Business Overview
Fastly operates a global edge cloud platform, enabling businesses to deliver, secure, and govern digital content and applications at scale. The company generates revenue primarily through consumption-based pricing across three major segments: network services (content delivery and acceleration), security (NG WAF, DDoS protection, bot management), and compute (edge computing and AI-driven workloads). Fastly’s unified platform approach allows customers to consolidate infrastructure, enhance performance, and manage security in real time.
Performance Analysis
Fastly delivered a record quarter, with revenue up 23% year-over-year, driven by broad-based adoption across its platform. Security revenue led the way, rising 43% and now comprising 23% of total revenue, up from 20% a year ago. Compute, though still a smaller contributor, grew 69% and is gaining traction as AI workloads proliferate. Network services, the company’s legacy core, posted 17% growth and remains 73% of the revenue mix.
Gross margin reached a record 65.8%, reflecting both operating leverage and the shift toward higher-value products. Top 10 customers accounted for 37% of revenue, with their spend up 48% year-over-year, while non-top 10 customer growth decelerated to 12%. Episodic events such as major sporting broadcasts provided a temporary boost, but underlying platform expansion and cross-sell drove sustained net retention rate improvement to 117%. Fastly’s sixth consecutive quarter of positive free cash flow and disciplined CapEx management reinforce the durability of its model.
- Security Mix Shift: Security’s rising share of revenue signals a strategic pivot toward higher-margin, recurring business.
- Top Customer Concentration: Growth is increasingly weighted to large accounts, underscoring both platform success and future diversification risk.
- AI and Agentic Traffic Impact: Machine-generated requests are growing 6.5x faster than human traffic, reshaping product adoption and monetization patterns.
While platform consolidation and AI-fueled demand are driving the current upcycle, the company’s ability to broaden new logo growth and sustain NRR momentum will be critical for long-term upside.

Strategic Positioning
1. Platform Consolidation as a Growth Engine
Fastly’s unified platform approach is driving deeper customer integration, as evidenced by rising net retention and multi-product adoption. Customers are increasingly standardizing their infrastructure on Fastly, consolidating edge delivery, security, and compute to reduce complexity and risk. This strategy is increasing wallet share and reducing churn, with notable wins in fintech, education, and retail sectors.
2. Security and Compute as Value Drivers
The security portfolio’s 43% growth (led by NG WAF, DDoS, and bot management) underscores Fastly’s ability to monetize traffic complexity and threat proliferation. Compute, fueled by AI and agentic traffic, is emerging as an expansion lever, though still early in its revenue contribution. The cross-sell motion—landing security solutions in existing network services accounts—remains the primary driver of net retention gains.
3. AI and Agentic Traffic: Structural Demand Shift
AI-driven and machine-generated traffic is fundamentally altering Fastly’s demand equation. These workloads are more complex and require real-time decisioning at the edge, increasing demand for compute and advanced security. Fastly’s platform is well positioned to capture this shift, with machine traffic now growing at 6.5x the rate of human traffic and driving triple-digit growth in bot and DDoS solutions.
4. Operational Discipline and Efficiency
Disciplined cost control and capital allocation have produced record gross and operating margins. Fastly’s software-defined infrastructure and single-platform model enable higher utilization and lower incremental capital needs versus legacy competitors, supporting both growth and profitability targets.
5. Customer Concentration and Go-to-Market Evolution
While large accounts are fueling headline growth, management acknowledges the need to accelerate new logo acquisition and broaden the customer base. Ongoing go-to-market transformation, including APAC investments and marketing leadership changes, aims to rebalance growth and reduce future concentration risk.
Key Considerations
This quarter’s results highlight Fastly’s strategic inflection, but also surface critical areas for ongoing execution and risk management.
Key Considerations:
- Security Penetration Still Early: DDoS and bot management are in the “second innings,” leaving significant cross-sell runway within the existing base.
- AI Monetization Leverage: The rapid rise of agentic traffic is driving higher-value product adoption, but its long-term revenue mix impact remains unproven.
- Customer Mix Risk: Top 10 customer concentration increased, raising dependency risk, especially as episodic events fade and non-top 10 growth lags.
- Capital Allocation Discipline: Front-loaded CapEx in H1 2026 positions Fastly for growth, but moderation is expected in H2 as supply chain uncertainty eases.
Risks
Fastly faces notable risks from customer concentration, with top accounts driving a disproportionate share of growth. Seasonal and episodic events can mask underlying demand trends, while the shift to AI and agentic workloads introduces both opportunity and competitive threat as peers intensify infrastructure and feature investments. Price erosion in network services remains a structural headwind, mitigated only partially by higher-value product mix. Execution on new customer acquisition and sustaining net retention momentum will be key to de-risking the growth narrative.
Forward Outlook
For Q3 2026, Fastly guided to:
- Revenue of $184 million to $190 million (18% annual growth at midpoint)
- Gross margin of 65% plus or minus 50 basis points
- Non-GAAP operating profit of $20 million to $24 million (12% margin at midpoint)
For full-year 2026, management raised guidance:
- Revenue of $732 million to $746 million (18% annual growth at midpoint)
- Operating profit of $88 million to $96 million (12% margin at midpoint)
- Free cash flow of $40 million to $50 million
Management emphasized:
- Gross margin durability is underpinned by platform efficiency and product mix shift
- CapEx will moderate in H2 after being front-loaded to address supply chain constraints
- Go-to-market transformation and APAC expansion are expected to drive broader customer growth
Takeaways
Fastly’s Q2 results validate its platform consolidation strategy, with security and compute emerging as structural drivers of higher-margin, durable growth.
- Platform Expansion: Unified product adoption is deepening customer engagement and boosting net retention, but new logo growth and broader customer diversification must accelerate to sustain the trajectory.
