The messages
are fully encrypted

At Esysco, we help you to protect your most vital communication channel design and implementation of centralised, easy to use and policy-based e-mail encryption solutions.

Centralised E-mail Encryption

E-mail is one of the world‘s most important communication tools. Messages sent and received from unsecured networks can pose a serious security threat. By encrypting your electronic communication easily and in a highly automated way, you can mitigate these risks and achieve regulatory compliance.

Centralised E-mail Encryption

Lack of encrypted communication leads to loss of valuable and confidential information which results in loss of credibility that might be devastating for your business.
Additionally, the situation can both weaken your organization’s position on the market and reveal valuable information.

Encrypted exchange of personal data and files with your customers and business partners in compliance with GDPR minimises the risk of an incident during data processing, as encrypted contents are unreadable for third parties.

End-to-end Encryption

End-to-end encryption protects electronic messages during the complete transmission between people, applications or devices. The messages are fully encrypted all the way from the sender’s client to the recipient’s inbox. Not only are the messages protected during transmission but also while they are being stored.

In a corporate environment, however, standard end-to-end encryption is difficult to achieve. Every user needs to possess a certificate of the designated recipient. The management of these certificates eventually becomes overwhelming.

Certificates cannot be centrally validated and encryption cannot be applied in a standardised homogeneous manner. This means that security processes are outsourced to individual employees instead of being managed centrally.

End-to-end Encryption

E-mails cannot be checked for viruses or spam and filters cannot be applied. Finally, because all e-mails are encrypted even when they are stored, the organisation may not be able to access any e-mails once the employee has left the organization.

The best solution to encrypt e-mails in a corporate environment is to install a secure e-mail gateway, which encrypts the e-mail exchange between the organization and external entities.

The secure e-mail gateway decrypts incoming e-mails and encrypts outgoing ones.

S/MIME, PKI & OTP

Nowadays, to avoid security gaps, organisations need to take a more strategic approach . Ideally, their focus should be on data and ensuring its security throughout the whole e-mail lifecycle, while using a single encryption technology that works across all devices and use cases.

The secure server-based system handles the complete e-mail traffic according to policies for users centrally and transparently. Compliance conformity and high user acceptance without the need for client-side software make the use of e-mail encryption gateways efficient and scalable.

For communication partners without a PKI, alternative secure delivery methods in which a two factor OTP replaces the private key are in place.

The security of password-based encryption is equal to PKI based encryption and represents a widely accepted and proven method of secure ad hoc encryption when certificates are not available.

All password-protected delivery methods are easy to use and ensure a seamless two-way communication by offering the possibility to send an encrypted response directly.
