Ionis Pharmaceuticals, Inc · Healthcare · United States
Medium risk. 4 critical or high findings in SSL/TLS and Security headers.
Ionis Pharmaceuticals, Inc is a well-established biopharmaceutical company specializing in RNA- and DNA-targeted medicines aimed at treating serious diseases. The company holds a strong market position with a comprehensive pipeline and a focus on innovation, patient advocacy, and corporate responsibility. The website reflects a mature digital presence with professional design, clear navigation, and relevant content targeting patients, medical professionals, investors, and healthcare stakeholders. Technically, the site is built on Drupal 11, uses Cloudflare DNS, and integrates Google Tag Manager for analytics, indicating a modern infrastructure with moderate performance and excellent mobile optimization. Security posture is good with HTTPS enabled and domain transfer protections, though DNSSEC is not enabled and security headers are not evident. Privacy compliance is moderate due to the presence of cookie consent but absence of explicit privacy and terms of service pages. Overall, the domain registration data supports the legitimacy and trustworthiness of the business.
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.
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 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key
Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.
Forces HTTPS connections
What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application

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.

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

No leaked records found

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.
