# Europe Cybersecurity Market: ASM Demand, Spending, and Buyer Priorities

## Executive Summary

- **Sustained Market Expansion**: IDC forecasts European security spending to grow **11.8% in 2025** and approach **$97B by 2028**, while security software accounts for more than half of spending and grows **14.8%** -> suppliers should emphasize software-led platforms, cloud security, and identity while maintaining services for implementation and operations ([12]).
- **Material Enterprise Budgets**: ENISA's latest investment study reports a **EUR1.5M median cybersecurity budget**, **EUR20M median IT budget**, and **9% median security share** for the 2024 reference year -> ASM vendors must compete for a defined security allocation rather than assume they create an entirely new budget ([101]).
- **Observable ASM Spending Range**: Published pricing ranges from **GBP1,068 a year for 10 assets** to Microsoft list-price arithmetic of **$401,500 a year for 100,000 assets**; a UK government Censys award was **GBP41,105.27 for one year and up to 2,500 assets** -> budget by billable asset count, coverage, integration, and service level, not by company headcount alone ([48], [49], [56]).
- **No Defensible European Average**: No authoritative source located publishes average ASM expenditure per European company, and market definitions vary between ASM, EASM, CAASM, and exposure management -> use the transparent scenarios in this report rather than a false single-number average.
- **ASM Outgrows Core Security**: Grand View Research's public summary estimates **31.2% European ASM CAGR from 2024 to 2030**, substantially faster than IDC's overall European security forecast -> ASM has strong expansion potential, but the figure is a commercial forecast rather than observed revenue ([27]).
- **Buyers Want Outcomes, Not Inventories**: The strongest requirements are continuous discovery, reliable asset ownership, exploitability and business context, validation, ticketing and SIEM integration, and closed-loop remediation -> vendors selling another vulnerability list will struggle against platforms that demonstrate exposure reduction ([5]).
- **Regulation Converts Visibility Into Evidence**: NIS2 covers **18 critical sectors**, DORA has applied since **17 January 2025**, and CRA reporting duties apply from **11 September 2026** -> regulated buyers need current asset, vulnerability, supplier, and incident evidence, although none of these rules mandates an ASM product by name ([45], [39], [36]).
- **Exposure and Runtime Monitoring Are Complementary**: EASM identifies what an attacker can see; CNAPP and vulnerability management assess known cloud and internal assets; SIEM and XDR detect activity; MDR supplies people and process; CTEM connects these into a recurring risk-reduction program -> buyers should integrate these layers instead of treating ASM as a SIEM, XDR, or MDR replacement.
- **Skills Make Managed Delivery Valuable**: ENISA reports that **76%** of surveyed organizations struggle to attract and **71%** struggle to retain cyber professionals; its MSS study also finds expertise shortages on both the buyer and supplier sides -> managed ASM and MDR can unlock demand, provided customers retain risk ownership ([101], [58]).
- **Execution Risk Is High**: False positives, incorrect asset attribution, duplicate tools, weak remediation ownership, data residency requirements, and SME underfunding can erase ASM's business case -> run a time-boxed proof of value measured by newly found assets, validated critical exposures, remediation time, and inventory accuracy rather than alert volume.

## A European Market Approaching $97B by 2028

The most directly comparable IDC forecast found projects **11.8% year-over-year European security-spending growth in 2025** and annual spending of nearly **$97B by 2028**. Security software represents more than half of European spending and is forecast to grow **14.8% in 2025**, with cloud-native application protection platforms and identity products among the cited drivers ([12]).

A separate commercial estimate values the European cybersecurity market at **$76.21B in 2025** and **$85.68B in 2026**. It should not be substituted into the IDC series because the publishers use different market boundaries and methods ([30]). This definition risk is material: Gartner forecasts worldwide end-user information-security spending of **$213B in 2025** and **$240B in 2026**, while IDC's broader global security forecast reaches **$308B in 2026** and **$430B in 2029** ([11], [109]).

