The breach has already started. You just can't read the data yet.

Adversaries are intercepting and storing your encrypted communications today, waiting for quantum computers to arrive before decrypting them. Google has set an internal deadline of 2029. Most organizations don't know they're already behind.

Walking into a board meeting on quantum risk without the right material is a liability.

Most boards haven't put it on the agenda. Most CISOs don't yet have a concise way to explain why it's urgent, or what approving action actually looks like.

The Quantum Threat

An Executive Briefing for Boards and Risk Committees

Prepared by Horizen Labs2026

This briefing was built to close that gap.

It explains the threat without technical overhead, anchors the timeline to current expert data and regulatory mandates, and gives the board five concrete actions they can approve in a single meeting.

It is a decision-support tool for the room where quantum risk either gets funded or ignored.

What's Inside:

The threat, in plain language

How RSA and ECC, the algorithms underpinning ~99% of public-key cryptography, get broken by a quantum computer, and what that means for data your organization encrypted years ago.

Harvest Now, Decrypt Later and Trust Now, Forge Later

The two threat vectors already in play: encrypted data being stockpiled for future decryption, and the coming collapse of digital signatures, certificates, and identity infrastructure.

The Q-Day timeline, sourced and current

Expert consensus from the Global Risk Institute, Google's own 2029 internal deadline, and Craig Gidney's landmark 2025 research, in one clear slide your board can absorb.

The regulatory wall

Eight jurisdictions. Binding mandates. First procurement deadlines in 2027. A map of who's requiring what, by when.

A maturity model your board can self-assess against

Four stages from Exposed to Migrated. Most organizations are at Stage 1: no cryptographic inventory, no board awareness, full RSA/ECC dependency.

Five board-level actions

Concrete, approvable, sequenced. Starting with the prerequisite every organization skips: you cannot migrate what you have not mapped.
