Introduction The Guest Device Registration Portal (GDRP) in Cisco ISE lets visitors self-register devices (MAC caching) and receive time-bound internet access—without burdening IT or exposing corporate networks. Customization matters because it directly controls security (device limits, expiries, CAPTCHA/OTP), user experience (branding, languages, fields), and operations […]
Introduction In modern enterprises, guest Wi-Fi access is no longer just a convenience — it’s an expectation. Whether it’s vendors, customers, contractors, or interview candidates, visitors expect to connect instantly and securely. But here’s the challenge: Cisco ISE’s Wireless Guest Access Flow solves this with […]

Introduction WPA2-Enterprise is the gold standard for securing enterprise Wi-Fi networks. Unlike WPA2-PSK (which uses a single shared key), WPA2-Enterprise leverages 802.1X authentication with a RADIUS server to provide per-user authentication, dynamic encryption keys, and granular network access control. In Cisco ISE, WPA2-Enterprise forms the […]

Introduction Wireless MAC Authentication Bypass (MAB) is one of the foundational network access control mechanisms in Cisco Identity Services Engine (ISE) — particularly critical in environments where certain wireless devices cannot perform 802.1X authentication (e.g., IoT sensors, IP phones, barcode scanners, printers). Unlike 802.1X, which […]
Introduction Cisco TrustSec (CTS) is a next-generation access control framework that goes beyond traditional IP-based segmentation. Instead of relying on static VLANs and ACLs, it leverages Security Group Tags (SGTs) to dynamically classify traffic, enforce policies consistently across the enterprise, and scale security for modern […]
Introduction The Sponsor Approval Workflow in Cisco Identity Services Engine (ISE) is a controlled guest access mechanism where guest account creation must be approved by a designated sponsor before the guest can gain network access. This process ensures: Think of it like a corporate front […]
Introduction Wireless network access control is only as strong as its weakest troubleshooting process. In the real world, even the best-designed Cisco ISE policies fail if engineers cannot quickly diagnose authentication issues, endpoint posture failures, or onboarding errors. Wireless Endpoint Troubleshooting in Cisco ISE is […]
Introduction In today’s enterprise networks, a single SSID is rarely enough. Organizations often need multiple wireless networks (SSIDs) to segregate traffic and apply different security policies — for example, separating corporate devices, guests, IoT devices, and contractors. However, without a central policy engine, managing authentication, […]
Introduction In the enterprise wireless world, security is a game of trust — and trust starts with knowing exactly who is connecting to your network and proving they are who they claim to be. PEAP (Protected Extensible Authentication Protocol) with Cisco ISE is one of […]
![[Day 41] Cisco ISE Mastery Training: Wireless 802.1X Authentication Overview](https://networkjourney.com/wp-content/uploads/2025/08/Day-41-Cisco-ISE-Mastery-Training-Wireless-802.1X-Authentication-Overview.png)
Introduction Wireless networks today are the primary access method for employees, guests, and IoT devices — but without proper control, they’re a security nightmare. Users can connect from anywhere, rogue devices can piggyback on open Wi-Fi, and sensitive resources can be exposed in minutes.Wireless 802.1X […]
