Vigilance vs Sonatype Nexus
Sonatype Nexus. Holds your packages and blocks the ones it knows are bad before a build pulls them. Vigilance finds the update that gained a hidden power, before you install it.
The Catch Sonatype Nexus Cannot Make
Sonatype blocks packages it knows are bad. A brand-new attack is not 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. Sonatype 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 both. Sonatype keeps out every package it already knows is bad. Vigilance catches the one that has not made that list yet. See them side by side below.
Side by Side
| Question | Sonatype Nexus | Vigilance |
|---|---|---|
| Blocks a known bad package | Yes | No |
| Stores and serves your own packages | Yes | No |
| Covers software that never went through it | No | Yes |
| Spots a new file that can run other programs | No | Yes |
| Spots a file that can suddenly do more than before | No | Yes |
| Runs on a machine or field device after the package is through | No | Yes |
Which One Do You Need?
Use both. Sonatype blocks bad packages before they get in. Vigilance checks the files on the machine after the package is through it.
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.
