The basics How it works

Most secure informationsharing tools forget one vital thing – the human factor. No matter how secure your system, if employees and clients avoid using it because it’s slow or complex, it won’t protect you from risk. Secure Messaging is the easiest way to encrypt and send confidential or sensitive data. You can send information protected with military-grade AES-256 encryption from within your standard Microsoft Outlook window. What’s more, when your clients reply, their messages and attachments will be protected to the same level, free of charge to them. We’ve stripped out the time-consuming steps which cause frustration in traditional secure email, portal, or mobile app messaging. Not only that – we’ve added in extra protections. Our emails are encrypted both in transit and at rest. You can even send messages securely to a shared inbox, by including a question or SMS code known only to the intended recipient. And by switching from registered post to a secure digital system, you’ll save on costs and carbon emissions.

The OASIS difference Why choose Secure Messaging from OASIS?

Secure – in transit and at rest

Other ‘secure’ email services only protect information in transit – Secure Messaging protects it at rest too, in line with Information Commissioner’s Office (ICO) guidelines. 

Manual or automated encryption

Rules can also be configured within your mail server to automatically encrypt sensitive messages or prompt the sender to encrypt manually before sending. 

Happier team, happier clients

It’s quick and simple for employees to send information securely, directly from their Outlook window. And all recipients get a free account to reply with the same level of protection.
