If you’re familiar with the web service IFTTT, you’ll feel right at home with the concept of Digital Sentry.
Digital Sentry monitors your system for specific events, and then can perform a vast array of unique actions in response. Use it to automatically cleanse internet history when closing a browser, automate redundant computer tasks, perform covert surveillance, or even protect your sensitive data during unauthorized access or theft!
For example, you could set Digital Sentry to monitor your Mac and inform you via email and/or text message when a specific application is launched. Or you could set it to take a screenshot and email it to yourself when someone tries to break in to your Mac.
I spent a good hour running through Digital Sentry, setting up and testing all sorts of combinations of actions. The possibilities are too numerous to go through here, but I assure you that everything I tried worked perfectly.
Digital Sentry is available for $19.95, runs on Mac OS X 10.6 or later, and a 15-day downloadable demo is available.
