Radware (RDWR) Q2 2025: Cloud ARR Accelerates to 21% as AI Security Differentiation Widens
Radware delivered its fourth straight quarter of double-digit revenue growth as cloud ARR acceleration and AI-driven security innovation are reshaping its business mix and market positioning. Management’s focus on AI-powered automation and channel expansion is translating into higher win rates, while a full transition to next-gen DefensePro X hardware sets up a multi-year refresh cycle. With cloud and AI investments ramping, the company’s margin leverage and competitive moat will be tested as the security landscape evolves rapidly.
Summary
- Cloud Security Outpaces Legacy: Cloud ARR growth reached 21% YoY, now driving most new bookings and customer wins.
- AI-Driven Differentiation Emerges: Proprietary AI frameworks and agentic automation are shortening response times and winning competitive takeouts.
- Sales Realignment Gains Traction: North American pipeline and early deal momentum signal successful go-to-market changes.
Performance Analysis
Radware posted a 10% YoY revenue increase to $74 million, marking its fourth consecutive quarter of double-digit top-line growth. The company’s cloud ARR, annual recurring revenue from cloud subscriptions, accelerated to 21% YoY, reaching $85 million and surpassing the prior 20% target, now representing a growing share of total ARR at $235 million. Regionally, EMEA led with 22% revenue growth, APAC surged 30%, and the Americas remained stable but showed improving pipeline trends.
Profitability scaled sharply: non-GAAP EPS rose 39% YoY, operating income expanded over 50%, and adjusted EBITDA margin improved, especially when excluding the legacy hox business. Gross margin stayed robust, while operating leverage enabled increased investment in sales and R&D, particularly in cloud and AI. Cash flow from operations was solid at $14.5 million, though down from the prior year due to elevated investment. The balance sheet remains strong with $459 million in liquidity, supporting ongoing innovation and go-to-market expansion.
- Cloud Security as Growth Engine: Cloud now comprises 84% of total revenue, up from 82% a year ago, reflecting the business model’s shift away from legacy hardware.
- AI Automation Compresses Response Times: SOCX expert, Radware’s AI-powered security operations agent, is reducing mean time to resolve attacks from hours to minutes, a key factor in recent seven-digit wins.
- Sales Model Realignment: The bifurcation into “hunter” (new logo) and “farmer” (existing account) teams is already driving higher coverage, more upgrades, and cross-sell activity.
Underlying these results is a disciplined capital allocation that balances aggressive cloud and AI investment with operational efficiency, positioning Radware for sustainable multi-year growth if execution holds.
Executive Commentary
"Cloud security continues to be our primary growth engine. In the second quarter, we accelerated cloud ARR growth from 19% to 21% year-over-year, reaching $85 million. With that, we surpassed our short-term target of 20% year-over-year growth rate."
Roy Zisapel, President and Chief Executive Officer
"Our recurring business model continues to demonstrate strong leverage, enabling us to expand those growth initiatives. Excluding the hox business, adjusted EBITDA was $14.1 million, representing a 19% EBITDA margin, up from $11 million and 14.4% EBITDA margin in Q2 2024, reflecting improved operational efficiency and scaling our core business."

Strategic Positioning
1. Cloud Security and ARR Momentum
Cloud ARR is now the primary performance lever, with growth accelerating to 21% YoY and the business surpassing its previous 20% growth target. Management is targeting 25% as the next milestone, signaling ongoing prioritization of recurring, high-margin cloud contracts over legacy hardware.
2. AI-Driven Product Differentiation
Radware’s Epic AI framework and SOCX expert are embedding AI across detection, mitigation, and response, automating real-time threat analysis and response. These capabilities are now winning seven-digit deals and displacing competitors, as customers seek faster, more adaptive protection against AI-powered attacks. The company’s ability to automatically map business logic and generate protection rules is a key competitive differentiator in API and application security.
3. Channel and Go-to-Market Expansion
Channel partnerships and a revamped sales model are unlocking new customer segments and geographies. The North American sales force expansion and split into acquisition (“hunter”) and account management (“farmer”) teams is already yielding a stronger pipeline and higher win rates. Major wins with data center providers, governments, and financial institutions underscore the effectiveness of this approach.
4. DefensePro X Refresh Cycle
The complete transition to DefensePro X hardware, Radware’s next-gen DDoS mitigation platform, means all new on-premise sales now pull through higher-margin subscriptions and set up a multi-year refresh opportunity across the installed base. Customer feedback and competitive displacements indicate strong market acceptance and a tailwind for hardware-driven recurring revenue.
5. MSSP and Carrier Channel Leverage
Radware is seeing early signs of opportunity with MSSPs, managed security service providers, as compliance and AI-driven threats force carriers to upgrade their security portfolios. The company’s cloud platform is well-positioned to help partners address evolving regulatory and customer requirements, opening a potentially scalable indirect channel.
Key Considerations
Radware’s Q2 was marked by a decisive pivot toward cloud and AI, but the landscape ahead is highly dynamic, with execution and competitive differentiation remaining key watchpoints.
Key Considerations:
- Cloud ARR as Core Value Driver: Sustained cloud ARR acceleration is now the clearest indicator of Radware’s long-term growth and margin profile.
- AI as Both Threat and Enabler: As AI increases attack sophistication, Radware’s investment in AI-powered defense is both a moat and a necessity for future relevance.
- Sales Model Execution Risk: The realignment of sales resources is showing early promise, but will require continued investment and management focus to fully realize pipeline potential, especially in North America.
- Hardware-to-Subscription Transition: The DefensePro X refresh cycle offers a unique window to convert hardware customers to higher-value, recurring cloud and hybrid subscriptions.
- Competitive and Regulatory Uncertainty: While Radware’s win rates are rising, the security market is prone to rapid innovation cycles and new entrants, particularly in AI-specific domains.
Risks
Radware faces a fast-evolving threat landscape, with AI both heightening attack complexity and lowering barriers for new competitors. Prolonged enterprise sales cycles and budget scrutiny, especially in large North American accounts, could temper near-term growth. Execution risk remains around scaling channel partnerships and fully realizing the DefensePro X refresh opportunity, while regulatory shifts may alter MSSP and carrier demand patterns.
Forward Outlook
For Q3 2025, Radware guided to:
- Total revenue of $74.5 to $75.5 million
- Non-GAAP operating expenses of $51.5 to $52.5 million
- Non-GAAP diluted net EPS of $0.26 to $0.27
For full-year 2025, management remains focused on:
- Accelerating cloud ARR growth beyond the current 21% rate
- Continued investment in cloud and AI innovation
Management highlighted several factors that will drive results:
- Ongoing channel and partner ecosystem expansion to scale efficiently
- Further investment in North American sales capacity and leadership
Takeaways
Radware’s Q2 results underscore a business in transition, with cloud and AI at the center of its future. The company is executing well on its strategic pivots, but must continue to deliver against rising expectations in a highly competitive sector.
- Cloud and AI Now Anchor Growth: Cloud ARR and AI-driven innovation are translating into higher win rates and a more recurring revenue base, but require sustained investment and operational discipline.
