About
Most dependency scanners tell you which of your packages have known vulnerabilities. Socket's argument is that the more dangerous case is a package that is behaving badly right now and has no CVE attached — a maintainer account taken over, an install script that phones home, a name one character away from something you meant to type. Socket analyses package behaviour rather than only its published vulnerability record, across six programming languages, and says it detects and blocks over 100 software supply chain attacks every week.
Feross Aboukhadijeh, a Stanford lecturer who wrote several widely-downloaded JavaScript packages, founded the company. In October 2024 it announced a $40 million Series B led by Abstract Ventures with Elad Gil and Andreessen Horowitz, bringing total funding to $65 million; the angel list included Bret Taylor, Phil Venables, Scott Johnston, Christina Cacioppo, Ann Mather and Tobias Lutke. It reports protecting more than 7,500 organisations and 300,000 GitHub repositories.
Ahmad Nassri is Socket's chief technology officer. He was CTO of npm through its 2020 acquisition by GitHub, VP of engineering at Kong and chief architect at TELUS Digital, and led engineering at Mashape when he spoke at TechTO in 2015.

Quick answers
What does Socket do?
It secures the software supply chain by analysing how open-source packages behave — install scripts, network calls, obfuscated code — rather than only checking them against known vulnerability lists, and blocking the bad ones before they land in a codebase.
Who founded Socket and how much has it raised?
Feross Aboukhadijeh, a Stanford lecturer and open-source maintainer. It has raised $65 million in total, including a $40 million Series B in October 2024 led by Abstract Ventures.
Did Socket take the TechTO stage?
No. Ahmad Nassri, Socket's CTO, spoke at TechTO in 2015 — but he was leading engineering at Mashape then, the API marketplace that became Kong.
