Your Agent's Approval Prompt Is Not a Security Boundary
A coding agent that asks 'run this command? [y/N]' feels safe. This month, the most-audited agent CLI shipped a fix for a bug where the command in that very prompt could be spoofed. Here's the defense-in-depth model that holds when the prompt doesn't — sandbox, allowlist, least privilege, in that order.

Zenity Raised $125M to Police a Billion Agents — What It Signals for Anyone Shipping One
The round is the news; the category is the point. Agent security just became a funded layer of the stack, and the reason is a number every founder is about to live inside: one autonomous agent per employee, then ten. Here's what the raise says you should already be doing.

August's AI Money Moved Down the Stack: $1.5B in One Day for Power, Photonic Silicon, and AI-vs-AI Security
July's funding wave bet on controlling the agents or owning a regulated vertical. On August 3, capital jumped one layer lower — to the reactors that power the models, the light-based chips meant to run them cheaper than a GPU, and the autonomous hackers that defend against other autonomous hackers. Here's the day's board and the one line each raise writes for a team of one.

How to Comply With EU AI Act Article 50: Label Your AI Chatbot and Sign AI-Generated Media (With Code)
The transparency rules went live on August 2, 2026. If your product talks to users or generates media, you now owe two things: a disclosure users can see, and a mark machines can read. Here's the disclosure snippet, the C2PA signing command, and the deadline you can still miss.

The EU's Chatbot-Disclosure Rule Takes Effect August 2: What a Solo Founder Actually Has to Ship
Article 50 of the EU AI Act is enforceable August 2, 2026. If you deploy a chatbot or an AI voice agent to EU users, the 'you're talking to an AI' duty lands on you — not your model vendor. Here's the short version, a checklist, and the disclosure to ship.

The EU AI Act's Content-Marking Rule Goes Live August 2 — What Article 50(2) Actually Requires
The Digital Omnibus delayed the Act's hardest rules to 2027. Article 50 was not one of them: if your product generates images, audio, video, or text, you must now mark it so a machine can detect it was AI-made. Here's the obligation, the December grace you might still have, and the one standard the Commission has already blessed.

YubiKey 5.8 Turns a Passkey Into a Veto: Hardware Approval Lands for AI-Agent Actions

Abstract Raised $25M to Unbundle the SIEM — and the Composable-vs-Monolithic Call Is One Every Lean Team Now Faces
Abstract's $25M round is small next to this month's mega-deals, but it's aimed at a decision that touches every builder who owns data: do you pour everything into one monolithic security platform that prices you by the gigabyte, or run detection in-stream and keep your data where it already lives? Here's the trade, and when each side wins.

Slopsquatting Grew Up: When Your Coding Agent Auto-Installs a Hallucinated Package, That's RCE
LLMs invent package names about one time in five, and 43% of those invented names are the same on every run — reproducible enough for an attacker to register. Give a coding agent permission to run `install` and that stops being a typo and becomes remote code execution on your machine.

Zero Trust for AI Agents: Why the New Frameworks Treat Your Agent as an Insider Threat
