Zscaler

Zscaler is security-as-a-service firm that offers cloud-delivered solutions for protecting user devices and data. The firm uses 150 colocation data centers to deliver appliance-based security functionality, such as firewalls and sandboxes, as a cloud-native platform. The firm focuses on enterprise customers and its internet and network access applications. The network access solutions provided by Zscaler are developed to create fast, secure connections between users and applications regardless of device, location, or network.

Zscaler delivers unified, carrier-grade internet security, next generation firewall, web security, sandboxing/advanced persistent threat (APT) protection, data loss prevention, SSL decryption, traffic shaping, policy management, and threat intelligence to its estimated 5,000 customer organizations and more than 13 million individual users worldwide.

In March of 2018, Zscaler listed shares of the company on Nasdaq under the ticker symbol of ZS. The filing for the IPO was confidential, and opened at a price of $16 per share. By the end of the day of trading, the shares were up to $33 per share.

Zscaler's platform is based on zero trust exchanges, which work to enable fast and secure connection for an organization's employees from anywhere through the internet as a corporate network. This is based on the zero trust principle of least-privileged access, which provides security with context-based identity and policy enforcement.

This zero trust architecture underpins Zscaler's platform, which the company suggests can help accelerate business by reducing cost and complexity, as deployments and management do not require VPNs or firewall rules. It works to deliver ease of use on the management and optimization of connections through cloud applications; to eliminate internet attack surfaces, with applications sitting behind the exchange to prevent discovery and targeted attacks; and to prevent the lateral movements of threats to connect users to apps without network access to isolate threats.

Zscaler emphasizes the company's adherence to security, availability, and privacy standards to help foster confidence with customer companies. This includes ensuring that all Zscaler products are aligned and certified against internationally recognized government and commercial standards-frameworks to build confidence. Zscaler holds the following commercial certifications:

• ISO 27001
• ISO 27701
• ISO 27018
• ISO 27017
• SOC 2
• SOC 3
• CSA-Star

Zscaler holds the following global government certifications:

• FedRAMP
• FIPS 140-2
• IRAP
• ITAR
• CJIS
• VPAT/Section 508
• NCSC Certificate
• TIC 3.0 Vendor Overlay
• NIST 800-63C

And Zscaler emphasizes that the company works in compliance with privacy standards set out by the European Union's GDPR, Japan's APPI, Canada's PIPEDA, Australian and New Zealand Data Privacy, California's CCPA, and the Privacy Shield agreement between the United States and the European Union.

Zscaler's Client Connector works to enable hybrid work with fast, secure, reliable access to applications from devices worldwide. The Client Connector, which was previously just the Zscaler app, is a lightweight application that sits on the endpoint device to allow users to work from anywhere. Whether users use a corporate-managed, BYOD, POS system, or RF scanner, traffic is automatically forwarded to the closest Zscaler service edge and would determine if a user is looking to access the open internet, a software-as-a-service app, or an internal app running in a public or private cloud or data center. This traffic is then automatically routed through the Zero Trust service. These services include the Zscaler Internet Access or Zscaler Private Access.

Zscaler Internet Access (ZIA) is a cloud-delivered security stack as a service that moves to the cloud and allows users and locations to get security regardless of location. This also enables direct-internet connections to a cloud security platform to secure the user experience but without sacrificing the speed of the user experience. And with a cloud-delivered service, Zscaler suggests ZIA can reduce backhauling and appliance costs, improve network performance and latency, and simplify network administration.

The Zscaler cloud security platform is capable of scaling to a customer's traffic demands without hardware or software to deploy, and is capable of processing up to 160 billion transactions at peak periods and perform 175,000 unique security updates daily. The administration portal offered by Zscaler can also help users find and stop botnets, malware, and zero days with a few clicks.

Similar to ZIA, Zscaler Private Access (ZPA) offers a zero trust network access for private applications. The cloud service provides the zero trust access running on public cloud or within a data center. With ZPA, applications are never exposed to the internet and makes applications invisible to unauthorized users. And it enables applications to connect to users through an inside-out connectivity rather than extend the network to them, which can be supported on managed and unmanaged devices and any private applications.

Zscaler B2B is a cloud-based service to provide business customers fast, seamless, and secure access to applications over the internet, regardless if they are hosted in the data center or public and private clouds. The service is based on a zero trust network access architecture and uses business policies to connect an authenticated customers to an authorized application, without exposing the app to the internet or bring a customer onto a private network.
