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.
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.

Missing Strict-Transport-Security header

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.

Business context
Business profile
JERA operates in the technology sector with a niche in financial accounting software interfaces for e-commerce. Their business model revolves around software development, licensing, and support services. They target e-commerce merchants, tax consultants, and ERP users. The company maintains partnerships with recognized financial software providers and participates in industry events, indicating active market engagement. The recent acquisition by JTL suggests growth and strategic alignment with a larger software ecosystem. Revenue streams likely include software sales, licensing fees, support contracts, and training services. Their digital presence is professional and consistent, supporting credibility and customer trust.
Security posture
The website demonstrates a mature security posture with enforced HTTPS, cookie consent compliant with GDPR, and no visible exposure of sensitive data. The use of updated WordPress core and plugins reduces vulnerability risks. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or security policy pages were found, which could enhance transparency and preparedness. Overall, the security posture is good but could be strengthened by publishing dedicated security policies and implementing additional HTTP headers.
Recommendations
Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
Publish a dedicated security policy and incident response contact information to improve transparency and trust.
Maintain regular updates of WordPress core and plugins to mitigate vulnerabilities.
Consider conducting periodic security audits and penetration testing to proactively identify and remediate risks.
Enhance accessibility features to improve compliance and user experience for all visitors.

It uses jQuery 3.6.0 and integrates Google Analytics via gtag.js. The site is mobile optimized with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate with some custom CSS and JavaScript for UI enhancements. Hosting provider details are not explicit. The technical stack is modern and well-maintained, supporting a professional online presence with room for optimization in security headers and accessibility.
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.
