Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
