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.

Business context

Business profile

Bitly operates in the technology sector with a focus on digital marketing tools. Its business model is SaaS-based, targeting enterprises and marketers who require branded link solutions. The company leverages partnerships and integrations to expand its ecosystem. Bitly's competitive advantage lies in its brand recognition, comprehensive analytics, and trusted platform. Revenue streams likely include subscription plans and enterprise contracts. The company demonstrates growth through continuous feature expansion and strong market positioning. The presence of multiple social media channels and a trust center indicates a mature customer engagement strategy.

Security posture

Bitly exhibits a mature security posture with enforced HTTPS, domain registration protections, and consent management via OneTrust. The absence of DNSSEC and security.txt file are minor gaps. No exposed credentials, malware, or phishing indicators were found. The website uses modern analytics and marketing tools responsibly with user consent. Incident response details are not explicitly published, which could impact rapid vulnerability handling. Overall, Bitly maintains strong security practices aligned with industry standards but can improve transparency and DNS security.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and enhance domain security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information on the Trust or Security Center pages.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance user privacy transparency by detailing data retention policies and processing practices.

Technical notes

Notes

The website uses a WordPress CMS with a custom JointsWP theme framework, supported by a modern JavaScript stack including Snowplow Analytics and Google Tag Manager. Hosting is via Amazon AWS CloudFront CDN and Google Cloud DNS, ensuring global content delivery and DNS reliability. Performance is moderate with good mobile responsiveness and accessibility features. The site employs OneTrust for cookie consent, reflecting compliance with privacy regulations. Technical debt appears low, but enabling DNSSEC and publishing security.txt would modernize the security posture further. Overall, the infrastructure supports scalable, secure, and compliant operations.
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.
