Introduction: Key Concepts of Mock Network Simulation Welcome to Day #98 of the 101 Days of pyATS (Vendor-Agnostic) series. Today, we focus on full-scale network simulations using pyATS integrated with VIRL or EVE-NG. For network engineers, being able to replicate complex production environments in a […]
Introduction In modern enterprise networks, compliance is dynamic. Users’ devices may fall out of compliance due to outdated antivirus, missing patches, disabled firewalls, or unapproved apps. Manual remediation is slow, error-prone, and disrupts productivity. Automated Remediation in Cisco ISE transforms NAC from static enforcement into […]
Introduction In modern enterprise networks, simply authenticating a device is no longer enough. Users bring multiple devices, mobile OSes enforce randomization, and threats like unpatched vulnerabilities or non-compliant applications are everywhere. Advanced Posture Multi‑Condition Compliance in Cisco ISE addresses these realities. By evaluating multiple conditions […]
Introduction In modern enterprise networks, security no longer ends at the perimeter. As organizations adopt cloud-based NAC, BYOD, and multi-vendor wireless solutions, a challenge arises: how do you centralize authentication, authorization, and auditing without duplicating identity stores or exposing internal RADIUS infrastructure directly to the […]
Introduction Imagine a visitor at Reception: instead of the receptionist reading out credentials, the visitor enters their mobile number and instantly receives a one-time code on their phone — quick, frictionless, and auditable. SMS OTP is the simplest multi-factor flow for guest access: low barrier […]

Introduction Imagine you’re managing the network for a global enterprise campus or hospitality chain. Every single day, you’re bombarded with requests: “We have 200 guests for today’s event… Please create accounts for them.” If you’ve ever sat in the Cisco ISE GUI and painfully clicked […]
Introduction When we talk about modern NAC (Network Access Control), the real battlefield isn’t just user authentication — it’s device trust, compliance, and dynamic enforcement. Traditional methods that relied on MAC addresses or static profiling are broken by today’s realities: MAC randomization in iOS/Android/Windows, multi-device […]
Introduction Imagine you’re at a large enterprise headquarters, or a university campus during orientation week. Thousands of visitors, contractors, or students are trying to get Wi-Fi access. Some are there for a single day, others for a semester. Marketing wants the login portal branded to […]
Introduction Imagine a user connecting to your network. At first, they get limited access — maybe just Internet. A few minutes later, Security updates their compliance posture: antivirus updated, corporate certificate installed, endpoint compliant. Now, instead of asking the user to disconnect and reconnect, Cisco […]
