Radware (RDWR) Q4 2025: Cloud ARR Jumps 23% as API and AI Security Fuel Expansion
Radware capped 2025 with record cloud ARR growth, a robust deal pipeline, and accelerated innovation in API and agentic AI security. Operational leverage and targeted investments are reshaping its business mix, while leadership signals a multi-pronged strategy to capture expanding security demand into 2026.
Summary
- Cloud Security Acceleration: Cloud ARR momentum and new API/AI offerings are shifting Radware’s business mix.
- Operational Leverage Evident: Margin expansion and disciplined capital allocation reinforce balance sheet strength.
- Innovation Pipeline Expands: Full lifecycle API and agentic AI security position Radware for the next wave of enterprise demand.
Business Overview
Radware provides application and data center security solutions, with revenue from cloud-based security services, on-premises appliances, and related software subscriptions. Its major segments are cloud security, including DDoS (distributed denial of service) and API (application programming interface) protection, and hardware/software product lines such as DefenseProX, a next-generation threat mitigation platform. The company’s revenue model blends recurring ARR (annual recurring revenue) from subscriptions with perpetual and term-based hardware and software sales.
Performance Analysis
Radware delivered a strong close to 2025, with double-digit revenue growth and record results across key financial metrics. Cloud ARR surged 23% year-over-year to $95 million, outpacing total ARR growth and becoming a larger share of the business. This acceleration was driven by robust demand in cloud security and a major refresh cycle for DefenseProX, which saw double-digit growth in both new and existing customer wins.
Regional performance was mixed: EMEA posted standout growth, with fourth-quarter revenue up 38% year-over-year and now representing 40% of total revenue. The Americas region declined 4% in Q4 but grew 6% for the full year, while APAC revenue dipped slightly in Q4 but rose 5% annually. Margins expanded materially, with operating margin up 240 basis points in Q4 and adjusted EBITDA margin reaching 21.1% excluding discontinued operations, reflecting operational leverage and favorable business mix.
- Cloud Mix Shift: Cloud ARR now comprises a growing portion of total ARR, supporting recurring revenue visibility.
- DefenseProX Refresh: Major refresh cycle is less than halfway complete, suggesting continued tailwinds for product and subscription revenue.
- Deal Visibility: RPO (remaining performance obligations) climbed to $400 million, up 13% YoY, signaling strong future revenue conversion.
Cash flow from operations remained solid, and a $461 million liquidity position gives Radware flexibility for continued investment in cloud infrastructure and targeted M&A. The company executed a $10.5 million share repurchase in Q4, underscoring disciplined capital allocation.

Strategic Positioning
1. Cloud Security as Growth Engine
Cloud security is now Radware’s primary growth lever, with cloud ARR growth accelerating throughout the year. The company’s ability to secure large, multi-year cloud deals—such as a seven-figure win with a European financial group—demonstrates traction with both new and existing customers. Cloud ARR’s 23% growth rate signals structural demand for DDoS, web, and API protection as enterprises modernize their architectures.
2. API Security Platform Expansion
API security is emerging as a third growth wave, following DDoS and application security. The acquisition of Pint Security, an API testing startup, enables Radware to deliver a full lifecycle solution—spanning discovery, posture management, and runtime protection. This positions the company to capitalize as enterprises seek comprehensive coverage for business logic and shadow API risks.
3. Agentic AI Security Opportunity
Radware’s launch of agentic AI protection targets a new frontier as enterprises deploy AI agents with access to sensitive data and systems. The offering leverages behavioral algorithms for real-time detection and intent analysis, aiming to protect against prompt-based attacks and unauthorized access. Management frames this as a significant TAM (total addressable market) expansion, with a dedicated go-to-market overlay group advancing early adoption.
4. Go-to-Market and Regional Investment
Radware is intensifying investment in North America, adding sales personnel and new routes to market to reverse recent softness and capture a larger share of cloud and hybrid security demand. EMEA’s outsized growth reflects successful execution, while APAC remains steady. The company’s pipeline is robust across both new logos and expansion deals, with large wins in government and SaaS verticals.
5. Operational Leverage and Capital Allocation
Margin expansion and disciplined spending are driving improved profitability. The company is scaling cloud infrastructure and innovation spend, but remains focused on cost discipline. A strong cash position supports organic growth, platform innovation, and selective M&A, while share repurchases reinforce shareholder return priorities.
Key Considerations
Radware’s Q4 results reflect a business in transition, with cloud and subscription revenues reshaping the financial profile and innovation broadening the platform opportunity.
Key Considerations:
- Cloud ARR Mix Shift: Cloud security is becoming the dominant driver of ARR growth and margin structure.
- API and AI Security Pipeline: Full lifecycle API and new agentic AI solutions create new vectors for growth and cross-sell.
- DefenseProX Refresh Cycle: Ongoing product refresh is less than halfway complete, providing multi-quarter tailwinds.
- Regional Execution Required: North America remains a key focus for investment and turnaround, with leadership signaling confidence in a rebound.
- Capital Flexibility: Strong liquidity and cash flow support continued R&D, go-to-market expansion, and opportunistic M&A.
Risks
Radware faces execution risk in scaling its agentic AI and API security offerings, especially as enterprise adoption is still early and buyer responsibilities remain fluid. Regional performance is uneven, with the Americas requiring continued investment to regain momentum. Competitive intensity in cloud security and rapid evolution of attack vectors could pressure pricing or require accelerated R&D spend. FX volatility and macroeconomic uncertainty, especially in EMEA and APAC, may also impact revenue conversion.
Forward Outlook
For Q1 2026, Radware guided to:
- Total revenue of $78 to $79 million
- Non-GAAP operating expenses of $54 to $55 million, reflecting increased investment and FX headwinds
- Non-GAAP diluted net earnings per share of $0.28 to $0.29
For full-year 2026, management expects:
- RPO (remaining performance obligations) to grow in line with revenue, with upside potential if booking strength persists
Management highlighted:
- Backlog strength and robust Q4 bookings underpinning revenue visibility into 2026
- Continued investment in innovation, especially in AI and cloud, as key to sustaining growth
Takeaways
Radware’s cloud-first pivot is gaining traction, with API and AI security opening new growth vectors and recurring revenue mix supporting margin expansion.
- Cloud and Subscription Momentum: Cloud ARR and DefenseProX refresh cycles are the primary engines for sustainable top-line and margin growth.
- Innovation-Driven Differentiation: Full lifecycle API and agentic AI security offerings position Radware as a best-of-breed provider in a rapidly evolving threat landscape.
- Execution Watchpoint: Investors should monitor North America’s rebound and the pace of adoption for new AI security products as leading indicators for 2026 trajectory.
Conclusion
Radware exits 2025 with record results, a robust innovation pipeline, and a clear shift toward cloud and recurring revenue. The company’s ability to scale new security offerings and drive regional execution will determine the durability of its growth and margin expansion in 2026 and beyond.
Industry Read-Through
Radware’s results reinforce the structural shift toward cloud-native security, with API and agentic AI protection emerging as must-have capabilities for enterprise buyers. The accelerating refresh cycles and multi-year cloud deals suggest that hybrid and cloud-first security models are gaining share over legacy on-premise approaches. Competitors in the security space will need to invest in AI-driven defense and full lifecycle API security to remain relevant, while channel partners and integrators may see increased demand for bundled, subscription-based offerings. The early-stage adoption of agentic AI security signals a new battleground for innovation and differentiation across the cybersecurity sector.
