Cyber insurance professionals operate in fragments. Threat intelligence lives in one dashboard. Compliance posture in a spreadsheet. Breach cost estimates in an actuarial model. And coverage gaps? Those surface during claims, when it’s already too late.

There’s no unified framework that connects external threat data to insurance outcomes — nothing that lets an underwriter, broker, or risk manager trace a line from “there’s a ransomware campaign targeting VPNs in my sector” to “this is how it impacts my coverage and what I should do about it.”

The Resilience Stack™ changes that.

It’s a five-layer model that maps the complete journey from external threat landscape through insurance readiness. Each layer maps to a set of free assessment tools, so the framework isn’t theoretical — it’s operational from day one.

Why a Framework Matters

The cyber insurance market struggles with three structural problems:

Fragmented tooling. Threat intel platforms, compliance checkers, risk calculators, and submission tools are built by different vendors for different audiences. An underwriter using Bitsight has no natural path to a breach cost estimate. A broker running an NIS2 compliance check has no bridge to a coverage gap analysis.

Translation gaps. Each discipline speaks its own language. Threat analysts talk about CVEs and MITRE ATT&CK techniques. Compliance officers reference Article 21 measures. Risk quantifiers produce loss exceedance curves. Brokers discuss premiums and retentions. The Resilience Stack provides a shared vocabulary — Layer 2 findings feed Layer 3, which feeds Layer 4, which feeds Layer 5.

No end-to-end visibility. According to the 2025 IBM Cost of a Data Breach Report, organizations with security AI and automation saved an average of $2.22 million per breach compared to those without. But those savings only materialize when organizations can connect threat signals to financial outcomes to insurance decisions. Most can’t.

The Resilience Stack™ gives every stakeholder — from CISO to broker to underwriter — a single conceptual architecture for understanding cyber risk end to end.

The Five Layers

Layer 1: External Threat Landscape

Question: What’s happening in the wild that could affect this organization?

The first layer captures the adversary’s perspective — active campaigns, emerging CVEs, sector-specific threat intelligence, and macro risk trends. This is context-setting. Before you can assess an organization’s exposure, you need to understand what threats are targeting organizations like it.

In 2025, 85% of ransomware incidents in H2 exploited VPNs as the initial access vector (Corvus Q4 Threat Report). Ransomware-as-a-service platforms like Qilin consolidated 22% market share. Business email compromise drove 58% of insurance claims (Amwins). These aren’t abstract statistics — they’re the threat landscape that every Layer 2-5 analysis must account for.

Powered by:

• Threat Intelligence Feed — Live OpenCTI-powered threat data with NIST CVE, CISA KEV, and MITRE ATT&CK enrichment
• Weekly Threat Digest — Curated weekly intelligence briefing on active campaigns, threat actors, and vulnerability trends
• Industry Risk Landscape — Sector-specific threat profiling showing which adversaries target which industries
• Security Trends — Longitudinal data on vulnerability disclosure rates, ransomware payment trends, and attack vector evolution

What Layer 1 tells you: The threat environment is dynamic. A quarterly assessment isn’t enough. Continuous monitoring through real-time feeds and weekly digests ensures that Layers 2-5 always operate on current intelligence rather than stale data.

Layer 2: Exposure Surface

Question: How visible and vulnerable is this organization to the threats identified in Layer 1?

Threat intelligence without context is noise. Layer 2 translates “there are ransomware campaigns exploiting VPNs” into “this specific organization has 14 internet-facing services, 3 of which run unpatched software with known CVEs.”

Exposure isn’t limited to the organization’s own perimeter. Supply chain dependencies create inherited risk — a vendor’s breach becomes your incident. IoT devices expand the attack surface in ways traditional perimeter monitoring misses. And domain misconfigurations (dangling DNS records, exposed admin panels, unencrypted subdomains) create low-friction entry points that require zero-day sophistication to exploit.

Powered by:

• Domain Exposure Scanner — Identifies internet-facing assets, dangling services, misconfigured DNS, and open ports with financial exposure estimates in euros
• IoT Attack Surface Analyzer — Maps connected device risk, default credential exposure, and firmware vulnerability across IoT fleets
• Supply Chain Mapper — Evaluates third-party vendor risk, inherited exposure from suppliers, and concentration risk in critical dependencies

What Layer 2 tells you: The organization’s actual attackable surface. Layer 1 says “ransomware is exploiting VPNs.” Layer 2 says “this organization runs FortiOS 7.2 with CVE-2024-21776 unpatched on their VPN gateway, and their primary cloud vendor has a known exposure.” The difference between abstract risk and specific risk is where decisions get made.

