根據 Mordor Intelligence 預測,人工智慧驅動的電子郵件安全和網路釣魚偵測市場預計將從 2025 年的 62.3 億美元成長到 2026 年的 72.5 億美元,然後在 2031 年達到 123.1 億美元,2026 年至 2031 年的複合成長率為 16.68%。

本報告按元件(軟體、服務)、部署方式(雲端、本地部署、混合部署)、企業規模(大型企業等)、解決方案類型(AI安全電子郵件閘道器等)、應用領域(網路釣魚偵測等)、最終用戶產業(銀行、金融服務和保險等)以及地區進行細分。市場預測以美元計價。
這種擴張正在推動人工智慧驅動的電子郵件安全和網路釣魚偵測市場的發展,並加劇企業環境中網路釣魚和商業電子郵件詐騙(BEC) 攻擊的成本。根據 FBI 的記錄,預計 2025 年將有 24,768 起申訴,造成 30.5 億美元的損失,這些損失均由 BEC詐騙引起,這表明即使是相對較小的事件也可能造成重大的經濟損失。微軟的研究也表明,雖然 BEC詐騙僅佔所有已發現威脅的 2%,但卻佔攻擊損失的 21%,這凸顯了攻擊品質和數量在企業防禦中日益成長的重要性。 2026 年第一季,微軟威脅情報追蹤到 1,070 萬起詐騙攻擊,光是 3 月就成長了 26%,顯示威脅情況依然嚴峻。這些壓力正在推動採購行為的改變。安全團隊正在從主要過濾已知威脅的工具轉向能夠隔離可疑行為、偵測身分冒用並自動對大規模郵箱叢集進行分類的平台。在人工智慧驅動的電子郵件安全和網路釣魚偵測市場,這一趨勢正在擴大人工智慧原生供應商與仍然嚴重依賴靜態規則和基於簽名的檢查的傳統閘道器提供者之間的差距。
人工智慧驅動的電子郵件安全和網路釣魚偵測市場也受到從本地電子郵件系統轉變為雲端電子郵件和混合工作模式的影響。根據 Barracuda 的一份報告,在 2025 年 2 月分析的約 6.7 億封電子郵件樣本中,四分之一是惡意郵件或垃圾郵件。這證實了基於雲端的商業通訊仍然容易受到重大威脅。 Fortra 的一項研究發現,2025 年第二季 60% 的網路釣魚重定向頁面指向合法的登入基礎設施,並且在雲端優先環境中,基於信譽的基本過濾的有效性顯著降低。這一點意義重大,因為在 Microsoft 365 和 Google Workspace 中,電子郵件安全性已從邊界設備問題轉變為涵蓋內部電子郵件流、文件共用連結、帳戶濫用和投遞後活動的平台問題。因此,人工智慧驅動的電子郵件安全和網路釣魚偵測市場傾向於採用 API主導和混合架構,以便在不強制更改電子郵件路由的情況下檢查投遞後威脅。將閘道器控制與雲端原生偵測功能結合的供應商更具優勢。這是因為買家現在尋求的解決方案既能涵蓋交付前過濾,又能涵蓋收件匣內行為,而傳統的基於邊界的產品無法全面監控這兩方面。
在人工智慧驅動的電子郵件安全和網路釣魚偵測市場,那些已經管理著功能重疊的多層電子郵件安全工具的買家仍然抱持著抵觸情緒。進階部署通常會結合安全電子郵件閘道器、整合雲端電子郵件安全性、加密、歸檔、訓練和威脅回應工具,這可能會導致支出高於許多採購團隊最初的預期。對於中型企業而言,負擔更加沉重,因為在同一環境中堆疊多個產品使得證明年度郵箱許可費用的合理性變得困難。沒有大規模內部安全部門的團隊還面臨整合挑戰、合約複雜性和營運摩擦。在人工智慧驅動的電子郵件安全和網路釣魚偵測市場,能夠將功能整合到單一平台的供應商在克服這些障礙和簡化預算分配方面具有顯著優勢。雖然買家仍然對更強大的保護感興趣,但在大規模部署之前,許多買家都在尋求減少工具使用、降低協調成本以及建立更可預測的營運模式。
到2025年,軟體將佔據人工智慧驅動的電子郵件安全和網路釣魚偵測市場60.14%的佔有率。這反映了電子郵件保護模式正從主導裝置的方案轉向透過訂閱模式交付的雲端原生偵測引擎。軟體層的核心地位源自於企業對持續模型更新、快速部署以及在單一營運環境中實現網路釣魚偵測、交付後糾正措施和合規性管理等各個環節的共用可見性的需求。此外,軟體可以透過API和SaaS主機而非實體基礎架構進行部署,這進一步強化了軟體的地位,降低了已在使用雲端生產力套件的企業採用軟體的門檻。另外,用於過濾、調查和策略控制的獨立工具會導致許可和營運方面的重複,促使買家傾向於整合平台。 Proofpoint於2026年3月Proofpoint的整合閘道器和基於API的保護功能的計劃,正是對這一市場趨勢的體現,因為買家越來越希望獲得一個單一的、統一的平台,而不是多個分散的控制機制。
