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

Clicksign is a Brazilian technology company specializing in digital and electronic document signature solutions. Their platform automates the signing process, targeting businesses and professionals primarily in Brazil and Latin America. The website is multilingual, supporting Portuguese, Spanish, and English, reflecting a regional market focus. Clicksign positions itself as a leading SaaS provider in the digital signature space with a user-friendly and secure platform. The company emphasizes automation and legal compliance in document workflows. Technically, the website is built on Webflow CMS and integrates multiple modern marketing and analytics tools including HubSpot, Microsoft Clarity, Google Tag Manager, and Visual Website Optimizer. The site is well-optimized for SEO and mobile devices, with good performance and accessibility basics. Security best practices are observed with HTTPS enforcement, reCAPTCHA integration, and cookie consent mechanisms. However, explicit security policies and incident response contacts are not published. The security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is supported by comprehensive privacy and cookie policies, including GDPR considerations. The lack of WHOIS data reduces domain trustworthiness but the professional website and marketing maturity suggest legitimate business operations. Overall, the site presents a trustworthy and professional digital signature service with room for improvement in transparency around security and contact information. Strategic recommendations include publishing a dedicated security policy and incident response information, establishing a vulnerability disclosure program, enhancing accessibility features, and maintaining regular audits of third-party scripts to mitigate risks. These steps will strengthen trust and compliance, supporting Clicksign's market position and customer confidence.

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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 25 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

Clicksign operates in the technology sector, focusing on digital signature SaaS solutions primarily for the Brazilian and Latin American markets. Their business model revolves around providing a secure, automated platform for electronic document signing, targeting businesses and professionals who require legal and efficient signature workflows. The company leverages a strong digital marketing ecosystem with integrations to HubSpot and VWO, indicating a data-driven growth strategy. The multilingual website supports expansion beyond Brazil into Spanish and English-speaking markets. While direct contact details are limited, the presence of privacy and cookie policies and marketing transparency tools reflect a mature operational approach. The absence of WHOIS data is a minor concern but does not detract significantly from the business credibility given the professional online presence and service offering.

Security posture

The website demonstrates a good security posture with HTTPS enforced and modern security headers likely in place. Use of Google reCAPTCHA protects forms from automated abuse. Cookie consent is managed via OneTrust, supporting privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the site lacks a published security policy or incident response contact information, which are important for transparency and trust. There is no evidence of a vulnerability disclosure program or security.txt file. The WHOIS data is missing, which reduces domain trust but may be due to privacy protection. Overall, the security maturity is good but could be improved by publishing explicit security governance documents and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information (e.g., security@ or abuse@ email).
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance website accessibility to meet higher compliance standards.
  5. Regularly audit and update third-party scripts and integrations to mitigate security risks.

Technical notes

Notes

The website is built on Webflow CMS, leveraging a modern tech stack including Google Tag Manager, HubSpot, Microsoft Clarity, and Visual Website Optimizer for analytics and marketing optimization. The site uses asynchronous loading of scripts to improve performance. Mobile optimization is good, and SEO meta tags are properly configured. Hosting is provided by Webflow, which typically includes HTTPS and security headers. The site performance is moderate, with some room for improvement in loading speed and accessibility features. The technical infrastructure supports a scalable SaaS platform with integrated marketing and analytics capabilities, reflecting a mature digital presence.
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.
