Firewalls protect the gateway to your network and to your data and applications, and maintaining threat protection is essential.
The problem is that firewalls are pretty stupid – they are like a security guard on the door of a club, allowing in only those guests who are on the list and rejecting anyone who Is not.
The problem is that hackers and emerging threats have become much more sophisticated in gaining entry, and in addition, modern business networks are much more porous than they once were – there are now multiple entry points into a network, and firewalls can be bypassed.

Cloud-based services, aka services that store your information on a server as opposed to your own hard drive, have been embraced by individuals and business users alike.
Everything from banking apps, email and even social media accounts are now all accessible via the Cloud on multiple devices with nothing more than an internet connection, which means we’re able to enjoy a greater range of services than ever before.
However, cloud accounts require passwords to restrict user access, and with so many accounts to keep track of, it’s tempting to use the same run-of-the-mill passwords for multiple services.