預計到2031年,服務市場將以17.92%的複合年成長率成長,這表明市場需求已從軟體授權擴展到支援、託管偵測、培訓和專家級威脅防禦營運等領域。這一成長基於一個清晰的營運現實:許多客戶尋求更強大的保護,但不想建立和擴展自己的安全營運中心(SOC)來進行電子郵件監控。託管服務供應商正在利用原生人工智慧平台提供持續監控和糾正措施,使小規模的組織無需組建大規模的內部團隊即可獲得企業級功能。持續的部署後調校、策略更新、報告和異常管理的需求進一步增強了服務市場的機會。雖然軟體仍然是人工智慧驅動的電子郵件安全和網路釣魚偵測市場的主要收入來源,但隨著買家越來越將電子郵件安全視為持續的營運功能而非獨立的產品購買,服務領域正在快速成長。
預計到 2025 年,雲端採用率將達到 53.18%,凸顯了企業電子郵件基礎架構向 Microsoft 365 和 Google Workspace 的顯著轉變。人工智慧驅動的電子郵件安全和網路釣魚偵測市場仍然是最大的細分市場,因為雲端採用消除了許多本地電子郵件系統相關的維運負擔,並支援跨分散式用戶快速部署。這也符合目前的預算和人員配置模式,因為企業往往傾向於選擇無需進行大規模基礎設施變更即可部署的解決方案。雲端優先採用模式對於標準網路釣魚過濾、基準威脅監控以及大規模郵箱環境的集中管理尤其有效。然而,買家也意識到,純雲端方案無法解決所有問題,尤其是在內部電子郵件、帳戶濫用和郵件投遞後行為是攻擊途徑的核心時。
混合部署預計到 2031 年將以 18.03% 的複合年成長率成長,成為該領域成長最快的模式。混合架構的重要性日益凸顯,因為安全郵件閘道在郵件投遞前攔截檔案式的有效載荷和大規模攻擊方面仍然具有優勢,而基於 API 的系統則擅長檢測投遞後的商業電子郵件詐騙、內部濫用和橫向機芯。隨著企業尋求使用單一、協調的營運模式來覆蓋外部邊界流量和內部租戶流量,這種組合的吸引力正在不斷增強。此外,Mimecast 的 API 賦能部署策略(以 2026 年 3 月為目標)表明,供應商正在適應買家對更快部署速度的需求,同時又不犧牲精細的檢查能力。雖然本地部署在政府、國防和金融等資料居住和主權法規仍然嚴格的領域仍然很重要,但隨著混合模式在傳統控制和雲端原生可見性之間搭建起更具可操作性的橋樑,本地部署的作用正在縮小。
預計到2025年,北美將佔據人工智慧驅動的電子郵件安全和網路釣魚偵測市場31.14%的佔有率,成為最大的區域貢獻者。這一主導地位歸功於美國極高的網路犯罪損失報告、強勁的企業安全支出以及雲端生產力工具的廣泛應用。根據FBI的記錄,預計到2025年,網路釣魚和欺騙申訴將達到191,561起,企業電子郵件詐騙的損失將高達30.5億美元。這確保了電子郵件詐騙仍然是企業安全規劃的核心關注點。此外,北美眾多知名供應商的存在促進了產品的快速測試、新架構的早期採用以及買賣雙方之間的密切回饋。加拿大和墨西哥透過擴大目標市場並提高雲端採用率以適應美國的網路安全實踐,也為區域成長做出了貢獻。
歐洲仍然是第二大成長區域,其中德國、英國和法國是主要的需求中心。該地區的成長主要受監管法規的驅動,尤其是NIS2,它迫切要求將身分驗證電子郵件控制和更廣泛的網路安全衛生管理作為營運要求。德國宣布計劃於2025年12月將NIS2納入其國家法律,這給相關營業單位帶來了緊迫的壓力,迫使其加強電子郵件安全、報告系統和合規文件。 DORA進一步加劇了金融服務業的這種壓力,導致企業在支持威脅偵測和政策合規性證明的工具上投入更多資金。雖然英國採取了與歐盟協調不同的發展路徑,但DMARC的應用和加強電子郵件管理仍然是其國家指南中的核心建議。
預計到2031年,亞太地區將以18.58%的複合年成長率成長,成為人工智慧驅動的電子郵件安全和網路釣魚偵測市場成長最快的地區。該地區正經歷快速變革,大中型企業加速採用雲端運算,同時資料保護和數位安全法律規範也日趨完善。印度、中國、日本、澳洲和東南亞的企業正在進一步發展其基於雲端的通訊基礎設施,這推動了對擴充性的、SaaS主導的電子郵件安全管理的需求。中東和非洲仍處於起步階段,但各國數位轉型計畫和隱私法規的製定正在加速其應用,尤其是在海灣市場。
According to Mordor Intelligence, the AI-Driven email security and Phishing Detection Market size is expected to grow from USD 6.23 billion in 2025 to USD 7.25 billion in 2026 and is forecast to reach USD 12.31 billion by 2031 at 16.68% CAGR over 2026-2031.

