Summary
- Security Portfolio Outpaces Platform Peers: Security revenue mix expanded, signaling traction in cross-sell and product innovation.

Performance Analysis
Fastly delivered 12% year-over-year revenue growth in Q2, outpacing the prior quarter’s 8% rate and exceeding guidance. The standout was security, which climbed 15% year-over-year and now represents 20% of total revenue—a record high for the company. Network services, the core CDN (content delivery network, a platform for fast and secure digital delivery) business, grew 10% year-over-year, while compute products surged 60%, albeit from a smaller base.
Gross margin improved to 59%, up 170 basis points sequentially, thanks to network efficiency gains, technology enhancements, and favorable pricing. Operating loss narrowed to $4.6 million, reflecting a notable shift toward operating leverage as operating expenses rose just 2% against 12% revenue growth. Cash flow from operations reached $26 million, or 17% of revenue, and free cash flow swung positive, a $29.5 million improvement over the prior year. RPO (remaining performance obligations, contracted future revenue yet to be recognized) soared 41% to a record $315 million, underpinned by higher customer commitments and package adoption.
- Security Share Expansion: Security now accounts for one-fifth of revenue, with new products driving customer adoption and competitive takeouts.
- Customer Diversification Accelerates: Revenue outside the top 10 customers grew 17% year-over-year, marking the fifth consecutive quarter outpacing overall growth.
- Margin Gains and Cash Discipline: Improved network utilization, pricing discipline, and cost control drove margin and cash flow upside.
Fastly’s customer base reached 3,097, with enterprise accounts up by 27 sequentially. Trailing 12-month net retention improved to 104%, reflecting renewed momentum and commitment from larger customers. Revenue concentration declined, with the top 10 customers representing 31% of sales, down from 33% last quarter, signaling reduced risk and greater revenue stability.
Executive Commentary
"Going forward, I'm excited to share my vision for Fastly with a keen focus on accelerating our growth rate and driving to profitability in the near term.

Kip Compton, CEO
"We exited the second quarter with a record RPO of $315 million, growing 41% year over year. This growth reflects progress in our efforts to increase the number of customers with revenue commitments and to drive higher commitment levels with our largest customers, coupled with an increasing share of predictable revenue packages as a proportion of our revenue."

Strategic Positioning
1. Security and Platform Expansion
Security solutions are now central to Fastly’s value proposition, with new launches in DDoS attack insights and bot mitigation enabling both competitive displacement and deeper customer integration. The company’s NextGen WAF (web application firewall, a security filter for web traffic) and adaptive security features are opening doors to new verticals, especially in financial services, healthcare, and omnichannel retail.
2. Go-to-Market Realignment
Leadership has consolidated revenue and marketing functions, with Scott Lovett promoted to President of Go-to-Market to unify sales, marketing, and customer success. The sales organization is now segmented to prioritize high-performance customers and incentivize cross-sell, with nearly half of customers using two or more products and those customers generating over 75% of revenue.
3. Revenue Diversification and International Focus
Fastly is targeting Fortune 1000 and digitally native organizations, aiming to capitalize on incumbent inertia and expand internationally. New leadership in APJ (Asia-Pacific and Japan) and Southern Europe positions the company for incremental growth, with a focus on simplicity in pricing and onboarding to reduce friction and accelerate adoption.
4. Margin and Cost Structure Optimization
Network efficiency and disciplined pricing are driving gross margin gains, while operating expenses are being tightly managed. The company anticipates further margin stability as international traffic grows and price declines moderate, with capital expenditures expected to trend down over the medium term.
5. Leadership Transition and Strategic Continuity
CEO Kip Compton’s elevation from Chief Product Officer brings continuity in product strategy and execution, while the incoming CFO brings deep SaaS and platform experience. The leadership bench is positioned to accelerate both growth and profitability, with ongoing evolution expected as the business scales.
Key Considerations
Fastly’s Q2 marks an inflection point, with management signaling a new chapter focused on execution, profitability, and scaling security-led growth. The company is leveraging recent industry consolidation and platform innovation to win new customers and deepen wallet share, while also addressing prior volatility in customer concentration and retention.
Key Considerations:
- Security Product Momentum: New feature launches and platform integration are enabling competitive takeouts and higher customer stickiness.
- Customer Base Diversification: Revenue mix is less reliant on top customers, reducing risk and improving revenue predictability.
- Go-to-Market Transformation: Unified sales and marketing is driving higher productivity, cross-sell, and up-sell rates.
- Operational Discipline: Tight cost control and cash management are accelerating the path to profitability and positive free cash flow.
- International Opportunity: Underexposed international footprint is a lever for incremental growth in 2026 and beyond.
Risks
Customer concentration remains a latent risk, though declining, with top 10 customers still accounting for nearly a third of revenue. Industry price pressure could reemerge, especially if competitive dynamics shift, and reliance on continued cross-sell and up-sell momentum is critical for sustaining growth rates. Execution risk is elevated during leadership transition, and international expansion will require investment and local adaptation. Regulatory uncertainty around customers like TikTok, though now a smaller revenue share, could still impact results if policies shift abruptly.
Forward Outlook
For Q3 2025, Fastly guided to:
- Revenue of $151 to $153 million, representing 10% annual growth at midpoint
- Gross margin of 59.5%, plus or minus 50 basis points
- Non-GAAP operating loss of $1 million to profit of $3 million
For full-year 2025, management raised guidance:
- Revenue to $594 to $602 million (10% annual growth at midpoint)
- Operating loss narrowed to $9 million to $3 million
- Free cash flow now expected between break-even and positive $10 million
Management highlighted ongoing network efficiency, pricing discipline, and cost controls as drivers for margin and cash flow improvements, and signaled further product releases and international expansion in 2026.
- Continued focus on high-commitment enterprise customers
- Product innovation in security and compute to drive platform adoption
Takeaways
Fastly’s Q2 results underscore an accelerating platform transition, with security and multi-product adoption driving both growth and margin leverage. The leadership team is signaling a more aggressive stance on profitability and international expansion, while maintaining a strong focus on customer-centric product development.
- Security and Platform Gains: Security revenue mix and cross-sell rates validate the platform strategy, underpinning future growth and stickiness.
- Operational Leverage Emerges: Margin and free cash flow improvement demonstrate cost discipline and a credible path to profitability.
- Execution and Innovation Watch: Investors should monitor go-to-market productivity, international traction, and continued product release cadence as key drivers into 2026.
Conclusion
Fastly’s Q2 marked a clear pivot toward sustainable growth, with security and platform adoption fueling both top-line and margin expansion. Leadership realignment and a more unified go-to-market approach position the company for durable gains, though execution and competitive risks remain. The next quarters will test Fastly’s ability to translate backlog and product momentum into lasting operating profit and differentiated market share.
Industry Read-Through
Fastly’s results highlight a broader shift in the edge cloud and CDN space toward security-led growth and platform consolidation. Incumbents slow to innovate are ceding ground to players that can deliver integrated security, analytics, and compute at the edge. Customer demand for multi-product, high-commitment relationships is intensifying, favoring vendors that can simplify onboarding and pricing. Industry consolidation and pricing discipline are stabilizing margins, but the pace of product innovation and international expansion will increasingly separate winners from laggards. Other CDN and edge compute providers should note the growing importance of security, platform breadth, and go-to-market integration as key competitive levers.
