We take good care of your files

In recent years, IT security has steadily climbed higher and higher up on the public agenda. Our customers should be confident that their files are kept safe with us - and therefore we go through great efforts to maintain a bulletproof IT infrastructure.

"I would go so far as to claim that we have developed an infrastructure that cannot be hacked," says managing director Aage Agergaard.

"It is not just the files for the various tasks that must be secured. For example, when we sign a NDA it really puts a lot of pressure on us to ensure that our IT infrastructure can meet the stringent requirements that are often stipulated in a NDA."

The high level of security can be attributed to the fact that Hjerno has developed an internal network without internet connectivity, which means that the computers in the production cannot go online. If an employee needs access to his mail or to the Internet, this is done via a terminal server – the computer is at no point connected to the intranet.

"It also provides the additional security measure that our computers never need security updates as they are never in contact with the outside world - and this is really kind of amazing in itself," explains Aage Agergaard.

Private server network
All operational files are located at Hjerno’s private server network consisting of 15 servers with full redundance. The servers are equipped with UPS (Uninterruptible power supply), which means that a possible power outage is countered by our internal backup power supply that shuts down the servers safely with no loss of data. In addition, a physical backup of all files is created, just as an incremental backup is created every time a file is changed.

Furthermore, we have established CAT6 cabling in the form of extra shielded network cables to ensure speed and stability. And every night an additional backup is made, which is physically located in a secure place away from the servers.

"In this way, we are 100 percent sure that our files will not be hacked. And there is also no risk that we will lose our customers' files," states Aage Agergaard.
