Fastly's Security Revenues Climb 47%: Is Diversification Paying Off?
Read MoreHide Full Article
Key Takeaways
Fastly's security revenues rose 47% YoY to $38.8M, hitting 22% of total revenues in Q1.
Next-Gen WAF led, but DDoS Protection, Bot Management and API Discovery gained traction with new customers.
Seven-figure security deals and smaller wins supported growth as AI bot traffic and shadow API risks rose.
Fastly, Inc. (FSLY - Free Report) delivered a strong first-quarter 2026 performance in its security business, with security revenues increasing 47% year over year to $38.8 million. Security accounted for 22% of total revenues in the quarter, reaching record levels for the company. The segment also grew 9% sequentially, marking the fourth straight quarter of accelerating security revenue growth.
Fastly’s security momentum is becoming stronger. Its Next-Gen WAF remained a core driver, but newer products also gained traction. These include DDoS Protection, Bot Management, and API Discovery and Inventory. Among instances of security products sold to new customers in the quarter, almost half came from these newer offerings. This indicates that Fastly’s security portfolio is expanding beyond one flagship product and gaining relevance across a wider set of customer needs.
Customer activity also supported the security growth story. Fastly closed multiple seven-figure deals that included security, while smaller wins also contributed. This suggests the quarter’s growth was not associated with just one isolated transaction.
AI-related traffic and security risks are also adding to the relevance of Fastly’s tools. ContentGuard was added by a long-standing media customer facing daily malicious AI bot traffic, while API security tools were positioned to help address shadow API risks as AI speeds up code delivery.
Fastly’s security business is becoming a more meaningful part of the company’s revenue mix. With stronger adoption across both established and newer security products, the segment’s momentum reflects improving product depth, broader customer engagement and a clearer role for security within Fastly’s platform strategy.
