Medium risk. 4 critical or high findings in Security headers and GDPR outside view.
ProvenExpert is a technology company based in Germany, operating a SaaS platform that enables businesses to collect, aggregate, and showcase customer reviews and ratings from multiple sources. The platform targets a broad audience including freelancers, SMEs, and large enterprises, offering tools such as customer surveys, rating seals, and Google star rating integration to enhance online reputation and drive revenue growth. The company has a solid market presence with over 1.2 million expert profiles and millions of reviews aggregated. Technically, the website is hosted on Google Cloud with DNS managed by Cloudflare, utilizing modern web technologies including jQuery, Bootstrap, and Cookiebot for cookie consent management. While the site is mobile optimized and SEO friendly, performance metrics indicate slow loading times, and accessibility features are basic. Security posture is weak due to the absence of a valid SSL certificate and lack of TLS protocol support, despite some security headers being present. The security evaluation highlights critical vulnerabilities such as missing HTTPS, no TLS support, and lack of HSTS enforcement, which significantly reduce the security score. Privacy compliance is good with clear privacy and cookie policies and GDPR adherence. Business credibility is strong with clear company information, testimonials, and trust seals. Overall, the website is professional and trustworthy but requires urgent security improvements to protect user data and maintain compliance. Strategically, the company should prioritize SSL/TLS certificate installation and configuration, enhance security headers, and optimize site performance to improve user experience and security posture. Continued focus on privacy compliance and transparent communication will support sustained trust and growth.
Scanned
NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.
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
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.
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.
Risk levels
Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.
Leaked records that mention provenexpert.net, from OffSeq Breach.
No leaked records found
Breach holds no records for provenexpert.net right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.
Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
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.
