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

5 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. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Libsyn operates in the media and technology sectors, focusing on podcast hosting, distribution, and monetization. Their business model is subscription-based with additional revenue from advertising partnerships. The company targets podcasters ranging from hobbyists to enterprises and educational institutions, offering tailored solutions including enterprise podcasting and podcast advertising. The presence of a subsidiary, LibsynEDU, indicates diversification into educational podcasting. The company maintains strong brand consistency and trust signals such as social media presence and third-party reviews. Their partnership ecosystem includes advertising platforms integrated within their services. Growth indicators include continuous website updates, SEO optimization, and integration of advanced analytics and consent management tools.

Security posture

Libsyn.com demonstrates a moderate to good security maturity level. The use of HTTPS and domain status flags clientTransferProhibited and clientUpdateProhibited provide foundational security. The website employs OneTrust for cookie consent, indicating attention to privacy regulations such as GDPR. However, the absence of DNSSEC and limited visible security headers suggest areas for improvement. No explicit vulnerabilities or exposed sensitive data were detected in the website content. The lack of a published security policy or incident response contact reduces transparency in security governance. Overall, the security posture is adequate for the business type but could be enhanced by adopting additional best practices and publishing security-related policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and trust.
  4. Regularly update all JavaScript libraries, especially jQuery, to the latest secure versions to avoid known vulnerabilities.
  5. Continue to maintain and enhance privacy compliance mechanisms, including clear data retention policies and user rights information.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and Yoast SEO for search engine optimization. It integrates multiple third-party analytics and marketing tools including Google Analytics, Google Tag Manager, Hotjar, and Trustpilot widgets. The site is mobile optimized and accessible with good SEO practices evident from meta tags and structured data in JSON-LD format. Performance is moderate, likely influenced by multiple external scripts and plugins. The domain is registered with Tucows Domains Inc. since 2004, indicating a mature and stable infrastructure. Technical risks include the lack of DNSSEC and incomplete security header implementation, which could be addressed to reduce attack surface and improve overall security posture.
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.
