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

6 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  2. 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"

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

Nexum operates primarily in the B2B technology sector, targeting corporate clients requiring custom software and online communication solutions. Their long-standing market presence and extensive project portfolio suggest competitive advantages in experience and client trust. The company leverages partnerships such as the Karrier Portál to enhance its service ecosystem. Revenue streams likely derive from software development contracts, platform licensing, and managed IT services. The dual office locations in Szeged and Budapest support regional market coverage. The business model focuses on dedicated project teams and specialized developers per domain, emphasizing quality and client-centric delivery. Growth indicators include sustained client relationships and continuous technology updates.

Security posture

The website demonstrates a baseline security maturity with HTTPS and cookie consent compliance. The contact form includes validation and privacy acknowledgment, reducing risk of data misuse. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security policies or incident response contacts represent gaps in transparency and defense-in-depth. No vulnerability disclosures or security.txt files were found, limiting external security engagement. The use of third-party scripts like Google Analytics and Tag Manager introduces moderate tracking but appears managed with user consent. Overall, the security posture is adequate for a medium-sized IT services firm but could be enhanced by formalizing policies and improving header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information to improve transparency and readiness.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen client-side protections.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting and improve security posture.
  4. Enhance accessibility features to meet higher standards and improve user inclusivity.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website is built using modern front-end technologies including Bootstrap for responsive design and CreateJS for canvas animations. Google Tag Manager and Google Analytics are integrated for marketing and analytics purposes. The site is hosted on infrastructure with a dedicated server room at BIX, indicating control over hosting environment. Performance is moderate with preloaded fonts and deferred script loading improving load times. The site is mobile optimized with clear navigation and structured content. No CMS was detected, suggesting a custom or static site architecture. Technical risks are minimal but could be reduced by adding security headers and improving 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.
