The automatic process initiates as soon as you either transfer or incorporate a domain into your account. You have access to well-established and reliable libraries that facilitate your work. This setup minimizes the chances of your application experiencing downtime due to DDoS assaults. You can enhance the redundancy of your zones by allowing them to be mirrored to alternative DNS providers. Furthermore, you can redirect any emails from your domain directly to your current inbox. There are no restrictions on the number of records you can maintain within your zones. Each domain transfer comes with an additional one-year extension to your registration. To register, transfer, or renew domain names, a DNSimple subscription is necessary. Please note that the fees associated with domain registration, transfer, and renewal are separate from your subscription costs. This comprehensive approach ensures that your domain management is both efficient and effective.

CacheGuard
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.
