIS data is unavailable due to domain naming rules violation, which raises concerns about domain registration legitimacy. Overall, the website is functional but minimal, with significant room for improvement in security 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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 company operated in the technology sector specializing in optical lenses and related components. Its market position is now defunct, with the website serving as a contact point for legacy product sales. The business model is asset liquidation post-closure. The target customers are specialized businesses or individuals interested in optical technology components. There is no evidence of partnerships, subsidiaries, or parent companies. The website lacks modern marketing or analytics tools, indicating low digital maturity. The company maintains direct contact via email and phone but lacks broader digital presence or trust signals.

Security posture

The website exhibits a low security maturity level. There is no indication of HTTPS usage or security headers, no privacy or cookie policies, and no incident response or vulnerability disclosure information. The absence of WHOIS data due to domain naming rules violation further reduces trust. No tracking or analytics scripts are present, minimizing data exposure but also indicating lack of security monitoring. The site is static with no forms or inputs, reducing attack surface but also limiting functionality. Overall, the security posture is weak and non-compliant with modern standards such as GDPR.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure communications.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Improve website accessibility and mobile responsiveness to enhance user experience.
  4. Publish security policies and incident response contacts to build trust and readiness.
  5. Investigate and resolve domain registration issues to ensure WHOIS data availability and legitimacy.

Technical notes

Notes

The website is built using basic HTML and CSS without any detected CMS, frameworks, or modern technologies. There are no scripts or analytics tools present. The site lacks mobile optimization and accessibility features. Performance is likely moderate given the minimal content but could be improved with modern standards. The domain WHOIS lookup failed due to a naming rules violation, indicating possible misconfiguration or invalid domain registration. No hosting provider or infrastructure details are available. The site is static and simple, with no dynamic content or forms.
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.
