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

Prosta Linia is a Polish digital marketing agency specializing in web development, e-commerce solutions, and Google Ads advertising. Established in 2017, the company positions itself as a Google Partner, offering professional and effective marketing services to businesses seeking to enhance their online presence. Their website demonstrates a modern WordPress-based infrastructure with SEO and user-friendly design, targeting primarily Polish-speaking clients. The agency showcases a portfolio of recent projects and emphasizes collaboration without long-term contracts, focusing on measurable marketing results. Technically, the website leverages WordPress with popular plugins such as Yoast SEO and Contact Form 7, along with Google reCAPTCHA for form security. Hosting appears to be with OVH SAS, a reputable provider. The site is mobile-optimized and includes cookie consent mechanisms, reflecting a good level of digital maturity. Analytics and tracking are implemented via Google Analytics and Google Tag Manager, supporting marketing insights. From a security perspective, HTTPS is enforced, and reCAPTCHA is used to mitigate spam. However, the site lacks explicit security headers and does not publish detailed security or incident response policies. No vulnerability disclosure or security.txt files are present, which could be areas for improvement. The domain registration data is consistent and legitimate, supporting the trustworthiness of the business. Overall, Prosta Linia presents a professional and credible online presence with solid technical foundations and marketing certifications. Enhancing security policies and transparency could further strengthen their security posture and client 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

12 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

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 · found on this site
  • 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

Prosta Linia operates in the competitive digital marketing and web development sector in Poland, targeting small to medium-sized businesses. Their Google Partner certification provides a competitive advantage, signaling expertise in Google Ads campaigns. The business model is service-oriented, focusing on delivering measurable marketing outcomes without binding long-term contracts, appealing to clients seeking flexibility. The portfolio highlights diverse industry clients, indicating adaptability and a broad market reach. The agency leverages modern web technologies and SEO best practices to maintain a strong online presence. Partnerships with Google and social media engagement via Facebook support their marketing ecosystem. Growth indicators include recent project showcases and active content updates. Strategic observations suggest opportunities in expanding security transparency and formalizing compliance documentation to meet evolving regulatory demands.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and Google reCAPTCHA protecting forms against automated abuse. Cookie consent is implemented, supporting privacy compliance. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No public security or incident response policies are found, limiting transparency for clients and partners. The lack of a vulnerability disclosure policy or security.txt file indicates a gap in proactive security communication. No vulnerabilities or exposed sensitive data were detected in the content. Regular updates of WordPress and plugins are implied but should be verified to prevent exploitation. Overall, the security posture is adequate for a small agency but could be improved by adopting additional best practices and formal policies.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  3. Publish a clear security policy and incident response plan accessible on the website to increase transparency and client confidence.
  4. Add a vulnerability disclosure policy and security.txt file to facilitate responsible reporting of security issues.
  5. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from known 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.
