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

6 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

      SSL Certificate Expires Soon

      SSL certificate expires in 25 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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 technology and media sectors, targeting podcast creators and enterprises seeking hosting and monetization solutions. Its business model is subscription-based with additional revenue from advertising services. The company leverages partnerships with advertising networks and integrates tracking and marketing tools to optimize user engagement and monetization. The domain's long history and consistent branding reinforce its credibility. The absence of privacy protection in WHOIS data aligns with its transparent business approach. The company maintains a strong online presence with active social media channels and customer engagement via Trustpilot. Growth potential lies in expanding enterprise podcasting services and enhancing security and compliance frameworks.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and domain transfer protections in place. However, DNSSEC is not enabled, which is a notable gap in DNS security. The absence of explicit security headers like Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No public security policy or incident response contacts were found, which could hinder transparency and trust in security matters. The cookie consent mechanism and privacy policy indicate compliance with GDPR and related regulations. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security maturity is adequate but could be improved by implementing additional headers, DNSSEC, and publishing security policies.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and publish a formal security policy and incident response contact information.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain and regularly update privacy and cookie policies to ensure ongoing compliance with evolving regulations.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor and Yoast SEO plugins, providing a robust and flexible platform for content management and SEO optimization. The use of Google Tag Manager, Hotjar, and Trustpilot widgets indicates a mature approach to analytics, user feedback, and marketing. The site loads a variety of JavaScript libraries and CSS frameworks to enhance user experience and interactivity. Performance is moderate with good mobile optimization and accessibility features. The domain is registered with Tucows Domains Inc., a reputable registrar, and has been active since 2004, indicating stable infrastructure. Technical risks include the lack of DNSSEC and incomplete security header implementation, which should be addressed to reduce attack surface.
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.
