On Monday, Pakistan began blocking unregistered VPNs in a firewall trial, citing security risks. The Pakistan Telecommunication Authority (PTA) labeled unregistered VPNs as potential threats to sensitive data. PTA advised businesses, including IT firms and banks, to register IP addresses for uninterrupted VPN access, specifying usage. Since 2010, around 20,500 VPNs have been registered, according to PTA sources.
