In 2025, Surfshark shifted its focus from product consolidation to infrastructure depth, refining the underlying systems that support its cybersecurity and privacy services. This move came amid a year defined by the accelerating adoption of Generative AI technologies and a sharp rise in global data breaches, conditions that demanded more resilient, adaptive, and transparent VPN network architecture.

For Surfshark, the emphasis on technical groundwork reflected a broader effort to strengthen the performance, reliability, and trustworthiness of its platform in an increasingly volatile digital environment.

According to Vytautas Kaziukonis, CEO at Surfshark, the company’s primary goal for the year was to "significantly raise the bar for VPN performance." While the industry often focuses on flashy features, Surfshark’s 2025 strategy was rooted in stability and speed, ensuring that as internet usage grows more demanding, the VPN layer remains invisible.

The year of Everlink and 100Gbps

The most significant technical leap of 2025 was the introduction of Everlink, Surfshark’s patented self-healing VPN infrastructure, which keeps connections stable even when individual servers fail or go offline.

As users increasingly rely on mobile devices that constantly switch between Wi‑Fi and cellular data, maintaining a secure tunnel can be difficult because brief drops or handovers can momentarily expose traffic or force a full reconnection.

"In 2025, Surfshark... launched Everlink, an industry-first patented technology designed to deliver greater VPN connection stability," Kaziukonis explained. He described the feature as a "supporting, self-healing infrastructure" capable of seamlessly recovering dropped connections.

For the end user, this means fewer interruptions when moving from the office to the train, closing a common vulnerability gap where data can leak during a handover.

Alongside stability came raw power. To match the rollout of gigabit fiber in homes globally, Surfshark upgraded its backend hardware. "We deployed our first-ever 100Gbps bandwidth servers in response to the growing demand for higher bandwidth," Kaziukonis noted, aiming to ensure the VPN "won’t become a bottleneck."

This hardware upgrade was paired with software optimization in the form of "FastTrack." Built on Surfshark’s existing Nexus infrastructure, this technology optimizes traffic paths using a network of servers rather than a single tunnel.

According to Kaziukonis, this approach is capable of "boosting internet speeds by up to 70%," a substantial claim that positions them aggressively against speed-focused rivals like ExpressVPN.
