1. Privacy

I’ll start with a comparison of the most important aspect of any VPN - privacy. During review I will consider whether VPN logs anything (IP address, traffic, DNS logs, bandwidth, or any type of timestamps) and the jurisdiction of VPN’s country of origin.

NameAvast SecureLineFlashVPN
IP addressYesYes
DNSYes Yes

Avast SecureLine is located in Czech Republic which is part of 5 9 14 eyes countries and is not part of enemies of the internet countries while FlashVPN is located in Hong Kong which is not part of 5 9 14 eyes countries and is not part of enemies of the internet countries.

It’s important to note that If you are like me and you will be using VPN only to unblock GEO-restricted content, privacy will not be that important factor but it’s still essential for any VPN.

2. Features

The next category I want to compare are features of Avast SecureLine and FlashVPN such as kill-switch, unblocking of streaming, support of P2P traffic (torrenting). I am a heavy user of various streaming platforms so for me it’s important whether VPN unblocks major streaming services such as Netflix, Hulu, Amazon Prime, HBO or BBC. I don’t do much torrenting but it’s always good to use a VPN while doing so. If this is an important factor for you, definitely look for a VPN which supports P2P traffic.

Streaming (Netflix)NoNo
P2P traffic - torrentsYesNo

As you can see from the comparison table above, Avast SecureLine has kill-switch, doesn't support streaming services, and supports torrenting. On the flipside FlashVPN doesn't have kill-switch, doesn't support streaming services, and doesn't support torrenting.

3. Speed

Being hidden behind VPN shouldn’t limit the speed of your connection. I’ve measured the speed of each VPN against a 100mbps connection - which should be sufficient for any activities including heavy streaming in 4K or downloading large files.

In my test Avast SecureLine was more on the average side while FlashVPN had below average speed. If there were no limits in speed on a 100mbps connection, I consider VPN a “fast” one. If the speed is limited somehow but still achieving decent values, I categorize it as “average”. The “slow” is usually used for VPNs which limit your bandwidth significantly.

4. Security

I will start by comparing the type of encryption Avast SecureLine and FlashVPN use, what tunnelling protocols are available, and finally we’ll test whether it leaks the IP address or DNS.

Tunneling protocolsOpenVPN UDP, IKEV2 and IPSecUnknown
IP leaksYesYes
DNS leaksYesYes

The most important factor of a VPN service is a strong encryption of the traffic which is forwarded through the VPN servers. The most common encryption types in cryptography are SHA encryption or AES encryption which are not really comparable against each other. There might be different lengths of encryptions (eg. 128-bit, 256-bit, 2048-bit) and while usually the higher is the better, for most use cases you will be fine with any encryption. Watch-out if there is no encryption at all. Avast SecureLine uses 256-bit and OpenVPN UDP, IKEV2 and IPSec protocol and FlashVPN uses Unknown and es 256-bit and Unknown protocols. I’ve tested both VPNs also for IP and DNS leaks and Avast SecureLine had no IP leaks and No DNS leaks while FlashVPN had No IP leaks and No DNS leaks. 

5. Price

Probably one of the most important decision factor for the majority of users will be price. Shocking? Not really. We all love to compare things and I am not different. It’s always good to get the best value for your hard-earned money, isn’t it? So let’s see whether Avast SecureLine or FlashVPN is cheaper.
