Following Apple's announcement about new security tools, Konstantina Koukou, Cyber Security Specialist at Check Point Software Technologies in Greece, said:

“Apple is taking steps to put users in control of their privacy and security by adding optional features to the popular iMessage platform supported on iPhones/iPads and Macs. This added layer of security does not come without drawbacks, as the end user is now responsible for storing, backing up and securing their own encryption keys.”
"Our experience in mobile security shows that although Apple is taking steps to improve privacy, malicious apps, text/iMessage phishing and zero-day threats are not affected by them."
