The #1 Seal Security alternative

Avoid losing control of your builds, thanks to Echo

Seal rewrites your build under its own control, while Echo simply ensures your package manager is pulling fully vetted, patched libraries and containers - nothing else changes.

Why teams like yours prefer Echo

“With Echo, we’re saving more than 200 hours of developer time per release.”

Dan Garcia,

CISO

"It's the same way that you work today – just without having to worry about vulnerabilities."

Mor Paz

R&D Director

“With Echo, zero vulnerabilities showed up, everything was compliant, and the auditor was super satisfied. Just a smooth ride.”

Lior Chen,

Deputy CTO at Varonis

“To look at the scans results and see that there were no CVEs in the image being used… That in and of itself was game-changing.”

Brian Kerr,

CISO

“It’s pretty accepted that CVEs are going to show up in our dashboards. So to see a product prevent them altogether - it's huge.”

Prasant Siinghal,

DevOps Lead

"With Echo, it’s literally a flip in version or name, and we see 90% fewer vulnerabilities. The barrier to implementation is low, and the value is immediate."

Chris Long,

Director of IT & Security

More reasons why teams pick Echo

7-day fixes, zero exceptions
Critical and high CVEs are remediated in 7 days across everything Echo covers – no waiting on whether your library made Seal's list.
Millions of vetted libraries
Echo checks and patches millions of libraries across every ecosystem, not just the subset Seal has chosen to cover.
Zero build rewrites
Echo doesn't touch your build process, while Seal's implementation rewrites in-build package files under its own control, not yours.
