0–100, higher is better. How it is calculated

Bitwarden, Inc. operates a leading open source password management platform trusted by millions globally, serving individuals, families, businesses, and enterprises. Their product suite includes password management, secrets management, passwordless authentication, and developer tools, positioning them strongly in the cybersecurity technology market. The company emphasizes transparency, security, and compliance, supported by certifications such as SOC 2 and ISO 27001. Their business model is primarily SaaS with free and paid tiers, including self-hosting options for enterprises. Technically, Bitwarden employs a modern React-based web platform, leveraging Cloudflare for hosting and CDN services, and integrates analytics tools like Google Tag Manager and Plausible Analytics. The website demonstrates excellent performance, mobile optimization, accessibility, and SEO practices, reflecting a mature digital infrastructure. Security posture is robust, with enforced HTTPS, comprehensive security headers, a bug bounty program, and regular compliance audits. However, DNSSEC is not enabled, and a security.txt file is absent, representing areas for improvement. Privacy compliance is strong, with clear privacy and cookie policies and GDPR adherence. Contact information is available primarily via contact forms, with no explicit phone numbers or emails disclosed. Overall, Bitwarden presents a high-trust, professional, and secure online presence with minimal risk. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, and enhancing incident response transparency to further strengthen their security and compliance posture.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Bitwarden holds a competitive position as a trusted open source password manager with a broad customer base spanning personal users to large enterprises. Their SaaS subscription model, complemented by self-hosting options, caters to diverse market segments. The company benefits from a strong partnership ecosystem and community engagement through forums and open source collaborations. Their revenue streams likely include subscription fees from personal, family, business, and enterprise plans. Growth indicators include continuous product innovation, compliance certifications, and industry recognition. Strategic observations highlight their emphasis on security, transparency, and user trust as key differentiators in a crowded market.

Security posture

Bitwarden exhibits a mature security posture with enforced HTTPS, multiple security headers, and adherence to industry standards such as SOC 2 and ISO 27001. The presence of a bug bounty program and open source codebase enhances vulnerability management and transparency. Compliance with GDPR and other regulations is evident through detailed policies. However, the absence of DNSSEC and a security.txt file indicates room for improvement in DNS security and vulnerability disclosure practices. Incident response contact details are not explicitly provided, which could impact responsiveness in case of security events. Overall, the security culture appears strong, with ongoing audits and community involvement supporting continuous improvement.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information to improve transparency.
  4. Enhance visibility of the Data Protection Officer or privacy contact details.
  5. Continue regular third-party security audits and update compliance documentation.

Technical notes

Notes

The website is built on a modern React framework with a custom CMS likely based on a headless architecture. Hosting and CDN services are provided by Cloudflare, ensuring fast and reliable content delivery. The integration of Google Tag Manager and Plausible Analytics supports comprehensive user behavior tracking and marketing analytics. Performance is optimized with preloading of CSS and JavaScript assets, and mobile responsiveness is excellent. Accessibility features are implemented to a good standard, supporting diverse user needs. Technical risks are minimal, though enabling DNSSEC and improving vulnerability disclosure mechanisms would further reduce potential attack vectors.
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.