This report is Segmented by Component (Software and Services), Deployment (Cloud, On-Premises, and Hybrid), Enterprise Size (Large Enterprises, and Mor), Solution Type (AI Secure Email Gateway, and More), Application (Phishing Detection, and More), End-User Industry (BFSI, and More), and Geography. The Market Forecasts are Provided in Terms of Value (USD).
The scale is pushing forward the AI-Driven Email Security and Phishing Detection Market, and the cost of phishing and business email compromise attacks across enterprise environments. The FBI recorded USD 3.05 billion in business email compromise losses from 24,768 complaints in 2025, demonstrating that a relatively limited number of incidents can still cause significant financial damage. Microsoft also showed that business email compromise accounted for only 2% of observed threats but 21% of attack outcomes, indicating that attack quality now matters as much as attack volume for enterprise defenses. In Q1 2026, Microsoft Threat Intelligence tracked 10.7 million business email compromise attacks, and March alone saw a 26% increase, pointing to a threat environment that is still intensifying. That pressure is changing buying behavior because security teams are moving away from tools that mainly filter known threats and toward platforms that can isolate suspicious behavior, detect impersonation, and automate triage across large mailbox populations. In the AI-Driven Email Security and Phishing Detection Market, this has widened the gap between AI-native vendors and older gateway providers that still depend too heavily on static rules and signature-led inspection.
The AI-Driven Email Security and Phishing Detection Market is also being shaped by the move from on-premises mail systems to cloud email and hybrid work models. Barracuda reported that 1 in 4 emails analyzed in February 2025 were malicious or unwanted spam, based on a sample of nearly 670 million emails, confirming that cloud-based business communication still carries a heavy threat load. Fortra found that 60% of phishing redirect pages in Q2 2025 pointed to legitimate login infrastructure, making basic reputation-based filtering much less effective in cloud-first environments. This matters because Microsoft 365 and Google Workspace have shifted email security from a perimeter-appliance issue to a platform issue that encompasses internal mail flows, file-sharing links, account misuse, and post-delivery activity. The AI-Driven Email Security and Phishing Detection Market is therefore favoring API-led and hybrid architectures that can inspect threats after delivery, without forcing a disruptive change to mail routing. Vendors that combine gateway controls with cloud-native inspection are better positioned, as buyers now want coverage across both pre-delivery filtering and inbox behavior that older perimeter products cannot fully observe.
The AI-Driven Email Security and Phishing Detection Market still faces resistance from buyers who are already managing layered email security tools with overlapping functions. Advanced deployments often combine secure email gateways, integrated cloud email security, encryption, archiving, training, and threat response tools, which can push spending higher than many procurement teams initially expect. The burden is greater for midsize organizations because annual mailbox licensing can become difficult to justify when multiple products are stacked in the same environment. This also creates integration work, contract complexity, and operational friction for teams without large internal security staffs. In the AI-Driven Email Security and Phishing Detection Market, vendors that can consolidate capabilities into a single platform are better positioned to overcome this barrier and make budgets easier to defend. Buyers are still interested in stronger protection, but many want fewer tools, lower coordination cost, and a more predictable operating model before expanding adoption at scale.
Other drivers and restraints analyzed in the detailed report include:
For complete list of drivers and restraints, kindly check the Table Of Contents.
