Cloud security protects business where it lives

Best cloud security solution from Zscaler for enterprise protection

What is cloud security?


As organizations deploy cloud services like Office 365, they are discovering unique opportunities for collaboration and productivity. And it’s understood that these benefits are due to the cloud-based nature of these services. If they were offered only to mobile users, while the headquarters office retained its legacy Office applications, the productivity gains would be negated.

You can look at cloud security in a similar fashion. It is best when deployed across an enterprise, because the cloud offers so many advantages in terms of integrated security, simplicity, cost containment, policy enforcement, visibility and reporting, and user experience.

How does cloud security differ from “traditional” network security?

Cloud security offers many of the same services as legacy systems, such as antivirus engines, firewalls, sandboxing, data loss prevention, and others. It’s all built in to a unified platform, so the services communicate with each other, giving you visibility into the entire network from a single interface. The cloud is:

Cloud delivery of an integrated security platform provides big opportunities for CISOs to reduce latency and costs, while at the same time improving their security posture.

The cloud is always reachable from anywhere, any time, from any device.


You can add new features and thousands of users without breaking a sweat.


Security and other services talk to each other so you get full visibility.


The cloud scans every byte coming and going, including SSL and CDN traffic.


The cloud learns from every user and connection; any new threat is blocked for all.

Cloud services have experienced a 35% five-year compound annual growth rate, while on-premises appliances have only grown by 6% during the same period.

Why cloud security offers better protection than appliances

Organizations understand that protecting users with a consistent and enforceable policy requires much more than simple URL or web filtering. Thousands of companies have already switched their IT security from appliances to experience the benefits of cloud security. HERE’S WHY:

Enterprise-wide protection


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.


Every user gets the same protection, whether they’re in the HQ, branch offices, on the road, or at home.

Integrated security


Point appliances from different vendors work in isolation, so there’s no simple way to aggregate their data.


Integrated cloud security services correlate information to give you a complete picture of your entire network.

User experience


Every appliance between your users and the Internet causes latency. If users have to VPN into the data center, their experience is even worse.


Zscaler provides fast local breakouts, and our single-scan multi-action technology enables our security services to scan simultaneously for faster performance.

IT complexity


Deploying and maintaining appliances from multiple security vendors is expensive and difficult, with updates, patches, and hardware upgrades.


Cloud security consolidates point products into an integrated platform; there's no hardware or software to buy or manage.



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 intelligence means that any time a threat is detected anywhere in the cloud, protection is deployed everywhere. Zscaler applies more than 100,000 security updates to its cloud every day.



Appliances are expensive to buy and own. And, as threats increase, you are forced to buy more and more of them.


Zscaler moves security from CAPEX to OPEX — for about the price of a cup of coffee per user per month.

What about “hybrid” solutions?

As organizations move to cloud-based services, like Office 365, it makes sense to have your traffic secured in the cloud as well. For legacy security vendors who have been — and largely still are — selling on-premises hardware appliances, this reality poses a problem, because their bottom lines, and their duty to shareholders, involves moving boxes. This is why they’ve begun promoting so-called “hybrid solutions,” with data center security being handled by appliances, and mobile or branch security being handled by a similar security stack housed in the cloud.

The problem with such a strategy is that it complicates, rather than simplifies, enterprise security, and you get none of the benefits of a true cloud solution, benefits that can only be provided through a multi-tenant global architecture.
