Under CERT-In directions issued in 2022, VPN service providers operating in India must keep certain customer records, and some providers moved their servers out of India as a result. Using a VPN to commit fraud, access banned content or break the law remains illegal. Companies widely use VPNs for remote work.<\/p>\n<h2>How to choose a VPN<\/h2>\n<ul><li>Look for strong encryption (WireGuard or OpenVPN protocols).<\/li><li>Check for an independent audit of the no-logs claim.<\/li><li>Use a kill switch so traffic stops if the VPN drops.<\/li><li>Prefer well-known providers over unknown free apps.<\/li><\/ul>\n<h2>Frequently asked questions<\/h2>\n<h3>Does a VPN slow down internet?<\/h3>\n<p>Slightly, because data is encrypted and travels further. Good VPNs keep the slowdown small.<\/p>\n<h3>Should I use a VPN for banking?<\/h3>\n<p>Banking apps already use encryption. A VPN adds protection on public Wi-Fi, but some banks may block unusual VPN locations.<\/p>\n<h3>Is a VPN needed at home?<\/h3>\n<p>Usually not for security on a protected home Wi-Fi, but some people use it for privacy.<\/p>\n<h2>Keep exploring<\/h2>\n<ul><li><a href=\"\/index.php\/2026\/10\/12\/cyber-safety-basics\/\">Cyber safety basics<\/a><\/li><li><a href=\"\/index.php\/2026\/10\/12\/how-the-internet-works\/\">How the internet works<\/a><\/li><li><a href=\"\/index.php\/2026\/10\/13\/what-is-an-ip-address\/\">What is an IP address?<\/a><\/li><li><a href=\"\/index.php\/category\/technology\/\">More Technology articles on Tiwaripedia<\/a><\/li><\/ul>\n<p><em>Facts are based on widely accepted official, scientific and historical sources at the time of writing.
