Protecting the company's own IT infrastructure is essential. Risks such as extortion Trojans, DDoS attacks and cyber attacks of other kinds are omnipresent. IT security solutions are needed to ensure that the company's own website and IT are not endangered, for example, by hackers or force majeure (damage to IT can also be caused by lightning). According to the EU General Data Protection Regulation (GDPR), companies are required, among other things, to take appropriate measures to protect personal data. IT security software solutions are, for example, antivirus software, antispam software, backup and data protection software, encryption software, access control and authentication software and other IT security software.
