THE LATEST THOUGHTS FROM THE FOUNDER
A running column from Frank Saulsbery. Not a sales pitch, just the way he’d explain it if you pulled up a stool next to him. Meet Frank →
A SNEAK PEEK…
“If the information could cause a problem if it ended up in the wrong hands, it should be encrypted.”
“Isn’t email already secure? Why would I need to encrypt something in Outlook?”
That question usually comes up right after someone is about to send something a little more sensitive than usual. Maybe it is a spreadsheet with employee payroll information, a client’s bank details, or even just a message that feels a little too private to be floating around.
And I get the hesitation, email feels routine. You send dozens a day, probably without thinking twice, it’s easy to assume it’s already protected well enough.
Most email systems, including Microsoft and Gmail, do protect messages while they are moving across the internet. That part is helpful, but that’s only part of the story. Once the message arrives and is stored in an inbox, it may still be sitting there in a readable format unless you take an extra step.
A simple way to think about it is this. Sending a regular email is a bit like sending a postcard. It gets where it needs to go, but anyone along the way or with access afterward could potentially read it. That’s where encryption comes in. When you encrypt an email, you are essentially locking the contents so only the intended person can open and read it. Instead of normal text, the message becomes scrambled, and only the right recipient can turn it back into something readable.
In Outlook, this is not complicated. When you’re writing an email, there is an Encrypt option, usually under the Options tab with a little lock icon. You click that, choose your level of protection, and send it like you normally would. There are even options that let you go a step further. You can prevent someone from forwarding the message or copying the content. That can be useful when you’re sharing something you really want to stay contained.
Now, the next practical question is when should you actually use it? A good rule of thumb is simple. If the information could cause a problem if it ended up in the wrong hands, it should be encrypted. That includes things like Social Security numbers, driver’s license details, home addresses, financial account information, or even health related data. These are all examples of personal or sensitive data that can be misused if exposed.
It also applies to your business. Internal financials, contracts, client data, or even conversations around legal matters can create real issues if they are forwarded or accessed by the wrong person.
That said, not every email needs to be locked down. If you are sending a meeting invite, a quick question, or general updates, encryption is probably overkill. Like most things in business, this comes down to judgment, not a strict rule.
Where I tend to see business owners run into trouble is not that they never encrypt, but that they don’t think about it until after something has already been sent. And at that point, there’s not much you can do.
So the goal here is not to make email complicated. It is simply to raise awareness so you can pause for a second when something important is about to go out the door. If you think about your own business for a moment, how often are you or your team sending information that would be uncomfortable if it was accidentally shared or exposed?
That question alone can help you decide whether email encryption should become a regular habit. If you are using Outlook, take a few minutes to find that encrypt button and understand your options. You do not need to use it every time, but it is a great tool to have ready when the situation calls for it.
That’s how I see it, anyway, and I’d enjoy hearing how you see it. None of this is a sales pitch. It’s just the kind of thing I’d talk through with you if we were sitting across the table. If it raised a question, or you think I have it wrong, I want to hear about it.
My door is always open. Whether you want to talk this through or just say hello, you can reach me anytime.
