The integration lets users block malicious and unwanted sites while keeping Dausos' post-quantum encryption and its speed advantage

Surfshark has brought its web content blocker to Dausos, the proprietary VPN protocol it built in-house, meaning users of one of the best VPN services can now filter unwanted websites without switching away from the company's fastest, most future-proof connection option.
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 VPNSurfshark 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.
The web content blocker is a filtering tool designed to keep an entire household safer without watching what anyone does online.
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.

While connected through the Dausos protocol, open the Surfshark app settings and toggle on the web content blocker.
From there, you choose which categories to restrict, and two-factor authentication can lock the configuration so only an approved admin can change it.
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.
