Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.
The Software Engineering Institute's CERT Division, hosted under the domain insights.sei.cmu.edu, is a leading cybersecurity research and operational organization affiliated with Carnegie Mellon University. It provides advanced cybersecurity services including vulnerability research, incident response, workforce development, and risk management. The division collaborates extensively with government, industry, law enforcement, and academia to enhance cybersecurity resilience. The website reflects a mature, professional digital presence with comprehensive content, leadership profiles, case studies, and vulnerability disclosures, positioning it as a trusted authority in cybersecurity. Technically, the website employs modern web technologies such as Vue.js, MathJax, and Font Awesome, and integrates analytics tools like Google Tag Manager and Silktide Analytics. The site is mobile-optimized, accessible, and SEO-friendly, though performance is moderate. Security posture is strong with HTTPS enforced and secure forms, but could be improved by adding security headers and explicit cookie consent mechanisms. Privacy compliance is supported by a comprehensive privacy policy linked from the main SEI site. Overall, the security posture is robust with no detected vulnerabilities or exposed sensitive data. The lack of WHOIS data for the subdomain is typical and not concerning given the affiliation with Carnegie Mellon University. The site maintains high trustworthiness and professionalism, with clear contact information and active social media engagement. Strategically, the CERT Division should enhance privacy compliance by implementing cookie consent banners and publish explicit security policies or security.txt files to facilitate vulnerability reporting. These steps will further strengthen user trust and regulatory compliance.
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.
4 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.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
SSL certificate uses 384-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.
