美國網路安全：市場佔有率分析、行業趨勢和統計數據以及成長預測（2026-2031 年）

美國網路安全市場預計將從 2025 年的 927.3 億美元成長到 2026 年的 997.9 億美元，到 2031 年達到 1,440.7 億美元，2026 年至 2031 年的複合年成長率為 7.62%。

這項成長主要受聯邦政府零信任指令、針對關鍵基礎設施的勒索軟體攻擊激增以及雲端遷移加速推動，目前已有94%的組織採用多重雲端環境。儘管如此，本地部署架構仍然佔據最大佔有率，因為國防、金融服務和醫療保健行業的企業仍在維護必須保持本地控制的舊有系統。然而，隨著企業尋求可擴展的保護和即時威脅情報，雲端交付的安全解決方案正以15%的複合年成長率持續成長。創投持續推動創業投資，預計到2024年，美國網路安全Start-Ups將獲得116億美元的投資，其中大部分將用於開發能夠減輕分析師工作量的AI驅動型威脅偵測平台。美國證券交易委員會（SEC）強制性的資料外洩揭露規則、不斷上漲的網路保險費以及持續的人才短缺等因素共同作用，強化了長期需求，使美國網路安全市場成為公共和私營部門的戰略重點。

美國網路安全市場趨勢與洞察

聯邦零信任指令加速各機構安全現代化進程

第14028號行政命令強制所有民事機構採用零信任架構，啟動了一項為期多年的現代化計劃，該項目的影響也將波及州和地方政府。國防安全保障部近期向ASRC Federal公司授予1700萬美元，用於美國公民及移民服務局（USCIS）的整合服務；財政部新推出的200億美元PROTECTS計畫也展現了聯邦政府的強大採購能力。已有23個州發布了零信任藍圖，其中加州累計5000萬美元，旨在到2026年實現所有機構以身分為中心的管理。承包商也必須效仿，將零信任要求深入國防和金融服務供應鏈的各個環節。這種連鎖反應使美國網路安全市場成為持續公共部門支出的最大受益者。

針對中型醫療和教育機構的勒索軟體攻擊激增

2024年2月，Change Healthcare的資料外洩事件導致6.7萬家藥局的處方箋處理系統癱瘓，聯合健康集團（UnitedHealth Group）為此支付了23億美元的補救費用。三個月後，Ascension Health也遭遇了類似的危機，勒索軟體攻擊癱瘓了旗下140家醫院的電子健康記錄系統。美國衛生與公眾服務部證實，去年有1億份病患紀錄遭洩露，增加了聯邦政府對醫院升級防禦系統的壓力。教育機構同樣面臨風險，聯邦調查局（FBI）報告稱，由於勒索軟體攻擊導致學生服務資料庫被清除，多所學校被迫關閉。這些事件加劇了網路安全投入的迫切性，預計網路安全領域的複合年成長率將達到14.6%，遠超美國整體網路安全市場的成長速度。

各州隱私法規的碎片化使供應商合規性變得複雜。

加州的《加州消費者隱私法案》(CCPA)、維吉尼亞的《消費者資料保護法案》(CDPA) 和康乃狄克州的《消費者資料保護和揭露法案》(CTDPA) 各自對資料外洩通知和消費者權益提出了不同的要求，迫使供應商必須遵守各州的合規規定。美國證券交易委員會 (SEC) 修訂後的《SP條例》要求金融機構在資料外洩發生後 30 天內通知個人，這與各州更為嚴格的期限有所重疊。中型安全服務提供商報告稱，其每年平均合規成本高達 230 萬美元，這擠壓了利潤空間並阻礙了市場准入。監管碎片化減緩了產品部署速度，使產品上市計劃更加複雜，預計將使美國網路安全市場的複合年成長率 (CAGR) 下降約 1.2 個百分點。