| Metric | Published figure | Scope and decision value |
|---|---:|---|
| European security-spending growth | **11.8% in 2025** | IDC forecast; strongest directly comparable Europe growth signal |
| European annual security spending | **Nearly $97B by 2028** | IDC forecast endpoint, not a 2026 market value |
| Security software growth | **14.8% in 2025** | Faster than total European security spending |
| Commercial 2026 market estimate | **$85.68B** | Useful cross-check, but not directly comparable with IDC |
| Czech Republic, Hungary, Ireland growth | **15.4%, 14.1%, 13.3%** | Smaller high-growth country opportunities |
| Aerospace and defense, banking growth | **13.5% each** | Attractive regulated verticals |
| Capital-markets growth | **13.3%** | Supports DORA-linked opportunities |

IDC says very large businesses with at least 1,000 employees account for just under half of spending, but organizations with 10 to 499 employees are the fastest-growing size group. This creates two different go-to-market motions: enterprise platforms should target regulated, multi-cloud organizations, while SMEs require low deployment effort, transparent pricing, and managed operation ([12]).

**Decision-ready insight:** Europe is a durable double-digit-growth security market, but the best entry points are not uniform. Prioritize banking, capital markets, aerospace and defense, critical infrastructure, and fast-growing Central European countries for high-value deployments; use packaged and managed offers for SMEs.

## What European Organizations Spend, and What ASM Can Cost

ENISA's NIS Investments 2025 study collected **1,080 responses across all 27 EU Member States** and 22 high-criticality sectors. For the 2024 reference year, the overall sample reported a **EUR20M median IT budget**, **EUR1.5M median information-security budget**, and **9% median security share of IT spending**. The report separately gives a **7.1% average share**, so the median and average should not be confused ([101]).

The median security budget rose from **EUR1.4M in 2023 to EUR1.5M in 2024**, while median cybersecurity staffing increased from five to six FTEs. Cyber staff nevertheless declined to **10.6% of IT FTEs**, supporting greater technology and outsourcing expenditure rather than proportional internal-team growth. The sample is weighted toward large organizations, at 83% of respondents, so the EUR1.5M median is not an SME benchmark ([101]).

### Published ASM price benchmarks

| Observable benchmark | Annual arithmetic | What it does and does not show |
|---|---:|---|
| Attack Surface Center Starter, 10 assets | **GBP1,068** | GBP89 monthly list price; small-team entry point |
| Attack Surface Center Standard, 30 assets | **GBP2,148** | GBP179 monthly; adds risk register and reporting |
| Attack Surface Center Advanced, 100 assets | **GBP5,988** | GBP499 monthly; daily automation and integrations |
| Microsoft Defender EASM, 1,000 assets | **$4,015** | $0.011 per asset per day x 365; software list-price estimate |
| Microsoft Defender EASM, 10,000 assets | **$40,150** | Same unit-price arithmetic; actual agreements and exchange rates vary |
| Microsoft Defender EASM, 100,000 assets | **$401,500** | Demonstrates sensitivity to discovered billable-asset volume |
| UK Department for Education Censys award | **GBP41,105.27** | One year, up to 2,500 assets; reseller, service, and VAT treatment are not fully disclosed |

Sources: [48], [49], and [56].

### Case study: Censys at the UK Department for Education

The Department for Education awarded Bytes Technology Group a **GBP41,105.27** contract for Censys Enterprise Attack Surface Management. The agreement runs from **18 April 2026 to 17 April 2027** and covers up to **2,500 assets**. Dividing the award by maximum coverage produces **GBP16.44 per covered asset-year**, but that is procurement arithmetic, not a transferable list price because actual utilization, support, reseller margin, and VAT are unknown ([56]).

The case demonstrates that a large public organization can procure enterprise EASM in the tens of thousands of pounds annually rather than necessarily in the millions. It also shows why asset definitions matter: domains, IPs, hosts, certificates, and cloud resources can expand billable inventory much faster than employee count.

**Decision-ready insight:** A defensible planning range is low thousands annually for tightly bounded small deployments, tens of thousands for mid-sized external footprints, and potentially hundreds of thousands for very large asset estates. Add implementation, integration, validation, and managed-service costs separately. There is no credible evidence for one Europe-wide average ASM spend per company.

## Europe's ASM Demand Could Grow 31.2% Through 2030

Attack surface management continuously discovers, attributes, assesses, prioritizes, and monitors assets and exposures. External ASM focuses on internet-facing assets from an attacker's perspective. CAASM aggregates asset data from internal tools. Broader exposure-management and CTEM programs add business scoping, attack-path validation, remediation mobilization, and outcome measurement.

