    What is a VPN and how does it work?<\/strong><\/h3>\n\n

    VPN (Virtual Private Network)<\/strong> <\/a>is a technology that allows users to securely connect to the network, even if they use public or unprotected Internet connections. In fact, a VPN creates an encrypted tunnel between the user’s device and the VPN server, which protects transmitted data from interception by cybercriminals<\/strong>. <\/p>\n\n

    How does a VPN work?<\/strong><\/h4>\n\n

    A VPN uses various encryption protocols, such as OpenVPN<\/strong>, L2TP\/IPsec<\/strong>, or WireGuard<\/strong>, to hide your data from unauthorized parties. Every Internet connection that goes through the VPN is secured, meaning that third parties can’t see what sites you’re browsing, what data you’re sending, or what files you’re downloading. <\/p>\n\n

    \"How<\/figure>\n\n

    Application of VPN in companies<\/strong><\/h3>\n\n

    Many IT service providers, including Warsaw-based IT company RAMSDATA<\/strong>, offer comprehensive VPN solutions to help companies protect employee and customer data. VPNs<\/strong> are one of the more popular solutions in the business sector, allowing remote access to company resources in a secure and confidential manner.<\/p>\n\n

    Remote working and data security<\/strong><\/h4>\n\n

    In the pandemic era, remote working has become commonplace, and companies have faced the problem of protecting the data of employees connecting to company networks from different locations. VPNs<\/strong> have proven to be an ideal solution, allowing employees to securely access company documents and applications without risking privacy.<\/p>\n\n

    How do firewalls work?<\/strong><\/h3>\n\n

    Firewall<\/a><\/strong> is a device or software that monitors and controls network traffic. Its job is to block suspicious connection attempts and filter data entering and leaving the network. Firewalls are an essential tool for protecting against cyber threats<\/strong> such as DDoS<\/strong> attacks, phishing<\/strong> and ransomware<\/strong>. <\/p>\n\n
