The website demonstrates a mature digital presence with professional design, clear navigation, and integration of modern marketing and analytics tools such as HubSpot and Google Tag Manager.

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

5 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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
  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain staging.iugu.com points to unregistered service staging-iugu-676780641.sa-east-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

iugu operates in the finance and technology sectors, offering services that include automated recurring billing, revenue splitting among subaccounts, customizable and transparent checkout experiences, and support for multiple payment methods including Pix, credit cards, and boleto bancário. The company leverages partnerships and integrations, as evidenced by displayed partner logos and related domains for billing, support, and developer resources. The business model is SaaS-based fintech infrastructure, targeting medium-sized enterprises and e-commerce platforms in Brazil. The use of HubSpot CMS and marketing automation indicates a focus on inbound marketing and customer engagement. The company maintains a professional brand image with consistent messaging and trust signals such as privacy policies and secure contact forms.

Security posture

The website employs HTTPS with an excellent SSL configuration, uses secure form handling via HubSpot, and integrates tracking and marketing pixels with user consent mechanisms. However, there is no explicit security policy or incident response contact information published, and no vulnerability disclosure program or security.txt file is found. Security headers are not explicitly visible in the HTML but may be configured at the server level. No vulnerabilities or exposed sensitive data were detected in the content. Recommendations include publishing detailed security policies, incident response procedures, and establishing a vulnerability disclosure channel to enhance transparency and trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Add incident response contact information and establish a formal incident response process.
  3. Implement and document security headers explicitly, including CSP, X-Frame-Options, and X-Content-Type-Options.
  4. Consider creating a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Verify and update WHOIS domain registration information to improve trust and transparency.

Technical notes

Notes

The website is built on HubSpot CMS, leveraging HubSpot's marketing and analytics tools, Google Tag Manager, and Facebook Pixel for tracking and advertising. The front-end uses modern JavaScript libraries such as Splide.js for carousels and Prism.js for syntax highlighting. The site is mobile-optimized with responsive design and good SEO metadata. Performance is moderate, with asynchronous loading of CSS and scripts to improve load times. Accessibility features are basic but present. No major technical debt or outdated technologies were detected. Hosting provider details are not explicitly found. Overall, the technical infrastructure supports a professional and scalable fintech platform.
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.
