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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: ms60554623.msv1.invalid

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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

Lob operates in the technology sector, focusing on B2B SaaS solutions for direct mail marketing automation. Their business model leverages API-driven services and a print delivery network to streamline traditional mail campaigns at scale. The company targets medium to large enterprises seeking to integrate direct mail into omnichannel marketing strategies. Their competitive advantages include seamless integration capabilities, advanced targeting, and real-time analytics. The presence of multiple industry awards and testimonials underscores their market credibility. Lob's ecosystem includes partnerships with marketing automation and analytics providers, enhancing their platform's value proposition. Growth indicators include a large customer base and continuous product updates. Strategic observations suggest Lob is well-positioned to capitalize on the resurgence of direct mail marketing with a digital-first approach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security-related pages available. Privacy and cookie policies comply with GDPR standards, supported by a OneTrust consent mechanism. Form validation restricts non-business email domains, reducing spam and abuse risk. Tracking and analytics scripts are used responsibly with privacy considerations. However, the absence of a public vulnerability disclosure program or security.txt file limits transparency. No exposed sensitive data or known vulnerabilities are evident from the HTML content. Incident response contact information is not explicitly provided, which could be improved to enhance trust and readiness. Overall, the security maturity is good but could benefit from additional public-facing security governance documentation.

Recommendations

  1. Publish a vulnerability disclosure policy or security.txt file to improve transparency and encourage responsible reporting.
  2. Provide clear incident response contact information on the security or contact pages.
  3. Document and publicly share security headers and SSL/TLS configuration details to demonstrate best practices.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and maintain compliance.
  5. Enhance user education on data protection and privacy practices through accessible website content.

Technical notes

Notes

The website is built on a modern technology stack including Webflow CMS, JavaScript frameworks, and integrates multiple marketing and analytics tools such as Marketo, Amplitude, Clearbit, and Microsoft Clarity. Hosting appears to be via Webflow's CDN, ensuring fast performance and global availability. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well-implemented with comprehensive meta tags, Open Graph data, and structured JSON-LD schema. Form handling uses Marketo forms with client-side validation to ensure data quality. The technical infrastructure supports scalability and integration with enterprise marketing ecosystems. Opportunities exist to reduce technical debt by consolidating tracking scripts and enhancing security header configurations.
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.