Grand View Research's public summary forecasts a **31.2% CAGR for European ASM from 2024 through 2030**. A separate FortifyData estimate places the global market at **$856.5M in 2024** and **$4.29B by 2032**, a **22.6% CAGR**. These estimates establish high expected growth but also expose major definition dispersion, so they should not be averaged or converted into an unsupported European revenue total ([27], [28]).

European demand has three concrete mechanisms. First, the asset base expands through cloud services, SaaS, APIs, remote work, acquisitions, and third parties. Second, ENISA finds vulnerability and patch management to be the most challenging NIS2 implementation area for **50%** of organizations, followed by business continuity at **49%** and supply-chain risk at **37%**. Third, **63% of SMEs** reported no cybersecurity assessment in the prior year, while **51% of SMEs** take more than three months to patch critical vulnerabilities ([101]).

A 2024 ESG survey provides directional demand evidence, although its respondents were in the United States and Canada rather than Europe. It found **62%** had experienced attack-surface growth, more than **75%** had suffered an attack exploiting an unknown, unmanaged, or poorly managed internet-facing asset, **48%** spent more than 80 person-hours on discovery, and **32%** consulted more than 11 data sources for asset information ([63]). These figures should explain the buying mechanism, not be presented as European adoption rates.

### What buyers want

1. **Continuous, seedless discovery:** Find unknown, unmanaged, abandoned, cloud, subsidiary, and third-party-connected assets without relying only on an existing CMDB.
2. **Accurate attribution and ownership:** Explain why an asset belongs to the organization and route it to the responsible team.
3. **Risk context:** Combine exploitability, active threats, internet reachability, business criticality, and attack paths instead of ranking only by CVSS.
4. **Validation:** Confirm whether a finding is exploitable and suppress duplicates and false positives.
5. **Closed-loop remediation:** Integrate with IT service management, vulnerability management, SIEM, SOAR, cloud, and developer workflows.
6. **Evidence and metrics:** Report newly discovered assets, critical exposures, mean time to ownership, mean time to remediation, recurrence, and exposure trend.
7. **Data sovereignty and service options:** Support European hosting, access controls, managed validation, and local response requirements.

These criteria align with the ESG buyer guide, which was commissioned by Palo Alto Networks and should therefore be treated as sponsored buyer guidance rather than independent market sizing ([5]).

**Decision-ready insight:** The strongest demand is for exposure reduction, not asset discovery alone. A winning ASM offer must establish ownership, validate risk, and trigger remediation inside existing operations.

## SIEM, XDR, MDR, CNAPP, and CTEM Converge Around Exposure

ASM does not replace runtime monitoring. It answers "what exists and is exposed?" while SIEM, XDR, and MDR answer "what is happening and how should we respond?" CNAPP protects cloud development and runtime environments; vulnerability management evaluates known assets; CTEM supplies the recurring management framework.

| Tool or model | Primary job | Demand driver | Main limitation if used alone |
|---|---|---|---|
| EASM or ASM | Discover and monitor exposed assets from outside | Unknown assets, cloud sprawl, acquisitions, supplier links | May stop at inventory and findings |
| CAASM | Reconcile internal asset records across tools | Conflicting CMDB, endpoint, identity, and cloud inventories | Depends on connector quality and source coverage |
| Vulnerability management | Scan known assets and prioritize weaknesses | Patch obligations and exploit activity | Misses unknown assets; can generate large backlogs |
| CNAPP | Protect cloud code, posture, entitlements, workloads, and runtime | Cloud-native development and multi-cloud expansion | Does not cover the full external or on-premise surface |
| SIEM and SOAR | Centralize telemetry, correlate events, automate response | Compliance evidence and cross-environment detection | Log cost, tuning, and alert overload |
| XDR | Correlate endpoint, identity, email, network, and cloud detections | Faster investigation and response | Best coverage may depend on one vendor ecosystem |
| MDR or MSS | Supply monitoring, expertise, hunting, and response | Skills shortages and 24x7 coverage | The customer must retain governance and risk ownership |
| CTEM | Scope, discover, prioritize, validate, and mobilize remediation continuously | Need to turn multiple tools into measurable exposure reduction | Operating model, not a single-product shortcut |

ENISA's June 2025 MSS analysis shows why managed monitoring demand will grow but also why it will not replace internal accountability. Most demand-side respondents allocated **less than 10% of their security budget** to MSS; **86% did not outsource risk management**, and **67% operated their own network infrastructure**. At the same time, expertise shortages affected **52% of demand-side** and **51% of supply-side** respondents, while integration challenges affected **38% of buyers** ([58]).

