AppEx CloudWAN vs CacheGuard-OS

AppEx CloudWAN combines a global network backbone, WAN optimization, and SD-WAN connectivity. Its multi-cloud backbone has more than 600 geographically distributed Points of Presence. The SD-WAN can use connections such as broadband and MPLS and route traffic over efficient paths. AppEx ZetaTCP pairs AI-driven TCP acceleration with Real-Time TCP Tunnel technology to improve performance under latency and packet loss. AI/ML observability provides visibility into traffic, security events, bandwidth use, and application performance; a unified dashboard brings together network and security configuration, policy monitoring and enforcement, reporting, and alerts. Connectivity includes Oracle, Tencent, Alibaba, AWS, Google, and Azure environments, plus SaaS applications such as Office 365 and Salesforce. Users can connect through CloudWAN CPE, the software client, or their own VPN gateway using IPSec, SSL, or GRE. AppEx describes a vendor-agnostic SASE approach with SWG, CASB, FWaaS, ZTNA, WAF, and XDR capabilities. Pricing is on request, billed by bandwidth per year, month, or day. A free trial is available.

CacheGuard-OS turns an x86 or x64 machine into a Linux network appliance for securing and optimizing network traffic. Its combined functions include firewalling, IPsec VPN, web application security, content caching, antivirus inspection and traffic shaping. Install it on bare metal or as a virtual machine, including VMware, Hyper-V and Proxmox. Administrators can configure an appliance through a CLI or browser-based Web GUI; a Manager can centrally manage multiple Gateways. The firewall uses stateful packet filtering, NAT and PAT, and the maker says it blocks common attacks such as DoS, SYN flood and IP spoofing by default. URL filtering supports lists and regular expressions, with LDAP or AD/Kerberos authentication. The WAF offers generic and custom filters, IP reputation lists and antivirus scanning. WAN tools include HTTP compression and multi-WAN routing with automatic failover. The OS is free to use. Optional subscriptions cover URL blacklists and extended antivirus signatures; Standard and Premium support also require paid subscriptions.
