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 a SaaS provider, focusing on customer relationship management and business growth tools. Its competitive advantage lies in its integrated AI-powered platform that combines multiple business functions into a single ecosystem. Revenue streams include subscription-based software plans, premium services, and partner ecosystem offerings. The company targets diverse customer segments including startups, small businesses, and enterprises, with tailored solutions for each. Strategic partnerships and a robust marketplace enhance its ecosystem. HubSpot's global reach and multi-language support facilitate international market penetration. The company emphasizes innovation through AI integration, positioning itself as a market leader in customer platform technology.

Security posture

HubSpot demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and adherence to recognized frameworks such as ISO 27001 and SOC 2. The website shows no signs of exposed sensitive data or vulnerable libraries. Secure forms and input handling are evident. However, there is no explicit public vulnerability disclosure policy or security.txt file detected, which could enhance transparency and incident response readiness. Incident response contact channels are not prominently displayed. Overall, the security culture appears strong, supported by certifications and best practices, but could benefit from improved public communication on vulnerability management.

Recommendations

  1. Publish a public vulnerability disclosure policy and security.txt file to enhance transparency and facilitate responsible reporting.
  2. Prominently display incident response contact information to improve security communication and readiness.
  3. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.
  5. Continue investing in accessibility and mobile optimization to ensure inclusive user experiences.

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.
