0–100, higher is better. How it is calculated

SiteLock is a leading global provider of website security solutions, founded in 2008 and operating under parent company Sectigo Limited. The company specializes in affordable and accessible cybersecurity services tailored primarily for small to medium-sized businesses and e-commerce platforms. Their offerings include comprehensive website scanning, automated malware removal, vulnerability patching, web application firewall, content delivery network, and reliable website backup solutions. SiteLock protects over 12 million websites worldwide, positioning itself as a top cybersecurity company in Arizona and beyond. Technically, SiteLock's website is built using modern frameworks such as Vue.js and Tailwind CSS, with integration of advanced security and privacy tools including Google reCAPTCHA Enterprise and Cookiebot for consent management. The site is hosted behind Cloudflare, providing robust CDN and WAF capabilities, ensuring fast performance and strong security posture. The website demonstrates excellent mobile optimization, accessibility, and SEO practices, reflecting a mature digital infrastructure. From a security perspective, SiteLock enforces HTTPS, employs multiple security headers, and integrates advanced bot detection and user verification mechanisms. The company maintains a comprehensive cookie policy with explicit user consent mechanisms, aligning with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the website content. However, explicit security policy and incident response contact information are not publicly detailed, representing an area for improvement. Overall, SiteLock presents a high level of business credibility, technical sophistication, and privacy compliance. The extensive use of third-party analytics, marketing, and retargeting tools is transparently disclosed, supporting good advertising transparency. The domain registration details are consistent with the company's public claims, reinforcing trustworthiness. Strategic recommendations include enhancing visible security certifications, publishing detailed security and incident response policies, and maintaining up-to-date privacy and cookie disclosures.

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

2 findings rated critical or high. Fix these first.

  1. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

SiteLock operates in the competitive website security market, focusing on small to medium businesses and e-commerce sites. Its subscription-based model offers tiered plans (Basic, Pro, Business) with annual and monthly billing options, targeting budget-conscious to high-traffic websites. The company leverages a strong partnership ecosystem including Sectigo Limited and various security and certificate providers. SiteLock's market position is reinforced by its protection of over 12 million sites globally and its reputation as a top cybersecurity firm in Arizona. The business benefits from diversified revenue streams including malware scanning, removal, firewall services, and backup solutions. Its strategic use of marketing and analytics tools supports customer acquisition and retention. The company’s digital presence is professional, consistent, and rich in relevant content, supporting strong brand recognition and trust.

Security posture

SiteLock demonstrates a mature security posture with enforced HTTPS, integration of Google reCAPTCHA Enterprise for bot mitigation, and use of Cloudflare's WAF and CDN services. The website employs comprehensive cookie consent management via Cookiebot, ensuring GDPR compliance. Security headers and best practices are implied through technical implementations. No critical security issues or vulnerabilities were identified in the website content. However, the absence of a publicly accessible security policy and incident response contact details suggests room for improvement in transparency and readiness. The extensive use of third-party tracking and advertising services is well disclosed, but requires ongoing monitoring to maintain privacy compliance. Overall, SiteLock's security maturity is high, supporting its role as a trusted website security provider.

Recommendations

  1. Publish a dedicated security policy page detailing security frameworks and practices.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance visibility of security certifications and compliance badges on the website.
  5. Regularly review and update privacy and cookie policies to reflect evolving regulations.

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.
