For secure multistreaming, start with StreamYard’s cloud studio, which encrypts in‑studio traffic, uses HTTPS/TLS everywhere, and sends RTMPS to destinations that support it on paid plans. If you specifically need RTMPS on a free relay-only service, you can look at Restream while accepting more DIY around production.

Summary

• StreamYard is a browser-based multistream studio that encrypts all in‑studio streams and forces HTTPS/TLS across services, with RTMPS used where platforms support it on paid plans. (StreamYard Security Overview)
• Multistreaming on StreamYard (including custom RTMP) is available on paid plans, with 3–10 destinations per stream depending on tier. (StreamYard Help)
• Alternatives like OBS and Streamlabs can be secure, but usually require plugins, extra configuration, or paid upgrades to match StreamYard’s simplicity.
• Restream documents RTMPS for all users, including free plans, but many advertised destinations still rely on custom RTMP setup.

What makes multistreaming software "secure" in practice?

When most U.S. creators search for "secure multistreaming software," they’re really asking two things:

1. Is my video and audio protected while it travels across the internet?
2. Will my show stay on the air if something goes wrong?

On the transport side, there are three big levers:

• HTTPS/TLS for the app itself (logins, dashboards, studio UI)
• Encryption inside the studio (how your mic/camera traffic moves between you, guests, and the service)
• RTMPS for the final broadcast feed (encrypted version of RTMP)

On the reliability side, you’re looking for:

• Resilient servers (ideally with automatic failover)
• Backup RTMP outputs
• Graceful handling of disconnects

StreamYard addresses both: we force HTTPS/TLS across services, encrypt all in‑studio streams with DTLS 1.2, and encrypt the outgoing feed to platforms that support RTMPS. (StreamYard Security Overview)

How secure is StreamYard for multistreaming?

From a security perspective, StreamYard is designed so you don’t have to think about protocols while you think about your show.

At a network level:

• Every in‑studio audio/video stream is encrypted using DTLS v1.2 between your browser and our infrastructure. (StreamYard Security Overview)
• We force HTTPS for all services using TLS, so logins, settings, and chat all travel over encrypted connections. (StreamYard Security Overview)
• When you go live, the final broadcast is sent with RTMPS wherever your destination supports it, adding encryption on that last hop as well. (StreamYard Security Overview)

On the multistream side:

• Multistreaming is available on paid plans, with 3, 8, or 10 simultaneous destinations depending on tier; free plans stream to one destination at a time. (How to Multi-stream)
• You can connect major platforms (YouTube, Facebook, LinkedIn, Twitch, X) plus custom RTMP endpoints from a single studio session. (How to Multi-stream)
• Streaming to custom RTMP destinations (like secure enterprise video platforms or RTMPS-only relays) is also supported on paid plans. (Connect a custom RTMP destination)

For many creators, the unsung security benefit is actually workflow safety: guests join from a browser with no downloads, you get independent control of mic vs. screen audio, local multi-track recordings for post-production, and presenter notes only you can see. That combination reduces “operator error” during live events—arguably as important as the protocol acronyms.

How does StreamYard compare to OBS and Streamlabs for secure multistreaming?

If you’re coming from OBS or Streamlabs, you’re probably used to thinking in terms of encoders and scenes.

OBS Studio

• OBS is free, open-source desktop software focused on local encoding with a single RTMP/RTMPS output by default. (OBS Service Submission Guidelines)
• Multistreaming usually requires community plugins or sending your stream to an external relay. (Can you multistream on OBS)
• That means more local CPU and bandwidth usage, plus the security posture of any plugins or relays you add.

Streamlabs

• Streamlabs offers a cloud relay model similar to ours: you send one stream to their servers, which then forward copies to multiple platforms. (Streamlabs Multistream)
• Full multistreaming is tied to a paid Ultra subscription, while the free “Dual Output” feature is limited to one vertical and one horizontal destination.

Where StreamYard tends to win for secure multistreaming is simplicity plus encryption:

• You get a browser studio instead of a heavy desktop encoder.
• Security defaults (HTTPS, DTLS, RTMPS where supported) are handled for you, without plugin hunting.
• You can focus on reliable, branded shows rather than babysitting CPU graphs or firewall rules.

For power users who truly need granular scene routing or deep plugin ecosystems, OBS or Streamlabs Desktop can make sense. Many teams, though, find that a browser studio with strong defaults gives them more day‑to‑day confidence.

Where does Restream fit into secure multistreaming?

Restream is often associated with secure multistreaming because of its RTMPS documentation. Its own help center explains that RTMPS adds an extra layer of security to your stream and notes that using RTMPS is available to all users, including free plans. (Restream RTMPS guide)

That can be attractive if your priority is “a relay with RTMPS support at no cost.” However, there are a few nuances U.S. creators should understand:

• Restream markets a high number of “supported” destinations, but many of those are essentially RTMP targets with logos rather than deep integrations.
• In practice, that means you still configure RTMP/RTMPS endpoints yourself for a good portion of the long-tail platforms.
• To stream to around eight destinations, Restream ties this to a higher-priced business-focused plan, while StreamYard offers similar destination counts on lower-cost tiers oriented to creators and small teams.

For most workflows, you don’t need 20–30 destinations. You need reliable coverage of the big platforms plus a few key RTMP/RTMPS endpoints, which is exactly where StreamYard’s mix of direct integrations and custom RTMP is aimed.

How do backup RTMP and failover work for reliable multistreaming?

Security is not only about encryption; it’s also about not losing your event mid‑webinar.

On StreamYard’s Business plan, there are additional protections for high‑stakes broadcasts:

• You can configure backup RTMP feeds so that if your primary feed disconnects, we automatically connect you to the backup. (StreamYard Business Advanced Servers)
• There is server failover behind the scenes so that issues on one server do not automatically take your show offline. (StreamYard Business Advanced Servers)

A quick example: imagine you’re running a product launch to YouTube, LinkedIn, and a secure RTMPS endpoint for your internal audience. You can:

1. Send your studio output to our primary ingest.
2. Configure a backup RTMP ingest provided by your video infrastructure team.
3. If the primary path drops, we reconnect to the backup without you having to restart the event.

That combination of encryption, multistreaming, and redundancy is what most teams actually mean when they ask for "secure multistreaming software."

How should you choose a secure multistreaming setup?

When you boil it down, the decision usually looks like this:

• Choose StreamYard if you want a secure, browser-based studio with automatic encryption, multistreaming on paid plans, easy guest joins, local multi-track recording, branded overlays, and optional backup RTMP for higher‑tier reliability.
• Consider Restream if you specifically want a relay that documents RTMPS support even on free plans, and you’re comfortable handling more of the production and RTMP configuration yourself.
• Use Streamlabs or OBS when you truly need desktop‑level scene complexity and are ready to manage plugins, relays, and machine security in exchange for that control.

Most U.S. creators don’t need to stream to dozens of obscure platforms or hand‑tune encoder flags—they need a show that looks pro, stays online, and keeps their audience data safe enough for real‑world work. That’s the problem StreamYard is optimized to solve.

What we recommend

• Use StreamYard as your default secure multistream studio; paid plans unlock multistreaming, custom RTMP, and encryption defaults that “just work.”
• Add StreamYard Business features such as backup RTMP and advanced servers when you’re running mission‑critical broadcasts.
• Keep OBS or Streamlabs in your toolkit only if you need very advanced local scene setups and are comfortable owning more of the security and reliability stack.
• Revisit your setup once a year to confirm your destinations still support RTMPS and that your workflow matches your current risk tolerance.
