We’re excited to announce the launch of Upload Scan and Control, an essential new feature for Imperva Cloud WAF. This add-on tackles one of the most critical vulnerabilities facing web applications today—insecure file uploads—offering protection with scalability, simplicity, and enterprise-grade control.

Why Secure File Upload Protection Is Critical for Modern Web Applications

File upload functionality is now a staple in web applications; from job portals accepting résumés to customer support platforms collecting documents.

Unfortunately, attackers exploit this functionality to inject malware, ransomware, and other malicious payloads into systems. This also can become the main source for remote code executions.

With Upload Scan and Control integrated into your Web Application Firewall (WAF), you’ll soon be able to enforce file size and type restrictions, blocking unauthorized or suspicious files before they enter your environment, ensuring your upload capabilities remain safe and compliant.

According to the OWASP Top Ten, insecure file uploads remain one of the most exploited web application vulnerabilities worldwide.

The Growing Risk of Malicious File Uploads

Across the Cloud WAF user base, we process over 20 million file uploads daily, with more than 800 customers across industries like finance, healthcare, retail, and government.

Cyber attackers are becoming more sophisticated and often target file uploads as an initial entry point. The earlier you can block malicious content, before it hits an endpoint or server, the greater your chances of preventing a breach entirely.

Why Network-Layer File Upload Security Beats Endpoint-Only Protection

Endpoint antivirus and EDR tools play a critical role in detection, but they typically act after malicious files land on your system. At this stage, it may already be too late. Investigations take longer, the damage may already be done, and attackers may have gained a foothold.

Upload Scan and Control stops threats at the edge, before files are saved or executed, enabling true prevention over delayed remediation before they even reach your network layer.

Advantages of Imperva Upload Scan and Control for Cloud WAF

Our new feature delivers several enterprise-grade benefits:

1. Full visibility across all upload points: Identify which applications allow file uploads and monitor activity from a single dashboard.
2. Instant, one-click activation: Protect all current and future apps automatically, eliminating developer integration work.
3. Scalable security for large enterprises: No additional requirements for app owners or developers to introduce additional integrations significantly reducing operational overheads.

Peace of Mind for Security Leaders and Compliance Teams

With Upload Scan and Control, enterprises can:

• Block threats at the edge before they reach your network.
• Trace file origins and identify the responsible user or IP.
• Maintain audit-ready compliance records (such as GDPR, CCPA, and HIPAA) without adding complexity to existing security stacks.

As cloud-native adoption accelerates and threat actors adapt, features like this are becoming essential to maintaining a secure, compliant perimeter.
