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 on a SaaS subscription model, offering integrated marketing, sales, and service software. Its competitive advantage lies in its all-in-one platform approach and strong brand recognition. Revenue streams include software subscriptions and professional services. The target customer segments range from small businesses to large enterprises. HubSpot maintains a strong partnership ecosystem and invests in security and compliance certifications to support its global customer base. The company is headquartered in the United States and has a large enterprise size. The website content and structure support its business model effectively.

Security posture

The security maturity level of HubSpot's website is high, with no evident vulnerabilities or exposed sensitive data. The presence of multiple security headers, HTTPS enforcement, and published incident response contacts indicate a proactive security culture. Compliance with GDPR and other privacy regulations is evident. However, the absence of a security.txt file is noted as an area for improvement. The company demonstrates readiness for incident response and maintains certifications that reinforce its security posture. Overall, the risk level is low, with recommendations focusing on continuous improvement and transparency.

Recommendations

Notes

HubSpot's technical infrastructure is modern and robust, leveraging React and Node.js frameworks and integrating Google Analytics and Tag Manager for analytics. The website is hosted on reliable infrastructure, likely AWS or proprietary HubSpot servers, ensuring fast performance and scalability. The CMS is HubSpot's own platform, optimized for marketing and sales use cases. Accessibility and SEO optimizations are well implemented, contributing to excellent user experience and discoverability. Technical risks are minimal, with opportunities for modernization focused on enhanced security transparency and continuous performance tuning.
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.
