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

HackerOne is a leading global platform specializing in offensive security, combining AI capabilities with a vast community of security researchers to identify and remediate vulnerabilities across the software development lifecycle. The company offers a comprehensive suite of services including AI Red Teaming, Bug Bounty programs, Pentest as a Service, and Vulnerability Disclosure Programs, positioning itself as a trusted partner for enterprises seeking continuous security coverage. The website demonstrates a mature digital presence with professional design, responsive layout, and extensive content tailored to security professionals and enterprise clients. Technically, the site leverages Drupal CMS, integrates modern analytics and marketing tools, and employs HTTPS with good security practices, although some security headers could be improved. The security posture is strong with dedicated incident response contact points and privacy compliance mechanisms in place. However, the absence of WHOIS data for the domain is unusual and warrants further investigation to confirm domain registration legitimacy. Overall, HackerOne presents a credible, professional, and secure online presence aligned with its market leadership in cybersecurity services.

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.

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

Business profile

HackerOne operates in the technology sector, focusing on cybersecurity and AI security solutions. Its business model revolves around providing a platform that enables enterprises to leverage crowdsourced security testing and AI-powered vulnerability detection. The company targets large enterprises and security teams, emphasizing continuous security testing and risk reduction. The presence of high-profile customers such as Salesforce, IBM, and Adobe underscores its strong market position. HackerOne's partnership ecosystem includes major cloud providers like AWS and community platforms, enhancing its service offerings and reach. The website content and structure reflect a well-established enterprise with a focus on trust, innovation, and measurable impact in cybersecurity.

Security posture

The website exhibits a mature security posture with enforced HTTPS, privacy and cookie policies with consent mechanisms, and dedicated channels for security incident reporting. While explicit security headers are not visible in the provided data, the presence of a Security & Trust page and vulnerability disclosure programs indicates a proactive security culture. No exposed sensitive data or vulnerable libraries were detected in the analysis. The lack of a security.txt file is a minor gap. Overall, the security practices align well with industry standards for a cybersecurity platform, though some enhancements in header policies and public certification disclosures could strengthen trust further.

Recommendations

  1. Implement and publish comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  2. Publish a security.txt file at the root domain to facilitate vulnerability reporting and improve transparency.
  3. Disclose relevant security certifications and compliance frameworks (e.g., ISO 27001, SOC 2) prominently on the website to reinforce trust.
  4. Enhance incident response transparency by providing more detailed public documentation on procedures and timelines.
  5. Regularly audit and minimize third-party scripts and tracking tools to reduce potential attack surface and improve privacy compliance.

Technical notes

Notes

The website is built on Drupal CMS, utilizing modern web technologies including SVG icons, responsive CSS, and JavaScript integrations for analytics and marketing automation (Google Analytics, Google Tag Manager, Marketo, PathFactory). The site demonstrates fast loading times and excellent mobile optimization. Accessibility features such as skip links and focus-visible outlines are present, indicating attention to inclusive design. SEO is supported by proper meta tags and Open Graph data. The technical infrastructure appears robust and well-maintained, supporting a high-quality user experience for a global enterprise audience.
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.
