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

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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

G2 operates as a major player in the technology sector, focusing on B2B software review services. Its business model revolves around aggregating user-generated reviews and ratings to provide transparent insights into software products. The platform likely generates revenue through sponsored content and advertising partnerships. The target audience includes software buyers, vendors, and enterprises seeking software solutions. The company maintains a consistent brand presence and leverages extensive analytics to optimize user engagement. Despite the lack of publicly available WHOIS data, the site’s market position and content quality suggest a reputable and established business.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, presence of key security headers, and a robust cookie consent framework compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of explicit security policy or incident response contact information is a minor gap. The extensive use of third-party analytics and tracking services necessitates ongoing vigilance to maintain privacy compliance and data protection standards. Overall, the security maturity is high, suitable for a platform handling user-generated content and personal data.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency.
  2. Provide clear contact channels for security incidents, such as security@ or abuse@ email addresses.
  3. Regularly audit third-party libraries and tracking tools for vulnerabilities and privacy compliance.
  4. Enhance visibility of data protection officer contact information to comply with GDPR best practices.
  5. Maintain updated WHOIS records to improve domain trustworthiness and transparency.

Technical notes

Notes

The website uses a modern tech stack with JavaScript frameworks, asynchronous loading of analytics scripts, and advanced consent management via Osano. Performance optimizations are evident with fast loading times and mobile responsiveness. The site integrates multiple analytics platforms for comprehensive user behavior tracking. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The technical implementation supports a high-quality user experience but requires continuous monitoring of third-party dependencies to mitigate risks.
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.
