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

HubSpot is a leading enterprise SaaS company providing a comprehensive customer platform that integrates marketing, sales, customer service, and CRM software to help businesses grow. The website reflects a mature digital presence with excellent design, clear branding, and a focus on business users seeking integrated software solutions. Technically, the site leverages HubSpot's own CMS platform, integrates Google Analytics and Tag Manager for tracking, and employs modern web fonts and responsive design to ensure a fast and accessible user experience. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though explicit security headers and incident response information are not present in the analyzed content. Privacy compliance indicators such as privacy and cookie policies are not detected in the provided HTML snippet, which is a gap for full compliance. Overall, the website is professional and trustworthy, though the absence of WHOIS data limits domain registration verification. Strategic recommendations include enhancing transparency around privacy and security policies and publishing vulnerability disclosure and incident response details.

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 SaaS provider with a strong market position in CRM and business software. Its business model focuses on subscription-based software services targeting businesses of various sizes seeking integrated marketing, sales, and customer service tools. The company maintains a consistent brand presence and leverages a broad ecosystem of subdomains and integrations. While no explicit business registration or VAT information is found, the brand's global recognition and extensive platform usage indicate a mature and stable operation. The website's content and structure support a professional image aimed at business customers, with extensive use of analytics and marketing tools to optimize engagement and conversion.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no visible security vulnerabilities or exposed sensitive data. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security hardening. No security policy, incident response contacts, or vulnerability disclosure mechanisms are found, which are important for transparency and compliance. The absence of these elements suggests room for improvement in security communication and incident readiness. No malware or phishing indicators are detected. Overall, the security maturity is moderate to good but could be enhanced by publishing formal security and privacy documentation and implementing additional HTTP security headers.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently on the website to improve privacy compliance.
  2. Implement and disclose a formal security policy and incident response plan including contact channels for security issues.
  3. Add HTTP security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance security posture.
  4. Provide a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance transparency by including contact information for data protection officers or privacy contacts.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing modern web fonts and optimized for mobile devices with responsive design. It integrates Google Tag Manager and Google Analytics for tracking and performance monitoring. DNS prefetching is used to improve load times for external resources. The site shows good SEO practices with meta tags and Open Graph data for social sharing. Accessibility features such as focus-visible outlines and semantic HTML are present, contributing to a good user experience. Performance is fast with prioritized image loading. However, no explicit hosting provider information is found. The technical implementation is modern and well-executed, supporting a professional and scalable web presence.
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.
