Menlo Security extended its Menlo Agent Runtime Security platform to protect AI assistants and coding agents from prompt injection and data exfiltration by sanitizing web traffic through a cloud proxy; Sweet Security announced Agentic AI Blocking to stop rogue agents in live production in real time; Acalvio launched Deception Guardrails in ShadowPlex, using honeytokens and decoy tools to flag jailbreaks and injection attempts against agents. AWS also opened a global red-teaming competition, 'AI Unlocked: Agents of Chaos,' running from August 31 with a $100,000 prize pool. The Menlo product in particular is a direct commercial answer to the UA-keyed injection payload found on tcrf.net the same week.
