The best thing about Clearswift is that it is easy to use and it is always up to date with all the latest security patches and updates. It is secure and has a good customer service team. It is also very easy to configure. The only thing that I dislike is that it can be quite expensive for small companies. I would recommend Clearswift Secure Email Gateway to anyone who needs a secure email gateway. We are managing the emails for a small business and it is easy to use and it is always up to date with all the latest security patches and updates.
