Vigilance vs Snyk
Snyk finds a package with a bug someone already named. Vigilance finds the update that gained a hidden power, before you install it.
The Catch Snyk Cannot Make
Snyk checks your packages against a list of known bugs. A brand-new attack has no entry on that list yet. Vigilance keeps no list. It compares the version you trust with the version you install. It reports any file that can suddenly do more.
A real one: axios, March 2026
axios is one of the most-installed packages on the internet. In release 1.14.1, its package.json gained a hidden install step. That step pulls down a remote-control program. Snyk had nothing to flag, because no CVE existed. One command sees it:
vigi diff --old ./axios-1.14.0 --new ./axios-1.14.1
HEADS UP. 1 file changed. package.json can now run a hidden helper on install and reach the network.
Run them together. Snyk clears the bugs with a name. Vigilance catches the change nobody named yet. The two sit side by side below.
Side by Side
| Question | Snyk | Vigilance |
|---|---|---|
| Finds a part with a known bug | Yes | No |
| Opens a pull request to fix it | Yes | No |
| Finds a mistake in your own code | Yes | No |
| Spots a new file that can run other programs | No | Yes |

Which One Do You Need?
Use both. Snyk finds what is already known to be bad. Vigilance finds what is new.
Known Risk versus New Risk
A bug or a bad package someone already reported, with a name and a number. Most tools work here.
A file that gained a capability it never had, that no report covers yet. Vigilance works here.
