In March 2026, the CyberStrikeAI campaign used fully autonomous AI engines to breach over 600 FortiGate firewalls across 55 countries.

Let that sink in. 600 firewalls, 55 countries. This is the age of AI. The attack speed is impossible to match with human defenders.

The only defense against AI-powered attacks is to eliminate the path to a critical digital system using Zero Trust. And organizations are defining digital systems as a Minimum Viable Enterprise (MVE) that must be recoverable in the event of cyberattacks.

However, in 2026, as attack methods change, so do the mechanisms for defense. Zero Trust is fueling an upgrade to the MVE concept.

Introducing the Minimum Viable Digital Enterprise

The term ‘Minimum Viable’ entered business vocabulary through Eric Ries’s Lean Startup methodology (2011), where the Minimum Viable Product (MVP) described the smallest version of a product sufficient to test core hypotheses with real customers. The concept was borrowed and extended across disciplines, and by the mid-2020s, it had arrived in cybersecurity and digital resilience in a powerful new form.

The traditional concept of a Minimum Viable Enterprise (MVE), originally based on “Minimum Viable Company (MVC)” frameworks used by firms like KPMG and PwC, is grounded in Business Continuity. The critical distinction between traditional Business Continuity Planning (BCP), Disaster Recovery (DR), and the MVE is the assumed failure mode and the required response time. Business Continuity is about ensuring that certain parts of a business continue operating after a cyberattack.

This means that enterprises would plan to keep only 15–20% of their total business operational as the MVE.

That is not practical. Because, in the end, the attackers succeed in creating a disruption. That is what they want.

We need to change the script. We must let the defenders gain an edge. To begin, we need to understand where we are headed with current MVE planning.

Decomposing MVE into Engineering Constructs

As it stands today, the MVE is not a list — it is a dependency graph. The core components include:

Business Capabilities

• Revenue generation (payments, orders)
• Customer access (portals, APIs)

Digital Assets

• Applications (ERP, trading, EHR)
• Data stores (customer DB, transactions)

Provisioning Systems

• Identity (AD, IAM) → foundational
• Network access
• Security enforcement

Industrial Systems

• PLCs, SCADA, DCS
• Cyber-Physical devices
• MES, HMI, Data lakes
• Xray machines, digital beds, MRI machines

Operational Dependencies

• DNS, authentication, messaging, APIs
• Suppliers and vendors

The Current Industry Approach

• Conduct Business Impact Analysis (BIA)
• Map RTO / RPO
• Build Tiering systems (Tier 0, Tier 1, Tier 2)
• Conduct dependency mapping workshops

This poses a few challenges.

Challenge 1: Static Thinking. Unlike assumptions made in most business continuity workshops for non-digital scenarios, digital systems, especially OT systems, do not operate in only two states, available or unavailable. In reality, there are situations in which some systems are up, and others are down. And almost always, these create unforeseen vulnerabilities that most cyber attackers usually exploit. Like earthquakes, foiled cyberattacks have aftershocks. This is why modeling cyber defenses is absolutely critical during post-attack recovery.

Challenge 2: No Attack Path Modeling. Most business impact analyses are not based on measured breach exposure of digital systems due to unmonitored and unmanaged lateral movement, potential privilege escalations, and the blast radius on digital systems. In a rapidly evolving AI era, when the perimeter can no longer be trusted, every connection and every possible attack path must be verified in real time to deny attackers, in real time, whether they are human or autonomous agents.

Challenge 3: Overestimation of Required Assets. When considering traditional business continuity planning, organizations include the entire ERP rather than core functions, or entire network segments rather than minimal flows, primarily because the focus is not on the material impact of the breach but on operational unavailability. The difference lies in the allocation of resources to ensure digital systems remain unaffected, within acceptable levels of material impact on the business and its stakeholders.

Challenge 4: Recovery-Centric focus. Most BIAs are conducted by IT teams from an infrastructure perspective. They identify systems and applications, not business outcomes. The result: a prioritized list of servers, not a model of the minimum digital value chain. The hospital IT team can tell you the EHR server’s RTO. They cannot tell you which clinical workflows survive if only 40% of the IT estate is operational.

We need to change the focus from recovery to remaining “unaffected and operational” during a breach.

This is the time to use zero-trust mechanisms to plan for creating unaffected digital enterprises. If business leaders are asking, “What must we recover first?”

That already assumes an apocalyptic breach, where media statements read “we have shut down all our operations to protect stakeholder interests and we shall resume once our cyber experts advise us. That is a defeatist post-breach mindset, which cannot resume parts of the business because it was not designed to do so.

But there is hope. ColorTokens is spearheading capabilities to build breach-ready digital enterprises that can remain “unaffected” during a cyberattack.

We can now limit cyberattacks to their point of origin, ensuring digital immunity for systems outside the blast radius.

The Egregious Role of Lateral Movement and The Value of Breach-ready Microsegmentation

Research consistently shows that up to 70% of breaches involve lateral movement. This means that even if your MVE is correct, it will collapse if the attack spreads across dependencies after an initial compromise. And in 2026, it is common knowledge that attacks will happen, and attackers will find ways to bypass initial defenses.

