In today’s digital landscape, businesses face a constant battle between website performance and cybersecurity threats. Every second of downtime can cost thousands of dollars, and a single breach can damage years of reputation. This is where Incapsula—now part of Imperva—enters the conversation. Known for combining a powerful Web Application Firewall (WAF) with a high-performance Content Delivery Network (CDN), Incapsula has been a trusted solution for enterprises, e-commerce platforms, and financial institutions.

In this detailed Incapsula review, we’ll break down its features, performance, security effectiveness, pricing, and how it stacks up against competitors.

Why Website Security and Performance Matter

Websites today aren’t just digital brochures—they are mission-critical platforms for transactions, data exchange, and customer engagement. A poorly performing site leads to lost conversions, while an unprotected one is an open door for hackers.

Industry reports show that 60% of small businesses close within 6 months of a cyberattack, and enterprises risk millions in regulatory fines if breaches occur. That’s why choosing the right CDN and WAF provider is no longer optional but essential.

What Is Incapsula (Imperva Incapsula)?

Incapsula, originally a standalone company, was acquired by Imperva, a global cybersecurity leader. Today, it’s widely referred to as Imperva Incapsula, offering a blend of cloud-based security and performance acceleration tools.

The platform protects websites and applications from:

  • DDoS attacks

  • SQL injections and XSS exploits

  • Zero-day vulnerabilities

  • Malicious bots and scraping tools

At the same time, it enhances speed through caching, load balancing, and a globally distributed CDN network.
