Zscaler (ZS): Securing the Future of Cloud and Cybersecurity

Company History and Overview

Zscaler was incorporated in 2007 during the early stages of cloud adoption and mobility. The company was founded with the vision that the internet would become the new corporate network as the cloud became the new data center. At the time, traditional perimeter security approaches were providing inadequate protection for users and data as organizations rapidly adopted cloud applications and had an increasingly mobile workforce.

Zscaler pioneered a cloud platform, the Zscaler Zero Trust Exchange, that represented a fundamental shift in the architectural design and approach to networking and security. The company generates revenue primarily from selling subscriptions to access its cloud platform, along with related support services. Zscaler's subscription pricing is primarily calculated on a per-user basis, and revenue is recognized ratably over the life of the contract, which is generally one to three years.

Over the years, Zscaler has faced several challenges as it has grown its business. In its early days, the company had to educate the market on the benefits of cloud-based security compared to traditional on-premises appliance-based solutions. This sales process was often lengthy as many organizations were entrenched in using appliance-based security products. Additionally, Zscaler had to build trust with customers as a new provider of a mission-critical security service.

As Zscaler expanded internationally, it encountered risks and challenges related to operating in multiple jurisdictions, including complying with various data protection, privacy and security laws and regulations. The company also faced competition from larger networking and security vendors that offered competing cloud-based and on-premises solutions. Despite these challenges, Zscaler continued to grow its customer base, which included many large enterprises and government agencies that relied on its cloud platform to support their digital transformation initiatives.

The company's flagship offering, the Zscaler Zero Trust Exchange, provides a secure, scalable, and highly reliable cloud architecture that protects users, applications, and data, regardless of their location or device.

Zscaler's platform is built on a multi-tenant, globally distributed cloud infrastructure, which enables it to process over 500 trillion transactions per day, a staggering feat that underscores its market leadership and technological prowess. This proprietary data lake fuels the company's advanced analytics and artificial intelligence (AI) capabilities, allowing Zscaler to constantly adapt and strengthen its security solutions.

Product Segments and Offerings

Zscaler operates primarily in two main product segments:

1. Cloud Security Platform Segment: This is Zscaler's core business, accounting for approximately 98% of total revenue in the first three quarters of fiscal year 2024. The segment includes two flagship products:

a) Zscaler Internet Access (ZIA): This is Zscaler's cloud-delivered security service that helps organizations securely connect users to applications regardless of device or location. ZIA provides secure internet and web gateway, cloud firewall, SSL/TLS inspection, and cloud sandbox capabilities.

b) Zscaler Private Access (ZPA): This is Zscaler's cloud-delivered zero trust network access service that connects users, devices, and applications securely without the need for traditional VPNs. ZPA enables secure access to internally-managed applications, as well as SaaS applications.

2. Other Segment: This segment primarily consists of professional services, accounting for the remaining 2% of total revenue. These services include activities such as mapping, implementation, network design, and training.

For the nine months ended April 30, 2024, the cloud security platform segment generated revenue of $1.57 billion, up 36% year-over-year, with an impressive gross margin of 81%.

Financial Performance and Growth

Zscaler's financial performance has been nothing short of remarkable, with the company consistently delivering strong top-line growth and impressive profitability. In the most recent fiscal year (2024), the company reported revenue of $2.17 billion, representing a 34% year-over-year increase. Despite the challenging macroeconomic environment, Zscaler has maintained its momentum, further solidifying its position as a dominant player in the cloud security space.

The company's customer base has also experienced significant expansion, with Zscaler now serving nearly 8,700 customers, including over 35% of the Fortune Global 2000 companies and more than 40% of the Fortune 500. This customer diversification and loyalty have been pivotal in driving the company's growth, as evidenced by its impressive dollar-based net retention rate of 115%.

In the most recent quarter (Q4 2024), Zscaler reported revenue of $593 million, representing a 30% year-over-year growth. The increase in revenue was primarily driven by an increase in users and sales of additional subscriptions to existing customers, which contributed $91.40 million in additional revenue. The remainder of the increase was primarily attributable to the addition of new customers, as Zscaler increased its customer base by 14% from Q4 2023 to Q4 2024.

Zscaler's financial strength is further bolstered by its robust cash position, with over $2.4 billion in cash, cash equivalents, and short-term investments as of the end of the most recent fiscal year. This financial flexibility allows the company to invest in R&D, pursue strategic acquisitions, and maintain its competitive edge in the rapidly evolving cybersecurity landscape.

Profitability and Cash Flow

While Zscaler has demonstrated strong revenue growth, the company reported a net loss of $57.71 million for the fiscal year 2024. However, its cash flow metrics paint a more positive picture. Operating cash flow (OCF) for the year stood at $779.85 million, while free cash flow (FCF) reached $584.95 million, demonstrating the company's ability to generate significant cash from its operations.

In the most recent quarter (Q4 2024), Zscaler reported a net loss of $14.88 million. However, the company generated strong cash flows, with OCF of $252.80 million and FCF of $185.56 million. These robust cash flow figures underscore Zscaler's ability to fund its operations and investments while maintaining financial flexibility.

