Surfshark Launches Patented Everlink Technology for VPN Stability
New self-healing infrastructure prevents connection drops and protects user privacy during server maintenance.

KEY TAKEAWAYS
- Surfshark introduces Everlink, a patented technology that automatically recovers dropped VPN connections without user intervention.
- The system creates a dual-layer connection structure where users connect to both VPN and Everlink infrastructure simultaneously.
- Everlink maintains stable connections during server maintenance by automatically routing traffic to nearby servers.
- The technology addresses privacy risks associated with unstable VPN connections that can expose user IP addresses.
- Everlink is enabled by default on WireGuard protocol across iOS, macOS, Windows, Android, and Linux platforms.
Surfshark has announced the launch of Everlink, a new patented technology designed to address one of the most persistent challenges in VPN services: connection stability. The cybersecurity company claims this industry-first solution represents a significant advancement in maintaining secure, uninterrupted VPN connections for users worldwide.
How Everlink Technology Works
The Everlink system operates as what Surfshark calls a “self-healing” infrastructure. When users connect to Surfshark’s VPN service, they simultaneously establish connections to both the standard VPN infrastructure and the Everlink network. This dual-connection approach creates a backup system that activates instantly when the primary VPN connection experiences disruptions.
“Think of a well-known VPN comparison to an encrypted tunnel — if the VPN is a tunnel which secures your traffic, imagine Surfshark Everlink as another one which secures that VPN tunnel,” explains Donatas Budvytis, Chief Technology Officer at Surfshark. The system automatically reconfigures VPN tunnels without requiring users to disconnect and reconnect manually.
According to Surfshark’s documentation, the technology is built on two patents: US11190491B1 for maintaining resilient VPN connections and US20240080302A1 for VPN server clustering.
Addressing Connection Stability Challenges
Budvytis emphasizes that connection stability represents the most critical metric for VPN performance. “While other shiny metrics, such as the number of servers might seem important, connection stability is something that truly makes the difference to the user experience,” he states.
The technology specifically addresses scenarios where server maintenance could disrupt user connections. Everlink automatically routes traffic to the nearest available server when maintenance requires shutting down specific servers, maintaining uninterrupted service without affecting user experience.
Privacy and Security Implications
Beyond convenience, Everlink addresses significant privacy concerns associated with unstable VPN connections. When VPN connections drop unexpectedly, users’ real IP addresses can become exposed, creating potential security vulnerabilities.
“At best, unstable VPN connection is simply annoying, however, it can also be risky, as unstable connection can lead to exposed user data,” Budvytis explains. He highlights particular risks for journalists, activists, whistleblowers, and privacy-conscious users who depend on consistent IP address masking.
Comparison with Kill Switch Technology
Surfshark distinguishes Everlink from the industry-standard Kill Switch feature. While Kill Switch terminates internet connections entirely when VPN failures occur, Everlink maintains connectivity by switching to backup infrastructure.
“The main difference between Kill Switch and Surfshark Everlink is that the Kill Switch does exactly what it says on the tin — kills your connection in case of a server failure,” Budvytis notes. He explains that while Kill Switch provides security through disconnection, Everlink aims to keep users both connected and protected simultaneously.
Users retain the option to enable Kill Switch alongside Everlink, providing multiple layers of protection based on individual preferences and security requirements.
Platform Availability and Implementation
Everlink technology is enabled by default on the WireGuard protocol across all major platforms, including iOS, macOS, Windows, Android, and Linux. This broad compatibility means users across different operating systems can access the enhanced connection stability without additional configuration.
The launch represents part of Surfshark’s broader innovation strategy. The company recently introduced a free DNS service as an alternative to default DNS providers, demonstrating continued expansion beyond traditional VPN services.
Surfshark operates as part of a cybersecurity suite that includes independently audited VPN services, certified antivirus software, private search tools, and data leak monitoring systems. The company received recognition as Tech Advisor’s Editor’s Choice for 2024, according to their annual wrap-up report.
The Everlink launch reflects growing industry focus on connection reliability as VPN adoption increases globally. By addressing fundamental infrastructure challenges, Surfshark positions itself to compete on technical innovation rather than traditional metrics like server count or connection speeds.
