> Impressive! What do you think it is that you do that allows you to compete with VirusTotal, and even free tools like Jotti?

Thanks and good question. We don't really compete with virus total since it's more of a research tool and, for a while, their terms explicitly prohibited commercial use (but I think that has changed). Jotti is a similar thing, more of a research tool than a high performance API you can use to build commercial products on.

> Presumably you're now using commercial AV tools, rather than Clam? Did you have to get some kind of special license from them to use it like this?

Yeah the product has expended a bunch over the years and we use multiple detection engines [2] to catch all kinds of unsafe content. But you are right, we do license a commercial AV engine to act as a backup to our own to ensure best possible detection rates. The licensing process warrants a blog post of its own since it's not what I would call easy.
