Is Email Really a Safe Way to Share Sensitive Information?
Email is so embedded in working life that few of us think twice before attaching a document and pressing send. Contracts, financial information, customer records and confidential business documents are exchanged this way every day.
Email is now over 45 years old and was primarily designed for text communication, not for securely transporting sensitive data.
While organisations have invested heavily in email security, there is a difference between protecting an inbox and controlling what happens to confidential information once it has been sent. This is where secure email needs to form part of the wider data protection conversation.
One wrong recipient is all it takes
Some of the biggest risks are also the simplest.
Typing the wrong name into an address field or accidentally selecting “reply all” can expose confidential information instantly. Once a traditional email and its attachment have reached the wrong inbox, retrieving them can be extremely difficult.
Forwarding creates another problem. A document may originally be sent to an authorised recipient, but what prevents that person from forwarding it elsewhere?
Organisations should consider whether their secure email approach gives them sufficient control over information after it has left the sender.
What happens if an account is compromised?
Cyber criminals regularly target email accounts because of the amount of valuable information they contain. If an attacker gains access to an inbox, they may also gain access to years of attachments and conversations.
This means secure email cannot simply be about protecting a message while it travels between sender and recipient. Businesses need to think about the information itself and whether access can still be controlled after delivery.
Can a document be locked? Can access be removed? Can forwarding or downloading be restricted? Can the organisation see who has accessed the information?
These controls become particularly important when handling personal, financial or commercially sensitive data.
Do you know where your email data travels?
Another consideration can easily be overlooked: where information actually goes.
Cloud email services can involve data travelling through infrastructure located across different jurisdictions. For organisations with data residency or sovereignty requirements, understanding that journey matters.
A secure email strategy should therefore consider not only encryption but also where sensitive information is permitted to travel or be stored. Controls such as geofencing can provide greater oversight of data movement and help organisations keep information within approved locations.
Making secure data sharing easy
Security cannot come at the expense of usability. If sending information securely is complicated, employees will inevitably look for quicker alternatives.
The aim should be to make secure data sharing feel as straightforward as sending a normal email, while giving the organisation greater visibility and control behind the scenes.
Think before you attach
Email isn’t going anywhere, nor should it. The question is whether every piece of information belongs in a conventional email attachment.
Before sending sensitive data, organisations should consider who needs access, how long they need it, whether it can be forwarded and what happens if it reaches the wrong person. Secure email is ultimately about keeping control of sensitive information even after somebody presses send.
