How do the different detection engines work?

Scanii is a content detection service capable of detecting a variety of content depending on the detection engine enabled. Content detection engines can be enabled (and disabled) on a per API key basis giving you a large amount of configuration options.

Malware

Our malware detection engine is Scanii's original detection engine and has evolved considerably over the years. We believe that our detection rate is as good as our commercial competitors but our performance and ease-of-use is unmatched. We can confidently say that due to our redundant engines setup where we pair our own engine with a top-tier commercial engine fallback, if, for any reason, our engine fails to identify a specific class of malware, our commercial engine will. Today we OEM Sophos for that fallback engine.

With that said, we encourage all of our customers to not take our word for it but, instead, to create a free scanii account and try it for themselves.

If the file you send us for processing is an archive (Zip, Gzip, RAR, etc) we will expand/decompress and analyze the contents individually as long as the archive is not password protected
Our malware engine is a meta engine that utilizes multiple distinct malware detection engines/products in order to increase overall accuracy. Today we pair our own engine with a top-tier commercial engine as a
Like all other malware engines, our engine properly identifies the EICAR test file.
