Cloud Security Protects Business Where It Lives
Your applications are in the cloud, and users are everywhere. Your cybersecurity can’t be tied to the data center.
Why cloud security?
Security for everyone on the network
Traditional network security made sense when all your applications were hosted in the data center and users were all on the network. Today, with apps moving to the cloud and users increasingly mobile, the stacks of appliances sitting in your data center are increasingly irrelevant. This model forces all traffic through the centralized data center for security and access controls—a complex configuration that results in a terrible user experience.
SaaS applications like Microsoft 365 were designed to be accessed directly through local internet breakouts. Zscaler cloud security enables local breakouts with full security controls.
Zscaler delivers the DMZ as a service—with antivirus, next-gen firewall, sandbox, advanced threat protection, URL filtering, SSL inspection, and more—all in a unified platform service. It’s airtight security without the cost and complexity of stacks of appliances, and it delivers a fast, secure user experience no matter where your users are.
How is cloud security different from traditional network security?
Digital transformation has changed the way people work. The corporate network perimeter is now the entire internet, and the only way to offer users comprehensive protection, no matter where they connect, is to move security and access controls to the cloud.
With tens of thousands of new phishing sites arriving every day, legacy appliances can’t keep up. The Zscaler cloud receives 200,000+ security updates every day to protect you from rapidly evolving malware while minimizing your costs and eliminating the complexity of hardware and software lifecycles.
Built into a unified cloud native platform, Zscaler security controls communicate with each other in real time to give you a cohesive picture of all the traffic moving across your network. Through a single interface, you can gain insight into every request—by user, location, and endpoint around the world—in seconds.
UBIQUITOUS

The Zscaler cloud scans every byte coming and going, including SSL and CDN traffic.
INTELLIGENT
The Zscaler cloud learns from every user and connection, so any new threat is blocked for all.
Aren’t my cloud apps and data already secure?
Yes and no. Public cloud service providers—like Amazon Web Services (AWS), Google Cloud, or Microsoft Azure—bear the security responsibility for your data within their cloud environments, but not all providers offer the same protections. You need full security controls and authentication/access management to protect your users from risky applications and prevent data exfiltration and other security challenges. A cloud access security broker (CASB) provides risk scoring for many cloud applications, which you can use to create access policies. Zscaler CASB can also augment a cloud security platform by securing cloud data in motion (via proxy) and at rest (via APIs) to prevent leaks. However, on its own, CASB does not protect against data breaches, ransomware, or other internet-borne security threats.
What about hybrid solutions?
As your organization uses more cloud-based applications and moves to cloud infrastructure services like Azure or AWS, it makes sense to have your traffic secured in the cloud as well. For legacy vendors whose bottom lines depend on selling on-premises hardware, this poses an issue. This is why they promote hybrid cloud solutions, wherein appliances handle data center security while similar security stacks (housed in cloud computing environments) handle mobile and branch security.
Unfortunately for cloud users and admins, hybrid and multicloud strategies further complicate enterprise security instead of simplifying it, and they get none of the benefits only a global multitenant cloud architecture can offer—things like speed, scale, and global visibility and threat intel. Beyond that, hybrid deployments leave more room for misconfiguration of permissions and security policies, and it can be more challenging to meet compliance requirements for data sovereignty laws (such as GDPR) or industry regulations (such as HIPAA or PCI DSS).
Components of the Zscaler cloud security solution
Zscaler takes the headaches out of cloud workload security management. Built on an innovative zero trust architecture, Zscaler Cloud Protection combines four natively integrated data protection solutions, enabling your organization to:
- Secure workload configurations and permissions with Zscaler Workload Posture
- Secure user access to private apps in the cloud with Zscaler Private Access
- Secure app-to-app connections with Zscaler Workload Communications
- Eliminate lateral threat movement with Zscaler Workload Segmentation
Working together, these solutions can help you eliminate up to 90% of your security policies and reduce your costs by 30% or more. Ultimately, you'll minimize your attack surface, simplify your security strategy with automation, and dramatically lower your security risk.

Protecting users with consistent and enforceable policies requires much more than simple URL or web filtering. That’s why thousands of organizations have already moved their IT security from appliances to security controls in the cloud. Here are some of the differences between appliance-based security and a cloud-delivered approach.
APPLIANCE-BASED SECURITY
CLOUD-BASED SECURITY
Enterprise-wide protection
APPLIANCE-BASED SECURITY
Requires security stacks at all egress points or backhauling traffic over costly MPLS links from branch offices and remote sites to DMZs. Mobile users go unprotected.
CLOUD-BASED SECURITY
Users get the same protection, whether they’re in the HQ, branch offices, on the road, or at home.
Integrated security
APPLIANCE-BASED SECURITY
Point appliances from different vendors work in isolation, so there’s no simple way to aggregate their data.
CLOUD-BASED SECURITY
Integrated security controls and cloud services correlate information to give you a complete picture of your entire network.
User experience
APPLIANCE-BASED SECURITY
Every appliance between your users and the internet causes latency. If users have to VPN into the data center, their experience is even worse.
CLOUD-BASED SECURITY
Zscaler provides fast local breakouts, and our single-scan multi-action technology enables our security services to scan simultaneously for faster performance.
IT complexity
APPLIANCE-BASED SECURITY
Deploying and maintaining appliances from multiple security vendors is expensive and difficult, requiring continuous patching, updates, and hardware upgrades.
CLOUD-BASED SECURITY
Cloud security consolidates point products into an integrated platform; there's no hardware or software to buy or manage.
Intelligence
APPLIANCE-BASED SECURITY
Point products generally apply a single technique to identify threats and pass the data on to the next appliance. Patches are applied as they become available.
CLOUD-BASED SECURITY
Cloud intelligence means that any time a threat is detected anywhere in the cloud, protection is deployed everywhere. Zscaler applies more than security updates to its cloud every day.
Value
APPLIANCE-BASED SECURITY
Appliances are expensive to buy and own, and as threats increase, you're forced to buy more of them.
CLOUD-BASED SECURITY
Zscaler moves security from capex to opex for about the price of a cup of coffee per user per month.
