The BEST protection against ransomware

What would you do if you went to work tomorrow and discovered all your files were missing?
Not just missing, but locked, encrypted, and held for ransom by criminals demanding a large sum to release them.
Perhaps.
That's the reality of ransomware. And it's becoming more prevalent.
In the first quarter of 2025, ransomware attacks reached a record high, increasing by 84% compared to the same period last year.
It's no longer a question of "if" your business might be targeted, but "when".
In fact, two-thirds of businesses have experienced ransomware attacks in the past two years. It's a statistic that makes you pause and consider: Is your business prepared?
Now, the good news (yes, there is some) is that there is an effective way to protect your business: Immutable backup storage.
I'll explain what that means in a moment.
First, a brief overview of ransomware. It's a type of cyber attack where criminals infiltrate your systems, encrypt your files, and demand a ransom to unlock them.
It's a serious threat.
And these attacks don't just target your everyday files anymore. Recent research shows that 96% of businesses hit by ransomware in the last two years also had their backups targeted.
That's right. The attackers are aware of that safety net you thought would protect you, and they're targeting it.
This is where immutable backup storage comes into play.
"Immutable" means unchangeable. With immutable storage, once your backup data is written, it cannot be altered, deleted, or overwritten, even by someone with administrative access.
This means that if a ransomware attacker manages to access your system, they still can't tamper with these backups. It's like placing your most critical information in a vault, locking it up, and discarding the key... except you still have a secure way to access it when necessary.
Traditionally, businesses achieved this by storing backups on devices physically disconnected from the network, known as "air-gapped" storage.
But today, we have smarter, cloud-based solutions that offer the same level of protection without requiring bulky hardware or complex routines.
So, why isn't every business using immutable backups?
That's a great question. Despite 81% of IT professionals acknowledging it as the best way to guard against ransomware, only 59% of businesses are utilizing it. And that's concerning.
Today, simply hardening security isn't enough. Firewalls, security software, and careful user permissions are all part of the defense. But if ransomware breaches these defenses (as it often does), your last line of defense is your backups.
They must be untouchable.
I call it having a "breach mentality". Operating under the assumption that an attack will occur at some point. This means preparing for recovery, not just prevention.
Investing in immutable backup storage is one of the smartest moves you can make right now. When the worst happens, being able to restore your data swiftly and securely (without paying a ransom) can be the difference between a bad day and a business-ending catastrophe.
