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

The website alu.hr represents the Akademija likovnih umjetnosti, an established fine arts academy affiliated with the University of Zagreb in Croatia. It serves students, faculty, and visitors by providing academic information, event announcements, and cultural project details. The institution is mature with a domain age of 22 years and a consistent registration profile. Technically, the site runs on Apache with Ubuntu, uses CMS Contenido 4.8, and includes older JavaScript libraries such as jQuery 1.9.0. However, the website suffers from outdated technology and lacks modern performance and accessibility optimizations. Security posture is weak due to the absence of a valid SSL certificate and proper HTTPS configuration, exposing users to risks. Privacy compliance is minimal, with no visible privacy or cookie policies, and no contact information is explicitly provided on the homepage. Overall, the site is functional but requires significant improvements in security, privacy, and technical modernization to meet current standards.

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. 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

The Akademija likovnih umjetnosti operates as a medium-sized educational institution within the Croatian higher education sector, focusing on fine arts. Its business model centers on academic education, cultural exhibitions, and international cooperation. The website targets students, academic staff, and art enthusiasts. The institution benefits from its affiliation with the University of Zagreb, enhancing its credibility and market position. The lack of modern digital marketing or analytics tools suggests a traditional approach to outreach. The site links to partner domains within the academic ecosystem, such as srce.hr and obnova.alu.hr, indicating collaboration within the university network. Growth opportunities lie in digital transformation and enhanced online engagement.

Security posture

Security maturity is low due to the absence of a valid SSL certificate and lack of HTTPS enforcement, which is a critical vulnerability. Although some security headers like Strict-Transport-Security are present, they are not effectively enabled. The site does not implement modern TLS protocols or session resumption, and CAA DNS records are malformed. No incident response or security policies are published, and no contact channels for security issues are provided. The use of outdated JavaScript libraries may expose the site to known vulnerabilities. Overall, the security posture poses risks to user data confidentiality and site integrity.

Recommendations

  1. Obtain and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Update the technology stack, including JavaScript libraries and CMS, to supported and secure versions.
  3. Publish clear privacy and cookie policies to comply with GDPR and enhance user trust.
  4. Add explicit contact information including emails and phone numbers for general and security-related inquiries.
  5. Implement additional security headers and review cookie security settings to harden the site against common web attacks.
Technical notes

Notes

The website is hosted on an Apache server running on Ubuntu, using CMS Contenido 4.8 and older JavaScript libraries such as jQuery 1.9.0, Fancybox, and EasySlider. The site lacks modern performance optimizations and mobile responsiveness is basic. SEO and accessibility features are minimal. The SSL/TLS configuration is incomplete, with no valid certificate and no TLS protocols enabled, resulting in HTTP-only access. DNS records are mostly well configured except for malformed CAA records. The site does not use analytics or tracking tools, indicating minimal data collection. Overall, the technical infrastructure is functional but outdated and requires modernization to improve security, performance, and 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.
