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

Halo Security is a private, woman-owned cybersecurity company founded in 2013, specializing in external attack surface management and penetration testing services. The company offers a comprehensive SaaS platform that provides security leaders with deep visibility into their internet-facing assets, helping organizations identify, assess, and remediate risks across cloud environments, third-party providers, and organizational silos. Their market position is strong, with trusted customers including SurveyMonkey and Experian, and a clear focus on B2B security solutions. Technically, the website is well-built using modern JavaScript libraries, cloud CDN hosting, and integrates multiple analytics and marketing tools such as Google Analytics, Bing UET, LinkedIn Insight, and Intercom. The site is fast, mobile-optimized, and accessible, with professional design and clear navigation. However, the absence of explicit CMS or framework details suggests a custom or proprietary platform. From a security perspective, the site enforces HTTPS and displays a TrustedSite certification badge, indicating a good baseline security posture. While no critical vulnerabilities or exposed sensitive data were detected, the lack of a public security policy or vulnerability disclosure page limits transparency. The WHOIS data is missing or unavailable, which raises concerns about domain registration legitimacy despite the professional web presence. Overall, Halo Security presents a credible and professional cybersecurity service offering with strong technical and marketing infrastructure. The main risk lies in the domain registration opacity, which should be further investigated to ensure trustworthiness. Strategic improvements in security transparency and public incident response documentation would enhance their security posture and customer confidence.

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. 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  3. 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.

Business context

Business profile

Halo Security operates in the competitive cybersecurity market, focusing on external attack surface management and penetration testing. Their business model combines SaaS platform subscriptions with manual ethical hacking services, targeting security teams and organizations requiring comprehensive external risk management. The company leverages partnerships and integrations with cloud providers and workflow tools to enhance product value. Their customer base includes medium to large enterprises, supported by a medium-sized organizational structure. The company’s private and woman-owned status, along with a founding date of 2013, positions it as an established player with growth potential. Marketing efforts are sophisticated, utilizing multiple analytics and engagement platforms. However, the lack of public WHOIS data and security policy documentation may impact trust among cautious enterprise clients.

Security posture

Halo Security demonstrates a mature security posture with HTTPS enforcement, agentless scanning technology, and integration of trusted third-party security and analytics tools. The website does not expose sensitive data and uses a TrustedSite certification to signal trust. However, the absence of a dedicated security policy, incident response plan, or vulnerability disclosure mechanism reduces transparency and may hinder rapid incident communication. No critical vulnerabilities or insecure libraries were detected in the website content. The missing WHOIS data is a notable concern, potentially indicating privacy protection or registration issues that could affect domain legitimacy. Overall, the security posture is strong but could benefit from enhanced public security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks, controls, and incident response procedures.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Verify and disclose domain registration details to improve transparency and trustworthiness.
  4. Enhance security headers explicitly (e.g., Content-Security-Policy, X-Frame-Options) and document them publicly.
  5. Maintain and update privacy and cookie policies regularly to ensure ongoing GDPR and privacy compliance.

The technical implementation is robust with no visible technical debt or performance bottlenecks. Opportunities exist to improve explicit security header implementation and public documentation of security controls.
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.
