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

Synack is a leading cybersecurity company specializing in Penetration Testing as a Service (PTaaS), leveraging a global community of elite security researchers and advanced AI technologies to provide continuous vulnerability discovery and risk reduction. The company holds a strong market position with FedRAMP Moderate authorization, serving enterprise clients across various industries including technology, financial services, and public sector. Their platform integrates automation with human-led testing to deliver scalable and effective security validation. Technically, Synack's website is built on WordPress with modern SEO and analytics tools such as Yoast SEO, Google Analytics, and Google Tag Manager. The site demonstrates good performance, mobile optimization, and accessibility. Security best practices are well implemented, including HTTPS enforcement, comprehensive security headers, and cookie consent mechanisms. The company maintains a professional digital presence with extensive resources, media, and social engagement. From a security posture perspective, Synack exhibits a mature security framework with certifications like FedRAMP Moderate, secure infrastructure, and no evident vulnerabilities or exposed sensitive data. However, the absence of a public security.txt file and incident response contact details suggests areas for improvement in transparency and vulnerability disclosure. Overall, Synack presents a low-risk profile with strong business credibility and security maturity. Strategic recommendations include enhancing public security disclosures, maintaining rigorous third-party script audits, and expanding incident response visibility to further strengthen trust and compliance.

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.

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Synack operates in the cybersecurity technology sector with a focus on offensive security testing services. Their business model centers on subscription-based PTaaS offerings combined with human expertise from a vetted red team. The company targets large enterprises and government sectors requiring high assurance security testing. Synack's competitive advantages include FedRAMP certification, a large global researcher community, and AI-enhanced testing capabilities. Their partnership ecosystem includes technology integrators and solution providers, supporting a comprehensive security testing platform. Growth indicators are reflected in active content marketing, webinars, and a robust resource hub. The company maintains a consistent brand and professional online presence, reinforcing market leadership.

Security posture

Synack demonstrates a high level of security maturity with enforced HTTPS, strong security headers, and compliance with privacy regulations including GDPR. The platform's FedRAMP Moderate certification underscores its adherence to stringent federal security standards. No critical vulnerabilities or exposed sensitive data were detected on the website. Security best practices such as cookie consent and secure form handling are in place. However, the lack of a publicly accessible security.txt file and incident response contact information represents a minor compliance gap. Overall, the security culture appears proactive and well-integrated with business operations.

Recommendations

  1. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  2. Provide clear incident response contact information on the website.
  3. Regularly review and update third-party scripts and analytics tools to mitigate supply chain risks.
  4. Enhance transparency around data retention policies and user privacy practices.
  5. Continue investing in AI-driven security testing innovations to maintain market leadership.

Technical notes

Notes

The website is built on a WordPress CMS platform enhanced with Yoast SEO for search optimization and Google Tag Manager for analytics management. It uses jQuery and Wistia for interactive and video content delivery. The site is mobile responsive with good accessibility features and fast loading times. Security headers and HTTPS are properly configured, contributing to a secure browsing experience. The presence of OneTrust cookie consent indicates compliance with privacy regulations. Technical risks are minimal, though continuous monitoring of third-party dependencies is advised to prevent 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.
