Hi all, Gadi here (CEO of Cymmetria). We are here on Hacker News and would be happy to answer any questions, technical or otherwise, and discuss.
Nothing much to add except good luck Gadi. There's always going to be bad actors in this world and the more techniques the better. (Slight disclaimer: I know Gadi well from the anti-spam world)
Cymmetria (YC S15) Uses Virtual Machines to Decoy and Detect Hackers

#22This is a solid idea with a great team behind it. The challenge with this kind of product is to make it easy to deploy while delivering actual value to users, and looks like they've figured that out. (It was great meeting Gadi in the speakers lounge at a conference in Hamburg and doing the YC sales pitch last year.)

It's a fun twist on that conventional bit of security technology, though* . What I'm unsure of is whether these decoy-type products really provide much value beyond alert triage. Even if we're charitable and assume they don't introduce new false positives into the system, all the old false positives remain. * Disclaimer: I manage one of those nine-figure security products you mention.

The system will not catch everything in any way - but what it does catch has no false positives by definition. We're very happy to demonstrate live the value proposition and how alerting is one aspect of what we do.

This is why I'm unsure of the value. And to be clear, by "unsure of the value" I don't mean "unsure whether it has any value." It certainly has value. I'm just not sure how much, as, say, a dollar figure.
"No false positives" is fine marketing, but in practice you aren't replacing anyone's firewalls, endpoint agents, sandboxes, SIEMs, etc. All those false positives will still be there, along with many legitimate detections your system never sees.
If money were no object, then absolutely I'd buy. But given that money is usually a factor, that you're limited to detection, that you're only effective in scenarios where attackers touch your decoy systems, and that you're competing for dollars against products that detect more, detect it sooner, and often prevent it automatically, I don't know.

How does it work, really? Do you provide a plausible-looking virtualized fake enterprise network that will look like a real thing to outsiders? Or do you put honeypot servers alongside other production servers, running whatever applications are really being used by the company? Do you intend to protect against inside threats as well?
Each decoy is configured to look exactly the way that makes sense for the network it's in. An example is a git server with interesting code or an employees pc that shares files that are crafted to draw attackers to that decoy. The decoys themselves can be placed within the customers network or hosted in the cloud by us. The real trick is "breadcrumbs" which is specific data/files that you can place on the real machin…
If the breadcrumbs are realistic then you will end up having employees mistake them for real data, and the employees being mistaken for an attack, no?
If the decoys are realistic then they will have realistic behaviour, for instance, doing an auto update. Now, let's say I'm a malicious actor on the network, and I fake the auto-update server so the patches downloaded are backdoored. Its very hard to detect this attack. Any network has a lot of broadcast traffic between all the nodes - if a decoy doesn't transmit any then it would be a suspicious, and if it does, then its hard work for a decoy to separate the real traffic from a potential attack.

Thanks for the reply. So I am unclear on the meaning of "attack". Is this more than a series of pings, or an attempt to do a pexec or remote viewing of the event log? Secondly, if the sensor is placed in a pool of developer machines, does it have to have the whole development environment loaded up, for example, and occasionally do compiles? "Doing anything different" seems to require close emulation of whatever is go…
- What is alerted on (or "attack") is configurable and can range from code being executed (which is the true positive alert) to connecting to ports(which has more noise) - It needs to look like the machine an attacker will be after when he's looking around on the network and that's much simpler then a whole loaded up environment. - Yes, the decoys look like an integral part of the network - It could be within every s…
Let's say that an attacking organization fully installs your sensor in their own lab. What is to prevent them from engineering an approach to fully defeat the sensor itself?

One final question. Let's say that an attacking organization fully installs your sensor in their own lab. What is to prevent them from engineering an approach to fully defeat the sensor itself?
On another note I agree that they will try and we will be constantly remembering that fact :)
