Low risk. 3 critical or high findings in GDPR outside view and SSL/TLS.
The website www.memorysafety.org represents Prossimo, an initiative by the Internet Security Research Group (ISRG) focused on advancing memory safety in critical Internet infrastructure software. The organization operates as a non-profit, supported by major technology funders such as Google, AWS, Cisco, and Cloudflare. Their key services include developing memory safe versions of widely used software components like TLS libraries, DNS resolvers, and Linux kernel drivers. The site targets developers, security professionals, and organizations interested in improving Internet security through safer code practices. Technically, the website is built using the Hugo static site generator with Bootstrap and modern JavaScript libraries, delivering a fast, mobile-optimized, and accessible user experience. The site includes comprehensive metadata and Open Graph tags, enhancing SEO and social sharing. However, no analytics or tracking scripts were detected, indicating a privacy-conscious approach. From a security perspective, the site uses HTTPS and shows no signs of exposed sensitive data or vulnerable libraries. However, it lacks explicit security headers and a cookie consent mechanism, which are recommended for enhanced security and privacy compliance. The WHOIS data is unavailable due to a malformed response, but the website's legitimacy is supported by its association with ISRG and reputable funders. Overall, the website demonstrates a strong security posture and professional presentation, with minor recommendations to improve security headers and privacy compliance. The domain's WHOIS privacy protection is justified given the non-profit nature of the organization.
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.
3 findings rated critical or high. Fix these first.
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires clear information about cookie usage
What to do: Add a dedicated cookie policy explaining cookie usage and purposes
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
SSL certificate uses 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

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.

No leaked records found
Breach holds no records for memorysafety.org 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.