Software held 60.14% of the AI-Driven Email Security and Phishing Detection Market share in 2025, reflecting the move away from appliance-led email protection toward cloud-native detection engines delivered through subscription models. The software layer has become central because organizations want continuous model updates, faster deployment, and shared visibility across phishing detection, post-delivery remediation, and compliance controls in a single operating environment. That position is reinforced by the fact that software can be deployed via APIs and SaaS consoles rather than physical infrastructure, reducing implementation friction for enterprises that already run cloud productivity suites. Buyers are also favoring integrated platforms because separate tools for filtering, investigation, and policy control create duplication in both licensing and operations. Proofpoint's March 2026 plan to unify gateway and API-based protection reflected this market trend, as buyers increasingly want a single, coordinated platform rather than multiple disconnected controls.
Services are projected to grow at a 17.92% CAGR through 2031, indicating that demand is expanding beyond software licenses into support, managed detection, training, and specialist threat operations. This growth follows a clear operating reality, because many customers want stronger protection but do not want to build or expand their own security operations center for email monitoring. Managed service providers are using AI-native platforms to deliver continuous monitoring and remediation, enabling smaller organizations to access enterprise-grade capabilities without staffing large internal teams. The service opportunity is also strengthened by the need for ongoing tuning, policy updates, reporting, and exception management after deployment. In the AI-Driven Email Security and Phishing Detection Market, software remains the revenue anchor, but services are growing rapidly as buyers increasingly treat email security as an ongoing operational function rather than a standalone product purchase.
Cloud-only deployment accounted for 53.18% in 2025, underscoring the strong shift of enterprise email infrastructure to Microsoft 365 and Google Workspace. This part of the AI-Driven Email Security and Phishing Detection Market remained the largest because cloud deployment eliminates the operational burden of many on-premises mail systems and enables faster activation across distributed users. It also aligns with the current budget and staffing model, as organizations prefer solutions that can be activated without major infrastructure changes. Cloud-first deployment works especially well for standard phishing filtering, baseline threat monitoring, and centralized administration across large mailbox estates. Even so, buyers have recognized that cloud-only coverage does not solve every problem, especially when internal mail, account misuse, and post-delivery behavior become central parts of the attack path.
Hybrid deployment is projected to expand at an 18.03% CAGR through 2031, making it the fastest-growing model in this segment. Hybrid architecture matters because secure email gateways remain strong at stopping file-based payloads and bulk attacks before delivery, while API-based systems are better at spotting business email compromise, internal abuse, and lateral movement after delivery. That combination is becoming increasingly attractive as organizations seek to cover both external perimeter traffic and internal tenant traffic with a single, coordinated operating model. Mimecast's March 2026 API-compatible deployment push also showed that vendors are adapting to buyers who want faster rollout without abandoning deeper inspection capability. On-premises deployment still retains relevance in government, defense, and financial settings where data residency and sovereignty rules remain strict, but its role is becoming narrower as hybrid models offer a more practical bridge between legacy controls and cloud-native visibility.
North America held 31.14% of the AI-Driven Email Security and Phishing Detection Market share in 2025, making it the largest regional contributor. The region led because the United States combines very high reported cybercrime losses with deep enterprise security spending and a large installed base of cloud productivity tools. The FBI recorded 191,561 phishing and spoofing complaints in 2025, alongside USD 3.05 billion in business email compromise losses, which kept email fraud near the center of corporate security planning. North America also benefits from the presence of several well-known vendors, which supports faster product testing, earlier adoption of new architectures, and tighter feedback between buyers and providers. Canada and Mexico added to regional growth as cloud adoption and alignment with U.S. cybersecurity practices widened the addressable base.
Europe remained the second-largest regional contributor, with Germany, the United Kingdom, and France acting as major demand centers. Regional growth is being heavily shaped by regulation, especially with NIS2 requiring authenticated email controls and broader cyber hygiene as urgent operating requirements. Germany's move to transpose NIS2 into national law in December 2025 added immediate pressure on affected entities to strengthen email security, reporting discipline, and compliance documentation. DORA is reinforcing that pressure in financial services, which is raising spending on tools that support both threat detection and policy evidence. The United Kingdom is following its own path outside EU harmonization, but DMARC enforcement and stronger email controls remain central recommendations in national guidance.
Asia-Pacific is projected to expand at an 18.58% CAGR through 2031, making it the fastest-growing region in the AI-Driven Email Security and Phishing Detection Market. The region is moving quickly as cloud adoption accelerates across large and mid-sized enterprises, while regulatory frameworks are becoming more active in data protection and digital security. Enterprises in India, China, Japan, Australia, and Southeast Asia are building more cloud-based communication environments, which creates a stronger need for scalable SaaS-led email security controls. The Middle East and Africa remain early-stage contributors, but national digital transformation programs and developing privacy rules are supporting gradual adoption, especially in the Gulf markets.
