Recommendations for Security Assessments for Startups at Different Growth Stages


Choosing the appropriate security assessment for a startup depends on various factors, including the company’s size, stage of development, infrastructure complexity, regulatory requirements, and available resources. Based on our experience at ESKA, where we have conducted penetration testing for hundreds of startups at different growth stages, we have formulated recommendations on the optimal types and frequency of security testing for each stage.


Early Stages (Formation and Validation)


  • Automated Vulnerability Scanning: Start with automated vulnerability scanning. This scanning can be configured for regular execution and serves as the first line of defense, identifying and fixing common vulnerabilities in the system’s infrastructure and applications with minimal effort.

  • Annual Penetration Testing: Conduct annual penetration testing from a "gray box" or "white box" perspective. Gray box testing offers a balanced approach, providing insight into potential vulnerabilities based on a certain level of internal information similar to what a potential attacker might have.

  • Certification and Compliance: Use the penetration test report to gain certifications, meet compliance objectives, or demonstrate a high level of cybersecurity to your clients.


Growth Stage


  • Increased Complexity: As the startup moves from initial development to growth, the complexity of its operations and IT systems increases, as well as the volume of processed data and market visibility.

  • Frequent Penetration Testing: Alongside vulnerability scanning, conduct penetration testing more frequently—quarterly or continuously.

  • Key Platforms Testing: Regularly test all critical platforms of the startup to avoid making the common and catastrophic mistake of neglecting penetration testing altogether.


Preparing for the First Penetration Test


Thorough preparation for the first penetration test will enhance its effectiveness and help improve the cybersecurity posture of your startup. Here's a guide to help you prepare effectively:

  1. Define the Scope:

  • Determine which parts of your network, systems, mobile, or web applications you want to test. The scope should provide a comprehensive assessment covering critical aspects of your startup's digital assets.
