Quantum security. Made simple.
For Quantum Security,
we get it done.
Period.
DONE. Quantum computers could one day break the encryption that protects banking, payments and personal data. Data stolen today can be unlocked later, so financial institutions need to start preparing now.
DONE. helps regulated organisations find where they rely on vulnerable encryption and plan the move to quantum-safe security. We start with a fixed-fee Quantum Readiness Assessment: a map of your exposure, the systems that matter most, and a board-ready plan for what to do first.
DONE. is a UK and US based company founded by Calia Brencsons-Van Dyk (CEO), Joel Van Dyk (CTO) and Jennifer Allerot (COO), with decades of experience across cybersecurity, financial services and company building.

DONE. helps organisations prepare for post-quantum security with practical tools, clear guidance, and a simpler way to begin.
Why DONE.
Why NOW
A market that must move
Quantum computers could one day break the encryption that protects financial data. Standards for quantum-safe encryption are now published. Data stolen today can be unlocked later, so waiting has a cost.
A Clear Place to Start
The Quantum Readiness Assessment is a fixed-fee review of where your organisation relies on vulnerable encryption. You receive a risk-ranked, board-ready plan for what to fix first, without replacing your existing systems.
Built by people who have done this work
Jennifer Allerot, Calia Brencsons-Van Dyk, and Joel Van Dyk bring decades across cybersecurity, financial services and company building.
What comes next
We are also developing the DONE. Platform, designed to help protect sensitive data flows alongside existing systems without rewriting applications.
Quantum readiness starts with knowing where encryption is used and what needs attention. Our fixed-fee Quantum Readiness Assessment maps that exposure and gives organisations a board-ready plan. We’re developing the DONE. Platform to help protect sensitive data flows alongside existing systems as organisations put their plans into practice.
