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

HubSpot is a leading enterprise SaaS provider specializing in integrated marketing, sales, customer service, and CRM software designed to help businesses grow. The website reflects a mature digital presence with a professional design, clear branding, and a comprehensive offering targeted at business users seeking scalable software solutions. The technical infrastructure leverages HubSpot's own CMS and marketing platform technologies, ensuring fast performance, mobile optimization, and good accessibility. Security posture is strong with HTTPS enforced and modern web practices, though explicit security headers and public security policies are not evident. The absence of WHOIS data is unusual but likely due to privacy or registry restrictions, not detracting from the site's legitimacy given the brand's prominence. Overall, the site demonstrates high professionalism and trustworthiness, with extensive analytics usage balanced by basic privacy compliance indicators.

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

1 finding rated critical or high. Fix these first.

  1. 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 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

HubSpot operates in the technology sector as an essential enterprise entity providing SaaS solutions for marketing, sales, customer service, and CRM. Its business model focuses on subscription-based software services targeting businesses of various sizes, primarily medium to large enterprises. The company maintains a strong market position with a well-recognized brand and a comprehensive suite of integrated tools. The website's ecosystem includes multiple external domains related to analytics and API services, reflecting a sophisticated digital marketing and operational infrastructure. While direct contact information and detailed corporate data are not visible, the site’s design and content quality indicate a mature and credible business operation with a global reach.

Security posture

The website enforces HTTPS and employs DNS prefetching to enhance security and performance. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected in the provided content, representing an area for improvement. No vulnerabilities or exposed sensitive data were found. The lack of publicly available security policies, incident response contacts, or vulnerability disclosure programs suggests limited transparency in security governance. The extensive use of third-party analytics and tracking services indicates a need for robust privacy and data protection controls. Overall, the security posture is good but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish comprehensive security headers including Content-Security-Policy and X-Frame-Options to mitigate common web attacks.
  2. Provide publicly accessible security and incident response policies to improve transparency and trust.
  3. Establish and disclose a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance privacy compliance by clearly publishing privacy and cookie policies with consent mechanisms aligned with GDPR and other regulations.
  5. Regularly audit third-party analytics and tracking tools to ensure minimal privacy impact and compliance with data protection standards.

Technical notes

Notes

The website is built on HubSpot's proprietary CMS and marketing platform, utilizing modern web standards including HTML5, CSS3, and JavaScript. It employs web fonts for consistent branding and DNS prefetching to optimize resource loading. The site is mobile-optimized with responsive design and accessibility features such as focus-visible outlines and semantic HTML elements. Performance is fast with prioritized image loading and minimal blocking resources. No CMS other than HubSpot CMS was detected. Hosting provider details are not explicit but likely HubSpot's infrastructure. The technical implementation is robust, supporting a high-quality user experience and SEO 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.
