Speedify Fast, REliable and Secure internet connectivity for your business
Speedify Combines Internet Sources like 5G, 4G, Wi-Fi, & Satellite into one Secure, Encrypted Link
Speedify VPN encrypts all user traffic end-to-end using modern, standards‑based cryptography.
The primary transport security protocol is DTLS 1.2 (Datagram TLS over UDP), which ensures confidentiality and integrity even over unreliable links.
On devices that support hardware‑accelerated AES instructions (typical for modern desktops, laptops, servers), Speedify uses AES‑256‑GCM. This leverages built-in CPU instructions for efficiency, minimizing performance overhead while providing strong encryption.
On devices lacking AES hardware support (e.g. older mobile phones, embedded devices), Speedify automatically falls back to ChaCha20‑Poly1305. This cipher is optimized for software implementation and maintains high throughput and low latency, preserving security even on resource‑constrained devices.
Regardless of endpoint hardware capabilities, Speedify adapts to provide the most efficient strong encryption possible, mitigating performance‑vs‑security tradeoffs.
Speedify's Cryptographic Foundations and Protocols
Speedify Integration with Bonding & Multi-Path Infrastructure
Because Speedify is more than a typical VPN, it implements multi‑path channel‑bonding across all available Internet links (Wi‑Fi, Ethernet, 5G / 4G cellular, satellite, etc.). Encryption is deeply integrated into this architecture - traffic is first encrypted at the client, then split, distributed across links, and reassembled at the remote server.
The use of DTLS over UDP (rather than only TCP) helps preserve performance and error‑resilience: DTLS enables Speedify to manage packet loss, latency spikes, and unstable links more gracefully than traditional TLS over TCP, which is critical in multi‑path, variable‑quality scenarios.
This design allows encrypted tunneling to coexist with bonding, failover, redundancy, and traffic‑prioritization features. This is essential for real‑time collaboration, video conferencing, remote VPN access, or corporate data flows over mixed networks.
Speedify Cross‑Platform Coverage & Consistent Security
Speedify supports a wide variety of operating systems and device types, including Windows, macOS, Linux, iOS, Android, and embedded platforms (e.g. OpenWrt routers).
On all supported platforms, traffic is encapsulated in the same secure VPN tunnel model: independent of whether the endpoint is a high‑end workstation, a mobile device, or a router powering a home or branch office network.
Because encryption is built into the core of the architecture (not an optional add‑on), you don’t need specialized hardware or configuration. Deploying Speedify across a fleet, whether it's desktops, laptops, mobile field devices or remote routers, gives you uniform security guarantees.How Speedify Securely Provides Uninterrupted Internet for Your Organization
Unlike round-robin schemes that treat all paths equally, Speedify's bonding algorithm weighs packet distribution decisions based on current path quality. The Speedify system accounts for:
Latency variance: Packets are preferentially routed through lower-latency paths to minimize out-of-order delivery at the receiver, reducing reassembly overhead
Asymmetric capacity: Paths with higher throughput capacity receive proportionally more traffic to maximize aggregate utilization
Loss characteristics: Paths experiencing elevated packet loss receive reduced traffic allocation or redundant packet transmission depending on application requirements
Cost considerations: User-defined policies can restrict expensive interfaces (metered cellular) to overflow traffic or backup scenarios
This results in typical efficiency rates approaching 95% of theoretical aggregate capacity under optimal conditions.

Speedify scalable solutions for businesses of all sizes
Speedify's suite of networking tools can be deployed at any scale to deliver faster, more reliable internet to your entire office, campus, fleet, or user base.
For decision‑makers (CTOs, infrastructure managers, security officers), Speedify’s encryption delivers concrete value:
- Data confidentiality & compliance readiness: All Internet traffic (web, API calls, file transfers, remote work sessions) is encrypted end‑to-end, reducing risk of eavesdropping by ISPs, public Wi-Fi operators, or malicious actors. Useful for remote work, hybrid offices, or traveling employees.
- Unified security posture across distributed devices: Whether your team uses high‑end laptops, mobile devices in the field, or embedded routers at branch offices, encryption and bonding behave consistently. This reduces security management burden and risk of unprotected links.
- Performance‑aware security: By using AES with hardware acceleration or ChaCha20 for software‑only devices, Speedify minimizes encryption overhead, preserving bandwidth and reducing latency. This is important when working with real‑time media, large data transfers, or high‑performance applications.
- Resilience under unstable networks: Integration with multi‑link bonding and DTLS provides security without sacrificing availability, which is essential for remote teams operating over unreliable or variable‑quality networks (cellular, satellite, mixed connectivity).
- Simplified deployment at scale: Because Speedify doesn’t require custom configuration or dedicated hardware, you can roll it out across many devices quickly. This is useful in enterprise, remote‑first, or hybrid‑work environments to ensure consistent security everywhere.
For secure connectivity over public internet sources, such as Wi-Fi hotspots in restaurants, airports, etc.
For organizations that handle critical corporate data over distributed teams and remote sessions
For users whose activity involves accessing web resources that are unsafe from the point of view of privacy
For businesses in need of a VPN that doesn't slow down the connectivity just because it makes the connection safer and protects your privacy
