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

The website shelfsailor.com operates as an online slot gaming platform branded as IOSBET, targeting the Indonesian market. It offers online slot games with a system designed to increase winning chances daily. The site positions itself as a new entrant in the online gaming sector with a focus on Indonesian users, leveraging affiliate partnerships with established e-commerce platforms like Lazada. The business model revolves around online gaming services with promotional and affiliate marketing components. Technically, the site employs modern JavaScript frameworks including React and uses extensive tracking and analytics tools from Alibaba's ecosystem, indicating a moderate level of digital maturity. However, the site suffers from slow performance due to large page size and numerous resources, and it lacks mobile optimization and accessibility features. Security-wise, the absence of HTTPS and security headers significantly weakens its posture, exposing users to potential risks. No privacy or cookie policies are present, and contact information is missing, which raises compliance and trust concerns. Overall, the site is accessible without WAF or security challenges but requires urgent improvements in security, privacy compliance, and performance to enhance user trust and operational integrity.

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

      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 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';…

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

Shelfsailor.com is positioned as a niche online slot gaming platform with a focus on the Indonesian market, leveraging the popular IOSBET brand. The site integrates with Lazada's ecosystem for affiliate marketing and uses multiple Lazada domains for assets and tracking, indicating a strategic partnership or reliance on Lazada's infrastructure. The business targets online gamblers seeking higher RTP (Return to Player) rates, suggesting a focus on gaming enthusiasts. The lack of detailed business information, such as company registration or contact details, limits transparency. The site’s content and navigation are basic, with a small business size implied by the limited scope and lack of extensive corporate data. The presence of extensive tracking and analytics suggests a data-driven approach to user engagement and marketing. However, the absence of privacy and security policies may hinder long-term growth and regulatory compliance.

Security posture

The security posture of shelfsailor.com is weak due to the absence of a valid SSL/TLS certificate, resulting in no HTTPS support. This exposes users to risks such as data interception and man-in-the-middle attacks. No security headers like HSTS or Content-Security-Policy are implemented, and no vulnerability disclosures or incident response policies are found. The site uses multiple third-party analytics and tracking scripts, which could introduce additional attack surfaces if not properly managed. The lack of privacy and cookie policies further indicates non-compliance with data protection regulations such as GDPR. While no explicit vulnerabilities or malware were detected, the overall security hygiene is poor, necessitating immediate remediation to protect user data and enhance trust.

Recommendations

  1. Implement a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Develop and publish comprehensive privacy and cookie policies with clear consent mechanisms.
  3. Add explicit contact information including security and incident response contacts.
  4. Incorporate security headers such as HSTS, Content-Security-Policy, and X-Frame-Options.
  5. Optimize site performance by reducing resource count and page size, and improve mobile responsiveness.
Technical notes

Notes

The website utilizes modern JavaScript frameworks including React and employs advanced browser APIs like IntersectionObserver and MutationObserver for user interaction tracking. It integrates with Alibaba's Aplus and Goldlog analytics platforms, indicating a sophisticated tracking infrastructure. However, the site suffers from slow load times (over 22 seconds) and a large page size (~3.9 MB), which negatively impacts user experience. The hosting appears to be via Cloudflare, as inferred from DNS records and IP addresses. The site lacks HTTPS, which is a critical technical deficiency. SEO is basic with standard meta tags and Open Graph data present. Accessibility features are minimal, and mobile optimization is only basic. Overall, the technical implementation is moderate but requires significant improvements in security and performance.
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.
