The rules changed in 2026: no sponsor requirement, a SOC 2-based entry class, and a progressive path upward. The current map of FedRAMP classes, DFARS 7012, CMMC, and impact levels.
Read articleOne SSID, thousands of campuses, and a password that never leaves home. How eduroam's federated RADIUS hierarchy authenticates roaming users against their home institution, what joining requires, and why logins are moving to EAP-TLS certificates.
Read articleThe Department of War paused CMMC's third-party certification rollout in July 2026 - but DFARS clauses and NIST SP 800-171 never paused. What defense contractor wireless networks still have to do, and why the pause is the best window to fix WiFi authentication.
Read articleThe same week Altman declared the singularity, an AI model reportedly escaped its sandbox and attacked a third-party platform. Skip the philosophy debate: AI agents are identities now, and the practical control is watching what they can reach.
Read articleThe phone setting that joins airport and stadium WiFi by itself, explained: how Passpoint works, why it is safer than normal public WiFi, and when to turn it off.
Read articleThe sign-in page on hotel and airport WiFi, explained: how the walled-garden redirect works, why the login page sometimes never appears, and how to force it open on any device.
Read articleBlastRADIUS showed that RADIUS/UDP fails against a modern attacker, and the IETF is deprecating cleartext transport. What RadSec changes, where it is already mandatory, and how to migrate.
Read articleAirbnb is testing coworking day-pass bookings - new walk-in revenue, and a stream of unvetted visitors on networks built for trusted members. How to say yes to booking platforms without opening your network to strangers.
Read articlePhones now change their WiFi MAC address by default - and captive portals, MAC allowlists, and visitor analytics quietly break. What changed in iOS and Android, and how to build authentication that survives.
Read articleA practical guide to offering guest Wi-Fi in hospitals and clinics without putting ePHI at risk. Learn about network segmentation, authentication tiers, audit logging, and privacy-first captive portal design.
Read article802.1X proves who you are. It doesn't decide whether that identity, on that device, in that context, should be on the network at all. That's the job conditional access does — and on wireless, the decision happens at the RADIUS layer. Here's how policy-based access control works, what it can evaluate, and how to roll it out without locking anyone out.
Read articleEvery organization has a network. Every network is an identity security boundary. Network Identity Security is how you enforce it — replacing WiFi passwords with certificates, wiring every person, device, and AI agent into one zero-trust fabric, and catching anomalies before the session even completes.
Read articleCredentials are now the perimeter — and attackers know it. ITDR is the category built to catch identity abuse that endpoint and network tools miss. Here's what WiFi ITDR is, why RADIUS and captive portals need their own detection layer, and how the threat model maps to MITRE ATT&CK.
Read articleEvery enterprise identity system was designed for a world where humans were the only entities connecting to the network. AI agents are ending that assumption, and the security gap at the network layer is widening fast.
Read articleYour WiFi network generates terabytes of operational data every month. AI turns that raw signal into actionable intelligence -- from smarter authentication to predictive capacity planning -- so your team can stop firefighting and start optimizing.
Read articleRADIUS is the backbone of network access control, handling billions of authentication requests every day. Whether you manage WiFi, VPN, or wired networks, understanding RADIUS is essential. This guide covers everything from protocol fundamentals to choosing the right RADIUS solution for your organization.
Read articleMost businesses still use a shared WiFi password for network access. That single password is one of the biggest security gaps in your organization. Here's why WPA2-Enterprise with individual credentials is the standard your business should meet -- and how the migration is easier than you think.
Read articleOn-premise RADIUS servers served their purpose for two decades. But in 2026, managing your own FreeRADIUS, NPS, or ISE infrastructure is overhead that delivers no competitive advantage. Here's what you gain by moving RADIUS to the cloud.
Read articleHotspot 2.0 eliminates captive portals and delivers automatic, encrypted Wi-Fi connections on public networks. This guide covers the top solutions, hardware requirements, and a step-by-step implementation path from 802.11u configuration to OpenRoaming federation.
Read articleIoT devices are flooding enterprise networks but most lack basic security features. Learn how to use network segmentation, RADIUS-driven policies, and device profiling to contain the risk without blocking the innovation.
Read articleThe traditional"castle and moat" security model assumes that devices inside your network are trustworthy. Zero Trust flips this assumption entirely. Here's how to implement Zero Trust principles for your enterprise Wi-Fi infrastructure.
Read articleShared Wi-Fi passwords are a relic of a simpler time. In today's threat landscape with high-speed Wi-Fi 6 and converged 5G networks, certificate-based authentication isn't just better security - it's the foundation of zero-trust wireless access.
Read articleA comprehensive guide to Wi-Fi data privacy for businesses. Learn what data your network collects, your legal obligations, and how to protect customer information while delivering great connectivity.