Liquidity and Financial Position

Zscaler maintains a solid financial position, with a debt-to-equity ratio of 0.98 (total debt of $1.24 billion / stockholders' equity of $1.27 billion). The company's liquidity remains strong, with $1.42 billion in cash and cash equivalents as of the end of the most recent fiscal year.

The company's current ratio stands at 1.04 (current assets of $3.40 billion / current liabilities of $3.11 billion), indicating that Zscaler has sufficient short-term assets to cover its short-term liabilities. The quick ratio, which excludes inventory from current assets, is also 1.04, further emphasizing the company's strong liquidity position.

Acquisition and Innovation

Zscaler's growth strategy has been marked by strategic acquisitions that have expanded its capabilities and solidified its position as a leading cloud security provider. In 2024, the company acquired Airgap Networks and Avalor Technologies, strengthening its Zero Trust security offerings for branch and IoT/OT environments, as well as its vulnerability management capabilities.

The integration of these acquired technologies has enabled Zscaler to offer a more comprehensive and seamless security solution, addressing the evolving needs of its customers as they navigate the complexities of modern IT infrastructure. Moreover, the company's continued investment in R&D has led to the development of innovative product features, such as its Gen AI Security solution, which helps organizations securely harness the power of generative AI without compromising data protection.

Zscaler's commitment to innovation and its ability to anticipate and address the changing security landscape have been instrumental in its success. As the threat of cyber attacks continues to escalate, with ransomware and state-sponsored activities on the rise, Zscaler's cloud-native, proxy-based architecture has proven to be a highly effective defense against these sophisticated threats.

Navigating Challenges and Building Resilience

While Zscaler has enjoyed remarkable success, the company has not been immune to the challenges posed by the broader economic environment. The recent macroeconomic pressures, including the impact of inflation and geopolitical tensions, have resulted in increased scrutiny from customers on purchasing decisions, particularly for larger transactions.

However, Zscaler has demonstrated its resilience by adapting its go-to-market strategy and strengthening its sales organization. The company has invested in building deeper relationships with its existing customer base, leveraging its land-and-expand model to drive increased adoption of its expanding platform. Additionally, Zscaler has made strategic investments in its global system integrator (GSI) channel, positioning its solutions as integral components of enterprise-wide digital transformation initiatives.

These proactive measures have enabled Zscaler to navigate the current economic landscape while maintaining its strong financial performance. In the most recent quarter, the company reported a 30% year-over-year increase in revenue, underscoring its ability to deliver consistent growth even in the face of headwinds.

Outlook and Future Potential

Looking ahead, Zscaler is well-positioned to capitalize on the growing demand for cloud-based security solutions. As organizations continue to embrace digital transformation and navigate the increasing complexity of hybrid work environments, the need for robust, scalable, and reliable security platforms like Zscaler's Zero Trust Exchange becomes increasingly paramount.

The company's strategic focus on emerging product categories, such as Zero Trust for branch and cloud, as well as its expanding AI and data protection capabilities, positions it for continued growth and market share expansion. Zscaler's stated goal of reaching $3 billion in annual recurring revenue (ARR) by fiscal year 2025 further reinforces its ambitious outlook and confidence in its ability to execute on its long-term growth strategy.

- Revenue of $604-$606 million, representing 22% year-over-year growth. - Gross margin of 80%. - Operating profit of $114-$116 million. - EPS of $0.62-$0.63.

The company also expects calculated billings for fiscal year 2025 to be in the range of $3.11-$3.135 billion, representing 19-20% year-over-year growth. Zscaler anticipates an acceleration in the second half of the fiscal year, driven by improved sales productivity, a strong pipeline, and higher contracted non-cancelable billings from prior years.

Despite the recent macroeconomic challenges, Zscaler's strong financial position, innovative product portfolio, and deep customer relationships suggest that the company is well-equipped to navigate the evolving cybersecurity landscape and capitalize on the substantial market opportunity ahead.

Risks and Considerations

As with any investment, Zscaler is not without its risks. The company operates in a highly competitive and rapidly changing industry, where it faces intense competition from both established security vendors and emerging cloud-native players. Zscaler's ability to maintain its technological edge and continue innovating at a pace that meets the demands of its customers will be critical to its long-term success.

Additionally, Zscaler's reliance on a relatively small number of large customers, as well as its exposure to global economic conditions, could present potential headwinds. The company's ability to effectively manage its sales and marketing efforts, while navigating a challenging macroeconomic environment, will be a key factor in its future performance.

Investors should also be mindful of the company's ongoing legal and regulatory compliance requirements, which could introduce additional costs and operational complexities as Zscaler continues to expand its global footprint.

Conclusion

Zscaler's journey has been one of continuous innovation, strategic execution, and unwavering commitment to securing the digital future of its customers. As the world becomes increasingly reliant on cloud-based services and remote work becomes the norm, the demand for Zscaler's comprehensive security solutions is poised to grow exponentially.
