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

3 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

      SSL Certificate Expires Soon

      SSL certificate expires in 4 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
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • 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

Oasis holds a strong market position as a pioneer in confidential computing for blockchain, leveraging trusted execution environments and modular architecture to deliver high throughput and low fees. Their business model focuses on platform and developer tool offerings, fostering an ecosystem of privacy-centric dApps. The company demonstrates strategic partnerships with notable blockchain projects and maintains an active bug bounty program, indicating commitment to security and community trust. Growth indicators include a live mainnet (ROFL), developer demos, and multiple engagement programs. The absence of direct contact emails but presence of contact forms suggests controlled communication channels.

Security posture

The website employs HTTPS with a good SSL configuration and domain registration protections such as clientTransferProhibited status. However, DNSSEC is not enabled, and no explicit security headers were detected in the HTML content, representing areas for improvement. The presence of a bug bounty program on Immunefi is a positive security indicator. No incident response or security policy pages were found, which limits transparency. Analytics usage is moderate with Matomo, Fathom, and Google Tag Manager, but privacy compliance documentation is minimal. Overall, the security posture is solid but could benefit from enhanced DNS security, security headers, and published policies.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish clear and comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Implement and advertise a formal security policy and incident response contact information to enhance transparency.
  4. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to harden the website against common attacks.
  5. Improve accessibility features and compliance to broaden usability and meet regulatory standards.

Technical notes

Notes

The website is built on Webflow CMS, utilizing modern web fonts and asynchronous loading of analytics and tracking scripts including Matomo, Fathom, and Google Tag Manager. Hosting appears to be via Cloudflare DNS services. The site is mobile optimized with good navigation clarity and professional design. Performance is moderate, with some deferred script loading and image optimizations. No CMS vulnerabilities or outdated libraries were detected in the provided content. The technical infrastructure supports a scalable and secure platform aligned with the company's blockchain privacy focus.
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.
