Is there a no-logging policy in place?
One key element of security you need to consider when deciding on a VPN is how much information the VPN provider collects. To find your answer, what you should be looking for is a comprehensive no-logging policy.
Essentially, this will tell you in no uncertain terms that your VPN service does not collect any information that you broadcast on the network. This information could include personally identifiable information (PII), download data, search history, or whatever other sensitive data you don't want to share.
Bank check the provider's privacy policy to come across if the company keeps any other information, and if and then, for how long – a VPN server is just as vulnerable to cyberattacks as whatever other, and even with adequate security measures in place, they could notwithstanding be targeted. Plus, any data stored may exist handed over to authorities if the provider is compelled to do so by a regime.
What is the level of encryption and which protocols are bachelor?
A VPN encrypts your internet traffic, making it almost incommunicable for cyber criminals to decipher, even if they practice somehow intercept it. Most VPN providers utilise the well-known and highly-secure AES-256 encryption equally standard
However, encryption is just ane role of the suite of security features used by VPN providers to safeguard your web traffic. There are other processes involved, but they all autumn under the umbrella of good security do.
OpenVPN is still widely regarded as the nearly secure VPN protocol and is used past almost all VPN providers, but the recently launched WireGuard is too proving very pop also. OpenVPN uses a custom security protocol that provides a ameliorate combination of speed and security than earlier alternatives. And, although WireGuard is generally considered faster, OpenVPN is still more widely used.
Some providers similar Hotspot Shield have developed their own protocols – in Hotspot Shield's case, the Catapult Hydra protocol – and these take pros and cons. Some prioritize speed over security, and a number aren't open source. Still, the new wave of in-firm protocols are largely based on WireGuard, and if you want to larn more than, cheque out is WireGuard secure.
Does information technology accept a kill switch?
Ane of the most of import security features on a VPN is its kill switch. This essential part ways that if your VPN loses its connexion, your browsing session will be terminated. Or, some VPNs volition instead cancel predetermined programs or sites that you lot don't desire to admission without VPN protection. If you continue browsing without VPN protection, your internet traffic could be intercepted.
In brusk, if you are looking for a VPN with tiptop-notch security features and one of the options you're considering doesn't have a kill switch, ignore information technology. Y'all're far improve off choosing a similar alternative with this characteristic in identify.
Is your IP address truly safe?
To gauge the reliability and security of your VPN provider, y'all should do some digging and find out whether or not information technology has a history of vulnerability – in particular, whether any IP address leaks have occurred.
Masking your IP accost is the top priority of a VPN service, and then when this is breached and your IP accost is leaked, the platform is essentially failing. The all-time VPN providers, like ExpressVPN, use Perfect Forrard Secrecy (PFS), a technique where new privacy keys are created every time y'all showtime a VPN-enabled browsing session so even if your traffic is somehow decoded it couldn't be used to access past or future data. Your key will besides be changed at intervals during use to ensure maximum prophylactic.
Standard encryption models use a unmarried privacy, or individual encryption, key that is used to decrypt all data both electric current and historic. If an assaulter is able to obtain admission to this central they can potentially harvest a keen bargain more information.
Another feature to look out for is IPv6 leak protection. Although IPv6 is more than secure than the previous generation of IP addresses, namely IPv4, it is even so vulnerable.
Some VPNs fail to find IPv6 traffic because it is unsupported by many websites, and as a result, a DNS request may be made outside of the VPN. IPv6 leak protection counteracts this by disabling IPv6 traffic during a VPN session.
Bottom line
Although VPN technology has many functions, many users turn to it for the security it provides. The thing is, non every provider offers the same level of protection. Many volition choose to focus on streaming and torrenting features, and the highest levels of security could well be a secondary thought.
If security is your priority, before you cull a provider, use this article as a checklist. If the service you have in mind doesn't tick all the boxes, then opt for another. Lots of people may want to try out a free VPN before committing to a paid plan. If you exercise decide to go down this route, be enlightened that well-nigh free services don't offer close to the level of protection you'll receive from a paid-for provider.
