lerstudio.cz Security Report Summary

lerstudio.cz received a security score of 41 out of 100 in Guard's comprehensive security analysis, classified as "Elevated Risk". This report covers Ler digital studio s.r.o.'s website security posture. Ler digital studio s.r.o. operates in the Technology industry in Czech Republic.

Ler digital studio s.r.o. is a well-established Czech digital and branding agency founded in 2013, specializing in web development, graphic design, and online marketing services. The company targets both Czech and international clients, offering tailored digital solutions including website creation, e-commerce, branding, and marketing consultancy. Their market position is reinforced by multiple partnerships with recognized entities such as Google, Wix, Meta, and industry associations, reflecting a strong reputation and trustworthiness in the digital services sector. Technically, the website employs a modern technology stack including Laravel backend, jQuery, Bootstrap, and various front-end libraries for animations and user experience enhancements. The site is hosted by Wedos, a Czech hosting provider, and demonstrates good mobile optimization and SEO practices. Analytics and tracking tools are extensively used, including Google Analytics, Microsoft Clarity, Facebook Pixel, and retargeting services, indicating a mature digital marketing infrastructure.

Security Posture Analysis

Comprehensive Security Assessment

The website demonstrates a moderate to good security maturity level with HTTPS enforced and CSRF protection implemented. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No explicit incident response or vulnerability disclosure policies are present, which may hinder rapid response to security events. Cookie usage is transparent but lacks a consent mechanism, potentially impacting GDPR compliance. The extensive use of third-party tracking scripts increases the attack surface and privacy risks. Overall, the security posture is adequate for a digital agency but could benefit from formalized policies and enhanced technical controls.

Strategic Recommendations

Priority Actions for Security Improvement

1

Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
