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

Bluesky is an innovative social media platform focused on building an open foundation for the social internet. Founded in 2022 and based in the US, it offers users a choice in their social experience through an open protocol (AT Protocol), developer APIs, and customizable feeds. The platform targets general internet users seeking alternatives to traditional corporate-controlled social media. Technically, the website employs modern frameworks such as Next.js and React, is hosted on AWS infrastructure, and is optimized for mobile devices with fast performance and good SEO. Security posture is solid with HTTPS and domain protections, but could be enhanced by enabling DNSSEC and implementing security headers. Privacy compliance is currently weak due to the absence of privacy and cookie policies or consent mechanisms. Overall, Bluesky presents a professional, trustworthy, and technically mature web presence with room for improvement in privacy and security transparency.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

Bluesky positions itself as a leader in open social networking, leveraging an open protocol to differentiate from traditional social media giants. Its business model revolves around fostering a developer ecosystem with public APIs and encouraging third-party client development, as evidenced by related domains like Graysky and Deck.blue. The company is a Public Benefit Corporation, enhancing its trustworthiness and social mission appeal. Media coverage from major outlets and endorsements from industry leaders further strengthen its market position. The platform targets a broad audience of social media users and developers, aiming for growth through openness and community engagement.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and domain registration protections in place. However, the lack of DNSSEC and absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represent gaps that could expose users to certain risks. No explicit security policies or incident response contacts are published, which limits transparency and preparedness. The use of Google Tag Manager indicates tracking but lacks accompanying privacy controls or cookie consent banners, which may raise compliance concerns. Overall, the security posture is adequate but would benefit from enhanced technical controls and policy disclosures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to enhance GDPR compliance.
  3. Add security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  4. Publish a security policy and provide clear incident response contact information to improve transparency and readiness.
  5. Review and minimize tracking scripts or provide opt-out options to align with privacy best practices.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on AWS infrastructure with DNS managed by AWS Route 53. The site is well optimized for mobile devices and demonstrates fast loading times and good SEO practices. The use of Google Tag Manager indicates integration of analytics and marketing tools. No CMS beyond domain registration is detected. The technical stack supports scalability and developer engagement, but there is an opportunity to improve security configurations and privacy compliance through additional headers and policies.
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.
