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.

Priority findings

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Security headers

    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.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

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

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

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.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

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

Business profile

MaxLinear operates in the semiconductor and telecommunications sectors, providing essential hardware solutions for broadband and connectivity markets. Their business model is primarily B2B, selling semiconductor products and solutions to service providers and industrial customers. The company demonstrates a clear market focus on enabling multi-gigabit connectivity across diversified markets including access, connectivity, industrial, and infrastructure. Revenue streams likely derive from product sales and licensing of semiconductor technologies. The target customer segments include telecommunications operators, enterprise infrastructure providers, and industrial market participants. The company maintains a strong partnership ecosystem, including investor relations and career platform partners, enhancing its market reach and operational capabilities. Strategically, MaxLinear positions itself as a technology leader with a comprehensive product portfolio and a focus on innovation in AI, HPC workloads, and next-generation wireless technologies. The website content and structure support this positioning with detailed product and solution information, investor resources, and career opportunities.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and a suite of security headers such as Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Content-Security-Policy, and Referrer-Policy. These measures protect against common web vulnerabilities and enhance user data security. The presence of a cookie consent mechanism compliant with GDPR indicates attention to privacy regulations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Forms appear to be secured with validation and no direct email addresses are exposed, reducing spam and phishing risks. However, the absence of a publicly available incident response contact or vulnerability disclosure policy limits transparency and may hinder rapid response to security issues. Implementing these would strengthen the security culture and compliance posture further.

Recommendations

  1. Publish explicit incident response contact information and procedures on the website.
  2. Implement and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting.
  3. Enhance security policy documentation to reference recognized frameworks such as ISO 27001 or NIST.
  4. Add contact details for a Data Protection Officer or privacy contact to improve GDPR compliance transparency.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Standards and sources

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.
