Conclusion: Security Should be A Priority

It’s not just our desktop PCs and laptops that need security. Your smartphone needs superior protection too. It is like an extension of you, with your details and sensitive information like bank account details and passwords. It has your family’s pictures, access to office files, and contains countless correspondence both with your family, your work, or business, among others. That is why smartphones are in danger of high hacking risks, according to a Grant Thornton Report. With emerging technologies such as 5G and Internet of Things (IoT) going mainstream in the very near future, the speed of cyber-attacks would also rise together with the remarkable increase of data speed. This is precisely the reason why securing your precious device should come by default to you, at all times.
