Service / PQC & Quantum Migration

Secure Communications Migration

Modernize encrypted communications across VPN, TLS, SSH, messaging and machine-to-machine channels with crypto-agile transition controls.

Business context

What this capability solves

Communication protocols are widely distributed and depend on endpoints, gateways, middleboxes and vendor support. A staged migration minimizes outages while reducing long-lived confidentiality risk.

EBP Integra delivery principle

Technology is implemented as an operating capability: architecture, integration, governance, assurance, people, procedures and measurable outcomes are designed together.

Deep-dive capabilities

Capability model

Modular building blocks allow the scope to start with a focused pilot and expand into an enterprise operating model.

Channel Inventory

Identify VPN, TLS, SSH, messaging, API and machine channels.

Protocol Profiles

Define approved cipher/key-exchange/signature profiles by environment.

Hybrid Pilot

Validate endpoints, gateways, proxies and performance.

Key Rotation

Rekey long-lived secrets and coordinate certificate updates.

Downgrade Detection

Monitor legacy fallback and unauthorized profiles.

Retirement

Remove classical-only modes according to priority and support readiness.

Reference architecture

How the capability fits together

Final topology, control placement and deployment model are validated during discovery and detailed design.

Inventory & Evidence

Assets, algorithms, protocols, keys, certificates, libraries, firmware, owners and dependency graph.

Risk & Governance

Data lifetime, HNDL/TNFL exposure, criticality, migration difficulty, target profiles and exception authority.

Migration Engineering

Hybrid algorithms, PKI/HSM/KMS, protocols, applications, devices, interoperability and test environments.

Continuous Crypto-Agility

Rescans, posture dashboard, key rotation, retirement, vendor tracking, evidence and assurance.

Implementation

Phased delivery

Each phase ends with evidence, acceptance criteria and a decision gate before broader scale-out.

1. DiscoverEstablish authoritative crypto inventory and ownership.

2. PrioritizeRisk-rank exposure using data lifetime, criticality and migration effort.

3. PilotValidate target/hybrid profiles and interoperability in controlled environments.

4. MigrateExecute waves, rekey, retire legacy, rescan and maintain evidence.
