We'd been running Cerberus FTP Server for a few years and it did the job well enough. Reliable, decent feature set, nothing to complain about really — until the renewal invoice arrived and the price had jumped dramatically. That's when we started looking around.
After evaluating a few options we landed on Syncplify Server! and have been running it for several months now. Here's an honest breakdown of how the two compare based on our actual experience.
Platform support
This was the first thing that surprised us. Cerberus is Windows only. Full stop. Syncplify runs on both Windows and Linux with identical feature parity across both — same scripting, same high availability setup, same security controls. For us that mattered because not everything in our environment runs Windows, and working around that with Cerberus was getting old.
Security architecture
Both products cover the basics well — SFTP, FTPS, granular access controls, Active Directory integration, two factor authentication. Where Syncplify genuinely pulled ahead for us was the built-in threat detection. The Protector system uses AI and heuristics to actively block suspicious activity rather than just logging it after the fact, which is a meaningful difference when you're transferring sensitive data regularly.
Syncplify also supports post-quantum encryption across all protocols, which isn't something we urgently needed today but felt like the right direction given where cryptographic standards are heading. Cerberus doesn't offer this.
Worth noting — Syncplify has maintained a zero CVE record, which given how often SFTP servers are targeted is something that carries real weight.
Pricing
This is where the difference becomes pretty significant. Cerberus starts at $1,599 per year on a subscription model, and several users have noted the pricing increased by over 400% in recent years. Syncplify uses a perpetual license model starting at $349 — you buy it once. For compliance heavy environments where you're planning to run this for years, that adds up to substantial savings over time.
Automation and scripting
Syncplify's SyncJS scripting through their AFT client is genuinely powerful once you get past the learning curve. We automated several file transfer workflows that we were handling manually before, which saved real time. Cerberus has an Event Manager that covers the basics but feels more limited in comparison.
Compliance
Both products support HIPAA compliant file transfer and GDPR requirements through audit logging and access controls. For regulated industries this is table stakes and both deliver. Syncplify's audit trails are detailed enough that we've had no issues demonstrating compliance during reviews.
Who should consider switching
If you're on Cerberus and happy with it, and Windows-only isn't a constraint, there's no urgent reason to move. But if you're running a mixed environment, care about where encryption standards are heading, or are feeling the pressure of annual subscription costs that keep climbing, Syncplify is worth evaluating seriously. The 15 day free trial covers the full feature set so there's not much risk in testing it properly.
