Check Point SASE is a cloud-delivered Secure Access Service Edge (SASE) platform that combines networking and cybersecurity capabilities into a unified solution for modern enterprises and hybrid work environments. The platform integrates Zero Trust Network Access (ZTNA), Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), SD-WAN, and secure internet access to protect users, devices, applications, and data from a centralized system. Built on a global private backbone network, Check Point SASE helps organizations provide secure, low-latency connectivity for remote employees, branch offices, and distributed workforces. The platform simplifies deployment and management by consolidating networking and security operations into a single interface, reducing complexity and administrative overhead.

Headscale is an open-source, self-hosted implementation of the control server used by the Tailscale network, enabling users to keep full ownership of their private tailnets while using Tailscale clients. It supports registering users and nodes, issuing pre-authentication keys, advertising subnet-routes and exit-node capabilities, enforcing access-control lists, and integrating with OIDC/SAML identity providers for user authentication. The server is deployable via Debian/Ubuntu packages or standalone binaries, configurable through a YAML file, and managed via its CLI or REST API. Headscale tracks each node, route, and user in its database, supports route approval workflows, and enables features such as subnet routing, exit node designation, and node-to-node mesh within the tailnet. Being self-hosted, it gives organizations and hobbyists full control over their private network endpoints, encryption keys, and traffic flows, rather than depending on a commercial control plane.
