Actamo is easy to use, has excellent customer support with real people (not an AI) who care about their solution. They are actively improving upon it by adding new features all of time without sacrificing performance or reliability. I have no complaints at this point in our relationship. We've been using actamo as part of a small company's anti-spyware solution since 2014. It was one of the only ones out there doing what we needed (full disk encryption). The price was good too! I haven't seen any updates that weren't improvements over previous versions. Our users love not having spyware pop up ads when they open mail from us! We use Actamos to protect our organization from phishing and malware attacks, it's very easy to set up and manage, the integration with other services is great, there are no downsides at this time. I would like that they offer more features for advanced users, such as blocking spam in transit and being able to configure filters/rules. We have an office where many employees work remotely, we're trying to keep the phishing and malware attacks away from them.
