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

MAILservis is a Czech-based email marketing service operated by NETservis s.r.o, providing automated email campaign tools and analytics primarily targeting businesses seeking to enhance their online marketing. The website demonstrates a mature digital presence with integrations to major platforms like Google Analytics and Seznam.cz, and offers a comprehensive cookie consent mechanism ensuring GDPR compliance. The technical infrastructure includes own email servers and modern marketing technologies, though some legacy components like an outdated jQuery version are present. Security posture is generally strong with HTTPS and email authentication standards implemented, but lacks some HTTP security headers and explicit security policies. WHOIS data is unavailable, which slightly reduces domain trustworthiness, but the detailed contact information and business references support legitimacy. Overall, the site is professional, user-friendly, and well-optimized for mobile users.

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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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 company positions itself as a reliable and experienced provider in the Czech email marketing sector with over 10 years of operation and a large volume of monthly emails sent. Its business model is SaaS-based, offering tailored solutions and integrations with e-commerce and CRM systems. The presence of notable clients such as Makro and Národní Muzeum indicates strong market penetration and trust. The company maintains partnerships with related service providers and offers comprehensive customer support. Revenue streams likely include subscription fees based on recipient volume and frequency. The website content and client testimonials reinforce a strong brand reputation and customer satisfaction focus.

Security posture

MAILservis exhibits a solid security foundation with enforced HTTPS, use of DKIM, SPF, and DMARC for email authenticity, and a transparent cookie consent mechanism. However, the absence of key HTTP security headers (e.g., Content Security Policy, HSTS) and the use of an outdated JavaScript library (jQuery 1.7.1) present potential vulnerabilities. No explicit security or incident response policies are published, and no security.txt or vulnerability disclosure information is available, which could hinder coordinated vulnerability management. The site does not expose sensitive data and uses secure forms with proper input validation. Overall, the security posture is good but could be improved by addressing these gaps.

Recommendations

  1. Implement standard HTTP security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Upgrade jQuery and other JavaScript libraries to current versions to mitigate known vulnerabilities.
  3. Publish explicit security and privacy policies, including incident response and data protection officer contact details.
  4. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance accessibility compliance to improve user experience for all visitors.

Technical notes

Notes

The website uses a combination of legacy and modern technologies including jQuery 1.7.1, Google Analytics, Google Tag Manager, and FontAwesome Pro icons. It loads fonts from Google Fonts and uses a custom cookie consent tool (KookieCheck). The site is mobile responsive with good design quality and clear navigation. Performance is moderate, with some potential improvements in script optimization and updating outdated libraries. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. SEO is basic but present with proper meta tags and viewport settings. Overall, the technical implementation supports the business goals but could benefit from modernization and enhanced security 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.
