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

Yelp Inc. operates a leading online platform that connects consumers with local businesses through user-generated reviews, photos, and business information. The support center website provides resources for both consumers and business owners, including FAQs, business page management, advertising, and reservation services. The site targets a broad audience of consumers seeking local business information and business owners managing their Yelp presence. Technically, the site leverages Salesforce Visualforce technology, Amazon AWS hosting, and integrates Google Analytics and Tag Manager for tracking. However, the site suffers from a critical security shortfall due to the absence of a valid SSL certificate and lack of HTTPS support, which significantly impacts its security posture. Privacy policies and terms of service are well documented and linked to official Yelp domains, indicating good compliance practices. Contact information is provided primarily via phone numbers and a search form, but no direct email contacts or incident response channels are visible.

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.

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

Yelp maintains a strong market position as a trusted local business review platform with a large user base and extensive business services. Its business model combines user-generated content with advertising and business tools such as reservations and guest management. The website content and linked domains confirm a consistent and professional brand presence. The use of Salesforce and AWS indicates a mature technical infrastructure. The absence of explicit security policies or vulnerability disclosure mechanisms suggests room for improvement in transparency and security culture. The presence of multiple official Yelp domains as partners reinforces the ecosystem's robustness.

Security posture

The website's security posture is weakened by the lack of a valid SSL certificate and disabled TLS protocols, exposing users to potential risks such as data interception. While security headers like Content-Security-Policy, HSTS, and X-Frame-Options are present, their effectiveness is limited without proper HTTPS. No incident response or vulnerability disclosure information is provided, which could hinder timely handling of security issues. The site does not implement OCSP stapling or session resumption, impacting performance and security. Overall, the site requires urgent remediation of SSL/TLS issues and enhancement of security transparency to meet modern standards.

Recommendations

  1. Immediately obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Enable and configure modern TLS protocols (TLS 1.2 or TLS 1.3) and related security features such as OCSP stapling and session resumption.
  3. Publish a security policy and incident response contact information to improve transparency and trust.
  4. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Regularly audit and update security headers and privacy compliance mechanisms to maintain best practices.
Technical notes

Notes

The website is built using Salesforce Visualforce technology and hosted on Amazon AWS infrastructure, as indicated by IP addresses and resource URLs. It uses legacy jQuery 1.8.3 and integrates Google Analytics and Google Tag Manager for user tracking. The site has a professional design with responsive elements and multilingual support. However, performance metrics are missing or zero, suggesting incomplete performance data or slow loading. Accessibility is basic, and SEO optimization is good with proper meta tags and hreflang links. The lack of valid SSL/TLS is a major technical risk. The site uses multiple external domains for assets and tracking, all consistent with Yelp's ecosystem.
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.
