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

Certora is a technology company specializing in formal verification tools and smart contract audits aimed at securing blockchain applications. Their flagship product, Certora Prover, offers mathematical certainty in smart contract behavior, targeting developers and enterprises in the decentralized finance (DeFi) sector. The company positions itself as a leader in the smart contract security market, serving high-profile clients and protecting over $100 billion in total value locked (TVL). Technically, the website is built on modern frameworks such as Next.js and React, hosted on Vercel, and uses Prismic as a CMS. The site demonstrates excellent design, mobile optimization, and SEO practices. Analytics are implemented via Vercel's own tools, with minimal user tracking observed. However, explicit cookie consent mechanisms are absent. From a security perspective, the site enforces HTTPS and shows no visible vulnerabilities or exposed sensitive data. However, security headers like CSP or HSTS are not detected, and no public security or incident response policies are published. The absence of WHOIS data limits domain trust analysis, though the website content and business indicators suggest legitimacy. Overall, Certora presents a professional and trustworthy online presence with strong technical and business foundations. Strategic improvements in security headers, privacy compliance, and transparency around incident response would enhance their security posture and user trust.

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. 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

  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.

Technical appendix

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

Business context

Business profile

Certora operates in the blockchain security niche, focusing on formal verification and audits for smart contracts. Their competitive advantage lies in offering mathematical certainty through their Prover tool and a dedicated audit team. The business model combines software tools with professional services, targeting DeFi platforms and blockchain developers. Partnerships with major DeFi projects and a community-driven approach via audit contests strengthen their ecosystem. The company shows growth potential given the increasing demand for secure smart contracts. However, lack of publicly available company registration and contact details may limit some trust aspects.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no evident vulnerabilities in the frontend. The use of formal verification tools internally suggests a strong security culture. However, the absence of security headers and public incident response information indicates areas for improvement. No security.txt or vulnerability disclosure policy is found, which could hinder coordinated vulnerability reporting. Privacy compliance is good but could be enhanced with explicit cookie consent. Overall, the security posture is solid but not fully comprehensive.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Add a clear cookie consent banner and detailed cookie policy to improve privacy compliance.
  3. Publish a dedicated security policy and incident response plan accessible on the website.
  4. Create and maintain a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  5. Enhance transparency by providing verified contact information and company registration details.

Technical notes

Notes

The website leverages a modern tech stack including React and Next.js, hosted on Vercel with Prismic CMS integration. Performance is fast with good mobile responsiveness and accessibility. SEO is well implemented with comprehensive meta tags and Open Graph data. Analytics usage is minimal and privacy-conscious. No outdated or vulnerable libraries are detected. The site architecture supports scalability and maintainability. Technical risks are low, but adding security headers and privacy mechanisms would further strengthen the infrastructure.
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.