Layer 3: Regulatory Posture

Question: Does this organization meet the compliance requirements that govern its cybersecurity obligations?

Regulatory non-compliance isn’t just a legal risk — it’s an insurance risk. NIS2 mandates specific technical measures (Article 21) with penalties up to €10 million or 2% of global revenue. DORA requires ICT risk management frameworks for all financial entities in the EU. Organizations that fail compliance checks face higher premiums, coverage exclusions, and claim denials.

The 2026 regulatory landscape has made compliance posture a first-class underwriting variable. Underwriters now routinely ask: “Does the insured meet NIS2 Article 21 requirements?” and “Has the financial entity established DORA-compliant ICT risk management?” The answers directly affect pricing, terms, and insurability.

Powered by:

• NIS2 Compliance Checker — Assess NIS2 Article 21 compliance across all 20 EU member state implementations with country-specific guidance
• DORA ICT Risk Checklist — Evaluate Digital Operational Resilience Act compliance across all five DORA pillars
• Compliance Timeline — Track regulatory deadlines, enforcement dates, and grace periods for NIS2, DORA, and emerging frameworks
• NIS2 Country Assessments — Country-specific compliance guides covering national transposition, enforcement authorities, and sector-specific requirements

What Layer 3 tells you: Whether the organization’s cybersecurity program meets the legal minimum. Layer 2 identifies technical vulnerabilities. Layer 3 determines whether those vulnerabilities also represent compliance failures — and compliance failures carry financial penalties that compound breach costs.

Layer 4: Financial Impact

Question: What’s the quantified financial risk in euros?

This is where cyber risk stops being a security exercise and becomes a business decision. Layer 4 translates Layers 1-3 into the language of CFOs, boards, and insurance actuaries: financial loss estimates.

The FAIR (Factor Analysis of Information Risk) methodology provides the analytical backbone: decompose risk into Loss Event Frequency × Loss Magnitude, apply Monte Carlo simulation to produce probability distributions, and output loss exceedance curves that show P50, P75, and P95 financial scenarios.

According to IBM’s 2025 Cost of a Data Breach Report, the global average breach cost reached $4.88 million — but regional and sectoral variation is enormous. Healthcare breaches average $9.77 million. German organizations face costs 42% above global averages. Layer 4 accounts for these differences with industry and region-specific parameters.

• Loss Exceedance Curve — Visualize tail risk with P50/P75/P95 loss thresholds for insurance program sizing
• Accumulation Visualizer — Identify correlated risk concentrations across portfolio that could trigger aggregate losses

What Layer 4 tells you: The financial exposure in hard numbers. Layer 1 says “threat actors are active.” Layer 2 says “you’re exposed.” Layer 3 says “you’re not compliant.” Layer 4 says “this specific configuration of risk translates to a P50 loss of €420K with a 5% chance of exceeding €2.1M.” That’s the number that goes on a balance sheet.

Layer 5: Insurance Readiness

Question: How does quantified risk translate to coverage, and where are the gaps?

The final layer bridges risk assessment and insurance decisions. It answers the questions that keep brokers up at night: “Can this client get placed?” “Are there coverage gaps the underwriter will carve out?” “What’s the right retention level?”

Insurance readiness isn’t binary. An organization can be compliant (Layer 3), have manageable financial exposure (Layer 4), and still fail to present a compelling submission to underwriters. The Layer 5 tools help organizations and their brokers translate the Resilience Stack’s findings into insurance-actionable outputs.

Powered by:

• Pre-Qualification Assessment — Determine insurability before approaching markets. Identifies red flags that trigger declinations or coverage restrictions
• Coverage Gap Analyzer — Map existing coverage against identified risks to surface gaps, exclusions, and underinsurance
• Broker Scorecard — Generate underwriter-ready risk summaries with financial exposure estimates, compliance posture, and binding recommendations
• Insurance Capacity Recommender — Match risk profiles to appropriate markets, capacity providers, and structure recommendations
• Pre-Submission Checker — Validate submissions before they reach underwriters, catching common errors that delay or derail placement
• Submission Packet Generator — Compile Layer 1-4 findings into a broker-ready submission document

What Layer 5 tells you: Whether the organization can actually get insured, at what price, and with what exclusions. Layer 4 identified a €420K P50 loss. Layer 5 determines whether that loss is coverable, what the premium should be, and which markets will write it.

