Center for Internet Security · Non-profit · United States
Low risk. 2 critical or high findings in Email security and SSL/TLS.
The Center for Internet Security (CIS) is a reputable nonprofit organization dedicated to improving cybersecurity for public and private entities by leveraging a global IT community. Their website reflects a professional and well-structured digital presence, offering resources, collaboration opportunities, and cybersecurity best practices. The organization targets IT professionals, businesses, and government agencies seeking to enhance their security posture. Technically, the website employs modern web technologies including Vue.js, jQuery, and Sitecore CMS, supported by analytics and marketing tools such as Matomo, Cookiebot, and Optimizely. The site is mobile-optimized, accessible, and SEO-friendly, indicating a mature digital infrastructure. From a security perspective, the site enforces HTTPS, uses cookie consent mechanisms, and integrates privacy-compliant analytics. No critical vulnerabilities or exposed sensitive data were detected. However, explicit security headers should be verified and a security.txt file could enhance vulnerability disclosure. Overall, CIS presents a low-risk profile with strong business credibility and compliance posture. Strategic recommendations include enhancing security header implementation, formalizing vulnerability disclosure, and continuous monitoring of third-party scripts to maintain security integrity.
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.
2 findings rated critical or high. Fix these first.
SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.
DKIM selector 'k1' uses 216-bit key
What to do: Use at least 2048-bit RSA keys for DKIM
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.

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.
