Network Security Sandbox Market Moves Toward Integrated Cloud Defense as Cato Networks Raises US$359 Million

Cato Networks raised US$359 million in Series G funding in June 2025 to accelerate platform innovation, advance AI security, and expand its global reach. Its cloud security platform includes sandboxing, which executes suspicious files in isolated environments and generates forensic reports. Although the financing supports Cato's broader security and networking business, the expansion could widen access to integrated sandbox capabilities, helping enterprises investigate evasive malware without deploying separate appliances.

The commercial opportunity spans security software providers, managed security service providers, and incident-response specialists. Cato Networks combines sandbox analysis with cloud-delivered threat prevention, while Fortinet connects FortiSandbox with its security and response products. ANY.RUN supports interactive investigations, and Joe Security provides automated and analyst-driven malware analysis. These approaches create opportunities for managed investigation services, workflow integrations, and customer acquisition. Suppliers offering isolated tools face pressure to demonstrate how their findings translate into faster, actionable responses across customers' existing security systems.

According to DataM Intelligence, the global Network Security Sandbox Market reached US$18.39 billion in 2025 and is projected to reach US$567.00 billion by 2033, growing at a CAGR of 53.46% during 2026-2033. The report identifies ransomware, phishing, distributed work environments, and demand for behavioral threat analysis as important adoption drivers.

Europe remains a major adoption center, with financial services and healthcare using sandbox analysis to strengthen protection of sensitive information. Cloud-based analysis and integration with broader security platforms are gaining traction as organizations seek scalable investigation capacity. ANY.RUN reported more than 6.8 million sandbox sessions in 2025, up 72.2% from 2024. This platform-specific increase provides a concrete usage signal for deeper malware investigation, while banking and financial services remain important customer opportunities because suspicious files and phishing can threaten transactions and customer data.

Recent Development

On May 13, 2026, Palo Alto Networks published an advisory covering arbitrary file read and deletion in WildFire appliances. The disclosure highlights why sandbox procurement must include appliance patching and lifecycle management.

On June 8, Fortinet published its FortiSandbox 5.2 feature overview, detailing faster dynamic analysis, multistage malware visibility, image intelligence and a redesigned threat dashboard.

On June 10, Zscaler announced endpoint sandbox capabilities for malicious files introduced through offline sources, including flash drives. This extends inspection beyond traditional network traffic and cloud submissions.

In June, Palo Alto Networks released inline malware prevention for Prisma Access Explicit Proxy with Advanced WildFire. Coverage includes documents, scripts, executables and archives up to 100 megabytes.

On August 17, Fortinet announced its acquisition of Virtue AI, expanding automated validation and runtime protection for AI systems.

Segmentation Analysis
Cloud-based solutions are competing on whether suspicious files can be blocked before reaching users. Palo Alto Networks' June release illustrates this shift toward inline prevention. Purchasing decisions therefore need to consider supported file types, verdict speed and enforcement configuration together. A cloud service's detection capability delivers limited value if relevant traffic never reaches its analysis pipeline.

Appliance and hybrid deployments retain relevance where organizations need local analysis of sensitive documents. WildFire allows customers to route selected files to private infrastructure while sending other samples to public clouds. Fortinet's 3000G appliance supports 150 virtual machines. Capacity planning must account for concurrent submissions and inspection delays, rather than hardware throughput alone.

Services and platform integration create opportunities around configuration, migration and operating costs. TrendAI Vision One Sandbox Analysis uses monthly credits, making submission volume commercially relevant. Integration work also determines whether email, endpoint and network controls share verdicts effectively. Buyers should compare the cost of protected workflows, including administration, against isolated sandbox license prices.

USA Market
American suppliers are embedding sandboxing within broader cloud and network security platforms. Zscaler's endpoint expansion addresses an exposure that network-only inspection can miss: files arriving through removable media. Palo Alto Networks also provides government-specific analysis environments and configurable forwarding of decrypted traffic. These choices make deployment design central to purchasing. Federal and commercial customers need to verify which analysis environment receives samples, which channels are inspected and how quickly enforcement follows a verdict. Integration expertise can therefore influence supplier selection as much as detection claims.

Japan Market
Japan presents a migration opportunity. Trend Micro lists December 31, 2026, as the support-end date for Sandbox as a Service for Deep Discovery Inspector Virtual Appliance, identifying Vision One Sandbox Analysis as its successor. Customers must review migration procedures and continuing inspection coverage before that deadline. Palo Alto Networks also offers a Japan analysis cloud, but its documentation cautions that sample-processing locations can differ from Prisma Access compute locations. Japanese buyers should therefore examine file-routing settings, regional capabilities and contractual data handling, rather than assuming local connectivity guarantees local processing.

Company Profiles

Fortinet reported 2025 revenue of $6.80 billion. FortiSandbox integrates with FortiGate, FortiMail and other Security Fabric products. Version 5.2 advertises dynamic scans up to six times faster, with appliance capacity and integration supporting enterprise deployment.

Palo Alto Networks supplies Advanced WildFire through public, private and hybrid deployment models. Its combination of static, dynamic and machine-learning analysis supports unknown-malware detection. Regional clouds and policy-based file routing provide flexibility, while configuration and maintenance remain operational responsibilities.

Trend Micro offers Vision One Sandbox Analysis within its security platform. Monthly-credit requirements connect spending to usage. Its published migration path from legacy sandbox services creates opportunities for deployment assistance, submission-policy optimization and continuity planning.
