After a user configures prompts and an execution frequency, the system automatically triggers AI analysis and pushes results at the scheduled time, eliminating the need to manually initiate a conversation.
2026-10-08
Two new automatic analysis capabilities for AI Agent
Firewall security reports are automatically generated and pushed at the configured frequency. Alarm analysis and noise reduction automatically marks alarms that have no real impact.
2026-10-08
Streamlined settings entry across multiple pages
A settings entry is added to the upper right corner of the Firewall Toggle, Access Control, Network Honeypot, and Log Analysis pages. The corresponding settings previously under System Settings > General Settings are now configured directly on each page without redirection.
2026-10-08

2026-10-08
CFW account-level monitoring metrics
TCOP adds CFW account-level monitoring metrics. NAT edge and VPC edge cluster modes support connection quantity (concurrent connections, new connections) and bandwidth (inbound/outbound peak, bandwidth utilization, and total bandwidth for VPC edge) monitoring.

Documentation
Optimization of Network Honeypot CLB probe deployment
CFW Network Honeypot upgrades the deployment mode of CLB probes by canceling the original relay scheme that requires users to prepare forwarder CVMs themselves and adopting a direct connection mode where a subnet and private IP address are selected. After a probe is created, the firewall automatically binds and unbinds CLB backend RSs, reducing user Ops costs, eliminating the single point of failure risk of forwarders, and improving the stability and reliability of traffic forwarding links.
2026-08-15
Extension of EKS asset protection for internet boundary serial firewall

By excluding traffic capture on non-critical ports, it effectively reduces unnecessary log storage, helps users optimize log storage costs, and ensures complete recording and analysis of core business traffic.
2026-08-15
New Hong Kong (China) identity card (HKID) identification rule for sensitive data leakage detection
Sensitive data leakage detection in NDR traffic risk analysis adds a Hong Kong (China) identity card (HKID) identification rule, which supports the identification and detection of Hong Kong (China) identity cards (HKID).
2026-08-15
Fixes for attack source false positives and multiple experience optimizations
CFW fixes the issue where attack sources are falsely identified in some scenarios, improving threat identification accuracy. Traffic monitoring adds a feature for viewing bandwidth trends over the last 30 days, helping users with capacity planning and anomaly analysis. Log storage policies are adjusted to be more flexible, and historical log retrieval remains supported after service expiration, ensuring the continuity and integrity of security operations.
2026-08-15
Launch of pay-as-you-go billing mode
CFW launches a new pay-as-you-go billing mode for small-scale user groups whose protected peak bandwidth must be below 10 Mbps and whose maximum number of protected IP addresses is 10, simplifying the billing process and lowering the usage threshold. The pay-as-you-go edition is currently in the grayscale testing phase. To purchase it, contact your account manager.

Documentation
Internet Firewall optimization
This bandwidth is automatically assumed by north-south bandwidth without separate allocation, elastic protection configurations are automatically merged, serial firewalls no longer consume general instance quotas (occupied quotas are automatically returned), bandwidth management is simplified, and bandwidth usage flexibility is improved.
2026-07-08
Traffic Log Optimization
CFW flow logs add two new columns: "Final Action" and "Access Control rule". They mark the actual allow/block result of each session after multi-module flow control (supporting differentiation between Access Control blocks and Intrusion Defense blocks) and directly display the details of the matched Access Control rule.
It also supports filtering and exporting based on final action and Access Control rule ID/rule description, allows restoring the actual session results in a single view, and reduces manual cross-log comparison.
2026-07-08
Log Storage Optimization
CFW log storage settings are optimized, removing the limit on the number of modifications to retention period and storage type (only the edition restriction is retained), and adding longer retention period options of 365 days and 730 days.
2026-07-08
Enterprise Security Group Optimization
CFW Enterprise Security Group supports managing more asset instance types, improves policy delivery speed, further expands the coverage of private network micro-segmentation control, and enhances configuration efficiency.
2026-07-08
NDR AI Security Exposure Surface
NDR adds AI exposure surface and exposure surface risk detection capabilities, addressing the core operational demands of "which AI assets are exposed, on which ports they are exposed, and whether there is high-risk access".
Through deep full-traffic analysis and passive identification, it identifies the port exposure paths of AI services such as large model APIs, Agents, and MCP Servers, and identifies real risks such as unauthenticated public network exposure, plaintext HTTP transmission, and overseas access.
It provides a dual view of "exposure surface mapping + risk monitoring", helps enterprises transition from AI asset discovery to risk governance, and assists in the convergence of AI exposure surfaces.
2026-07-08
