This skill provides comprehensive guidance on establishing secure, high-performance connectivity between on-premises data centers and major public cloud providers (AWS, Azure, GCP). It covers various connection options, including Site-to-Site VPN, AWS Direct Connect, Azure ExpressRoute, and GCP Cloud Interconnect. Use this skill to design and implement complex hybrid network patterns (e.g., Hub-and-Spoke, Multi-Cloud), ensuring high availability, proper routing (BGP), and adherence to security best practices.

AWS Verified Access is a Zero Trust Network Access (ZTNA) service that provides secure, VPN-less access to internal applications. It uses granular Cedar policies to evaluate user identity (integrating with Okta, IAM Identity Center) and device security posture (CrowdStrike, Jamf) in real-time. Use this guide when replacing traditional VPNs, enforcing strict conditional access controls, or deploying multi-account Verified Access infrastructure across AWS.

This guide details the comprehensive deployment of Cisco Duo Multi-Factor Authentication across critical access points like VPN, RDP, SSH, and web applications. It covers setting up the Duo Authentication Proxy, implementing adaptive access policies based on risk and device health, and deploying phishing-resistant methods like WebAuthn/FIDO2, ensuring compliance with NIST standards. Use this when hardening identity access management or establishing robust security controls.

A comprehensive guide to configuring pfSense firewalls for robust network security. This skill covers setting up complex network segmentation across multiple zones (DMZ, internal, guest, IoT), implementing granular firewall rules, configuring NAT for port forwarding, and establishing site-to-site or remote-access VPN tunnels using IPsec or OpenVPN. Ideal for network engineers deploying perimeter or internal firewalls.

A comprehensive guide detailing how to implement Zero Trust Network Access (ZTNA) using Zscaler Private Access (ZPA). This process replaces traditional VPNs by deploying App Connectors, defining precise application segments, and establishing granular access policies. Access is strictly controlled based on user identity, group membership, and device posture (health check), ensuring that users only reach authorized resources without needing network-level connectivity.

A comprehensive guide on deploying Cloudflare Access and Tunnel to establish a Zero Trust Network Access (ZTNA) solution. This method replaces traditional VPNs by securely exposing self-hosted internal applications (web, SSH, RDP) without opening inbound ports. It integrates identity-aware policies, device posture checks, and robust identity providers (Okta, Azure AD) for highly secure, least-privilege access.

A comprehensive guide for implementing enterprise-grade Security Access Service Edge (SASE) architectures using Palo Alto Networks Prisma Access. This skill covers configuring ZTNA connectors, GlobalProtect agents, security policies, and device posture checks (HIP) to provide unified, cloud-delivered security, replacing traditional VPNs and maintaining zero trust principles across remote and branch offices.

This guide details deploying Tailscale (or self-hosted Headscale) to create a WireGuard-based zero trust mesh VPN. It establishes encrypted peer-to-peer connections between devices, eliminating the need for traditional VPN servers. Features include identity-aware Access Control Lists (ACLs), subnet routing, and secure connectivity for compliance-driven architectures. Use this when enforcing granular, identity-authenticated access control.

A comprehensive guide to implementing Google's BeyondCorp zero trust access model. This solution enforces identity- and device-aware access control using Cloud IAP and Access Context Manager, effectively replacing traditional VPN infrastructure. Use this to secure remote and hybrid access to GCP-hosted or on-prem applications by requiring granular device posture checks and strong user authentication.

This guide details implementing Zero Trust Network Access (ZTNA) across major cloud providers (AWS, Azure, GCP). It replaces traditional VPNs by enforcing identity-based, context-aware access controls using identity-aware proxies and micro-segmentation. Use it to secure cloud workloads, limit lateral movement, and comply with modern security standards like BeyondCorp.

This skill guides the end-to-end deployment of Zero Trust Network Access (ZTNA) using Zscaler Private Access (ZPA). It enables secure, granular, and context-aware access to internal applications without placing users on the corporate network. Ideal for hybrid and remote workforces needing robust security controls and regulatory compliance beyond traditional VPN limitations.

HashiCorp Boundary is an identity-aware proxy that establishes secure, zero-trust access to infrastructure resources, eliminating the need for traditional VPNs. It enforces a default-deny model and integrates with HashiCorp Vault to dynamically broker credentials. This ensures just-in-time, least-privilege access, automatic credential revocation, and comprehensive session recording for strict compliance and auditing.
