The VPN is overall secure as it uses various privacy-enhancing features to keep customers’ anonymity. The VPN doesn’t use standard OpenVPN. Instead, it uses Catapult Hydra – the proprietary tunnelling protocol which provides relatively fast speeds and incorporates perfect forward secrecy. You can use the IKEv2 protocol enough for mobile devices to maintain stable connections. It is a top-notch kill-switch feature, which could stop all the coming traffic in case your connection drops.
Moreover, the VPN uses advanced Split-Tunneling and Smart VPN features. Besides, the VPN is protected from all IP, DNS, or WebRTC leaks. Considering its features, the VPN overall provides a secure service to its customers.
