Risk levelLow

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

Simera Sense is a specialized technology company focused on developing satellite imaging cameras and optical payload solutions for nanosatellite Earth observation. The company positions itself as a leader in providing medium to high-resolution imaging solutions tailored for Cubesats, micro-, and small satellites. Their website reflects a professional and consistent brand image, targeting organizations involved in space-based imaging and Earth observation. The business model is B2B, offering hardware and software solutions to enhance space imaging capabilities. Technically, the website is built on WordPress with Elementor and integrates modern marketing and analytics tools such as HubSpot, Microsoft Clarity, and Google Analytics. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. Security-wise, the site uses HTTPS and implements a cookie consent banner, but lacks visible security headers and published security policies. The domain registration is consistent and mature, enhancing trust. However, the absence of a privacy policy and terms of service pages indicates compliance gaps.

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

4 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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

Simera Sense operates in the niche technology sector of satellite imaging and optical payloads for nanosatellites. Their competitive advantage lies in offering advanced, compact imaging solutions that enable frequent and high-resolution Earth observation. The company targets space agencies, research institutions, and commercial satellite operators. Their website content and structured data emphasize innovation and leadership in optical payloads. The use of HubSpot and other marketing tools suggests active lead generation and customer engagement strategies. The company appears to be small-sized, founded in 2017, with a clear focus on technological innovation and sustainable decision-making through enhanced imaging. No parent or subsidiary companies are identified. The LinkedIn presence supports professional networking and brand visibility.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS enabled and a cookie consent mechanism in place, supporting GDPR compliance efforts. However, the lack of DNSSEC, security headers (such as CSP, X-Frame-Options), and absence of published security or incident response policies limit the security maturity. No vulnerability disclosures or security.txt files are found, which could hinder responsible vulnerability reporting. The use of third-party analytics and marketing scripts introduces potential privacy and security risks if not properly managed. Overall, the site is secure enough for general business use but would benefit from enhanced security controls and transparency.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Enable DNSSEC for the domain to enhance DNS security and prevent spoofing.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder, leveraging popular SEO and marketing plugins like All in One SEO and HubSpot integrations. The tech stack includes Google Fonts, Microsoft Clarity for user behavior analytics, and Google Analytics for traffic analysis. The site uses responsive design techniques and lazy loading for images, contributing to moderate performance. Hosting is via GoDaddy, with domain registration dating back to 2017, indicating a stable online presence. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to reduce attack surface. The site’s SEO is well-optimized with proper meta tags and structured data. Overall, the technical infrastructure is solid but can be improved with enhanced security and accessibility measures.
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.
