Microsoft Defender Enhances Open Wi-Fi Detection to Strengthen iOS Security
Microsoft Defender for Endpoint introduces enhanced open Wi-Fi detection capabilities.
Published: Mar 31, 2025
Key Takeaways:
- Microsoft Defender for Endpoint now features improved open Wi-Fi detection with a new caching mechanism.
- This feature prevents redundant alerts when users reconnect to the same unsecured network within seven days.
- A new Device Protection feature card on iOS introduces enhanced security capabilities like Web Protection.
Microsoft has released a couple of new capabilities for its Defender for Endpoint solution. The latest update brings enhancements to the open Wi-Fi detection capabilities for enterprise customers.
Microsoft Defender for Endpoint improves security by detecting when a device connects to an unsecured Wi-Fi network. It generates an informational alert in the Defender portal to help security teams manage and prioritize mobile security incidents. If a threat is detected, users receive notifications and guidance to switch to a secure network.
Currently, Microsoft Defender for Endpoint alerts the security team whenever a user connects to an unsecured Wi-Fi network. If the user disconnects and reconnects to the same network, a new alert is triggered.
Microsoft has introduced a new alert caching mechanism based on research and feedback from its Security Operations Center (SOC) teams. This update helps keep important alerts visible while reducing alert fatigue for security teams. Now, if a user disconnects and reconnects to the same open Wi-Fi network within seven days, a new alert won’t be triggered.
Updates to the Microsoft Defender app interface on iOS
Microsoft has announced upcoming enhancements to Defender for Endpoint on iOS, including a new Device Protection feature card. This update introduces key security features like Web Protection, Device Health, and Jailbreak Detection for enterprise users, with a redesigned interface for easier navigation.
Additionally, Microsoft has introduced Recommendation Cards to provide helpful security insights. The first card will display active alerts to ensure that users stay informed about potential threats. Key updates include updates to the dashboard, a feature card listing features, a detailed feature experience, and recommendation cards for alerts.
Earlier this month, Microsoft introduced several new features for its Defender for Endpoint solution. These include a new Phishing Triage Agent, Aggregated Reporting, Network Protection capabilities enabled by default on Android, and more.
