How to Easily Protect Against the Trident iOS Vulnerabilities

Now that the iPhone 7 has been released, Apple’s first remote jailbreak exploit seems like yesterday’s news. However, our recent data shows that approximately 80% of users are still using iOS version 9.3.4 and below, making them susceptible to three vulnerabilities, nicknamed Trident. These vulnerabilities install a backdoor allowing the attacker the potential for complete remote compromise of your iOs device. The Pegasus spyware can access your texts, photos, camera and microphone, and manipulate your data.

Don’t let users with compromised iOS devices put your organization at risk. You can prevent users running out-of-date iOS devices from accessing your corporate network and sensitive applications without the use of an agent. Through our new access control policies, administrators can either auto-update their policy to block any users who are not up-to-date, or block based on a specific version:
