Your favorite AI agents suggest artifacts for use. Aephix Sift provides cross-ecosystem intelligence on whether they are malicious or hallucinated, before any damage is done.
Much of the code shipping today was written by an assistant, and the import lines came with it. Nearly half of the dependency edits a coding agent makes introduce a package that was not there before.
Close to one in five package names suggested across sixteen models did not exist at all. Two in five of those invented names came back on every rerun, which is what makes registering one worth an attacker's time.
A self-spreading npm compromise reached 25,000 GitHub repositories in December 2025. The packages a team already depends on are the ones worth poisoning, so one release of a good package can be the problem.
By the time something is installed, the decision has already been made for you. Agents pick a known-vulnerable version more often than people do, so the moment that matters is the one before the download.
Sift names which one before anything is downloaded.
Caught the moment it is proposed, so it never reaches your machine.
Assistants invent names that sound right. Attackers register them and wait.
A name a character away from something your team already relies on.
Sift integrates wherever your team installs, imports and builds, fitting right into your daily workflows.
The answer arrives while your agent can still change its mind.
Works with the AI coding tools your team already has open.
One command for a package you are adding yourself.
The same answer on the machine that builds.
Three tiers. Looking one package up by hand stays free at Aephix Vantage.
Yes. Looking a package up by hand stays free at Aephix Vantage. Sift is the automation of that, and every paid tier opens with a free trial.
No. The trial runs without one, and it is time-limited rather than feature-limited, so you evaluate the real thing.
Individual and Team are monthly and cancel any time. Organization is an annual agreement.
Packages already known malicious, names your assistant invented that were never real, and near-copies of packages your team already trusts.
No. The packages you rely on keep working, and you hear from Sift when something is worth hearing about.
No. The answer is there before you would have noticed waiting for it.
No. Sift meets your team in the tools already open, so the workflow you have today is the workflow you keep.
No. Your code is yours. Sift never reads it, uploads it or indexes it.
Yes. Anything internal to your organisation stays internal, and your own record of what was checked stays on your machines.
