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

HTA Software is a Dutch software development company specializing in creating software solutions for local governments, healthcare, public sector, real estate, and transport industries. Established in 1994, the company offers both standard and custom software products, including appointment scheduling, digital reception, customer guidance systems, contract management, and logistics platforms. Their market position is that of a niche provider serving multiple sectors with tailored software solutions. Technically, the website is built on WordPress using the Avada theme and Yoast SEO plugin, with integrations such as Google Analytics and Cookiebot for privacy compliance. The site demonstrates good SEO, accessibility, and mobile optimization. Security-wise, the site uses HTTPS and DNSSEC, with a cookie consent mechanism in place, but lacks explicit security policy and incident response information. Overall, the website is professional and trustworthy, though it would benefit from publishing explicit privacy and terms of service pages and providing direct contact information.

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. 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. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

HTA Software targets a specialized market segment including local governments, healthcare providers, and public sector organizations, offering software solutions that streamline operational processes. Their business model focuses on both standard and custom software development, indicating a service-oriented revenue stream. The company maintains a digital presence with social media on Instagram and LinkedIn, enhancing brand visibility. The website content and structured data reflect a consistent brand identity and clear sector focus. Growth indicators include new product launches such as reservation software. The partnership with Cookiebot for cookie consent shows attention to privacy compliance. However, the absence of direct contact details and formal policy documents suggests room for improvement in customer engagement and compliance transparency.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and DNSSEC active, reducing risks of DNS spoofing and ensuring encrypted communications. The use of Cookiebot indicates compliance with cookie consent regulations. However, the lack of visible security headers and absence of a published security policy or incident response contact reduces transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses common third-party scripts like Google Analytics and jQuery, which should be regularly audited for vulnerabilities. Overall, the security maturity is moderate to good but could be enhanced by publishing security policies, adding security headers, and providing incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website.
  2. Add a terms of service page to clarify user agreements and legal disclaimers.
  3. Include direct contact information such as company email and phone numbers for support and inquiries.
  4. Implement and publish a security policy and incident response procedures to improve trust and compliance.
  5. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Avada theme and Yoast SEO plugin, indicating a mature and widely supported technical stack. It uses jQuery and Google Analytics for interactivity and analytics, respectively. Cookiebot is integrated for cookie consent management, reflecting GDPR compliance efforts. The site shows good mobile responsiveness and accessibility features. Performance is moderate, with some optimization possible. Hosting details are limited but the domain registrar is Realtime Register with DNSSEC enabled, enhancing DNS security. The site could benefit from additional security headers and performance optimizations to reduce technical debt and improve user experience.
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.
