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

Mailocator is a SaaS platform operated by Mailnatives, s.r.o., focused on optimizing the customer journey to increase sales through multi-channel marketing campaigns. The platform targets e-commerce shops, companies, and agencies, offering services such as email capture, data enrichment, content personalization, and integration with popular email marketing and e-commerce platforms. The website presents a professional and consistent brand image with clear marketing messaging and customer testimonials, positioning itself as a niche player in the marketing technology space. Technically, the website uses modern web technologies including asynchronous JavaScript loading, Material Icons, and CSS Flexbox Grid for responsive design. Hosting is provided by Active24, a Czech hosting provider, consistent with the company's regional presence. The site is mobile optimized and SEO friendly, though accessibility features are basic. No CMS is detected, indicating a custom-built site. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and does not provide a published security policy or incident response contacts. Privacy compliance is partial, with a privacy policy and terms of service present but no cookie consent mechanism or GDPR compliance indicators. No vulnerability disclosure or security.txt file is found. Overall, the website is trustworthy and professionally maintained with moderate security posture. Strategic improvements in privacy compliance, security headers, and incident response transparency would enhance trust and security maturity.

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

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.

Business context

Business profile

Mailocator operates in the marketing technology sector, focusing on customer journey optimization and email marketing enhancement. Its business model is SaaS-based, targeting small to medium-sized e-commerce businesses and marketing agencies. The platform's competitive advantage lies in its multi-channel campaign capabilities, extensive integration options, and user-friendly interface. Revenue streams likely include subscription fees for platform access and premium features. The company maintains partnerships with various email marketing and e-commerce platforms, enhancing its ecosystem. Growth indicators include active customer testimonials and a 14-day trial offer to attract new users. The company is based in the Czech Republic, with a clear regional focus but international reach via web presence and social media.

Security posture

The security maturity level of Mailocator's website is moderate. HTTPS is enforced, ensuring encrypted communication. However, the absence of key security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces protection against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy and incident response contacts limits transparency and preparedness for security incidents. Privacy compliance is partial, with no cookie consent mechanism or GDPR explicit indicators. The platform would benefit from implementing security best practices including security headers, vulnerability disclosure policies, and enhanced privacy controls to improve its security posture and compliance.

Recommendations

  1. Implement and enforce security headers such as CSP, HSTS, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and enhance user privacy transparency.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built with a custom front-end using modern CSS and JavaScript techniques, including asynchronous script loading and responsive design via Flexbox Grid. It uses Material Icons hosted on Google Fonts and loads proprietary scripts from app.mailocator.com. The hosting provider is Active24, a Czech-based service, consistent with the company's regional presence. Performance is moderate with no obvious blocking scripts or heavy resources. SEO is well addressed with proper meta tags, Open Graph, and Twitter card metadata. No CMS or major frameworks like React or Angular are detected, indicating a lightweight custom solution. Technical risks include lack of security headers and incomplete privacy compliance which could impact user trust and regulatory adherence.
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.
