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

Rankai is a newly founded AI-powered SEO agency focused on delivering high-quality SEO services to startups and SMBs at a competitive price point. The company leverages a hybrid approach combining human SEO expertise with AI-driven content creation and optimization to generate significant organic traffic growth for clients. Backed by reputable investors such as OpenAI, Andreessen Horowitz, Y Combinator, and Microsoft, Rankai positions itself as an innovative player in the SEO technology space. Technically, the website is built on modern frameworks including Next.js and React, with integrations for analytics (Google Analytics, Plausible, PostHog) and customer engagement (Intercom). The site is well-optimized for performance, mobile responsiveness, and SEO best practices, reflecting a mature digital infrastructure for a startup. Hosting is via GoDaddy, with domain privacy protection enabled. From a security perspective, the site uses HTTPS and follows basic security best practices but lacks advanced security headers and published security policies. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is partial, with a clear privacy policy and terms of service but no cookie consent mechanism. WHOIS data indicates a legitimate startup with privacy protection justified by business type. Overall, Rankai presents a professional, trustworthy, and technically sound online presence with room for improvement in privacy compliance and security transparency. Strategic enhancements in these areas will strengthen trust and regulatory adherence.

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

Rankai operates in the competitive SEO services market, targeting startups and SMBs seeking affordable yet effective organic search growth. Its unique selling proposition is the integration of AI with human SEO expertise to deliver 3x more content and faster results than traditional agencies. The flat monthly pricing model simplifies customer acquisition and retention. The company benefits from strong venture backing, enhancing credibility and potential for growth. Its marketing ecosystem includes partnerships with major technology and investment firms, and it leverages modern digital marketing tools for customer engagement and analytics. The business model emphasizes scalability through automation while maintaining quality via expert oversight.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. However, it lacks advanced security headers such as Content-Security-Policy and Strict-Transport-Security, which could mitigate certain attack vectors. There is no publicly available security policy or incident response plan, which limits transparency and preparedness perception. Privacy compliance is partial; while a privacy policy and terms of service exist, the absence of a cookie consent mechanism may pose regulatory risks under GDPR and similar laws. No known vulnerabilities or malicious indicators were found in the site content or scripts. Overall, the security posture is adequate for a startup but should be enhanced to meet enterprise standards.

Recommendations

  1. Implement a cookie consent banner to ensure GDPR and privacy regulation compliance.
  2. Publish a comprehensive security policy and incident response plan accessible on the website.
  3. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly audit third-party scripts and dependencies to detect and mitigate vulnerabilities.

Notes

The website is built using Next.js and React, indicating a modern, server-side rendered React framework optimized for SEO and performance. It integrates Google Tag Manager for analytics and marketing, Plausible for privacy-focused analytics, and PostHog for user behavior tracking. Intercom is used for customer support and engagement. The site is hosted on infrastructure associated with GoDaddy, as indicated by WHOIS and nameservers. Performance is fast with good mobile optimization and accessibility features.

The technical stack supports scalability and rapid content delivery, aligning with the business model of high-volume content creation and continuous optimization.
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.
