Transformer cybersecurity in sustainable competitive advantage
We embed security from design to deployment, protecting your operations without slowing your growth.

We combine deep security expertise with an agile, product-driven mindset to raise your cyber maturity and turn it into a growth accelerator.
At Theodo, we help clients turn cybersecurity into a strategic driver for growth. As cyberattacks become more frequent and regulations such as NIS2 and DORA become stricter, we embed security throughout the entire product lifecycle.
This integrated approach enhances cyber maturity by increasing resilience to incidents, building greater trust with clients and partners, lowering costs through early vulnerability detection, and maintaining rapid delivery to accelerate time-to-market.

Our teams combine advanced cybersecurity expertise with an agile, product-focused mindset shaped by the Lean Tech® framework.
We are proficient in leading security standards and methodologies—including Zero Trust, MITRE ATT&CK, and industrialized DevSecOps—and offer comprehensive coverage across governance and compliance (ISO 27001, HDS), penetration testing, cloud and on-premises security, outsourced SOC, crisis management, and DevSecOps automation.
Our recent projects include certified HDS cloud migrations, strengthening security for critical systems, deploying outsourced SOC for mid-size enterprises subject to DORA, large-scale DevSecOps implementation, and fully automating risk management processes.
