Description
CacheGuard-OS is an open-source Linux-based UTM gateway appliance OS that has been in active development since 2002. It is designed to run on commodity x86 hardware and act as the default route between an internal network and the internet, replacing the ISP-provided router as the traffic checkpoint.
The stack integrates: Squid (web cache and proxy), ClamAV (web antivirus), ModSecurity (WAF), StrongSwan (IPsec/IKEv2 VPN), IPRoute2 (QoS and WAN load balancing), NetFilter (stateful firewall), SSL inspection, and URL filtering. All components are configured through a web-based admin interface rather than directly, making the platform accessible to operators without deep Linux expertise while remaining auditable by those who want to inspect the underlying configuration.
The OS has been open-source since its first release — source ships on every installed appliance. It was recently published publicly on GitHub to make the codebase easier to browse and audit.
Target deployments are small to medium networks — SMBs, schools, and branch offices — where a commercial UTM appliance is overkill on budget but the threat surface is the same. Runs on bare metal or common hypervisors (VMware, VirtualBox, KVM, Hyper-V). No vendor lock-in, no subscription, no licence cost.

Description
DTS PlatinumCache C4, created by Data Transmission System Incorporation, is an advanced caching solution designed to address storage bottleneck issues effectively. This caching system incorporates various policies including Write-Back, Write-Through, Write-Only, and Pre-fetching to optimize performance. Utilizing RAMDISK as its caching medium, the system targets SD cards in Android devices for improved data management. By reading and writing data between the cache and the SD card, DTS PlatinumCache C4 significantly boosts throughput. Its architecture is tailored to meet the diverse requirements of clients, whether they are small businesses or large enterprises. The performance improvements are substantial since data transfers occur directly from RAM, leading to faster access times. Notably, the MCell-II SSD represents a pioneering advancement in the industry as the first SSD version of a hybrid memory disk, boasting impressive specifications such as 30,000 IOPS for random reads and 26,000 IOPS for ultra-fast random writes. The DTS chip plays a crucial role in managing write operations effectively, ensuring longevity and durability. Additionally, DTS PlatinumCache optimizes the chunk size for writing to the SSD, further enhancing its efficiency and performance in data handling.
