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

Mercury Financial LLC operates as a financial services provider specializing in business credit cards and related financial management tools. The company targets small to medium-sized businesses, offering digital account management through a mobile app and online platform. The website demonstrates a modern technical infrastructure leveraging Angular framework and integrates multiple third-party services for analytics, consent management, and fraud detection. Security posture is generally strong with HTTPS enforcement and bot protection via hCaptcha, though explicit security headers are not evident. Privacy compliance is supported by a comprehensive privacy and security policy and an active cookie consent mechanism. However, the absence of WHOIS registration data raises concerns about domain legitimacy, which should be further investigated. Overall, the website presents a professional and trustworthy front for its financial services, but improvements in transparency and contact information availability are recommended.

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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. 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

    • 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

  3. 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

Mercury Financial LLC appears positioned as a niche financial services provider focusing on business credit cards. The business model revolves around providing credit products and financial tools to small and medium enterprises, leveraging digital channels for customer engagement. The company maintains an active presence on major social media platforms, enhancing brand visibility and customer outreach. The integration of analytics and marketing tools suggests a data-driven approach to customer acquisition and retention. The lack of explicit contact details and WHOIS data may impact customer trust and regulatory compliance. Strategic partnerships or parent company affiliations are not evident from the data, indicating an independent operational structure.

Security posture

The website employs HTTPS and integrates bot mitigation technologies such as hCaptcha and fraud detection services like Iovation and MPSnare, indicating a proactive security stance. The presence of a cookie consent banner aligns with privacy regulations including GDPR. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Incident response and vulnerability disclosure policies are not publicly available, which could hinder timely security issue management. Enhancing these areas would strengthen the security posture and compliance readiness.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish clear incident response and vulnerability disclosure policies to improve transparency and security readiness.
  3. Provide explicit and accessible contact information including support emails and phone numbers to enhance customer trust.
  4. Verify and update WHOIS registration data to ensure domain legitimacy and regulatory compliance.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built on a modern Angular framework (version 19.2.14) with asynchronous loading of scripts and styles, indicating a contemporary single-page application architecture. Integration with Google Tag Manager, Osano Consent Management, FullStory analytics, Amazon Ads, and hCaptcha reflects a mature digital marketing and security infrastructure. Performance is moderate with some third-party scripts that may impact load times. Mobile optimization is good, supported by responsive design and app download links for Android and iOS. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. No CMS or hosting provider details were identified from the HTML content. The absence of explicit SEO meta tags and structured data limits search engine optimization potential.
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.
