Norton’s Data Channel Offload Finally Speeds Up OpenVPN Connections
Norton has enhanced the performance of OpenVPN by introducing Data Channel Offload technology, marking a significant improvement in connection speeds for users who rely on this widely used virtual private network protocol.
TL;DR
- Norton VPN adds DCO for faster speeds on Windows.
- Promising internal tests, but real-world results may vary.
- Competitive pricing and key security features included.
A New Chapter for VPN Performance on Windows
The world of VPN protocols has long been shaped by OpenVPN, celebrated for its security yet criticized for lagging behind newer competitors like WireGuard when it comes to speed. Now, in a surprising twist, Norton VPN has made a bold move: the exclusive deployment of the Data Channel Offload (DCO) module on its Windows application. This technical leap, while subtle in concept, might just transform the experience for users who value both privacy and performance.
The Technical Heart: What Is DCO?
Traditionally, OpenVPN handled all encryption operations in software—efficient but not always swift. The introduction of DCO changes this dynamic by shifting those heavy-lifting cryptographic tasks into the Windows system kernel. As explained by John Mah, technical director at Norton, “With Data Channel Offload, resource-intensive processes move directly to the operating system’s core. The aim: improved efficiency without sacrificing confidentiality or security.” The upshot? Users can expect noticeably faster connections, reduced latency, and optimized handling of demanding activities like 4K streaming or large file transfers.
Benchmarks and Caveats: Promises Meet Reality
According to internal testing data shared by Norton VPN, enabling DCO effectively doubled connection speeds under Windows and cut latency by around 15%. Himmat Bains, product lead at Norton VPN, notes that this brings “proven security together with unprecedented everyday comfort.” Yet a word of caution remains warranted. These promising figures originate from controlled environments; actual outcomes may shift based on your distance to servers or local network conditions. For context, earlier independent testing placed Norton’s OpenVPN speeds at a respectable 275 Mbps—so if these improvements hold true in wider use, surpassing 500 Mbps could become standard. That would put Norton in direct contention with top providers such as ExpressVPN, Surfshark, and Private Internet Access.
Pushing Forward with Price and Features
For those seeking value alongside technical prowess, Norton offers an aggressive subscription rate: just $2.50 per month (with annual billing), backed by a 60-day satisfaction guarantee and even a free trial. The plan encompasses:
- Protection for up to five devices
- Key security functions (kill switch, double VPN, IP rotation)
- High throughput across both OpenVPN and WireGuard protocols
Existing customers need only update their Windows app (version 25.8 or above) to enjoy DCO’s advantages right away.
In sum, this mix of technological innovation and strategic pricing could mark a turning point for Norton VPN within an increasingly crowded market—though whether it lives up to user expectations over time remains the ultimate test.
