Who we are

Founded in 2020 by an ethical hacker and a former CTO, Iterasec has grown into one of the leading CREST-accredited penetration testing companies in Ukraine and Poland. We specialize in high-impact, in-depth security testing – from web and mobile applications to complex infrastructures, IoT, automotive systems, networks, and cloud environments.

We don’t just pentest. We think like attackers: going beyond industry checklists, combining human expertise with AI-augmented analysis, and delivering real security value even in compliance-driven engagements.

Our team is our core differentiator. We’ve built and retained one of the strongest penetration testing teams in the region – and every engagement reflects that depth.

Our clients range from fast-moving startups to Fortune 500 giants and world-renowned automotive and cloud companies. We simulate real-world threats and surface what automated tools and conventional testing consistently miss.

Our principles

Human-centric management

Cybersecurity is a very dynamic and complex area. Giving enough freedom, providing space for professional development, and taking good care of employees are essential to succeed as a cybersecurity company.

Always look deeper

Our teams find juicier and more impactful/non-ordinary cybersecurity issues than other vendors. We try to focus on what’s essential and practical rather than just blindly ticking the checklist boxes.

Listen to clients

Understand what the client really needs, underpromise, and overdeliver. That’s the essence of our approach to dealing with our clients.
