Point to point transfers; AES-128/256 encrypted, no files stored in the cloud and no 24/7 listening network services.

Accsyn allows you to send an invite to an E-mail address and lets the receiver choose a password when registering. Never again will you have FTP logins and passwords floating around in forwarded E-mails.

The Accsyn file server party is only active during transfers and only accepts connections from the remote WAN clients IP - no listening network services vulnerable for attacks.

You decide which files to share/send; clients cannot browse and copy files from your servers.

All communications utilize SSL (Secure Sockets Layer).

Accsyn Security Whitepaper

secure AccSyn img

Accsyn is a MFT(Managed File Transfer) software that replaces in-house solutions such as (S)FTP, HTTP(S), RSync. We focus on high security, ease of use and providing our clients a powerful CLI/API tool set allowing integration of file transfers into an existing workflow.

Our accelerated P2P file transmission algorithm enables Accsyn to send files 10-20 times faster than traditional FTP/RSync protocols.

Accsyn will provide you with a manageable file transfer queue that put you in total control, with its own settings like priority and bandwidth limits. Allowing you to reschedule, abort or add files for transfer at any time, either within desktop app or our mobile friendly web UI.

Accsyn lets you share a directory on your server, optionally bound to a queue, with ACLs defining which users have access to subfolders - a collaborative share.

After a brief period of testing Accsyn quickly became our goto solution for pretty much all of our file transfers. Previously we relied on a mixed bag of solutions and fragile duct taped hacks. Today we exclusively use Accsyn for transferring media from on-set to our NAS. With Accsyn we cut delivery time in more than half, we took security to another level, we got an easy web portal for administering it and with the brilliant central queuing system we're in absolute and total control. On top of that it's approved by HBO, which makes our lives very easy. By using the Python API our pipeline developer have tightly integrated Accsyn into our VFX pipeline, making it the backbone for all transfers to and from artists around the globe. Working remotely have never been so easy and I don't think we have had one corrupt frame delivered to us since we went from an FTP solution to Accsyn. The built in verification and the highly resilience nature of it not only saves us time during transfer but also in QC and administration. It has gone so far that if we suggest some other method of delivery to our clients they have started to ask for Accsyn instead, for example our editors can sync material from the Avid Nexis down to their setup at home or when out traveling - well tested in northern Sweden, in Italy, in UK and in the USA. Today Accsyn is such a crucial piece of our pipeline and workflows that I have a hard time seeing how we could do any production without it. I know it sounds like I'm trying to sell you a car here, but it's honestly that good and I truly love it.

We are using Accsyn to keep our offices in synk, transporting assets for cloud rendering and ingestion of outsource material. The self-explanatory Python API has made integration easy and painless for us, and the overview given by desktop app and web interface helps us track down all ongoing transfers at any moment.

Filmgate early saw the need to work with global assets, integrated into their pipeline utilising the full bandwidth of the Internet connection. This in turn contributed to a 50% financial growth without the need of relocating personnel to the Gothenburg headquarters. Accsyn has been production proved since 2015 hauling media between multiple locations on all continents enabling effective outsourcing and employment at satellite offices. Movies like the Oscar nominated “Never Look Away”(2018), Rambo(2019), Bamse (2018) were possible to complete on time and budget thanks to the stability and reliability of Accsyn.
