Risk levelLow

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

Dealum is a technology company founded in 2016 that provides a SaaS platform focused on managing applications, increasing investor engagement, and facilitating co-investment. The website presents a professional and modern design, leveraging Angular framework and integrating analytics tools such as Microsoft Clarity and Google Tag Manager. The technical infrastructure is supported by Cloudflare DNS services, ensuring reliable hosting and domain management. Security posture is adequate with HTTPS enabled and domain transfer protections, but lacks advanced security headers and explicit security policies on the website. Privacy compliance is weak due to absence of privacy and cookie policies, which should be addressed to meet regulatory standards. Overall, the website is accessible, well-structured, and targets investors and startups seeking streamlined investment management solutions.

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 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

    • 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

Dealum operates in the technology sector, targeting a niche market of investors and startups. Its business model revolves around providing a SaaS platform that simplifies application management and investor collaboration. The company appears to be small-sized with a consistent brand presence and a clear value proposition. The domain age and registration details align with the company's founding year, supporting credibility. While no explicit partnerships or subsidiaries are identified, the platform integrates common analytics and tracking services to support marketing and user engagement. The absence of detailed contact information and compliance documentation suggests areas for operational improvement.

Security posture

The website enforces HTTPS and uses Cloudflare DNS, which are positive security indicators. The domain status clientTransferProhibited adds protection against unauthorized transfers. However, the lack of DNSSEC and missing security headers such as Content-Security-Policy and X-Frame-Options reduce the overall security robustness. No vulnerability disclosures or incident response contacts are published, limiting transparency in security management. The presence of tracking scripts indicates moderate user data collection, but privacy policies are missing, which is a compliance gap. Overall, the security posture is moderate but can be significantly improved by implementing recommended security headers, publishing privacy and security policies, and enabling DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Provide clear contact information including security incident response contacts to improve trust and compliance.

Technical notes

Notes

The website is built using Angular framework with modern CSS and font technologies, ensuring a responsive and visually appealing user experience. Hosting is managed via Cloudflare DNS, providing performance and security benefits. Analytics integration includes Microsoft Clarity and Google Tag Manager, supporting user behavior insights. The site demonstrates good SEO practices with appropriate meta tags and Open Graph data. However, the absence of CMS identification suggests a custom or proprietary platform. Performance is moderate with asynchronous loading of scripts. Accessibility features are basic but present. Technical debt appears low, but security enhancements and privacy compliance require attention to reduce operational risks.
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.