細分市場分析

解決方案是主要的收入驅動力，預計到2025年將占美國網路安全市場佔有率的67.30%，而託管服務預計到2031年將以15.1%的複合年成長率成長。在聯邦政府推行零信任政策後，身分和存取管理（IAM）的採用率激增，而隨著容器化開發平臺的普及，應用安全支出也隨之成長。網路安全設備正被軟體定義替代方案所取代，而終端保護正在演變為XDR套件，該套件可從筆記型電腦、伺服器和行動裝置收集遙測資料。雲端安全子類別，尤其是雲端原生應用程式保護平台（CNAPP），正經歷最快的成長，這反映了傳統工具無法應對的多重雲端環境的複雜性。專業服務在合規性審核和事件回應方面保持著強大的市場地位，但人才短缺正在限制其服務能力並推高計費成本。

託管服務的成長主要受人才嚴重短缺和監管壓力的驅動，迫使即使是資源雄厚的公司也尋求外部專業知識。資安管理服務供應商 (MSSP) 擴大以訂閱形式提供安全營運中心 (SOC) 功能，降低了中型企業的准入門檻。工具疲勞也影響產品組合：90% 的大型企業運行功能重疊的漏洞掃描器，並正在整合到一個統一的平台上。供應商透過整合人工智慧分析和編配功能來應對這項挑戰，從而增強解決方案的採用率並提高每位客戶的平均收入。因此，解決方案保持了規模，而服務則推動了美國網路安全市場更高的成長率。

到2025年，本地部署環境將佔總收入的57.20%，這主要受國防、金融服務和醫療保健產業維護資料主權和傳統系統整合的迫切需求所驅動。聯邦機構繼續在空氣間隙環境中維護機密網路，但分析層正擴大遷移到商業雲。摩根大通等金融機構正在投資混合架構，將本地金鑰管理與雲端原生偵測功能結合，以確保合規性，同時又不犧牲靈活性。

受資本支出減少、彈性擴展和軟體即服務 (SaaS) 部署速度加快的推動，雲端交付安全解決方案以 14.4% 的複合年成長率 (CAGR) 實現成長。與基於設備的替代方案相比，採用 SECaaS 的企業實施週期縮短了 40%，從而加快了風險緩解速度。供應商整合威脅情報來源和行為分析，提供持續更新的控制平面，以適應不斷演變的攻擊者技術。隨著時間的推移，這種成長差距擴大了收入差距，導致儘管高度監管行業的絕對支出趨於穩定，但本地部署方案在美國網路安全市場的佔有率仍然相對下降。

第7章 市場機會與未來展望

The US cybersecurity market is expected to grow from USD 92.73 billion in 2025 to USD 99.79 billion in 2026 and is forecast to reach USD 144.07 billion by 2031 at 7.62% CAGR over 2026-2031.

This expansion is fueled by federal zero-trust mandates, a sharp increase in ransomware attacks on critical infrastructure, and accelerated cloud migration that now places 94% of organizations in multi-cloud settings . On-premise architectures still hold the largest deployment footprint because defense, financial services, and healthcare operators retain legacy systems that must remain behind local controls; however, cloud-delivered security is advancing at a 15% CAGR as enterprises seek scalable protection and real-time threat intelligence. Venture capital continues to stimulate innovation, with USD 11.6 billion invested in US cyber start-ups during 2024, much of it channeled into AI-driven threat-detection platforms that reduce analyst workload. Mandatory SEC breach-disclosure rules, rising cyber-insurance premiums, and a persistent talent shortage collectively reinforce long-term demand, positioning the US cybersecurity market as a strategic priority for both public and private sectors.

US Cybersecurity Market Trends and Insights

Federal Zero-Trust Mandates Accelerating Security Modernization Across Agencies

Executive Order 14028 obliges every civilian agency to adopt zero-trust architecture, triggering multi-year modernization projects that ripple through state and local governments. The Department of Homeland Security recently awarded USD 17 million to ASRC Federal for USCIS integration services, and the Treasury's new USD 20 billion PROTECTS vehicle underscores federal buying power. Twenty-three states have published their zero-trust roadmaps, with California allocating USD 50 million for identity-centric controls across all agencies by 2026. Contractors must follow suit, extending zero-trust requirements deep into defense and financial services supply chains. The cascade effect positions the US cybersecurity market as the primary beneficiary of sustained public-sector spending.

