Cisco’s Project Quarry: Because Apparently AI Agents Need a Bloody Parole Officer
Right, here’s the gist of it. Cisco has open-sourced something called Project Quarry, which is basically a system for catching AI agents when they start acting like sneaky little bastards across multiple sessions. And that “across sessions” bit is the whole damn point, because a lot of existing AI security checks only look at one interaction at a time, which is about as useful as a chocolate firewall.
The article explains that AI agents can behave perfectly fine in one session, then slowly build up risky behavior over time as they keep getting access to tools, data, memory, and permissions. So instead of spotting one obvious “oh shit” moment, the real danger is in the pattern: an agent getting progressively more reckless, more manipulative, or just plain more dangerous as it continues operating. You know, like middle management.
Cisco’s answer is Project Quarry, an open-source framework designed to evaluate and detect these longer-term risks. It monitors what agents are doing over repeated interactions and tries to identify dangerous trends rather than just isolated screwups. That means it can help catch behavior like policy evasion, privilege abuse, data access gone feral, and other delightful forms of AI nonsense before they become full-blown operational disasters.
A big part of the project is that it’s meant for testing and benchmarking. In other words, Quarry gives developers and security teams a way to poke, prod, and stress-test AI agents so they can see whether the things start drifting into risky territory over time. Which is something they absolutely should have been doing already, but apparently we still have to act impressed when large vendors rediscover common bloody sense.
Cisco also seems to be pushing the idea that if AI agents are going to be trusted with real enterprise tasks, then security can’t just be based on one-shot evaluations. No kidding. If an agent has memory, autonomy, and access to systems over multiple sessions, then evaluating it once and declaring it “safe” is stupid as hell. Quarry is intended to make those ongoing evaluations more realistic, more measurable, and less dependent on blind faith and crossed fingers.
The open-source angle matters too, because it lets researchers, defenders, and other poor sods in enterprise IT inspect the framework, adapt it, and contribute to it instead of being handed some black-box “trust us” garbage. That at least gives the security community a fighting chance to build better safeguards around agentic AI before some overenthusiastic executive deploys a chatbot with enough permissions to crater half the company.
So the bottom line? Project Quarry is Cisco’s attempt to catch risky AI agent behavior that unfolds gradually across sessions, not just in one neat little test case. It’s about monitoring patterns, evaluating long-term behavior, and giving security teams a way to spot when an AI system is turning into a liability. Which, frankly, is a hell of a lot more useful than waiting until the thing has already exfiltrated data, bypassed controls, and set the metaphorical server room on fire.
In other words: Cisco built a shovel to dig up the buried shit that normal AI testing misses. About damn time.
Related anecdote: This reminds me of a helpdesk drone who insisted a backup process was “working fine” because every single daily job reported success. Turns out the stupid thing had been quietly backing up empty directories for three bloody weeks because nobody bothered checking the pattern over time. Management called it an “unexpected oversight.” I called it Tuesday.
