In this comprehensive article, you will learn about VPNs with RAM-only servers.
Currently the best RAM-only VPN is: Private Internet Access.
Most VPN providers rely on hard disks to store and operate their VPN service. Data is stored in the hard disks until it is erased or written over with new data. This contradicts their no-log policy – “we do not store nor log your details.”
Additionally, storing data on the hard disks increases the security risk. If prying eyes such as hackers or the government get hold of the server, they can easily access sensitive information. To avoid the above scenarios, RAM-only servers are the way to go.
RAM-only servers use RAM modules instead of traditional hard disks (HDDs). The RAM modules store the operational data and code required for the VPN service to function.
These servers use a type of Random-Access Memory (RAM) which is volatile.
The information stored is lost if power is removed (by rebooting or turning off the server). In traditional HDDs, stored data is not lost even if power is removed.
The servers boot on a read-only image containing the operating system and other required software.
Since there’s no HDD, the contents of this image and other required files are loaded into the RAM modules. Essentially, every aspect of the VPN service takes place in the volatile memory (RAM).
It is easier to get data from traditional HDDs. Even if data is erased, some powerful software can still recover some data. Also, prying eyes can get encryption keys from the server configuration.
Additionally, the HDD can easily be accessed if the server is physically seized.
RAM-only servers make it harder for unauthorized parties to gain access to data. Hackers cannot install back doors and hence cannot steal private keys.
The OS and the necessary files are loaded on boot via a read-only image. The read-only image is hard to compromise since it is cryptographically signed.
Furthermore, no one needs to worry about sensitive data if the servers are physically seized. The VPN provider can initiate security procedures to reboot the servers remotely. Once this happens, all the data from the previous session will be lost.
Besides security, RAM-only servers ensure your activities will never fall to prying eyes. A simple reboot will wipe all the data in the servers. This also bolsters the VPN’s no-log policy.
The read-only image provides consistency to all servers. Loading the entire software stack at the boot gets rid of misconfiguration.
When using HDDs, incremental updates may alter some server configurations. In the end, there will be differences in server configurations, which might also lead to vulnerabilities.
ExpressVPN is one of the best VPNs that deploy RAM-only servers as part of a technology dubbed “Trusted Server Technology”.
PwC independently audited this technology and confirmed that it works as described.
Trusted Server Technology loads up the entire software stack when the server boots up. This ensures no inconsistencies, and it improves security and privacy.
Surfshark also uses RAM only-based servers. Surfshark rolled out a 100% diskless server infrastructure to increase privacy and security.
This infrastructure works similarly to that of ExpressVPN’s Trusted Server Technology.
Other VPNs that offer a RAM-only VPN service include Switzerland-based Perfect Privacy VPN and the Swedish AzireVPN.
Other reputable VPN service providers have also promised to join this trend.
RAM-only servers provide a way to eliminate the retention of your data. With a reboot, there won’t be any trace of sensitive information.
Also, these servers ensure that VPNs commit to their no-log policies regarding user activities.
Concisely, RAM-only servers ensure improved privacy, security, performance, and consistency.
Additionally, prying eyes such as hackers and other third parties won’t have unauthorized access to these servers. Even if the servers are physically seized, they won’t have any data.
Some people found answers to these questions helpful
Do RAM-only VPNs log data?
RAM-only VPNs such as ExpressVPN and Surfshark VPN do not log your data. The operational data that passes through their servers is wiped once a reboot is initiated. They have a friendly jurisdiction that doesn’t have mandatory data retention laws.
Do all VPN service providers use RAM-based servers?
No. Only a few VPN providers use RAM-only servers. They include ExpressVPN, Surfshark VPN, Perfect Privacy VPN, and AzireVPN. Nonetheless, other VPN providers have announced their plans to use RAM-only servers.
Can RAM-only data be tracked?
It is a futile process to track data in RAM-only servers. This is because data from the VPN service is secured with robust encryptions. The data is also anonymized and can be wiped anytime a reboot is initiated.
Can RAM-only VPNs be hacked?
Essentially, any VPN service can be hacked. But with RAM-only servers, your data will always remain safe. RAM-only servers make it hard for hackers to install backdoors or even gain access to server configurations. Furthermore, hacking will trigger security procedures that will initiate a reboot. Hence, all data will be lost.
Are RAM-only VPNs any better?
Yes, RAM-only VPNs are better than VPNs that use hard disks in their servers. RAM-only VPNs ensure utmost privacy, security, consistency, and performance and reinforce the no-log policy. Also, they are based in jurisdictions with no mandatory data retention laws.
