Feature module	Description	On-cloud WAF Pro	On-cloud WAF Business	On-cloud WAF Enterprise	On-cloud WAF Exclusive (unavailable for purchase)	Hybrid Cloud WAF Exclusive
Website access
HTTPS protection	Allows you to configure HTTPS protection for websites with a few clicks.
Asset discovery	Discovers and manages website assets. You can add assets to WAF with a few clicks.
Transparent proxy mode	Redirects the traffic that is sent to origin servers to WAF. The origin servers can be Elastic Compute Service (ECS) instances or servers that are added to Server Load Balancer (SLB) instances.
HTTP/2 protection	Protects websites that use HTTP/2.
Custom port protection	Protects services that use custom ports apart from standard ports. The standard ports include 80, 8080, 443, and 8443.
IPv6 traffic protection	Detects and protects IPv6 traffic.
Exclusive cluster	Allows you to modify service access configurations and protection capabilities based on your business requirements.
On-premises protection cluster deployment	Deploys WAF protection clusters in data centers to protect web traffic that is not sent to Alibaba Cloud.
Intelligent load balancing	Connects to multiple SLB service nodes to perform automatic disaster recovery and optimal routing at low latency.
Exclusive IP addresses	Provides exclusive IP addresses to protect specific domain names.
Website protection
Protection rules engine	Protects your services against common web attacks such as SQL injection and cross-site scripting (XSS) attacks.
	Enables automatic updates of protection rules that are configured for web zero-day vulnerabilities.
Website tamper-proofing	Locks web pages to prevent content tampering.
Data leakage prevention	Prevents sensitive data such as ID card numbers, mobile phone numbers, and bank card numbers from being leaked.
HTTP flood protection	Protects your services against common HTTP flood attacks in Prevention or Prevention-emergency mode.
Account security	Detects dictionary attacks, brute-force attacks, spam user registrations, weak passwords, and SMS flood attacks on service endpoints such as registration endpoints and logon endpoints.
IP address blacklist	Blocks access requests that are sent from specific IP addresses or CIDR blocks.
	Blocks access requests that are sent from IP addresses in specific regions.
Scan protection	Blocks the IP addresses of scanners and the IP addresses from which high-frequency web attacks or path traversal attacks are initiated. This feature provides collaborative defense capabilities.
	Allows you to configure custom rules to block high-frequency web attacks and path traversal attacks.
Custom protection policy	Supports ACL-based access control by using basic fields such as IP, URL, Referer, User-Agent, and Params.
	Supports ACL-based access control by using advanced fields such as Cookie, Content-Type, Header, and Http-Method.
	Allows you to configure throttling policies based on IP addresses and sessions. You can add match conditions and configure throttling policies to modify HTTP flood protection rules.
	Allows you to configure throttling policies based on IP addresses, sessions, and custom fields.
Anti-DDoS	Defends against DDoS attacks of up to 5 Gbit/s free of charge.
Custom protection rule group	Allows you to configure custom protection rule groups.
Positive security model	Provides positive defense capabilities based on the deep learning operations that are performed on website traffic.
Data risk control	Protects critical website services against frauds. These services include registrations, logons, activities, and forums.
Allowed crawlers	Maintains a whitelist that consists of authorized search engines. The crawlers of these search engines are allowed to access specified domain names.
Bot threat intelligence	Provides information about suspicious IP addresses that are used by dialers, data centers, and malicious scanners. This feature also maintains an IP address library of malicious crawlers and prevents these crawlers from accessing all pages related to your domain name or specific directories.
App protection	Provides secure connections and anti-bot protection for native apps. This feature can identify requests that contain invalid signatures and requests that are sent from proxy servers and emulators.
Security analysis and support
Alert setting	Allows you to configure event monitoring and alerting for WAF.
Log Service for WAF	Collects and stores all logs, enables near-real-time query and analysis, and provides online reports.
