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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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

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 · found on this site
  • 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

Business profile

OmniSys operates in the technology sector focusing on B2B IT services in Ireland. Their business model centers on delivering cost-efficient, tax-efficient, and tailored IT infrastructure solutions that improve cash flow and reduce costs for clients. The company leverages partnerships with web design and development firms to enhance their digital presence and client offerings. Their market position is strong as a reputable IT service provider with a history of steady growth since 2001. The presence of case studies and a clear service portfolio indicates a mature business with a focus on customer success and long-term relationships. The company targets Irish businesses seeking reliable IT consultancy and support, with a focus on security and cloud services as key growth areas.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no visible exposure of sensitive data. Cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of explicit security policies, incident response information, and vulnerability disclosure mechanisms indicates areas for enhancement. Security headers are not detected in the HTML content, suggesting potential improvements in HTTP response configurations. The use of well-known WordPress plugins and themes implies regular updates are necessary to mitigate vulnerabilities. Overall, the security maturity is moderate to good, with recommendations to formalize security policies and implement additional HTTP security headers to strengthen defenses.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Ensure all WordPress plugins and themes are regularly updated to mitigate known vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Notes

The website is built on WordPress CMS with a modern tech stack including PHP, JavaScript, jQuery, LayerSlider, WooCommerce, WPBakery Page Builder, and Mailchimp integration. The site uses responsive design techniques and is optimized for mobile devices. Performance is moderate with potential for improvement through optimization of scripts and assets.

Overall, the technical infrastructure supports a professional and functional online presence with room for modernization and performance tuning.
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.
