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?

The corporate says that whereas many protocols utilized by VPN networks at the moment weren’t initially designed for client use — and have been as an alternative merely tailored to be match for objective — Dausos has been particularly constructed for this activity.
What makes it completely different?
In line with Surfshark, Dausos makes use of AEGIS-256X2 as an alternative of the extensively used AES-GCM, however the important thing distinction is that it gives a separate, devoted visitors tunnel for every consumer. Usually, you’ll 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 threat of visitors contamination or publicity.
In a Reddit threadKarolis Kačiulis, Main System Engineer at Surfshark, mentioned:
“When customers share a tunnel, one consumer’s visitors load can intrude with one other’s, that 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 downside goes away.”

Surfshark says this protocol could 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 might also assist defend towards future assaults as a post-quantum answer.
Backing Dausos claims
Introducing any new main encryption expertise or protocol all the time 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 replicate a secure and resilient platform,” the assessment (.PDF) reads. “The Surfshark group demonstrated a big dedication to safety by remediating the vast majority of the findings instantly following the testing section.”
This doesn’t suggest it has all been truthful winds, nonetheless, as upon launch, some testers found Dausos didn’t carry out properly with residential connections. Nonetheless, Surfshark quickly developed and deployed a repair, which seems to have resolved the difficulty.
Set up, testing, and remaining ideas
In the meanwhile, Dausos is barely obtainable 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. Nevertheless, it will not seem beneath 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 towards my preliminary unprotected connection and WireGuard, and located it labored properly throughout the board for looking 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’re introducing a intermediary between your system and an internet service, and so you must anticipate a drop in speeds — though when your preliminary connection is comparatively quick, you could 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%.
General, WireGuard nonetheless carried out higher for obtain speeds, whereas Dausos edged forward in add pace retention. (As connection and environmental components all fluctuate, take into account this solely a snapshot of what you could anticipate — as your expertise might be utterly completely different.)
Backside line
Dausos has potential, and given the marginal efficiency variations in comparison with WireGuard, I would suggest 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 obtainable to all Surfshark subscribers.
Will it ever develop into open supply so the VPN and safety business can profit as an entire? When this query was posed to Kačiulis, he mentioned that it’s not attainable throughout 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.
