We have been using altru for our email archiving solution since 2014 when we first implemented it as an in house product at my previous employer (the US Army). It's worked flawlessly ever sense then! The support team has always gone above & beyond to help us with any issues or questions related directly from their platform/solution - no matter how small they may seem like something minor compared other providers out there who are more "pushy" about getting you onboard right away without giving much thought into your needs / requirements etc... I've never had anything bad come up during this time period either so far!! They do offer free trials if needed but nothing wrong here really just be sure what exactly YOU need before going ahead wtih them because sometimes things can get complicated quickly once contracts start being signed between both parties.
