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

Developer Express Inc. operates a professional website offering a comprehensive suite of UI controls, frameworks, and developer tools targeting software developers across multiple platforms including desktop, web, and mobile. The company positions itself as a leading provider of .NET UI controls and related development productivity tools, with a strong market presence and a product portfolio that spans multiple technologies such as WinForms, ASP.NET, MVC, Blazor, and JavaScript frameworks. The website reflects a mature digital presence with well-structured content and modern design elements. Technically, the website employs a modern technology stack including ASP.NET WebForms, JavaScript libraries, Google Tag Manager, and Matomo analytics, alongside a cookie consent mechanism powered by OneTrust. The site is mobile optimized and accessible, with good SEO practices evident from meta tags and structured data. Performance is moderate, with room for improvement in security headers and explicit privacy disclosures. From a security perspective, the site enforces HTTPS and uses cookie consent tools, but lacks explicit security headers and a published security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data for the domain raises some concerns about domain registration transparency, though the professional nature of the website and its content suggests legitimacy. Overall, the website presents a low risk profile with strong business credibility and technical maturity. Strategic recommendations include enhancing security headers, publishing clear privacy and security policies, and improving transparency around data protection and incident response to further strengthen trust and compliance.

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

1 finding rated critical or high. Fix these first.

  1. 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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

DevExpress holds a strong position in the software development tools market, focusing on providing UI controls and frameworks for .NET and JavaScript developers. Their business model centers on software product sales and subscriptions, targeting professional developers and enterprises. The company benefits from a broad product portfolio, including multi-platform UI controls, reporting tools, business intelligence dashboards, and productivity extensions like CodeRush. The website indicates a large, established company with a history dating back to 1998, though domain registration details are not publicly available. The ecosystem includes support centers, documentation, localization services, and community engagement through blogs and events. The company’s strategic focus on cross-platform development and AI-powered extensions positions it well for future growth in developer productivity tools.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and cookie consent mechanisms in place. However, it lacks several recommended security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options, which could enhance protection against common web attacks. There is no publicly available security policy or incident response contact information, which limits transparency and preparedness for security incidents. No vulnerabilities or sensitive data exposures were detected in the site content. The absence of WHOIS data for the domain is a notable gap in domain trust verification but does not directly impact website security. Overall, the security maturity is adequate but could be improved by adopting best practices in security headers, publishing vulnerability disclosure policies, and providing clear incident response channels.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a comprehensive security policy page detailing security practices, data protection measures, and incident response procedures.
  3. Provide explicit contact information for security incidents, including dedicated security or abuse email addresses.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance privacy transparency by publishing a detailed privacy policy and GDPR compliance statements.

Technical notes

Notes

The website is built on a mature technology stack leveraging ASP.NET WebForms and modern JavaScript frameworks, supported by Google Tag Manager and Matomo for analytics. The use of OneTrust for cookie consent indicates attention to privacy compliance. The site is well-structured with comprehensive meta tags and Open Graph data supporting SEO and social sharing. Performance is moderate, with potential improvements in loading speed and optimization. Accessibility features are present, contributing to a good user experience across devices. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not discernible from the content. Overall, the technical infrastructure supports a professional and scalable web presence with opportunities for security and performance enhancements.
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.
