About Sisuka
Independent judgment. Operational perspective.
Sisuka Oy is a founder-led Finnish cybersecurity consultancy helping organizations make better security decisions and build lasting resilience.
The perspective
Cybersecurity viewed as part of the operating environment.
Security decisions do not exist in isolation. They affect availability, change, performance, people and the organization’s ability to recover. Sisuka’s perspective has been shaped by responsibility for complex, business-critical environments where those trade-offs are real.
We connect infrastructure, identity, networks, endpoints, cloud and recovery into one practical view. That broader perspective helps clients move beyond product-led fixes and invest in improvements that remain effective in day-to-day operations.
How we work
Clear enough to act on.
End-to-end thinking
We connect risk across platforms instead of treating network, endpoint, cloud and backup as separate worlds.
