Your IT is up and running. But do you know what happens if it stops working?
All it takes is one compromised account, and SAP, Microsoft 365, Teams, or your approval processes all come to a standstill at once. Not because individual systems are insecure, but because no one understands the interdependencies between them.
Modern companies work with hundreds of applications, identities, interfaces, and external service providers. Many of these connections remain invisible until something goes wrong.
Digital Resilience Engineering identifies digital vulnerabilities before they turn into business risks.
One click. And suddenly, more things come to a standstill than you'd expect.
Minute 0
The News
A tampered message in Teams, from a familiar sender. One click.
Minute 5
Identity
Access has been compromised. It wasn’t the system that was attacked, but the person in front of it.
Lesson 1
The Chain
Microsoft 365 will be locked out. This will also prevent users from signing in to all connected systems.
Day 2
The Standstill
Approvals aren’t going through, invoices are piling up, and the sales department can’t access any data.
The failure is rarely the problem. It’s the lack of order.
Understanding Dependencies
What you see is just the tip of the iceberg. What you don't see is what determines your resilience.
Business processes, ERP systems, applications, and AI initiatives are just the tip of the iceberg.
A company’s true resilience is determined by the underlying digital dependencies.
What we see is just the tip of the iceberg. What lies beneath determines your company’s resilience.
Why Digital Resilience Engineering?
Digital resilience begins where visibility ends
Many companies invest in stable applications and available cloud services. But availability alone does not equal resilience. What matters is whether critical dependencies are understood, digital fragility is measurable, and business processes, identities, and SaaS platforms can actually be restored in the event of an emergency.
Just because everything is running smoothly doesn't mean you're resilient.
Cyber risk is not a new issue for most companies. However, it is much more difficult to identify one’s own digital vulnerabilities: hidden dependencies, recovery gaps, and critical connections between people, processes, and technologies.
The Framework
ARC | Architecture. Resilience. Control.
ARC organizes Digital Resilience Engineering into three distinct areas of focus: identifying dependencies, enabling recovery, and regaining control.
01 · Architecture
You can only protect what you see.
ARC makes critical dependencies between applications, data, identities, and technologies visible.
02 · Resilience
Resilience only becomes apparent in a crisis.
ARC helps you understand digital fragility and demonstrably strengthen your ability to recover.
03 · Control
Complexity requires control.
ARC provides transparency, accountability, and governance for a resilient digital future.
Measurability
Digital resilience cannot be assumed.
It must be measurable.
Digital Resilience Engineering makes fragility measurable. ARC assesses digital fragility across seven dimensions, thereby creating a robust foundation for prioritization and improvement. The Digital Fragility Score helps companies identify vulnerabilities, prioritize investments, and improve resilience specifically where it is most critical to business operations.
Solution Components
Two Pillars: Creating Transparency
and Ensuring Recovery.
SAP LeanIX — Enterprise Architecture Intelligence
Gain visibility into your
digital landscape .
Every resilience strategy begins with transparency regarding dependencies. SAP LeanIX provides visibility into business capabilities, applications, technologies, data flows, interfaces, and dependencies. ARC extends this foundation with Digital Fragility Analysis, revealing architectural risks, hidden dependencies, and resilience gaps before they turn into business risks.
Keepit | SaaS Resilience
Resilience means that data remains available and can be reliably restored.
The more core business processes run on Microsoft 365, Entra ID, and other SaaS services, the greater the dependence on these platforms.
Keepit protects a growing number of SaaS platforms with an independent cloud infrastructure: immutable backups, unlimited data storage at no additional cost, fully customizable retention policies, and granular, instant recovery. You decide where your data is stored—for example, in the EU.
True resilience is not evident during normal operations, but rather in times of crisis.

Why all4cloud Core?
A Look at Cloud ERP. Understanding the Digital Landscape as a Whole.
all4cloud Core understands the central role that cloud ERP plays in modern businesses. At the same time, digital resilience does not end with the ERP system. It arises from the interplay of identities, integrations, SaaS platforms, data flows, architecture, and recovery capabilities. Digital Resilience Engineering therefore broadens the perspective from a stable core system to the interdependencies that actually underpin day-to-day business operations.

Your Next Step
Every organization has an iceberg.
Applications, users, and business processes are visible. Dependencies, identities, recovery capabilities, and hidden risks, however, often are not. The question is not whether these dependencies exist. The question is whether you can understand, manage, and recover from them if they fail.
ARC | Architecture. Resilience. Control.
Make dependencies visible. Build resilience. Take back control.
Frequently Asked Questions About Digital Resilience Engineering
Digital Resilience Engineering reveals the digital dependencies that underpin business operations. It combines transparency regarding architecture and dependencies with measurable digital fragility, robust recoverability, and governance and control.
ARC stands for Architecture. Resilience. Control. Architecture provides transparency regarding dependencies. Resilience turns recoverability into a robust capability. Control establishes governance, ownership, standards, and continuous improvement.
Digital fragility describes how vulnerable an organization is due to hidden dependencies, a lack of transparency, limited recoverability, reliance on specific individuals, drift, unclear cost control, and high complexity.
ARC assesses digital fragility across seven dimensions: transparency, control level, recoverability, people dependency, drift, cost control, and complexity. This results in a Digital Fragility Score, which serves as a measurable baseline for prioritization and improvement.
Availability does not automatically mean recoverability. True resilience is demonstrated by whether critical dependencies are understood and whether business-critical systems, identities, and SaaS platforms can actually be restored in the event of an outage.
SAP LeanIX provides transparency into business capabilities, applications, technologies, data flows, interfaces, and dependencies. ARC complements this transparency with Digital Fragility Analysis and highlights architectural risks and resilience gaps.
Keepit supports the independent recoverability of business-critical SaaS platforms such as Microsoft 365 and Entra ID. Key components include Immutable Backup Architecture, independent cloud infrastructure, Unlimited Retention, and fast recovery.
The ARC Discovery Workshop raises management awareness, provides an initial fragility assessment, and prioritizes the next steps. For a more in-depth evaluation, a structured Digital Fragility Assessment can then be conducted.
