Atlassian vs. Zscaler: Which Technology Stock Is a Better Buy for 2027?
Atlassian is growing fast and now turning a profit, but its stock fell on slower guidance. Zscaler is a major cloud security player that recently posted a small loss.
Investors are currently deciding between Atlassian and Zscaler for their 2027 portfolios. Atlassian specializes in team collaboration and workflow management, while Zscaler focuses on securing the digital perimeter with its zero-trust platform. Both companies are crucial components of the modern enterprise stack, but their market dynamics differ. Comparing their financial health and risk profiles may help determine which stock may be a better fit for individual investment goals.
Atlassian offers collaboration and work management tools, including Jira and Confluence. It serves over 350,000 customers and is utilized by more than 85% of the Fortune 500. The company relies on a product-led model, with users starting with self-service tools before deepening relationships through its marketplace of over 6,000 third-party apps.
In FY 2026, Atlassian's revenue grew by approximately 26%, reaching nearly $6.6 billion, despite reporting a net loss of around $53.8 million. Its debt-to-equity ratio stands at nearly 1.2x, and its current ratio is approximately 0.8x, indicating relatively low liquidity. Stock-based compensation accounted for roughly 118.7% of operating cash flow, which could inflate reported cash generation.
Zscaler, on the other hand, provides cloud-delivered security services through its zero-trust platform. It serves approximately 11,000 customers, including 50% of the Fortune 500 and 40% of the Forbes Global 2000. The company relies heavily on channel partners, having recently partnered with IBM and Red Hat to provide secure private application access.
In FY 2026, Zscaler's revenue grew by nearly 25.4%, reaching close to $3.4 billion, with a net loss of around $63.2 million and a net margin of roughly -1.9%. Its debt-to-equity ratio is roughly 0.7x, and its current ratio is approximately 1.7x, indicating a more robust liquidity position. The company's reported free cash flow reached nearly $852.4 million, but stock-based compensation accounted for roughly 72.8% of operating cash flow, which could inflate reported cash generation.
Both companies face intense competition in their respective markets. Atlassian must shift its customer base from legacy products to cloud offerings, which could pressure revenue growth rates. Zscaler operates in a highly competitive market where it competes with legacy security vendors and large cloud providers like Microsoft and Amazon.
Any security breach in its cloud platform could severely impact its reputation and client trust. Additionally, the companies have different valuation metrics. Atlassian has a lower P/S ratio and Forward P/E than Zscaler, indicating it may be a cheaper option. However, Atlassian has shown a significant improvement in revenue growth and profitability, which may make it an attractive choice for long-term investors.
Despite a temporary drop in stock price after management's slower growth guidance, Atlassian expects strong cloud growth in 2027. In contrast, Zscaler has also shown solid growth potential but faces heavier spending on infrastructure, which has affected its cash flow. Given the vote of confidence from its customers, who are signing larger and longer commitments, Atlassian may be the better buy for 2027.
