Encryption still Works
The reason is simple: it’s built on math that a bigger computer can’t brute-force away.
Most people picture hackers cracking encryption like a safe. In practice, they usually skip the safe and go after the key, the password, or the person holding them. Stolen passwords, reused logins, and a convincing phishing email do more damage than any math problem.
The math itself is hard to beat. AES-256 is a widely used standard, and its keys come from a space of 2^256 possibilities. 2^256 is a 78-digit number (115792089237316195423570985008687907853269984665640564039457584007913129639936*). Writing it out as zeros would take a line about 10^47 times the width of the observable universe, if each zero were one millimeter wide.
Quantum computers are a real long-term concern. They could weaken some public-key methods that protect website connections and signatures, and that’s why NIST finalized the first post-quantum standards in 2024. For symmetric encryption like AES-256, the quantum speedup only roughly halves the effective key strength, leaving it about 128 bits of protection, which is still far beyond practical reach.
So the realistic risk for most small businesses isn’t a quantum computer cracking their files tomorrow. It’s a weak password, a shared login, or an account nobody turned on two-factor authentication for. Strong encryption is necessary, but it’s only as good as the keys, passwords, and habits around it.
*The number written out in words just for fun:
One hundred fifteen quattuorvigintillion, seven hundred ninety-two tresvigintillion, eighty-nine duovigintillion, two hundred thirty-seven unvigintillion, three hundred sixteen vigintillion, one hundred ninety-five novemdecillion, four hundred twenty-three octodecillion, five hundred seventy septendecillion, nine hundred eighty-five sexdecillion, eight quindecillion, six hundred eighty-seven quattuordecillion, nine hundred seven tredecillion, eight hundred fifty-three duodecillion, two hundred sixty-nine undecillion, nine hundred eighty-four decillion, six hundred sixty-five nonillion, six hundred forty octillion, five hundred sixty-four septillion, thirty-nine sextillion, four hundred fifty-seven quintillion, five hundred eighty-four quadrillion, seven trillion, nine hundred thirteen billion, one hundred twenty-nine million, six hundred thirty-nine thousand, nine hundred thirty-six.
1 quadrillion = Every dollar in human history, roughly.
Most small business owners we talk to can’t answer one simple question:
When did you last back up your main business computer, and can you restore it if it died today?
Many don’t know whether their backups are encrypted, where they’re stored, or if they’ve ever been tested.
So here’s a question: how often are you backing up your critical systems?
Not “we have cloud storage,” but a copy you can physically reach if the cloud account gets locked, deleted, or ransomed.
If you don’t know the answer, that’s a good reason to talk.
