BlueCat Horizon vs Tailscale

BlueCat Horizon coordinates DNS, DHCP, IP address management, and network operations across hybrid and multicloud environments. Its first generally available service, Horizon DDI Orchestration, combines SaaS-hosted IPAM with centralized DNS and DHCP orchestration. Hosted IPAM provides a central inventory of networks, subnets, and IP addresses. Lightweight agents connect existing DNS and DHCP environments, while local agents and service points can keep services running locally under Horizon's SaaS governance. Network teams can standardize changes and synchronize data through a shared interface and API. Integrations include Microsoft Active Directory, BIND, Kea, cloud DNS, third-party components, and BlueCat solutions. Granular role-based access supports delegation by region, business unit, or function. The subscription is metered by Unique Active IP, which includes addresses with DNS records, DHCP leases or assignments, or recent active discovery. Pricing is on request, and BlueCat offers a trial request form without stating a duration. Advanced DNS services are marked as coming soon; observability and AI-assisted operations are described as platform vision rather than general-availability commitments.

Tailscale is a zero-config VPN for connecting users and devices across a network. It uses WireGuard to form low-latency peer-to-peer connections, which Tailscale says are end-to-end encrypted so it cannot read users’ traffic. Administrators can use access control lists to specify which users may connect to which devices. Supported identity providers handle authentication, and SCIM supports user and group provisioning. Monitoring features include configuration audit logs, network flow logs, webhooks, and log streaming to SIEM partners. Device posture information can be used in connectivity rules. Taildrop transfers files between devices, while node sharing lets users share a node without exposing it to the public internet. The service runs on Android, iOS, Linux, macOS, web, and Windows. Personal is free forever for non-commercial use and supports up to six users; Standard costs $8 per user per month. Premium costs $18 per user per month and includes priority support.
