Medium risk. 4 critical or high findings in Security headers and GDPR outside view.
SSE – Secure Systems Engineering GmbH is a specialized IT security consultancy based in Germany, founded in 1995. The company offers a comprehensive range of services including defensive security, offensive security, and training & awareness, targeting enterprises and organizations seeking to improve their IT security posture. Their market position is that of a boutique consultancy with deep expertise in both research and practical security engineering, supported by a professional team with detailed public profiles and active contributions to the security community. Technically, the website is built on a modern React and Next.js stack, optimized for performance and mobile responsiveness. The content is well-structured, professionally designed, and SEO optimized. The company maintains a professional digital presence with active social media channels and a regularly updated blog. However, some technical improvements such as enabling DNSSEC and adding cookie consent mechanisms could enhance compliance and security. From a security perspective, the website uses HTTPS and follows good practices by not exposing sensitive data or vulnerable libraries. The absence of explicit security policies and incident response contacts is a minor gap. The domain registration data is consistent and trustworthy, with a long-established domain age and no privacy protection, aligning well with the company's claims. Overall, SSE demonstrates a strong security posture and business credibility with room for minor improvements in privacy compliance and security transparency. The website is safe, professional, and trustworthy, making it suitable for its target audience.
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 securesystems.de, from OffSeq Breach.
No leaked records found
Breach holds no records for securesystems.de 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.
Automated reading of the public site. Ratings are indicative.
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.
