Chunk Works

The accelerator for the Atos Genesis plan

A strategic deep-dive into how Chunk Works functions as a capability layer for structural cyber resilience, sovereign control, crypto-agility and higher margins within the new Atos.

Cyber Resilience Sovereignty & Control Crypto-Agility Mission-Critical

The Genesis course correction

The Genesis plan demands a shift from fragmented IT projects to long-term, value-driven partnerships. The focus is on cyber resilience, AI readiness and mission-critical stability. Chunk Works is not a product alongside the portfolio, but a capability layer that accelerates Atos delivery and increases differentiation.

Go-to-market clarity (important for internal alignment): primarily Atos (services-led) for implementation/managed services; optional productisation via Eviden can follow later, once there is proven attach rate and repeatable delivery.

Positioning in the architecture

What this means in one sentence

Atos sells and manages the service delivery; Chunk Works provides the architecture layer that reduces blast radius, enforces control and enables crypto-agility — without platform replacement.

Genesis-proof criteria

Comparison between traditional systems integration and a capability-layer approach.

Note: the scores are indicative and intended to structure the conversation. During the pilot, these metrics will be validated per client case.

Why it fits

  • 🚀
    Speed & time-to-value Modular integration: demonstrable value in weeks, not months.
  • 💰
    Margin potential Increases lifecycle value and attach rate without delivery overstretch.
  • 🧭
    Sovereignty & control Control is architecture: policies, keys and exit strategy can be demonstrably organised.
  • 👔
    C-level relevant CISO (security), CIO (continuity), CFO (predictability) — one coherent story.

Bridge to AI readiness (without the hype)

Genesis is AI-driven. Chunk Works supports this indirectly: it makes datasets more available and governance more auditable, so AI initiatives face less risk of downtime, lock-in or compliance blockers.

Use case 1

Ransomware: blast-radius reduction

In traditional architectures, a single incident often leads to widespread downtime. Chunk Works is designed to contain the impact and make recovery paths predictable.

Scenario label: the chart uses example values (illustrative). During a pilot, RTO/RPO targets are defined and measured per workload.

Commercial value for Atos

Premium "managed resilience" offering: assessment → implementation → monitoring/operations. Less incident-driven ad-hoc work, more repeatable service delivery.

Future-proof

Post-quantum security & crypto-agility

The structural problem: encryption is often static (tooling/architecture). Crypto-agility makes algorithms and key profiling replaceable without a "big bang" migration.

What Atos clients are missing today

  • • No controlled route to switch algorithms without risk.
  • • Key rotation and policy changes often require redesign or migration.
  • • "Harvest now, decrypt later" is especially relevant for long-retained data.
What this delivers: a manageable roadmap instead of a crisis project.
Scenario label: risk curves are illustrative to visualise the difference between "static" and "agile". During the pilot: define crypto profiles, rotation policies and evidence (audit artefacts).

Crypto-agility as a sellable use case

For whom
Government, healthcare, industry, finance: data with long retention periods.
What you sell
Crypto-agility assessment + policy & rotation plan + manageable migration path.
Why Atos wins
C-level topic, repeatable delivery, and a clear managed services extension.

Sovereignty: the control plane question

In practice, "sovereignty" is not just about location, but about who controls the levers: policies, key lifecycle, auditing and exit. This is often where multi-cloud strategies stall (too many control planes).

What the client wants (measurable)

  • • Demonstrable control over key and policy lifecycle.
  • • Audit artefacts that can be produced repeatably.
  • • Exit: no dependency on a single cloud/location/control plane.
  • • Limited blast radius during incidents.

What Atos can do with this

  • • "Sovereignty-by-design" delivery playbook (assessment → implementation → management).
  • • Governance & assurance: evidence as managed output.
  • • Clear role separation: client-controlled vs Atos-operated components.
  • • One consistent narrative towards CISO/CIO/Legal.

Key positioning

Not "more clouds" as the answer, but less dependency by architecturally embedding control and exit strategy.

Proposal: Genesis pilot (90 days)

Making it measurable (essential): the pilot is not about "nice slides", but about demonstrable KPIs and repeatable delivery.
KPI 1
Time-to-first protection
Days until first dataset/workload under the capability layer.
KPI 2
RTO/RPO (per workload)
Measured recovery targets, validated in scenarios.
KPI 3
Operational overhead
Hours/week for management (target: predictable and low).
KPI 4
Audit artefacts output
Evidence: policies, key rotation, logging/assurance.
30

Selection & scope

Day 1–30: select 2 accounts, determine workloads, define KPIs and evidence.

60

Implementation

Day 31–60: implementation + test scenarios (ransomware/outage or crypto-agility).

90

Board readout

Day 61–90: evaluate impact on margin, scalability, GTM and investment decision.

"Chunk Works is not an additional product, but the capability layer for structural cyber resilience, sovereign control and profitable growth."
