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

Leftshift One is an established Austrian technology company specializing in generative AI solutions, particularly their MyGPT platform which leverages Retrieval-Augmented Generation (RAG) to provide secure, scalable, and customizable AI-powered knowledge management for enterprises and SMEs. The company positions itself as a technology leader with over 8 years of experience and 200 successful AI projects, emphasizing data privacy and compliance with GDPR. Technically, the website is built on WordPress with modern frameworks like Elementor and optimized with WP Rocket, but lacks a valid SSL certificate and proper TLS configuration, which are critical security gaps. The security posture is moderate with some vulnerabilities such as a subdomain takeover risk. Overall, the website is professional, content-rich, and compliant with privacy regulations, but requires urgent improvements in SSL/TLS security to enhance trust and protect user data.

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

11 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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 · found on this site
  • 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

Leftshift One operates in the technology sector, offering B2B SaaS and consulting services focused on AI-driven knowledge management and generative AI platforms. Their MyGPT product targets a broad range of industries including manufacturing, education, energy, banking, and healthcare. The company demonstrates strong market positioning through client logos, social media presence, and detailed product information. Their business model is based on modular, scalable AI solutions with token-based pricing, appealing to both SMEs and larger enterprises. The presence of a dedicated service subdomain and compliance checks indicates a mature and customer-focused approach. The company’s use of privacy protection in domain registration is justified given the nature of their business.

Security posture

The website’s security maturity is moderate but with notable weaknesses. While it employs security headers like X-Content-Type-Options and uses Cloudflare as a CDN, it lacks a valid SSL certificate and does not support modern TLS protocols, exposing users to potential data interception risks. A subdomain takeover vulnerability was detected on ftp.leftshift.one, which could be exploited if not remediated. The site uses secure cookie flags and has a cookie consent mechanism in place, supporting GDPR compliance. However, the absence of HSTS and OCSP stapling reduces the overall security robustness. No incident response or security policy pages were found, indicating potential gaps in transparency and readiness. Addressing these issues is critical to protect sensitive business and user data.

Recommendations

  1. Immediately install and maintain a valid SSL/TLS certificate to enable HTTPS and protect data in transit.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and 1.3) and implement HSTS to prevent protocol downgrade attacks.
  3. Mitigate the subdomain takeover vulnerability by properly configuring or removing the ftp.leftshift.one subdomain.
  4. Publish clear security policies and incident response procedures to enhance transparency and trust.
  5. Regularly audit and update security headers and cookie settings to align with best practices.
Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder and optimized using WP Rocket for performance. It integrates HubSpot forms for lead capture and uses Google Analytics and Google Tag Manager for analytics. The site is mobile-optimized and accessible with good SEO practices including comprehensive meta tags and structured data (JSON-LD). However, the lack of a valid SSL certificate and disabled TLS protocols significantly impact the security and trustworthiness of the site. Performance metrics are not fully available but the use of caching and lazy loading indicates a focus on speed. The technical stack is mature but requires urgent security upgrades to meet enterprise standards.
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.
