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

Callan Computers is a well-established ICT solutions and services provider based in Ireland, with a history dating back to 1984. The company offers a broad range of IT products and services including software, hardware, managed connectivity, ERP solutions, and cloud services. They maintain strong partnerships with global technology leaders such as Microsoft, HP, IBM, Cisco, and VMware, positioning themselves as a trusted regional technology partner for businesses across Ireland. The website reflects a professional and consistent brand image with clear navigation and relevant content tailored to their B2B audience. From a technical perspective, the website utilizes modern front-end technologies including Bootstrap and jQuery, and integrates Google Analytics for performance tracking. The site is mobile-optimized and provides a cookie consent mechanism compliant with GDPR requirements, allowing users to manage their privacy preferences. However, there is no evidence of advanced CMS or hosting details, and performance is moderate with room for improvement in accessibility and SEO. Security posture is moderate; while HTTPS usage is assumed but not explicitly confirmed, the site lacks visible security headers and published security policies or incident response contacts. No forms collecting sensitive data were detected, reducing immediate risk exposure. The company holds a Microsoft Accredited Partner certification, enhancing trustworthiness. Overall, the domain registration details align well with the business profile, supporting legitimacy and long-term operation. Strategic recommendations include enhancing security headers, publishing explicit security and incident response policies, improving accessibility and SEO, and maintaining rigorous third-party script audits to mitigate vulnerabilities. These steps will strengthen the company’s security posture and compliance stance, further boosting customer trust and operational resilience.

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

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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

Callan Computers operates as a medium-sized, essential entity in the technology sector, focusing on ICT solutions and services for businesses in Ireland. Their competitive advantage lies in longstanding industry experience since 1984 and strong partnerships with major technology vendors. The business model is B2B, delivering end-to-end IT solutions including software, hardware, managed connectivity, ERP, and cloud services. The company targets business customers seeking reliable technology support and innovation. The partnership ecosystem includes Microsoft, HP, IBM, Cisco, and VMware, which supports their market position as a trusted regional provider. Growth indicators include a stable online presence and continuous service offerings. No parent or subsidiary companies were identified, indicating an independent operation.

Security posture

The current security maturity level is moderate. The website implements a cookie consent mechanism aligned with GDPR, indicating awareness of privacy compliance. However, the absence of explicit security policies, incident response contacts, and security headers suggests gaps in formal security governance. No vulnerabilities or exposed sensitive data were detected in the analyzed content, and no forms collect sensitive personal information on the homepage, reducing attack surface. The use of Google Analytics is transparent and opt-in. To improve, the company should implement security headers (CSP, HSTS), publish incident response and security policies, and ensure SSL/TLS is properly configured and enforced. These improvements will enhance compliance with GDPR and NIS2 directives and strengthen the security culture.

Recommendations

  1. Implement comprehensive security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Publish explicit security policy and incident response procedures on the website with dedicated contact channels.
  3. Conduct regular security audits of third-party scripts and libraries to identify and remediate vulnerabilities.
  4. Enhance accessibility and SEO optimization to improve user experience and search engine visibility.
  5. Maintain and regularly update cookie consent mechanisms to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built using Bootstrap and jQuery, indicating a modern but standard front-end technology stack. Google Analytics is integrated for traffic analysis. The site is mobile responsive and has a clear navigation structure. However, no CMS or hosting provider information is evident. Performance is moderate with no critical errors detected. Accessibility features are basic, and SEO optimization is minimal but present. There is an opportunity to modernize the tech stack by adopting newer frameworks or CMS solutions and improving performance and accessibility standards to reduce technical debt and enhance user engagement.
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.
