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

LeanOn AB is a Swedish IT company specializing in smart system solutions that digitalize the financial industry. Established in 1998, LeanOn serves major Nordic banks, stock exchanges, and niche financial firms with tailored IT products and consulting services. Their offerings include an online platform (Lisa), stock trading (LEIF), fund trading (KARL), and order record keeping (ELIN). The company positions itself as a reliable and experienced partner in fintech, emphasizing modern, secure, and user-friendly solutions. Technically, the website is built on WordPress with Bootstrap and uses popular libraries like jQuery, Google Tag Manager, Google Analytics, and Facebook SDK, indicating a mature digital infrastructure. Security-wise, the site enforces HTTPS and uses standard tracking tools but lacks explicit security headers and detailed security policies. Overall, the website is professional, well-structured, and compliant with basic privacy standards, though it could improve in security transparency and incident response readiness.

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

9 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

    • 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. 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"

    • 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';…

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

LeanOn operates in the finance sector, targeting financial institutions requiring digital transformation and automation of complex processes. Their business model is B2B, focusing on delivering scalable IT solutions and consulting. The company demonstrates strong market positioning with a long history and notable clients, as evidenced by displayed client logos and case studies. Their partnership ecosystem includes social media presence on LinkedIn and Instagram, enhancing brand visibility. Growth indicators include active job postings and continuous product development. The company maintains consistent branding and professional content, supporting credibility and trust in the fintech market.

Security posture

The website's security posture is moderate. It uses HTTPS with valid SSL, employs Google Tag Manager and Facebook SDK with appropriate async and crossorigin attributes, and avoids exposing sensitive data in the HTML. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options. No explicit security or incident response policies are found, and no vulnerability disclosure or security.txt files are present. The absence of these elements suggests room for improvement in security maturity and transparency. No critical vulnerabilities or malware indicators are detected in the provided content.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies to improve transparency and readiness.
  3. Add a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  4. Ensure all forms (if any) include CSRF protection and input validation to prevent injection attacks.
  5. Regularly audit third-party scripts and update dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built on a WordPress CMS platform using Bootstrap 3.3.7 and jQuery 3.3.1, indicating a stable but somewhat dated frontend framework. It integrates Google Tag Manager and Google Analytics for tracking, and Facebook SDK for social media features. The use of Font Awesome 5 Pro icons is extensive, loaded via CDN. The site is mobile-optimized with responsive design elements and includes SEO best practices such as meta tags, Open Graph, and JSON-LD structured data. Performance is moderate, with asynchronous loading of scripts to improve page load times. The technical stack is mature but could benefit from updating Bootstrap to a newer version and enhancing accessibility features.
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.
