Surfshark has unveiled Dausos, a brand new digital non-public community (VPN) protocol designed to enhance consumer-grade VPN speeds and safety.
What’s Dausos?
Named after the Lithuanian phrase for heaven and as a nod to ascendence, Dausos is Surfshark’s proprietary VPN protocol, which the corporate hopes will set it other than the likes of WireGuard, OpenVPN, and IKEv2 as a purpose-built protocol designed for client VPN use.

The corporate says that whereas many protocols utilized by VPN networks right now weren’t initially designed for client use — and have been as an alternative merely tailored to be match for goal — Dausos has been particularly constructed for this process.
What makes it completely different?
Based on Surfshark, Dausos makes use of AEGIS-256X2 as an alternative of the extensively used AES-GCM, however the important thing distinction is that it offers a separate, devoted visitors tunnel for every consumer. Usually, you’d share these tunnels with different VPN consumer visitors, however by forging particular person paths, the hope is that Dausos creates a cleaner, extra streamlined expertise and reduces the potential danger of visitors contamination or publicity.
In a Reddit thread, Karolis Kačiulis, Main System Engineer at Surfshark, stated:
“When customers share a tunnel, one consumer’s visitors load can intrude with one other’s, which means your packets get dealt with slower as a result of the server is busy processing different customers’ packets. With Dausos, every consumer will get a devoted tunnel, in order that drawback goes away.”

Surfshark says this protocol might present as much as 30% sooner speeds than different protocols, together with WireGuard — the protocol Surfshark, together with most different VPN suppliers — makes use of by default.
Moreover, using AEGIS-256X2 encryption is a safety enchancment and can also assist defend in opposition to future assaults as a post-quantum answer.
Backing Dausos claims
Introducing any new main encryption expertise or protocol at all times carries dangers, so to again up its claims, Surfshark engaged impartial auditor Cure53 to conduct an evaluation.
“With no findings rated at Essential or Excessive severity inside the precise Dausos protocol itself, the audit outcomes mirror a secure and resilient platform,” the evaluation (.PDF) reads. “The Surfshark crew demonstrated a major dedication to safety by remediating the vast majority of the findings instantly following the testing section.”
This doesn’t suggest it has all been honest winds, nevertheless, as upon launch, some testers discovered Dausos didn’t carry out effectively with residential connections. Nonetheless, Surfshark quickly developed and deployed a repair, which seems to have resolved the difficulty.
Set up, testing, and ultimate ideas
In the meanwhile, Dausos is simply accessible on macOS, though Surfshark plans to roll out the protocol to different platforms sooner or later.
To check out the brand new protocol, guarantee your app is updated with the most recent model. Nonetheless, it will not seem underneath your VPN’s protocol choice tab when you have downloaded the Surfshark app straight from the VPN supplier’s web site. As an alternative, go to the Apple App Retailer and obtain the Dausos app, which is in beta.
I examined the brand new protocol in opposition to my preliminary unprotected connection and WireGuard, and located it labored effectively throughout the board for searching the Web and streaming on each Netflix and YouTube, so it appears the preliminary teething points have been ironed out.
Everytime you use a VPN, you might be introducing a intermediary between your machine and a web based service, and so it is best to count on a drop in speeds — though when your preliminary connection is comparatively quick, chances are you’ll not discover the distinction.

I discovered that Surfshark with WireGuard enabled lowered obtain speeds by 35.54% and add speeds by 6.30%. In contrast with Dausos, obtain speeds decreased by 38.25% and add speeds decreased by 4.88%.
Total, WireGuard nonetheless carried out higher for obtain speeds, whereas Dausos edged forward in add pace retention. (As connection and environmental components all differ, contemplate this solely a snapshot of what chances are you’ll count on — as your expertise might be fully completely different.)
Backside line
Dausos has potential, and given the marginal efficiency variations in comparison with WireGuard, I might advocate making an attempt it out, particularly since we’re more likely to see enhancements because the beta protocol continues to be refined. And if it entices you additional, it is good to know that it’s free and accessible to all Surfshark subscribers.
Will it ever grow to be open supply so the VPN and safety business can profit as an entire? When this query was posed to Kačiulis, he stated that it’s not potential through the early launch section — however Surfshark “see[s] the advantages of it and it is one thing we’re actively discussing.”
“We’ll preserve you up to date as we proceed to judge our open-source technique,” the engineer added.
