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

10 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

SMLoG operates a B2B SaaS model focused on digital marketing efficiency and fraud prevention. Its competitive advantage lies in its proprietary tracking technology capable of persistent user identification despite IP or cookie changes, and a comprehensive suite of tools including real-time alerts, chat support, and automated bidding. The company maintains a strong partnership with Megazone for hosting and leverages Google Play for mobile app distribution. Revenue streams likely include subscription fees for software services and premium features. The presence of a 14-day free trial indicates a customer acquisition strategy aimed at lowering entry barriers. The company’s transparent business registration and contact information enhance credibility. Growth indicators include new product launches such as the automated bidding solution and integrated ad management platform. The ecosystem includes partnerships with hosting providers and advertising platforms.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and domain registration locked via clientTransferProhibited status. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks published security or incident response policies, which could be a compliance gap especially under GDPR or similar regulations. The use of multiple tracking and analytics tools indicates extensive user data collection, but no explicit cookie consent mechanism was found, potentially impacting privacy compliance. Overall, the security maturity is good but could be improved by adopting best practices in headers and privacy transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Introduce a clear cookie consent banner and privacy notice to improve GDPR and global privacy compliance.
  3. Publish detailed security and incident response policies accessible from the website to build trust and demonstrate compliance.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure secure integrations.
  5. Enhance accessibility features and conduct periodic performance optimizations to improve user experience across all devices.

Technical notes

Notes

The website is built on a solid technical foundation using Bootstrap 4.5.2 and jQuery 1.11.3, which are somewhat dated but still widely supported. It integrates multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, Facebook Pixel, and Mixpanel, indicating a data-driven approach to user engagement and marketing optimization. Hosting is provided by Megazone, a reputable Korean hosting provider. The site is mobile-optimized with responsive design and includes an Android app available via Google Play. Performance is moderate with no major issues detected, though some CSS and JavaScript could be modernized. The absence of a CMS suggests custom or static site architecture, which can reduce attack surface but may increase maintenance overhead. Overall, the technical implementation supports the business goals effectively 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.