A second tension is supplier enthusiasm versus buyer demand. ENISA found cybersecurity-as-a-service offered by **73% of suppliers** but requested by only **19% of demand-side respondents**. Data-storage location was important to **76% of buyers** and **78% of suppliers**, and compliance was prioritized in procurement. The mechanism is clear: buyers want external capacity, but only under strong integration, sovereignty, and governance conditions ([58]).

**Decision-ready insight:** Build an integrated exposure-to-detection architecture. Feed ASM discoveries into vulnerability management, CNAPP, SIEM, and ticketing; use XDR and MDR for runtime verification and response; govern the portfolio through CTEM metrics.

## NIS2, DORA, CRA, and Current Threats Drive Demand

European cybersecurity demand is increasingly deadline- and evidence-driven. The regulations do not prescribe ASM, but they increase the value of reliable asset inventories, continuous risk assessment, supplier visibility, vulnerability handling, incident evidence, and management reporting.

| Regulation | Scope and timing | ASM and monitoring relevance |
|---|---|---|
| NIS2 | Unified framework across **18 critical sectors**; replaced NIS1 from 18 October 2024 | Risk management, incident handling, supply-chain security, vulnerability management, and management accountability |
| DORA | Applies to EU financial entities from **17 January 2025** | ICT risk management, resilience testing, incident reporting, and third-party ICT oversight |
| Cyber Resilience Act | Reporting obligations from **11 September 2026**; main obligations from **11 December 2027** | Product vulnerability handling, secure lifecycle evidence, and reporting for products with digital elements |

Sources: [45], [39], and [36].

ENISA's latest threat landscape analyzed **4,875 incidents from 1 July 2024 through 30 June 2025**. DDoS represented **76.7%** of recorded incidents and intrusions **17.8%**. Phishing was the initial access vector in **60%** of analyzed cases, followed by vulnerability exploitation at **21.3%** and botnets at **9.9%**. Hacktivists accounted for nearly 80% of incidents, while ransomware remained especially consequential by impact ([111]).

Public administration was the most targeted sector at **38%**, followed by transport at **7.5%**, digital infrastructure and services at **4.8%**, finance at **4.7%**, and manufacturing at **2.9%**. The high DDoS share supports external-service visibility and availability monitoring; the phishing share supports email, identity, XDR, and awareness controls; vulnerability exploitation supports EASM, vulnerability management, CNAPP, and rapid patch workflows. No one tool addresses all three mechanisms ([110]).

**Decision-ready insight:** Sell and buy ASM as one evidentiary layer in a broader control system. Regulated organizations should connect exposed-asset evidence to patching, incident response, third-party oversight, continuity testing, and executive reporting.

## Platforms Consolidate ASM While Specialists Retain Openings

The market contains global security platforms, dedicated exposure specialists, and European providers. The following is a representative capability map, not a market-share ranking.

| Vendor or group | Representative offer | Strategic position | Best-fit buyer |
|---|---|---|---|
| Microsoft | Defender External Attack Surface Management | Transparent per-asset pricing and Microsoft security integration | Microsoft-centered enterprises |
| Palo Alto Networks | Cortex Xpanse | EASM integrated with a broad SecOps and exposure platform | Large platform-consolidation buyers |
| CrowdStrike | Falcon Exposure Management and Reposify capabilities | External exposure tied to endpoint, identity, and cloud telemetry | Falcon customers |
| Tenable | Tenable Attack Surface Management and Tenable One | EASM linked to vulnerability and exposure management | Vulnerability-management-led programs |
| Rapid7 | Surface Command and Exposure Command | Asset visibility connected to VM and SecOps | Existing Rapid7 customers |
| IBM | Randori Recon | Attacker-perspective discovery and prioritization | Large hybrid enterprises and service-led buyers |
| Censys | Censys Attack Surface Management | Internet-scale discovery and external asset intelligence | Teams prioritizing external accuracy |
| CyCognito | External ASM and exposure management | Specialist discovery, context, and remediation workflows | Heterogeneous large enterprises |
| Outpost24 and Detectify | European EASM and application exposure offerings | Regional delivery and specialist focus | Buyers valuing European presence and web exposure depth |

Sources include [49], [84], and [6].

