Post-quantum readiness, planned not rushed
Attackers can steal encrypted data today and decrypt it once a large enough quantum computer exists: "harvest now, decrypt later". Investgao Cyber helps you find where quantum-vulnerable cryptography lives, decide what to fix first, and move to NIST's post-quantum standards without disrupting the business.

From inventory to board-ready roadmap
Engagements are scoped to where you are today. Most organisations start with visibility, then prioritise and plan.
Cryptographic inventory
Find where RSA, ECC and Diffie-Hellman live: TLS, VPNs, code signing, PKI, backups and vendor products. Build a cryptographic bill of materials (CBOM) you can keep current.
Quantum risk assessment
Rank systems by how long their data must stay secret and how hard they are to change. Long-lived secrets and slow-to-replace systems go first.
Hybrid, crypto-agile roadmap
Plan adoption of ML-KEM and ML-DSA, often in hybrid mode alongside classical algorithms, and design systems so algorithms can be swapped without re-architecture.
PQC-aware incident response
Update IR playbooks: treat exfiltrated encrypted data as a future exposure, rotate keys with quantum-safe replacements, and log cryptographic posture.
Quantum-safe evidence
SHA-256 evidence hashes remain sound. Signatures on long-lived reports and evidence packages should plan a move to post-quantum signatures.
Vendor requirements & board reporting
Turn the timelines into budget, procurement requirements and milestones leadership can track, before regulators and customers ask.
The quantum clock is already running
Migration is a multi-year programme, not a patch. The standards are published and the deprecation dates are set.
Built for the people who own the risk
CISOs & security teams
A practical migration roadmap: cryptographic inventory, risk ranking and the questions to put to vendors.
Architects & engineering
Where hybrid key exchange fits, how to build crypto-agility in, and what to test before rollout.
Boards, risk & compliance
Plain-language briefings on exposure, timelines and emerging quantum-readiness obligations.
