Questions
Is CybeDefend Open Source an alternative to Snyk?
Yes, for the scanning platform. It runs the scanners you choose, any tool that writes SARIF, and puts what they find in one deduplicated queue. It is free and runs on your servers.
Can I use it today?
The open source edition opens on December 4, 2026. Until then, CybeDefend Cloud is the same platform hosted by us, with our own scanners, and you can start a free trial today.
How does it compare with Snyk's agentic AppSec?
Evo Agentic AppSec, announced by Snyk on October 15, 2026, is a team of Snyk agents on Snyk's own engines, most of them in preview for selected customers. CybeDefend Open Source is open, free and yours to host, and your coding agents fix the vulnerabilities it finds.
Is Community really free?
Yes, forever. It runs on your servers with the scanners you choose, with no limit on projects or users, SSO included. We earn our living from the cloud, Enterprise and VibeDefend, and what is open stays open.
Can I host it myself?
Yes, that is the Community edition: the whole platform on your servers. If you prefer not to run it, Cloud is the same platform hosted by us, in Europe on SecNumCloud or in a US region.
When does it open, and what happens to my email?
On December 4, 2026. Your email goes into our CRM with the day you joined, and we write to you that day with the install link. Ask us and we delete it.
