Internet traffic has exploded because people are much more connected than before. Both ordinary individuals and professionals, most of them unaccustomed, have used different digital services for their daily needs. Especially professionals who have seen their usual means and methods of exercise switch to telework. Alexis Kuperfis noted, "With the spread of coronavirus, many companies are forcing their employees to work from home, which puts unforeseen stress on remote networking technologies and poses bandwidth and security issues. ».

While over the past 10 years, the names of teleworkers have increased to 4 million. In recent months the coronavirus pandemic and its effects have caused a meteoric increase in this number of kinds to make it difficult for machines and computer programs to ensure a proper and efficient operation of the computer system.

On the other hand, VPN use in the United States grew by only nearly 53% between March 9 and 15, according to VPN provider Atlas. This use has continued to grow since then. On the Italian side, an advance in the use of VPNs was observed to the tune of 112%. Atlas VPN Chief Operating Officer Rachel Welch said in a statement: "We estimate that VPN use in the U.S. could increase by more than 150 percent by the end of the month."

The companies unanimously recognized that it is not at all obvious to support all these network technologies, especially with users who are scattered on different sites and remotely, in direct contact with the data centers. Knowing here the significant security risk.That's why security professionals, information systems managers where the entire IT team should deploy a set of protocols to ensure that the connection meets the security standards set by the company. "Home broadband elements, such as ISP and DNS and Wi-Fi, should really be part of a company certification of appropriate networks for home work," said Tom Nolle, President of CIMI Corp. He later stated: "I find that DNS services like Google's are less likely to be overloaded than ISP services, suggesting that users should be forced to adopt one of them. OpenDNS is also good. The security of home Wi-Fi networks is also a problem. ». It also means "IT professionals should require workers to submit screenshots of their Wi-Fi configurations in order to validate the encryption used. Homeworkers often bypass much of the integrated security in companies. ».

Regarding the use of VPN, the various players in the sector do not have a unanimous opinion. "The players in the sector are divided on the use of split tunneling to minimize capacity problems due to coronavirus. VPNs can be configured to allow "split tunneling," where only traffic for the enterprise network passes through the VPN," said Mr. Wertkin of BlueCat. "The rest of the traffic goes directly to the internet in general, which means that it is not subject to the security controls imposed by the tunnel and the tools of the corporate network, which is a security problem. He adds. Such a configuration can very easily cause the compromise of terminals used by remote collaborators via the Internet. Such a scenario that would automatically endanger all of the company's computer systems and networks as well as the data managed by the company.