Surge in Ransomware Attacks Targeting Mid-Market Healthcare and Education Institutions

Change Healthcare's February 2024 breach halted prescription processing for 67,000 pharmacies and cost UnitedHealth Group USD 2.3 billion in remediation. Ascension Health faced a similar disruption three months later when a ransomware attack paralyzed electronic health-record systems across 140 hospitals. The Department of Health and Human Services confirmed that 100 million patient records were exposed last year, fueling federal pressure on hospitals to modernize defenses. Educational institutions are equally vulnerable; the FBI attributes multiple campus closures to ransomware that erased student-services databases. These events amplify spending urgency, pushing healthcare security outlays to an expected 14.6% CAGR, well above the overall US cybersecurity market trajectory.

Fragmented State-Level Privacy Regulations Creating Compliance Complexity for Vendors

CCPA in California, CDPA in Virginia, and CTDPA in Connecticut impose divergent breach-notification and consumer-rights requirements that force vendors to maintain state-specific compliance frameworks. The SEC's amended Regulation S-P now obliges financial institutions to notify individuals within 30 days of a data compromise, overlapping with stricter state deadlines. Mid-market security providers report average annual compliance costs of USD 2.3 million, eroding margins, and deterring market entry. Fragmentation slows product rollouts and complicates go-to-market planning, shaving an estimated 1.2 percentage points from the US cybersecurity market CAGR.

Other drivers and restraints analyzed in the detailed report include:

1. Adoption of 5G and Edge Computing Expanding the Threat Surface for Critical Infrastructure
2. Rapid Migration to SaaS and Multi-Cloud Driving Demand for Cloud-Native Security Platforms
3. Acute Talent Shortage Elevating Labour Costs and Project Timelines

Segment Analysis

Solutions remain the primary revenue driver, holding 67.30% of the US cybersecurity market share in 2025, while managed services are forecast to grow at a 15.1% CAGR through 2031. Identity and access management adoption surged after federal zero-trust directives, and application security spending expanded alongside containerized development pipelines. Network security appliances face displacement from software-defined alternatives, whereas endpoint protection evolves toward XDR suites that ingest telemetry from laptops, servers and mobile devices. Cloud-security subcategories-particularly cloud-native application protection platforms (CNAPP)-post the fastest acceleration, reflecting multi-cloud complexity that legacy tools cannot address. Professional services hold a resilient niche in compliance audits and incident response, though the labor shortage constrains capacity and pushes billable rates higher.

Managed services growth stems from acute talent constraints and regulatory pressures that force even resource-rich enterprises to seek external expertise. MSSPs increasingly deliver security-operations-centre (SOC) functions via subscription, lowering entry thresholds for mid-market businesses. The offering mix is also shaped by tool-sprawl fatigue: 90% of large organizations run overlapping vulnerability scanners that they now seek to consolidate into integrated platforms. Vendors respond by embedding AI analytics and orchestration features, reinforcing solution stickiness and expanding average revenue per customer. Consequently, solutions retain scale, while services inject higher growth velocity into the overall US cybersecurity market.

On-premises setups accounted for 57.20% of revenue in 2025, largely because defence, financial-services and healthcare sectors must preserve data sovereignty and legacy integrations. Federal agencies continue to maintain classified networks behind air-gapped environments, although analytics layers increasingly migrate to commercial clouds. Financial institutions such as JPMorgan Chase invest in hybrid architecture that combines on-premises key-management with cloud-native detection, ensuring regulatory compliance without sacrificing agility.

Cloud-delivered security solutions expanded at a 14.4% CAGR, buoyed by reduced capital spending, elastic scaling and the speed of software-as-a-service rollouts. Organizations deploying SECaaS report implementation cycles 40% shorter than appliance-based alternatives, accelerating time to risk reduction. Providers integrate threat-intelligence feeds and behavioral analytics, delivering a continuously updated control plane that adapts to evolving attacker techniques. The growth differential widens the revenue gap over time, causing the on-premises slice of the US cybersecurity market to contract in relative terms, even as absolute spending remains stable in compliance-heavy industries.
