Until now, running the blocker alongside an active VPN connection meant sticking to WireGuard, since that was the protocol it supported. Bringing the tool to Dausos closes that gap, so households no longer have to trade the protocol's advantages for a safer browsing experience. Dausos uses a hybrid post-quantum secure key exchange and delivers up to 30% faster speeds than other industry-standard protocols. Pairing that with category-based filtering means you get speed, privacy, and content protection in a single connection rather than picking two of the three.

Surfshark the best cheap VPN Surfshark is a fast, easy-to-use VPN that seriously beats the competition when it comes to subscription pricing. Its two-year Starter plan works out at $2.49 a month (plus tax), but we think Surfshark One is the best value plan as it adds an antivirus, data breach monitor, and alternative ID tool starting from the equivalent of $2.79 a month. View Deal What's new, and why it helps The web content blocker is a filtering tool designed to keep an entire household safer without watching what anyone does online.

Unlike traditional parental-control apps, it is built to control access
rather than log every click, and Surfshark says it does not record individual browsing history. You can read more on how it differs from conventional parental controls in our earlier coverage.

In practice, you pick from a set of predefined categories such as adult websites, gambling, profanity, phishing, and malware, and any site that falls under them is blocked. According to Surfshark's Karolis Kaciulis, the aim is to protect people from threats "caused by curiosity or carelessness" and to cut their exposure to a growing wave of online scams.

The headline benefit of the Dausos integration is that you keep the
protocol's performance. Surfshark says users can retain up to 30% higher speeds and ultra-low latency while filtering runs, all while staying fully post-quantum secure. (Image credit: Future) NEW : Leave No Trace A weekly newsletter on digital privacy and online surveillance.

From there, you choose which categories to restrict, and two-factor authentication can lock the configuration so only an approved admin can
change it.

The rollout is currently limited to Surfshark One and Surfshark One+ subscribers running the latest app version on macOS. If you're on the cheaper Starter plan or a different platform, you'll need to wait or upgrade. A quick look at the Dausos protocol (Image credit: Surfshark) Dausos, which means "paradise" in Lithuanian, is Surfshark's first homegrown protocol, and it takes a different approach to most rivals.

Rather than pooling everyone's traffic through a single tunnel, it gives each user session its own dedicated, private data tunnel, which is where much of its speed advantage comes from.

On security, it uses a hybrid ML-KEM and X25519 key exchange plus an ML-DSA self-signed root certificate system to guard against future quantum threats, along with post-compromise security, port randomization, and AEGIS-256X2 encryption.

It has also been independently audited by Cure53, and a recent update
improved its behaviour on the locked-down networks that often trip up VPNs on school and office firewalls.
