LinkStorm is a small technology company founded in 2021, offering an AI-powered SaaS platform focused on optimizing internal linking for SEO professionals, agencies, and publishers. Their product leverages proprietary AI methods to analyze website content and suggest relevant internal links, helping users improve SEO rankings and user engagement. The company positions itself as a niche player with a clear value proposition supported by customer success stories and testimonials. Technically, the website is hosted on DigitalOcean and uses a modern tech stack including JavaScript frameworks, Bootstrap for UI, and integrates multiple marketing and analytics tools such as Google Tag Manager, Hotjar, Microsoft Clarity, Intercom, and Survser. The site is mobile-optimized with good SEO practices and a professional design, though accessibility features are basic. From a security perspective, the site uses HTTPS and has domain transfer protections but lacks DNSSEC and security headers. No explicit security or incident response policies are published, and no cookie consent mechanism is present, indicating room for improvement in privacy compliance. No critical vulnerabilities or suspicious patterns were detected. Overall, LinkStorm presents a credible and professional online presence with a solid business model and technical foundation. Strategic improvements in security policies, privacy compliance, and security headers would enhance trust and compliance posture.

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

7 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 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

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

LinkStorm operates in the competitive SEO technology sector, targeting SEOs, agencies, and publishers with a SaaS subscription model offering tiered pricing plans. Their competitive advantage lies in AI-driven internal linking suggestions and automation features that save time and improve SEO outcomes. The company demonstrates growth potential through documented customer success stories and a clear focus on user experience. Their partnership ecosystem includes social media engagement but no explicit third-party business partners were identified. The business is headquartered in Spain, with domain registration in the US, reflecting a common startup practice. The company maintains a lean operation with a small team and focuses on continuous product development and customer acquisition.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and domain transfer protection. However, the absence of DNSSEC, security headers (such as CSP, HSTS, X-Frame-Options), and lack of published security or incident response policies indicate gaps in security best practices. The site collects user data via forms and uses multiple tracking and analytics tools, but no cookie consent or privacy compliance mechanisms were detected, which may expose the company to GDPR compliance risks. No exposed sensitive data or vulnerable libraries were identified. Incident response readiness and security culture indicators are not publicly visible, suggesting an opportunity to improve transparency and preparedness.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  3. Add a cookie consent banner and detailed cookie policy to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and incident response plan to enhance transparency and trust.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website is built with modern web technologies including JavaScript frameworks and Bootstrap for responsive design. Hosting on DigitalOcean provides reliable infrastructure. Integration with multiple analytics and marketing tools indicates a mature digital marketing approach. Performance is moderate with asynchronous loading of scripts. The site is mobile-optimized and SEO-friendly with proper meta tags and structured data (JSON-LD). However, accessibility features are basic and could be improved. No CMS was detected, suggesting a custom or static site architecture. Technical debt appears low but security enhancements are recommended to reduce risk.
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.
