Alternative to totemomail and Sophos UTM: Seamless migration to Z1 SecureMail Gateway

Z1 SecureMail Gateway as alternative to Sophos UTM & totemomail

Sophos UTM discontinuation & alternative solution for totemomail

The market for email encryption solutions is dynamic. Thus, product discontinuations and company acquisitions occur from time to time. Two recent examples are the companies Sophos and totemo.

Recently, Sophos announced the end-of-life for Sophos UTM, suggesting that their customers transition to a cloud-based SaaS solution. However, storing keys with providers can present compliance challenges for EU companies when the provider is located in the US.

After the acquisition of the Swiss company totemo, customers using their product totemomail are now being encouraged to switch to the US-based buyer Kiteworks. This has left those customers preferring a European provider with German support in search of alternatives.

Efficient email encryption for totemo and Sophos customers

If you’ve been with totemo (now Kiteworks) or Sophos and are currently seeking an alternative solution that offers the familiar security and ensures a smooth transition, you’re in the right place. Our proven email encryption solution Z1 SecureMail Gateway guarantees a high level of security and convinces with efficiency, which clearly stands out from your usual solutions. This is primarily achieved through highly automated certificate management and adjustable Z1 Policies that serve as central security guidelines.

What sets Z1 SecureMail Gateway apart from other email encryption gateways? In addition to managing your own email certificates, the gateway also ensures that certificates from your communication partners are available. As a reseller of various trust centers, Zertificon provides not just a technical interface but also facilitates a seamless procurement process for email certificates.

Employees usually don’t need to initiate a manual key exchange via signed email when using the S/MIME standard. The key exchange process happens automatically in the background powered by Zertificon’s own certificate portal, Z1 Global TrustPoint. The unlimited, easily configurable Z1 Policies enhance both efficiency and security. The central configuration of these security policies reduces the workload of employees. Encryption cannot be forgotten but happens automatically behind the scenes.

Keys and certificates management: A critical factor during migration

Switching to a new email encryption provider can often bring about uncertainty. Particularly, managing keys and certificates can be a challenging task. Customers want to ensure their sensitive information remains in the best hands. Additionally, it’s important that the migration process is as effortless as possible. Fortunately, migrating to Z1 SecureMail Gateway is a seamless process.
