Speedify Encryption for Business
Speedify Encrypts All Traffic with AES-256 Across Every Internet Connection, on Every Device
Speedify encrypts all traffic end-to-end using DTLS 1.2 with AES-256-GCM on hardware-accelerated devices, and ChaCha20-Poly1305 on devices without AES hardware support.
Encryption is built into Speedify's channel bonding architecture: traffic is encrypted before it's split across your Wi-Fi, 4G/5G cellular, Ethernet, or Starlink connections, and remains encrypted through reassembly at the server. No unencrypted path exists at any point in the flow.
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
How Speedify's Encryption Works Across Bonded Internet Connections
Speedify encrypts traffic at the client before splitting it across available internet connections. Encrypted packets are distributed across Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections simultaneously, then reassembled at the Speedify server, still encrypted end-to-end throughout. No individual internet connection ever carries unencrypted traffic.
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 when bonding internet connections with different latency and loss characteristics, such as Starlink alongside 4G/5G cellular.
Encryption operates at the same layer as Speedify's bonding, failover, redundancy, and traffic prioritization, not as a separate overlay. This means security guarantees hold regardless of which internet connection Speedify is actively using at any moment, including during failover events or mid-session link changes.
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 encrypted tunnel, whether the endpoint is a workstation, a mobile device in the field, or a router at a branch office.
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 Business
See how Speedify's traffic distribution algorithms transport and protect internet traffic
Speedify's secure bonding algorithm weighs packet distribution decisions based on current path quality, unlike round-robin schemes that treat all paths equally. 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. Roll Speedify out across your entire device fleet with no custom configuration or dedicated hardware required.
- Independent security validation: Speedify is MASA (Mobile Application Security Assessment) certified through the App Defense Alliance, verified by regular independent third-party audits.
