What we add

Graph

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

Articles mentioning this entity 21 Open source projects 16 Organizations tagged 84 Organizations AgilePQ, American Registry for Internet Numbers, Aonta Technologies, AppViewX, ARIN, AS53616, Asia Pacific Network Information Centre, Atos, AUTOCRYPT, Comodo, Confiar Digital, connect2, Crypta Labs, Crypteo, CryptoLab, Cryptomage, CryptoNext Security, Cryptosoft, Cybersecurity e Data Protection per aziende Related terms Related terms (co-occurring topics)

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Public Key Infrastructure for a real decision: a shortlist, a vendor comparison, a purchase. "Public Key Infrastructure makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
