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

Omise is a Thailand-based financial technology company specializing in payment solutions for global businesses and financial institutions. The company offers a comprehensive suite of services including online payment acceptance, payment links, transaction management, payment orchestration, PayFac services, acquiring technology, and professional fintech consulting. Their platform integrates AI-powered efficiency tools to enhance payment processing and revenue growth. The website is professionally designed with clear navigation and modern web technologies, hosted on Webflow with asynchronous loading of analytics and tracking scripts. Security posture is strong with HTTPS and OpenID Connect authentication, though explicit security policies and privacy compliance disclosures are missing. Overall, Omise presents a credible fintech business with a solid technical foundation but could improve transparency around privacy, cookie consent, and incident response.

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. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

  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
    • 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

Omise operates in the fintech and payment processing sector, targeting global businesses and financial institutions. Their business model revolves around providing embedded and unified payment solutions, leveraging AI to optimize efficiency. The company maintains a professional online presence with detailed product offerings and documentation. Their market position is that of a trusted payment platform with a focus on seamless cross-border transactions. The absence of explicit privacy and security policies on the main site suggests an opportunity to strengthen compliance and customer trust. The related domains indicate a well-integrated service ecosystem supporting customer onboarding, documentation, and authentication.

Security posture

The website enforces HTTPS and uses secure authentication protocols such as OpenID Connect. Analytics and tracking scripts are loaded asynchronously, reducing performance impact. However, the lack of visible security headers (e.g., CSP, HSTS) and absence of published security policies or incident response contacts represent gaps in security transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is good but could be enhanced by adding explicit security headers, publishing a security policy, and implementing vulnerability disclosure mechanisms.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance and consent mechanisms.
  2. Add explicit security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  3. Provide clear incident response and vulnerability disclosure contacts, including a security.txt file.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Maintain transparency by including data protection officer contact information and certifications.

Technical notes

Notes

The website is built using Webflow CMS and hosting, leveraging Google Fonts, Google Tag Manager, Facebook Pixel, and Lottie animations for a modern user experience. The use of OpenID Connect for authentication indicates a mature identity management approach. Performance is moderate with asynchronous script loading and mobile optimization. SEO is supported by proper meta tags and Open Graph data. Technical risks are minimal but could be reduced by improving security header implementation and accessibility compliance.
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.
