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

Unisender is a well-established Russian email marketing service founded in 2009, serving over 870,000 companies primarily in Russia and Belarus. The platform offers a comprehensive suite of marketing tools including email campaigns, chat-bots, SMS messaging, landing page creation, and automation features. The website is professionally designed, content-rich, and targets businesses and marketers seeking efficient communication solutions. Technically, the site is hosted on Yandex Cloud and built on WordPress, utilizing common JavaScript libraries and marketing SDKs. However, a critical security gap exists due to the absence of a valid SSL certificate and HTTPS support, which significantly impacts the site's security posture. Privacy and cookie policies are present and indicate GDPR compliance, though user tracking is extensive. Overall, the business demonstrates strong credibility and market presence but must urgently address security vulnerabilities to protect user data and maintain 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

7 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. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Unisender holds a strong position in the Russian-speaking email marketing sector, leveraging a SaaS model with tiered pricing and free trial offerings. Its competitive advantages include a broad feature set, localized hosting within Russia, and a large client base. The company actively engages users through educational content, community channels, and multiple social media platforms. Partnerships with affiliate networks and helpdesk providers enhance its marketing and support capabilities. The business model focuses on recurring revenue from subscription plans and value-added services such as personalized consulting. Growth indicators include active content marketing, extensive integrations, and participation in innovation clusters like Skolkovo.

Security posture

The current security posture is weak due to the lack of HTTPS and valid SSL certificates, exposing users to potential data interception and undermining trust. No security headers or advanced TLS configurations are detected, and session security features are absent. While no immediate vulnerabilities like Heartbleed or POODLE are found, the missing encryption is a critical flaw. Privacy policies are comprehensive, but extensive tracking scripts raise concerns about user data privacy. Incident response and vulnerability disclosure mechanisms are not evident on the site. The company should prioritize securing its web infrastructure, implementing modern cryptographic standards, and enhancing transparency around data protection and incident handling.

Recommendations

  1. Urgently deploy a valid SSL/TLS certificate and enforce HTTPS site-wide to secure user communications.
  2. Implement security headers such as HSTS, Content Security Policy, and X-Frame-Options to mitigate common web attacks.
  3. Establish and publish an incident response policy and vulnerability disclosure program to improve security transparency.
  4. Review and optimize third-party tracking to balance marketing needs with user privacy and GDPR compliance.
  5. Enhance accessibility features and conduct regular security audits to maintain a robust security culture.

Technical notes

Notes

The website uses a mature technology stack centered on WordPress with popular JavaScript libraries for UI components and marketing integrations. Hosting on Yandex Cloud provides regional performance benefits but requires improved security configurations. The site has a large number of resources and a high page size, contributing to slow load times. SEO and mobile optimization are well addressed, with proper meta tags and responsive design. However, the lack of HTTPS and security headers introduces significant risk. Technical debt is evident in outdated or missing security practices, which could impact business continuity and user trust if not remediated promptly.
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.
