"I am a security architect, offsec practitioner, and have been in the security game for over two and half decades -- some salt acquired. Our company, Semper Victus, operates as a high-end consultancy solving problems and building things often in the far reaches of "greenfield" for enterprise clients and world-class universities. We focus on healthcare and financial services in our commercial efforts, with non-commercial work supporting academia, non-profits, and USG efforts. Everywhere we go, regulatory compliance and operational security are prevalent, and the criteria for compliance are getting stricter (thankfully) by the day.
We've been a MailRoute customer for years, and recommending it for adoption by clients all the way through. What started as a pure technical proficiency play (I've been lucky enough to converse with MailRoute's founder on a number of occasions to get a peek under the hood) grew into a happy business relationship wherein MailRoute is constantly expanding the back-end functionality and front-end access to it, driven by customer demand, and keeping true to their philosophy of simplicity.
Customers don't need a consultant priced like a good lawyer to manage their filters and policies, deal with turnover, and access their quarantine even in complex industries such as healthcare marketing.
On the rare occasion when we need to interact with support, responses are rapid, effective, and honest. MailRoute services are priced so as not to break the piggy bank of your kids' lemonade stand, and scale up to enterprise flow and filter requirements as the business grows up. Definitely worth a look if you're responsible for the commsec of your organization and don't want to go down every time some public cloud upchucks its message queues."
