Nebula Security
Trident
Read away from the record, per side. A side with nothing here is a side where nothing answered — the space is left empty rather than filled from the other one.
Nebula Security
NebuSec builds Nebu, an AI security platform for continuous code and cloud protection, backed by researchers who find zero-days in Chrome and Linux.
The title and description the site itself served, answering 200. Not a cached copy and not the company's directory entry — what was live when we asked.
Trident
Trident is an AI-powered security platform for continuous web and API penetration testing and cloud attack-path analysis across AWS, Azure, and GCP.
The title and description the site itself served, answering 200. Not a cached copy and not the company's directory entry — what was live when we asked.
Counted only where a thread links to this company's own site, announces it by name on that forum, or names it beside its own Y Combinator batch. A thread whose title merely carries the words is not counted — a name is not an identifier. More may exist than the one page of results read here. Hacker News is not us, and nothing above is our opinion of the company.