### Case study: Expanse made EASM a platform capability

Palo Alto Networks completed its acquisition of Expanse in December 2020 for total consideration of approximately **$800M**. The strategic logic was to combine outside-in asset discovery with Cortex detection and response rather than keep EASM as an isolated inventory tool ([114]).

IBM announced its Randori acquisition in June 2022 to add attacker-perspective ASM and offensive-security expertise, while CrowdStrike announced its Reposify acquisition in September 2022 to connect EASM with the Falcon platform. Tenable similarly moved to acquire Bit Discovery to add continuous external asset discovery to vulnerability management ([113], [102], Tenable Bit Discovery Announcement).

These cases reveal the competitive mechanism: ASM discovery is becoming a feature of broader exposure and SecOps platforms. Specialists can still win through superior attribution, faster discovery, validation, service, regional hosting, or application-specific depth, but a discovery-only product faces mounting bundling pressure.

**Decision-ready insight:** Platform vendors should sell integrated remediation and telemetry economics. Specialists should avoid feature parity battles and prove discovery accuracy, lower false-positive burden, faster ownership, European data handling, or underserved midmarket delivery.

## Skills, False Positives, and Tool Costs Can Break the Case

Strong forecasts do not guarantee successful deployments. ENISA reports that **76%** of organizations struggle to attract and **71%** struggle to retain cyber professionals. Its latest investment study also finds **63% of SMEs** conducted no cybersecurity assessment in the preceding year, showing that need does not automatically become funded demand ([101]).

ISC2's 2025 global study, which included respondents from multiple European countries, found **36%** of organizations experienced budget cuts, **39%** hiring freezes, and **24%** layoffs. It also found **47%** of professionals felt overwhelmed by workload. These are global results, not Europe-only rates, but they challenge the assumption that every security category receives budget simply because aggregate spending rises ([40]).

| Risk | How it destroys value | Mitigation and procurement test |
|---|---|---|
| False attribution | Teams investigate assets they do not own | Require evidence trails and measured attribution precision |
| False positives and duplicate findings | Analyst workload rises without reducing risk | Test deduplication and validated critical-exposure rate |
| Stale discovery | Inventory becomes another CMDB snapshot | Measure discovery and change-detection frequency |
| No remediation owner | Critical findings remain open | Require automatic owner mapping, ticketing, and escalation |
| Tool overlap | EASM, VM, CNAPP, SIEM, and XDR duplicate data and cost | Map each tool to a distinct decision and retire redundant functions |
| Billable-asset expansion | Per-asset economics rise unexpectedly | Run discovery before committing and negotiate asset bands |
| Data sovereignty | Hosting or support model blocks regulated procurement | Contract for storage location, subprocessors, access, and retention |
| Market-definition risk | A headline TAM leads to poor revenue planning | Model EASM, CAASM, CTEM, and services separately |

A useful proof of value should run against a defined business unit and compare vendor results with known inventory. Track new verified assets, critical exploitable exposures, ownership rate, false-positive rate, time to ticket, time to remediation, recurring exposure, connector effort, and fully loaded cost. Do not select a platform based on total findings, because a larger number can indicate worse prioritization rather than better security.

**Decision-ready insight:** ASM creates value only when findings become owned remediation. Buyers should gate expansion on verified coverage and remediation outcomes; vendors should price and scope deployments to avoid asset-count shock.

## Recommended Market and Procurement Strategy

For vendors, the strongest European opportunity is a two-tier model. Large regulated organizations need integrated EASM, exposure validation, reporting, data-sovereignty controls, and managed assistance. SMEs need a bounded package with transparent asset limits, automated reporting, minimal connector work, and optional managed remediation. IDC's finding that SMEs are the fastest-growing spending group supports the second motion, while ENISA's assessment and patching gaps show why self-service alone will often be insufficient ([12], [101]).

