If I were in charge of an org's cybersecurity I would have AI agents continually trying to attack the systems 24/7 and inform me of successful exploits; it would suck if the major model providers block this type of usage.

Shameless plug: We're building this. Our goal is to provide AI pentesting agents that run continuously, because the reality is that companies (eg: those doing SOC 2) typically get a point-in-time pentest once a year while furiously shipping code via Cursor/Claude Code and changing infrastructure daily.

I like how Terence Tao framed this [0]: blue teams (builders aka 'vibe-coders') and red teams (attackers) are dual to each other. AI is often better suited for the red team role, critiquing, probing, and surfacing weaknesses, rather than just generating code (In this case, I feel hallucinations are more of a feature than a bug).

We have an early version and are looking for companies to try it out. If you'd like to chat, I'm at varun@keygraph.io.

2nd employee at Semantics3 here. Considering all the AI available today I think things like product disambiguation becomes wayyy easier. We were trying many tricks and heuristics to identify the same products across sites.

Care to explain what IB, PE, and HF mean?
netvarun · 7 months ago
I think they refer to: IB - investment banking PE - private equity HF - hedge funds or High Frequency trading (?)

Tangent: Did Windsurf actually get acquired by OpenAI? I would have imagined some sort of announcement from OpenAI at the very least? Bloomberg was the one to break that news too, but haven't seen any follow up.

Does anyone have insight into Neon's financials - specifically their revenue, COGS, and gross margins? I'm trying to understand what made Databricks value them at $1B. Was it strong unit economics, rapid growth, or mostly strategic/tech value?

Also an Earthly casualty here. Now having to look at Dagger.
netvarun · 9 months ago
Dagger (https://dagger.io) recently seems to have reinvented/rebranded itself as some llm agent platform.

@dang: The original URL (from Step Security, the company that discovered this flaw) is a better source for this:
