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

Logo.dev is a technology company providing a comprehensive API service that grants developers and businesses access to hundreds of millions of company logos. Their platform is positioned as a leading solution in the logo API market, trusted by tens of thousands of developers. The service offers updated brand assets delivered via a global CDN, supporting various formats such as SVG, PNG, and WebP. The business model is API-as-a-service with tiered pricing plans targeting developers and enterprises needing reliable brand logos for websites and applications. Technically, the website is built on a modern stack including Next.js and React, with authentication handled by Clerk.js. The site is hosted likely on Vercel, ensuring fast performance and excellent mobile optimization. Security is well implemented with HTTPS, multiple security headers, and no exposed sensitive data. Analytics are handled via Fathom Analytics, reflecting a privacy-conscious approach with minimal user tracking. From a security perspective, the site demonstrates strong fundamentals but lacks explicit security policies and incident response contacts. Privacy compliance is good with a comprehensive privacy policy and terms of service, though no cookie consent mechanism was detected. The WHOIS data aligns well with the business identity, supporting legitimacy and trustworthiness. Overall, Logo.dev presents a professional, secure, and well-structured digital presence with minor areas for improvement in privacy and security transparency. The risk profile is low, and the platform is suitable for integration into professional environments requiring reliable logo assets.

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

5 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 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';…

  2. GDPR outside view

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

    • 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

  3. 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

Logo.dev operates in the technology sector, focusing on providing brand asset APIs. Their competitive advantage lies in the breadth of logos available, daily updates, and global CDN delivery. The business targets developers and enterprises, offering solutions for onboarding, job boards, finance, and merchant records. Revenue streams likely include subscription plans for API access. The company maintains a strong partnership ecosystem visible through social media and customer logos. Growth indicators include a large user base and extensive domain coverage. Strategic observations highlight the importance of maintaining data freshness and API reliability to retain market leadership.

Security posture

The security maturity of Logo.dev is solid, with HTTPS enforced and multiple security headers implemented. The use of modern authentication libraries and absence of exposed sensitive data indicate good security hygiene. However, the lack of a public security policy, vulnerability disclosure program, and incident response contacts suggests room for improvement in transparency and readiness. Compliance with GDPR is supported by a comprehensive privacy policy, but cookie consent mechanisms are absent. The security culture appears professional but could benefit from enhanced communication of security practices to users.

Recommendations

  1. Develop and publish a dedicated security policy page outlining security practices and compliance.
  2. Implement a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  3. Add clear incident response contact information, including security and abuse email addresses.
  4. Introduce a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  5. Regularly review and audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website leverages a modern React and Next.js framework, ensuring server-side rendering and fast load times. Authentication is managed via Clerk.js, a reputable identity management solution. Static assets and logos are served through a CDN, enhancing global performance. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed with appropriate meta tags and Open Graph data. Hosting appears to be on Vercel, a platform optimized for Next.js applications. Technical risks are minimal, but continuous monitoring of third-party libraries and scripts is advised to maintain security and performance.
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.
