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

Sitelement s.r.o. is a Slovak media agency specializing in online advertising, representing a network of over 130 independent websites with a significant reach in Slovakia. Established in 2008, the company positions itself among the top three internet advertising providers in the Slovak market, offering advanced targeting and innovative advertising formats. The website reflects a professional business presence with detailed service descriptions, client portfolios, and transparent contact information. Technically, the site uses a combination of legacy and modern web technologies, including Bootstrap and Highcharts, but some outdated libraries like jQuery 1.8.2 present potential security concerns. Security posture is moderate, with HTTPS enforced and published anticorruption policies, but lacking modern security headers and formal vulnerability disclosures. Privacy compliance is weak due to the absence of privacy and cookie policies or consent mechanisms. Overall, the site is trustworthy and professionally maintained but would benefit from enhanced security and privacy practices.

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.

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

    • 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

  2. 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"

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 operates in the media sector, focusing on online advertising and media representation. Its business model revolves around aggregating a large network of partner websites to offer advertisers targeted reach and campaign optimization. The presence of numerous client logos and a detailed portfolio indicates a well-established partnership ecosystem. The company targets media agencies and advertisers primarily in Slovakia, leveraging advanced targeting technologies and anti-fraud systems. Growth indicators include continuous development of new advertising formats and technologies. The business maintains transparent contact points with named executives, enhancing credibility. However, the lack of explicit certifications or privacy policies suggests areas for compliance improvement.

Security posture

Sitelement demonstrates a moderate security maturity level. The use of HTTPS and a login form with POST method are positive indicators. The publication of an anticorruption and compliance policy reflects a commitment to ethical standards. However, the website lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which are important for mitigating common web attacks. The use of an outdated jQuery version (1.8.2) exposes the site to known vulnerabilities. No formal vulnerability disclosure or security.txt file is present, limiting transparency in incident response. Privacy compliance is insufficient, with no cookie consent or privacy policy, potentially exposing the company to GDPR risks. Overall, while no critical vulnerabilities are evident, improvements are necessary to elevate security posture and compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance web security.
  4. Develop and publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  5. Conduct regular security audits and penetration testing to identify and remediate potential security weaknesses.

Key observations

  1. Website is a professional media agency site with detailed business info and client portfolio.
  2. No privacy or cookie policy found, indicating compliance gaps.

  6. No WAF or blocking mechanisms detected.
Technical notes

Notes

The website employs a traditional web technology stack with Bootstrap for responsive design, Highcharts for data visualization, and various jQuery plugins for UI enhancements. While the design is professional and navigation is clear, the use of an outdated jQuery version (1.8.2) is a technical debt and security risk. Performance is moderate, with some asynchronous loading of scripts and use of CDN-hosted libraries. Mobile optimization is basic but functional. SEO optimization is minimal, with basic meta tags but no structured data like JSON-LD or Open Graph tags detected. Accessibility features are limited. Hosting details are not explicitly identified, but domain uses Slovakian name servers consistent with the business location. Overall, the technical implementation is solid but would benefit from modernization and enhanced SEO and accessibility practices.
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.