How the Layers Connect

The Resilience Stack is designed to flow top-to-bottom. Each layer’s output feeds the next:

Layer 1: Threat Landscape
    ↓ "Here's what's attacking organizations like yours"
Layer 2: Exposure Surface
    ↓ "Here's where your organization is specifically vulnerable"
Layer 3: Regulatory Posture
    ↓ "Here's whether your defenses meet legal requirements"
Layer 4: Financial Impact
    ↓ "Here's what those gaps cost in euros"
Layer 5: Insurance Readiness
    → "Here's how that translates to coverage, and here's your submission"

A ransomware campaign targeting VPNs (Layer 1) surfaces an unpatched VPN gateway (Layer 2) that violates NIS2 Article 21 requirements for vulnerability management (Layer 3) creating a P95 financial exposure of €1.8M (Layer 4) that requires a specific cyber policy with ransomware coverage and incident response retainer in place (Layer 5).

Each layer narrows the aperture — from the vast threat landscape to the specific coverage recommendation.

The Tool Advantage

Every layer of The Resilience Stack maps to free, accessible assessment tools. This isn’t a theoretical framework requiring enterprise consulting engagements. An insurance broker can:

1. Run a domain exposure scan (Layer 2, 60 seconds) to identify a client’s internet-facing vulnerabilities
2. Complete an NIS2 compliance check (Layer 3, 5 minutes) to assess regulatory posture
3. Generate a breach cost estimate (Layer 4, 2 minutes) to quantify financial exposure
4. Produce a broker scorecard (Layer 5, 3 minutes) for underwriter submission

Total time: under 15 minutes. Total cost: €0 for the free tier, €29/month for unlimited access and PDF exports.

Compare that to the traditional approach: commission a SecurityScorecard assessment ($16,500/year), hire a consultant for NIS2 compliance review (€5,000–15,000), engage a CRQ firm for FAIR analysis (€50,000+/year), and then manually compile submission documents. The Resilience Stack compresses weeks of work and thousands of euros into minutes.

Who Is This For?

Insurance brokers use The Resilience Stack to produce higher-quality submissions faster. Instead of sending underwriters a blank application form, they send a Layer 5 scorecard backed by quantitative analysis from Layers 1-4.

Underwriters use it to validate submissions and identify red flags. A Layer 2 exposure scan reveals risks that applicants might not disclose. Layer 3 compliance checks surface regulatory gaps that affect pricing.

CISOs and risk managers use it to translate technical risk into board-ready financial language. The output of Layer 4 — a probability distribution of financial loss — is what CFOs and boards need to make investment decisions.

Compliance officers use Layers 1 and 3 to demonstrate due diligence. Continuous threat monitoring (Layer 1) and compliance tracking (Layer 3) create an audit trail that’s valuable both for regulators and for insurance renewal negotiations.

Building on the Stack

The Resilience Stack™ is Resiliently’s organizing principle. Going forward, every tool, blog post, and resource on this platform will reference which layer it addresses. This creates three benefits:

Coherent content architecture. Instead of a random collection of tools and articles, each resource has a clear home within the framework. A post about NIS2 enforcement belongs to Layer 3. A breach cost analysis sits in Layer 4. The weekly threat digest feeds Layer 1.

Progressive assessment. Users can enter the stack at any layer and work up or down. A broker might start at Layer 5 (pre-qualification) and discover they need Layer 2 data (exposure scan) to strengthen the submission. A CISO might start at Layer 1 (threat intelligence) and work through to Layer 4 (financial impact) for board reporting.

Measurable risk reduction. Each layer produces quantifiable outputs. Track your Layer 2 exposure score over time. Measure Layer 3 compliance percentage. Monitor Layer 4 P50 loss estimates. The Resilience Stack makes cyber risk progress trackable — not just for security teams, but for the insurance professionals who price and cover that risk.
