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

2 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 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

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

Bitly operates a SaaS business model targeting marketers and enterprises seeking branded link solutions. Its revenue streams likely include subscription plans and enterprise services. The company maintains a strong brand presence with partnerships and integrations, supported by a comprehensive resource library and developer ecosystem. Bitly's competitive advantage lies in its trusted brand, extensive analytics, and marketing tools. The website content and structure indicate a focus on enterprise clients and marketing professionals, with clear calls to action for sign-up and quotes. The presence of a Trust Center and Security Center highlights a commitment to transparency and customer trust.

Security posture

Bitly demonstrates a mature security posture with HTTPS enforcement, multiple security headers, and domain status protections that prevent unauthorized domain transfers or deletions. The website includes cookie consent mechanisms compliant with GDPR. However, the absence of DNSSEC and a publicly available security.txt file are minor gaps. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information is not explicitly provided, which could be improved. Overall, Bitly's security practices align well with industry standards for SaaS providers.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file at the root domain to facilitate vulnerability disclosures.
  3. Add explicit incident response contact information (e.g., security@bitly.com) on the Trust or Security Center pages.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Consider obtaining and displaying recognized security certifications (e.g., ISO 27001) to strengthen trust.

Technical notes

Notes

The website is powered by WordPress CMS hosted on Amazon AWS infrastructure, utilizing modern JavaScript libraries and tracking tools such as Snowplow and Google Tag Manager. Performance is optimized with deferred and async script loading, and mobile responsiveness is excellent. Accessibility features are well implemented, including skip navigation links and ARIA roles. SEO is supported by comprehensive meta tags, Open Graph data, and JSON-LD structured data. The technical stack is modern and well maintained, with opportunities to further improve DNS security and incident response readiness.
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.
