No, unfortunately not. If the target phone is a compatible Blackberry device then you’re out of luck. Its not only Guardian that cannot capture WhatsApp on a Blackberry…there is NO product on the market that can. This is due to limitations imposed by the manufacturer and finding a workaround is not possible at this stage as the Blackberry operating system is proprietary and therefore very little data (particularly the API data that would be required) is publicly available. There are solutions available to monitor the WhatsApp conversations separately, but they require the WhatsApp account to be set up (one time only) on either an Android phone or on the PC version of WhatsApp. Contact our Dave Wilson (dave [at] guardian [dot] software) for more information.