For buyers, a practical procurement scorecard is:

| Criterion | Recommended weight | Required evidence |
|---|---:|---|
| Discovery coverage and attribution | 20% | Seedless discovery test and ownership evidence |
| Risk context and validation | 20% | Reachability, exploitability, business importance, attack paths |
| Remediation workflow | 20% | Ticket creation, ownership, SLA tracking, closure verification |
| Integrations and API | 15% | CMDB, VM, CNAPP, SIEM, XDR, SOAR, ITSM, cloud |
| Freshness and change detection | 10% | Demonstrated update frequency and change alerts |
| Reporting and regulatory evidence | 10% | Executive, technical, and audit-ready reports |
| Sovereignty and total cost | 5% | Hosting, support access, retention, asset-band economics |

Begin with one external business perimeter and a known asset baseline. Expand only after the platform finds verified unknown assets, improves ownership, and shortens remediation. Organizations with limited SOC capacity should evaluate managed validation or MDR integration, but ENISA's MSS evidence indicates they should retain governance and risk ownership internally ([58]).

For investors and market entrants, do not size the opportunity from the 31.2% CAGR alone. Segment revenue into software subscriptions, validation or offensive testing, implementation, managed monitoring, and compliance reporting. The most defensible whitespace is likely in midmarket managed ASM, European-hosted delivery, remediation orchestration, and exposure analytics that unify existing tools rather than replace all of them.

**Decision-ready insight:** The commercial winner will not be the vendor with the largest asset list. It will be the provider that makes exposure ownership, validation, remediation, regulatory evidence, and predictable economics easiest for the customer's existing team.

## Synthesis

The European cybersecurity market combines strong aggregate expansion with constrained organizational capacity. IDC's **11.8%** growth forecast and ENISA's **EUR1.5M median security budget** show that money is available, but ENISA's hiring, SME-assessment, and patch-delay findings show that execution remains the bottleneck. ASM demand emerges from this gap: organizations cannot protect assets they cannot see, but visibility only matters when it improves an operational decision ([12], [101]).

| Strategy | Mechanism | Scope | Evidence base | Main trade-off | Time horizon |
|---|---|---|---|---|---|
| EASM | Outside-in continuous discovery and exposure assessment | Internet-facing assets | Fast-growth forecast, transparent prices, public award | Coverage and attribution can create noise | Days to months |
| VM and CNAPP | Scan known infrastructure and cloud environments | Internal, cloud, application, and workload assets | Strong software demand and NIS2 patch challenges | Misses unknown assets or nonintegrated environments | Weeks to quarters |
| SIEM and XDR | Detect and correlate active behavior | Telemetry from endpoints, identity, network, email, cloud | Threat and compliance demand | Data cost, tuning, ecosystem dependence | Seconds to months |
| MDR and MSS | Add expertise, monitoring, and response capacity | 24x7 operations and specialist services | ENISA skills and MSS evidence | External capacity does not transfer risk ownership | Contract-year horizon |
| CTEM | Repeatedly scope, discover, prioritize, validate, and mobilize | Enterprise-wide exposure program | Integrates ASM, VM, CNAPP, testing, and remediation | Requires process change and executive ownership | Multi-quarter continuous program |

The non-obvious tension is that platform consolidation and specialist innovation are both rational. Microsoft, Palo Alto Networks, CrowdStrike, Tenable, Rapid7, and IBM can reduce integration and procurement overhead by bundling ASM with broader controls. Censys, CyCognito, Outpost24, Detectify, and other specialists can outperform when discovery accuracy, regional delivery, validation, or a particular exposure class matters more than stack consolidation.

A second tension is between regulatory urgency and budget discipline. NIS2, DORA, and CRA create evidence and resilience obligations, while ENISA finds regulation to be a leading investment driver. Yet ASM is not mandated by name, and purchasing it without ownership and remediation can produce compliance theater rather than resilience. The correct investment sequence is: establish asset scope, discover continuously, validate exploitable risk, assign ownership, remediate through existing workflows, observe runtime activity through SIEM/XDR, and measure outcomes through CTEM.

The market conclusion is therefore conditional but attractive. European ASM demand should expand faster than the overall security market, and observed annual prices span from low thousands to hundreds of thousands depending on asset volume. The durable opportunity lies in connecting external discovery to remediation, managed expertise, and regulatory evidence. Buyers should fund that outcome; vendors should prove it.