Organizations define a Tier 0 asset list, but flat networks mean lateral movement can reach any Tier 0 asset from any compromised Tier 3 asset. A workstation in a non-critical HR system serves as the entry point to the payment-processing core. The MVE definition is correct on paper, but irrelevant in practice.

Traditional MVE thinking is entirely recovery-focused: isolate the breach, run forensics, restore from backup. Average recovery time from a ransomware attack: 24 days. The ‘minimum viable’ state requires businesses to shrink to near-zero for 24 days. Enterprises will first shut down operations and then attempt to recover 15–20% of the business. That is not minimum viable operations, that is minimum viable collapse.

Consider another reality. CrowdStrike’s 2026 Global Threat Report confirms that AI-assisted adversaries now compress breakout time to 29 minutes — with the fastest observed case at 27 seconds. Average MTTR in enterprise SOCs: hours.

The MVE in its current construct will have been traversed before a human analyst reads the first alert.

Transforming the MVE to MVDE

According to a MIT Sloan report, CEOs regretted focusing too narrowly on preventing cyberattacks. And they believed they were prepared before the attack. After the attack, that confidence dropped significantly.

That was before we operationalized zero trust by designing a progressive approach to reducing the attack surface and blast radius during cyberattacks, ensuring attacks remain contained within microsegments where they originate. These capabilities of modern zero-trust-driven cyber resilience demand new ways of conceptualizing the MVE.

The objective is no longer about recovery.

It is about operational survivability under active cyberattack.

The cultural shift moving from MVE to MVDE.

The ColorTokens Breach Ready Microsegmentation provisions Cyber Defense modeling, Progressive hardening, Reduction of Blast Radius, Least-privilege communication, Workload-level isolation, and Attack containment capabilities.

It reduces attack propagation by 60–90% based on graph-based evaluation models. This transforms the MVE approach to operate up to 85% of the business “unaffected,” with business-continuity-based recovery targeted at 15–20% of the affected areas.

This heralds new calculations for estimating MVE, which now includes the capability to contain and quarantine the attack within the microsegment where it occurred, enabling a digital enterprise to continue operating critical business functions even during unprecedented zero-day cyberattacks.

At the core lies the zero-trust architecture, as defined in NIST SP 800-207. Zero-trust architecture is a digital-only approach; therefore, it is prudent to call the modern approach the Minimum Viable Digital Enterprise or MVDE.

Because it is designed to keep cyberattacks limited to microperimeters, companies can now plan to keep 80–90% of their digital business operational even during unprecedented zero-day cyberattacks.

The MVDE, then, is the smallest set of business capabilities, processes, and digital assets required to remain “unaffected” during a disruption.

This redefines the role of business continuity management in a manner not foreseen until now. Enterprises now plan to implement business continuity for the part of the business that was “affected” by the cyberattack.

The Minimum Viable Digital Enterprise, or MVDE, sits at the intersection of resilience engineering, Zero Trust architecture, and business continuity economics, focusing on operational survivability under active cyberattacks.

Let’s build this rigorously with the serious diligence it needs.

Engineering the MVDE

To determine which digital assets belong in the Minimum Viable Digital Enterprise, it is essential to build a repeatable methodology that synthesizes NIST IR 8286D, ISO 22301, the KPMG MVC framework, FFIEC guidance, academic MADM research, and ColorTokens’ breach-readiness framework into a single, executable process.

Unlike traditional BIA approaches, it starts with business value (top-down) before mapping technology (bottom-up), deliberately avoiding the IT-centric trap that causes most MVE definitions to fail.

Here is a five-phase methodology to ensure that the MVE is designed for business benefit, optimizes leadership intent for innovation and profit, and remains reasonably unaffected by cyberattacks. This is the “be breach ready” approach to stay a step ahead of the attackers, human or AI.

• Define the Minimum Business Continuity Objective (MBCO) and the maximum Material Risk that is acceptable to the Board.
• Map the Digital Value Chain for Each Minimum Business Service (MBS)
• Score all the assets that ensure the Minimum Business Service remains unaffected to build the MVDE.
• Get an answer for, ‘Would the Board Tolerate This?’ Validate the MVDE and its value for stakeholders.
• Continuously Update Using Automated Asset Discovery tools.

Call to Action: Making the Paradigm Shift from ‘Recover a Few’ to ‘Being Reasonably Unaffected’

Traditional MVE thinking is driven by one question: how few assets can we protect so completely that they survive any breach? The answer defines a very small, expensive, and highly redundant core, typically 10–20% of the digital estate, and accepts that the remaining 80–90% may remain unavailable during a breach.

ColorTokens Xshield introduces a fundamentally different question: how many assets can we architect to stay unaffected by a breach? When microsegmentation enforces workload-level isolation, the answer changes dramatically. As ColorTokens documents, breach-ready organizations remain largely (upwards of 80%) unaffected, while business continuity is invoked for the affected parts.’

It is a mathematical consequence of microsegmentation architecture. If an attacker compromises one asset and Xshield has enforced allow-list policies that prevent that asset from communicating with any adjacent system except via explicitly authorized paths, the blast radius is, by definition, contained to that microsegment. The MVDE does not need to shrink to survive, it needs containment. Specifically engineered micro
