HTTP/2 protection	Protects websites that use HTTP/2.
Protection for non-standard ports	Protects services that use custom ports other than standard ports. The standard ports include port 80, port 8080, port 443, and port 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 address	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 XSS attacks.
Protection rules engine	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 leak 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.
IP address blacklist	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.
Scan protection	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. For information about the defense capabilities, see View the thresholds that trigger blackhole filtering in Anti-DDoS Origin Basic.
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 the 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 the crawlers from accessing all pages that are 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	Collects and stores all logs, enables near-real-time query and analysis, and provides online reports.
