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

Clinch operates as an advanced AI-driven SaaS platform specializing in omnichannel advertising campaign management and optimization. Their flagship product, Flight Control, centralizes and automates the entire campaign lifecycle, targeting brands, agencies, publishers, and data partners globally. The company positions itself as an innovative leader with a strong client base of major global brands, offering services such as creative automation, campaign strategy building, omnichannel ad serving, and creative intelligence analytics. Technically, the website is built on modern web technologies including Webflow CMS, HubSpot marketing and analytics tools, Google Fonts, and GSAP for animations. The site is well-optimized for performance, mobile responsiveness, and SEO, reflecting a mature digital infrastructure. Security practices include HTTPS enforcement and secure form validation, though explicit security headers and incident response information are absent. From a security perspective, the site demonstrates a solid posture with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanisms. However, the absence of a vulnerability disclosure policy and security contact details suggests room for improvement in transparency and incident readiness. Overall, the website reflects a professional, trustworthy, and technically sound business presence with strong branding and global reach. The lack of WHOIS data due to privacy protection is typical for tech SaaS companies and does not detract from the site's legitimacy. Strategic recommendations include enhancing security headers, publishing incident response and vulnerability disclosure information, and expanding direct contact options for security and privacy inquiries.

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 Policy found

      GDPR requires clear information about cookie usage

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

  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

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

Clinch holds a competitive position in the AI-powered advertising technology market, leveraging automation and data-driven insights to streamline campaign management. Their SaaS model targets a broad spectrum of marketing stakeholders, emphasizing productivity and efficiency gains. The company’s global client roster and testimonial endorsements indicate strong market acceptance and brand trust. Revenue streams likely derive from subscription-based SaaS licenses and professional services. The integration with HubSpot and use of advanced web technologies reflect a digitally mature operation. Strategic partnerships and a focus on creative and media unification provide a competitive advantage. Growth indicators include expanding client logos and continuous content updates. The absence of direct contact emails or phone numbers suggests a controlled lead generation approach via forms.

Security posture

The security maturity level of the website is moderate to high. HTTPS is enforced, and forms include client-side validation to prevent malformed inputs. The presence of cookie consent aligns with privacy regulations such as GDPR. However, the lack of visible security headers like Content-Security-Policy and absence of a published security policy or incident response plan indicate gaps in security transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not publish a vulnerability disclosure or security.txt file, which could improve security culture and incident handling. Overall, the security posture is adequate for a SaaS marketing platform but could be enhanced with additional security best practices and clearer communication of security policies.

Recommendations

  1. Implement and publish comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Create and make publicly available an incident response plan and security contact information to improve transparency and readiness.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance privacy compliance by providing explicit data retention policies and more detailed contact options for data protection inquiries.
  5. Regularly audit and update third-party scripts and integrations to minimize risk from external dependencies.

Technical notes

Notes

The website is built using Webflow CMS, leveraging HubSpot for marketing automation, analytics, and form handling. It uses modern front-end technologies including Google Fonts and GSAP for animations, ensuring a visually appealing and responsive user experience. Hosting is provided by Webflow, which offers reliable performance and HTTPS by default. The site loads quickly and is optimized for mobile devices. The integration of multiple external scripts is managed well, though continuous monitoring for vulnerabilities in third-party libraries is recommended. The technical infrastructure supports the business model effectively, with opportunities to improve security headers and incident response capabilities.
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.
