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. 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

BigHub operates in a competitive AI consultancy market, targeting medium to large enterprises seeking to implement AI-driven business transformations. Their competitive advantage lies in deep industry expertise, long-term partnerships, and a comprehensive service offering from strategy to implementation. Revenue streams likely include consulting fees, custom AI development, and ongoing support contracts. The company demonstrates strong growth indicators through client testimonials and media recognition. Their partnership ecosystem includes leading cloud and AI technology providers, enhancing their solution capabilities. Strategic observations include the need to improve transparency in privacy and security policies to align with evolving regulatory requirements and to enhance trust with prospective clients.

Security posture

BigHub exhibits a mature security posture with HTTPS enforced and use of Cloudflare Turnstile captcha to protect forms from abuse. The presence of ISO certifications (27001, 20000-1, 9001) indicates adherence to recognized security and quality management standards. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No public incident response or vulnerability disclosure policies were found, which could impact readiness and transparency. Privacy compliance is basic, lacking visible cookie consent banners or detailed privacy policies. Overall, the security maturity is good but could be enhanced by publishing comprehensive security and privacy documentation and implementing additional HTTP security headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance and user trust.
  2. Implement and configure HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Provide a public security policy and incident response contact information to enhance transparency and preparedness.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Improve WHOIS data transparency by ensuring domain registration details are complete and publicly accessible.

Technical notes

Notes

The website leverages a modern tech stack including Webflow CMS, GSAP animations, Flickity carousels, and integrates multiple analytics and marketing tools such as Microsoft Clarity, Google Tag Manager, Bing Ads, and LinkedIn Insight Tag. Hosting is via Webflow's CDN, ensuring fast content delivery and good performance. The site is mobile-optimized with responsive design and accessibility features such as focus outlines and semantic HTML. Technical debt appears low with no broken elements or errors detected. Opportunities for modernization include enhancing security headers and formalizing privacy and security documentation to meet best practices and regulatory expectations. Technical risks are minimal but include potential privacy compliance gaps and incomplete domain registration transparency.
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.
