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

Bloglovin’ is a media and technology platform focused on enabling users to follow and discover blogs easily. It offers a web platform and mobile applications for iOS and Android, positioning itself as a popular blog aggregation service. The website provides key services such as blog following, content curation, and blog addition, targeting blog readers and bloggers globally. The presence of social media channels and app store links supports its active market presence. Technically, the site uses modern JavaScript frameworks including React, integrates with Google Analytics, Quantcast, and Facebook SDK for analytics and marketing, and employs HTTPS for secure communication. The site is moderately optimized for performance and mobile devices, with good SEO and basic accessibility features. However, some security best practices such as security headers and explicit cookie consent mechanisms are missing. From a security perspective, the site enforces HTTPS and uses secure form inputs, but lacks visible security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS data reduces domain registration trustworthiness, but the website content and ecosystem indicate legitimate operation. Overall, Bloglovin’ presents a professional and trustworthy platform with good content quality and technical implementation. Improvements in privacy compliance and security posture, especially around cookie consent and security headers, would enhance its risk profile and user trust.

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

8 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 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 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. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Bloglovin’ operates in the media and technology sectors as a blog discovery and aggregation platform. Its business model revolves around content curation, user engagement through following blogs, and monetization via affiliate marketing and advertising networks such as Avantlink, Admitad, and Commission Factory. The platform targets blog readers and bloggers, offering mobile apps to expand reach. The company maintains a strong social media presence across Facebook, Twitter, Instagram, Pinterest, and TikTok, supporting brand visibility and user engagement. The lack of direct contact emails or phone numbers suggests a primarily digital-first customer support approach via help sites and contact forms. The absence of WHOIS data is a notable anomaly but does not appear to impact operational legitimacy. Strategic partnerships with affiliate networks and advertising platforms indicate a mature marketing ecosystem.

Security posture

Bloglovin’ demonstrates a moderate to good security posture with mandatory HTTPS usage and secure form handling. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces protection against common web attacks. No explicit security policies or incident response contacts are published, which could hinder vulnerability reporting and incident management. The site collects user data via forms but lacks visible cookie consent banners, potentially impacting GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the analysis. The missing WHOIS data raises concerns about domain registration transparency but does not directly affect site security. Overall, the platform would benefit from enhanced security headers, published security policies, and improved privacy compliance mechanisms.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Add a clear and accessible cookie consent banner to comply with GDPR and enhance user privacy transparency.
  3. Publish a dedicated security policy page including incident response contacts and vulnerability disclosure procedures.
  4. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.
  5. Enhance accessibility features to improve usability for all users and meet modern web standards.

Technical notes

Notes

The website is built using modern web technologies including React and integrates multiple third-party analytics and marketing tools such as Google Analytics, Quantcast, and Facebook SDK. It uses HTTPS with a presumably strong SSL configuration. The site loads multiple external scripts and styles from a dedicated CDN (static.blovcdn.com), indicating a content delivery optimization strategy. Performance is moderate with good mobile optimization. The site lacks explicit CMS identification and hosting provider details. There is room for improvement in accessibility and security header implementation. The technical infrastructure supports a scalable and interactive user experience but could benefit from modernization in privacy and security controls.
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.
