It'd be awesome to hear from someone with product experience.
My experience of DPI is limited to Tenix diodes (which are white-list based, and are more focused around stripping malicious code by converting known objects to another format, eg .jpg to .png and back, or Word to PDF and back), or McAfee's Secure Web (used to be Web Washer), which does URL filtering, SSL scanning, etc. Also white list based.
- colanderman 15y agoThe DPI in the product I work on is blacklist- and standards-based. i.e. it involves actually parsing most common formats, making sure that they are valid documents with no out-of-bounds values that could cause e.g. buffer overflows, and blacklisting known attacks. FWIW our product can do this very quickly (we sell a 1U which can inspect 8 Gb/s).
