Thomas- Having a sandbox that could test/scan and auto release the myriad of PDF's with javascript in them would be a big boost to our tiny charity. No more staff requests to let a PDF through!! Can you provide some more information on what opensource packages you've selected to piece together? The integration into ASSP sounds fantastic! I think your cloud offering would get some real traction with those who can afford it and have policies that allow external scanning of emails.
Bob- I do nightly block reporting reviews and also get requests from users throughout the day (10x a day or more sometimes). It's a pain, but I've found it necessary to keep ASSP healthy given the variety and sometimes not of our messages. Releasing is easy through the ASSP GUI: open the mail from the log or the block report, select Resend and Force Attachments. You used to have to hand edit the header, but Thomas was gracious enough to entertain my suggestion of having a drop down to do it. That alone saved me a good amount of brain power :) On Wed, Mar 11, 2020 at 6:58 AM Thomas Eckardt <thomas.ecka...@thockar.com> wrote: > You can buy such sandbox systems from different vendors (eg. checkpoint, > cisco .. and some more - prices from 30.000 EUR to 500.000 EUR).
