CASB Security
That Controls Every
Cloud App You Use
Employees use 1,000+ cloud apps — most unknown to IT. NetNXT CASB gives you complete visibility into every sanctioned and unsanctioned cloud service, enforces data policies in real time, and eliminates shadow IT risk before it becomes a breach.
The Enterprise Standard for Cloud Application Security
A Cloud Access Security Broker (CASB) is the security enforcement point between your users and every cloud service they access. As the leading cloud access security broker platform for Indian and global enterprises, NetNXT CASB gives you complete visibility, granular data controls, and automated compliance enforcement across all SaaS, IaaS, and PaaS environments — whether your team is in office, remote, or hybrid.
With the average enterprise now using over 1,000 cloud applications — and IT knowing about fewer than 100 of them — CASB security is no longer optional. CASB sits between users and cloud providers, discovering unauthorised app usage, classifying sensitive data, preventing exfiltration, and generating audit trails that compliance teams actually trust.
Visibility & Shadow IT Discovery
Discover every cloud service in use — sanctioned or not. Risk-score each app across 70+ security attributes and govern or block high-risk shadow IT before a breach occurs.
Data Loss Prevention (DLP)
Identify and protect sensitive data in motion and at rest across cloud apps. Apply encryption, tokenisation, and access controls to prevent data exfiltration by insiders or external actors.
Threat Protection & UEBA
Detect advanced cloud threats, compromised accounts, malware uploads, and anomalous user behaviour using built-in User and Entity Behaviour Analytics (UEBA) across all cloud platforms.
Compliance Automation
Automate compliance monitoring and reporting for GDPR, HIPAA, PCI-DSS, SOC 2, ISO 27001, and NIST across all your cloud services. Generate audit evidence in hours, not weeks.
Real-Time Policy Enforcement
Block, alert, or quarantine cloud activity in real time. Enforce context-aware access policies based on user identity, device posture, location, and data sensitivity — without impacting productivity.
Cloud Risk Analytics
Continuous risk scoring across all cloud applications with usage analytics, data access pattern monitoring, and executive-ready dashboards that map cloud risk to business impact.

Frequently Asked Questions
A Cloud Access Security Broker (CASB) is a security policy enforcement point placed between your enterprise users and every cloud service they access. According to Gartner's original CASB definition, the four core pillars are visibility, data security, threat protection, and compliance. CASB solutions monitor all cloud application usage — including unauthorised shadow IT — and enforce policies that prevent data leakage, detect insider threats, and ensure regulatory compliance. Learn more: CASB vs SASE for Data Protection
CASB discovers shadow IT by analysing network traffic logs from firewalls, proxies, and SIEMs, alongside DNS query data and endpoint agent telemetry. Each discovered cloud service is then risk-scored across 70+ attributes including data handling practices, certifications, user access controls, and geographic data residency. Security teams can then govern, monitor, block, or redirect high-risk shadow IT — all from a centralised policy engine. Read: Shadow IT & CASB Best Practices
A Secure Web Gateway (SWG) filters all web and internet traffic in real time, blocking malicious sites and enforcing acceptable-use policies at the network level. A CASB focuses specifically on cloud application security — providing deep API-level visibility into SaaS activity, enforcing data-sharing policies, detecting insider threats, and generating compliance evidence. CASB and SWG are complementary capabilities both included in a full SASE architecture. See: Secure Web Gateway
NetNXT CASB supports three deployment modes: API Mode (direct integration with cloud service APIs for comprehensive visibility without network changes), Inline Proxy Mode (real-time traffic inspection for immediate threat prevention and policy enforcement), and Hybrid Mode (combining both for maximum coverage across sanctioned and unsanctioned apps). Our architects help you design the right architecture during the initial assessment.
CASB automates compliance by classifying sensitive data in cloud apps, enforcing data residency policies, controlling who can access or share regulated data, and generating immutable audit trails for evidence collection. NetNXT CASB includes pre-built compliance packs for GDPR, HIPAA, PCI-DSS, SOC 2, and ISO 27001 — reducing manual audit preparation time by up to 70%. Read: CASB Integration for Compliance
SASE (Secure Access Service Edge) is a cloud-delivered security architecture that converges multiple network security functions — CASB, SWG, ZTNA, FWaaS, and SD-WAN — into a single unified cloud service. CASB is one of the four core components of SASE, responsible specifically for cloud application visibility, data security, and compliance. NetNXT delivers CASB both as a standalone service and as a native component of an integrated SASE architecture. See: CASB vs SASE for Data Protection
CASB focuses on user and data activity within cloud applications — controlling access, preventing data leakage, and detecting threats from within SaaS and cloud platforms. CSPM focuses on infrastructure-level misconfiguration in IaaS environments like AWS, Azure, and GCP. Both are necessary: CASB protects data and users; CSPM protects cloud infrastructure configuration. Read: Why CSPM Tools Are Not Enough
Yes. NetNXT CASB integrates natively via API with Microsoft 365, Google Workspace, Salesforce, AWS, Azure, Box, Dropbox, Slack, Zoom, and 15,000+ other SaaS and IaaS platforms — with pre-built connectors active within 48 hours. REST API and Syslog connectors are available for custom enterprise applications. No network changes are required for API-mode deployments.
