Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 as a SaaS provider in the technology sector, focusing on link management solutions that enable businesses to create, customize, and track branded links. Its competitive advantage lies in its long-standing market presence, trusted brand reputation, and comprehensive service offerings that integrate URL shortening, QR code generation, and analytics. Revenue streams likely include subscription plans and enterprise services. The target customer segments are marketers, enterprises, and digital agencies seeking enhanced link branding and tracking capabilities. Bitly's partnership ecosystem includes integrations with various marketing and analytics platforms, enhancing its value proposition. The company demonstrates growth through continuous feature expansion and compliance with evolving privacy regulations.

Security posture

Bitly exhibits a mature security posture with enforced HTTPS, domain registration safeguards, and compliance with recognized standards such as SOC 2 Type 2, GDPR, and CCPA. The presence of cookie consent mechanisms and privacy policies indicates strong data protection practices. However, the absence of DNSSEC and some security headers suggests room for enhancement. No vulnerabilities or exposed sensitive information were detected. Incident response contact details and vulnerability disclosure mechanisms are not explicitly provided, which could be improved to enhance security readiness and transparency. Overall, Bitly maintains a secure environment appropriate for its enterprise clientele.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide explicit incident response contact information (e.g., security@bitly.com) on the website or trust center.
  5. Continue to enhance privacy and accessibility features to maintain compliance and user trust.

Technical notes

Notes

The website is built on WordPress CMS, hosted on Amazon AWS infrastructure with Cloudfront CDN for content delivery, ensuring fast performance and scalability. It uses modern JavaScript libraries and frameworks including Google Tag Manager for analytics, Optimizely for experimentation, and UserWay for accessibility compliance. The site is mobile-optimized and SEO-friendly with proper meta tags and structured data (JSON-LD). Technical debt appears minimal with well-maintained assets and caching strategies. Opportunities exist to improve DNS security and HTTP security headers to reduce risk exposure.
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.
