A client of ours got hit with a $160,000 wire fraud. The attacker didn’t use some sophisticated zero-day exploit. They didn’t hack through a firewall or deploy custom malware.
They logged in with a stolen password.
That’s it. A compromised credential, no multi-factor authentication, and $160,000 gone before anyone noticed. The whole thing took less than 20 minutes.
I’m not telling you a story from a report or a case study from some other country. This happened to a business right here in our client base. A real company, real people, real money.
And the worst part? It was completely preventable. Microsoft reports that MFA blocks over 99.2% of account compromise attacks.
Multi-factor authentication (MFA) would have stopped that attack cold. Even with the stolen password, the attacker would have needed a second verification: a code from a phone, a biometric scan, a hardware key. Without it, the password is useless.
MFA is the single cheapest, most effective security measure any business can implement today. And somehow, a shocking number of companies still haven’t turned it on.
MFA requires two or more forms of verification before granting access to an account. Usually, that’s something you know (your password) plus something you have (your phone) or something you are (your fingerprint).
That’s the whole concept. It’s not complicated.
The reason it works so well is that passwords alone are fundamentally broken. People reuse them across personal and work accounts. They pick weak ones that can be cracked in minutes. They get phished by emails that look legitimate. They show up in data breaches that happened three years ago, and nobody ever changed them.
MFA makes all of those problems manageable. Even if your password is compromised, the attacker still can’t get in without that second factor.
Microsoft’s own data shows that MFA blocks 99.9% of automated account compromise attacks. Not 80%. Not 90%. Over 99%.
Let that sink in.
For something that costs nothing to enable on most platforms (Microsoft 365, Google Workspace, banking portals, VPNs), there is no excuse for not having it turned on. The ROI isn’t just good. It’s almost infinite.
And yet, we still onboard new clients every month who don’t have MFA enabled on their email. These are smart business owners. They just didn’t know what they didn’t know. That’s the gap that costs companies thousands.
I hear the objections all the time:
“It’s annoying.” Yes, it adds a few seconds to your login. You know what’s more annoying? Explaining to your clients that their data was stolen because you didn’t want to tap a button on your phone.
“My team will push back.” They will, for about a week. Then it becomes habit. We’ve rolled out MFA for hundreds of businesses and the complaints disappear within days. Every single time.
“We’re too small to be a target.” This is the most dangerous myth in cybersecurity. Small and mid-sized businesses are the primary target now because attackers know you have fewer defenses. You’re not too small to be a target. You’re the perfect target.
“Our IT guy said we don’t need it.” If your IT person is telling you MFA isn’t necessary in 2026, you need a new IT person.
Let me be clear: MFA alone is not a complete cybersecurity strategy. It’s the foundation. The floor, not the ceiling.
Once MFA is in place, you should be looking at Conditional Access policies that control where and how people can log in. You need prevention measures that go beyond just authentication. You need endpoint protection, email security, and employee training.
But none of that matters if someone can log into your email with just a password. MFA is step one. Everything else builds on top of it.
Here’s what we do at Keeran Networks when we implement MFA for a client:
Start with the critical accounts. Email, financial systems, VPN access, admin accounts. These get MFA first, no exceptions.
Use authenticator apps, not SMS. Text message codes are better than nothing, but they can be intercepted through SIM swapping. An authenticator app (Microsoft Authenticator, for example) is significantly more secure and just as easy to use.
Communicate before you enforce. Don’t just flip the switch on a Monday morning. Give your team a heads-up, walk them through the setup, and have your IT support ready for questions on day one. A little planning goes a long way toward adoption.
Enforce it across the board. No exceptions for the CEO. No exceptions for the person who’s “not technical.” Everyone. Every account. Every time. The moment you make an exception, you’ve created a vulnerability.
Monitor and review. Cybersecurity isn’t set-it-and-forget-it. Review your MFA policies, check for users who haven’t enrolled, and stay on top of new authentication methods as they become available.
Remember that $160,000? That’s one incident. One compromised account. One missing security control.
Now multiply that by the potential for ransomware, data exfiltration, business email compromise, and regulatory fines. The average cost of a data breach for a small business in Canada is climbing every year. Many businesses don’t recover. They close within 18 months of a major incident.
Your networks and systems are only as secure as the weakest login credential in your organization. MFA eliminates that weakness overnight.
MFA is free to enable on most platforms. It takes less than a day to roll out. It blocks virtually all credential-based attacks.
If you’re running a business without MFA in 2026, you’re gambling with your company’s future over a minor inconvenience. That’s not a trade-off. That’s a mistake.
We help businesses implement MFA properly, as part of a comprehensive security posture that includes multi-device management and incident response planning. If you’re not sure where you stand, let’s talk.

What is MFA and how does it work?
Multi-factor authentication requires two or more forms of verification to log in: something you know (password), something you have (phone or security key), or something you are (fingerprint). Even if an attacker steals your password, they can’t log in without the second factor.
Does MFA really prevent data breaches?
MFA blocks over 99% of automated account compromise attacks. It’s the single most effective security control any business can implement. Most breaches that involve stolen credentials succeed specifically because MFA was not enabled.
What is the best type of MFA for business?
Authenticator apps (Microsoft Authenticator, Google Authenticator) and hardware security keys (YubiKey) are the most secure. SMS-based MFA is better than nothing but vulnerable to SIM-swapping attacks. For most businesses, authenticator apps offer the best balance of security and convenience.
How long does it take to roll out MFA across a company?
For a business with 20–50 employees, a full MFA rollout typically takes 1–2 weeks including communication, training, and enrollment. The technical setup is fast — the time investment is mostly in helping employees through the change.
