Smoke Signals or Just Signal?

I’ll never forget the day I learned the hard way about the fragility of privacy. A close friend sent me a message—nothing scandalous, just personal. A few days later, I discovered that someone else had read it. Not because they were nosy, but because the platform we used didn’t protect our conversation. It was a wake-up call. In that moment, I realized how vulnerable our digital lives can be. And it wasn’t just about that one message—it was about every conversation, every shared thought, every private moment that could be exposed.

That’s when I started to take encrypted communication seriously. And today, I want to share why it should matter to you, too.

What Is Encrypted Communication?

Imagine sending a letter in a locked box. Only the person with the key can open it and read what’s inside. Encryption works the same way—it scrambles your messages so that only the intended recipient can make sense of them. Even if someone intercepts the message, all they see is gibberish.

Encryption isn’t new. It’s been used for centuries to protect secrets, from wartime communications to diplomatic cables. The Ceasar Cipher earns its namesake due to use in ancient Roman times. But in the digital age, more advanced algorithms have become a tool for everyone. Apps like Signal and WhatsApp have made it as easy as sending a text. You don’t need to be a tech wizard to use it—just download the app, and you’re good to go.

The State of Our Digital Privacy

Despite the availability of these tools, many of us still rely on unencrypted methods like regular SMS or email. It’s like leaving your front door wide open while you sleep. You might think, “I’m not doing anything wrong, so why should I care?” But privacy isn’t about hiding wrongdoing—it’s about controlling who has access to your personal life.

Consider this: in 2013, Edward Snowden revealed that the NSA was collecting data on millions of Americans’ phone calls and internet communications. Even if you’re not a target, your data could be swept up in such dragnets. And it’s not just governments—hackers, cybercriminals, and even nosy corporations (looking at you Google and Meta) are constantly looking for ways to access your information.

The risks are real. Data breaches happen daily, exposing everything from passwords to private conversations. Without encryption, your messages are like postcards—anyone who handles them can read what’s written.

Why Encryption Is Your Best Defense

Encrypted communication is one of the few tools that gives you back control. It ensures that only you and the person you’re talking to can read your messages. Even the service provider can’t access them, thanks to something called end-to-end encryption. This means your conversations stay private, no matter who tries to pry.

Here’s the thing: encryption isn’t just for activists or whistleblowers. It’s for anyone who values their privacy. Whether you’re discussing personal matters, sharing financial details, or just chatting with friends, encryption protects your right to keep those conversations to yourself.

And don’t worry—using encryption doesn’t make you look suspicious. It’s like locking your door at night. You’re not hiding anything; you’re just being smart.

How to Protect Yourself: Simple Steps for Everyone

Ready to take control of your digital privacy? Here are a few easy recommendations:

• Use encrypted messaging apps:

  • Signal and WhatsApp are great options. Signal is open-source and run by a nonprofit, making it a top choice for privacy enthusiasts. WhatsApp also offers end-to-end encryption, though some may prefer Signal for its stronger privacy stance.

• Enable end-to-end encryption on any platform that supports it:

  • This ensures that only you and the recipient can read the messages.

• Avoid sharing sensitive information over unencrypted channels:

  • Like SMS or regular email.

  • If you need to send secure emails, consider services like ProtonMail or Tutanota, which offer built-in encryption.

• Keep your apps updated. 

  • Regular updates ensure you have the latest security features and patches.

For those who want to go a step further:

• Use a VPN in conjunction with encrypted messaging for added security, especially on public Wi-Fi.

• Explore PGP (Pretty Good Privacy) for encrypting emails manually, though it’s a bit more technical.

The Bigger Picture

Privacy isn’t just about hiding—it’s about autonomy. In a world where our attention is constantly monetized and our data is harvested; encryption is a way to reclaim control. It’s about deciding who gets to know what about you, and when.

Think about it: every time you send an unencrypted message, you’re giving away a piece of your privacy. But with encryption, you’re drawing a line in the sand. You’re saying, “This is mine, and I choose who sees it.”

It’s a small act, but it’s powerful. And in a digital landscape where our personal information is increasingly vulnerable, that power matters.

Is Encryption Too Complicated?

Some people worry that encryption is too technical or that it might make them stand out. But the truth is, it’s never been easier to use. Apps like Signal work just like any other messaging app—you don’t need to understand the cryptography behind it to benefit from it.

And as for standing out? In a world where privacy is under siege, using encryption is a sign of awareness, not suspicion. It’s like wearing a seatbelt—you’re just being cautious.

A Final Thought: Your Digital Life Deserves Protection

Our digital habits shape our lives in ways we don’t always see. Every message, every email, every shared photo is a part of your personal story. Encryption ensures that story stays yours to tell.

If you’re looking to take your privacy and security to the next level—whether for yourself or your organization—consider consulting with experts who specialize in protecting digital communications. At Marathon Security Consulting, we help individuals and businesses safeguard their data and maintain their privacy in an increasingly connected world.

But for now, start small. Download an encrypted messaging app. Lock down your conversations. Reclaim your privacy.

Stay safe out there.
