The #1 Cybersecurity Mistakes Most Small Businesses Make - And How it Could Cost Them Millions

🌟 Editor's Note

Welcome to the first issue of our cybersecurity newsletter for small firms - where you can learn how to improve the technical aspects of your organization in a non-technical way. Each week, we’ll share practical insights to help you reduce risk, stay compliant, and protect your reputation. The goal of this newsletter is to help you stay informed of the changing landscape that is cybersecurity.

🧭 Industry Context & Risk Landscape

Why Does This Matter

You might be opening this cybersecurity newsletter thinking, “Oh. This topic again…” I get it. Cybersecurity often feels like a dark, intimidating void full of problems, something comparable to going to the dentist. Nobody likes doing it. We all say we should, but it’s like pulling teeth just to schedule the appointment. And just like skipping regular dental checkups can lead to painful, and expensive, issues down the line, putting off cybersecurity for your organization can create major, costly problems.

You might also be thinking, “I run a small firm. Hackers aren’t after me.” But let me ask you this: if I were a bank robber choosing between two targets, one being a massive institution with cutting-edge security and armed guards, and the other a small, neglected bank with outdated systems and a decent payout, which one do you think I’d go after?

Exactly. I’d go for the biggest bang for my buck.

That’s how cybercriminals think. They go after the easy wins. If they can't breach the hardened systems and MFA protections of a Fortune 500 company, they’ll simply move on to the small boutique firm that hasn’t implemented multi-factor authentication or a password policy. The idea that cybercriminals only target large organizations? It’s a myth. In reality, small firms are often the primary target, not necessarily for money, but for something even more valuable: information.

The Value of YOUR Clients’ Data on the Black Market

As mentioned, cybercriminals aren’t always chasing money directly. In fact, data is often more valuable than cash. Here’s how it typically plays out: a cyber gang breaches a firm and collects as much sensitive data as possible, including Personally Identifiable Information (PII), like names, addresses, and Social Security numbers; financial details such as bank account and routing numbers; legal documents; and even internal company secrets.

Once gathered, this data is packaged into files, uploaded to black market forums on the dark web, and auctioned off to the highest bidder, paid in cryptocurrency. At that point, the breach doesn’t end. That data is usually purchased by more sophisticated cybercriminals who then weaponize it, using it to commit fraud, blackmail, or further intrusions that can cripple the original organization. Many of these attacks lead to firms being shut down or bankrupted.

As the saying goes: “He who controls the information controls the money.” In cybersecurity, this couldn’t be more true.

🚨 Evolving Cyber Threat Vectors Facing Professional Firms

Phishing

Phishing is by far the largest attack vector used by cybercriminals and will continue to be for the foreseeable future. Again, think about “bang for buck,” what’s easier to trick, a human or a machine? In Verizon’s 2025 DBIR Report, 60% of all breaches involved human interaction, whether that was through error, manipulation, or misuse. Seventeen percent of all breaches start with phishing. Phishing is the largest threat, and that’s why it is absolutely critical that one of the first security measures you take to lock down your environment is training your staff.

Ransomware

If you are unfamiliar, ransomware is a type of malicious software that can be installed on your machine either through an email attachment or by visiting a malicious site. Once installed, the program will either lock your machine and prevent access, encrypt all of your files and hold the decryption key for ransom, or threaten to release your files on the black market. Nothing will be done until a payment is made. Ransomware is detrimental to organizations because it almost always results in a lose-lose situation. If you refuse to pay, you lose access to your documents and corporate information. If you make the payment, you lose money, and you also risk the fact that you are dealing with criminals who may take your money and disappear. It is essential to ensure anti-malware is installed on all machines throughout your environment and that staff are properly trained not to install suspicious files or click on unknown links from the internet.

Business Email Compromise (BEC)

BEC is one of the most financially devastating cyberattacks today, and the worst part is that it usually doesn’t involve any malware at all. In a BEC attack, a cybercriminal gains access to, or spoofs, a legitimate business email account, often that of a partner, vendor, or executive, and then uses it to manipulate someone into sending money, wiring funds, or sharing sensitive information. These attacks are so successful because they look like normal business communication, and by the time anyone realizes it’s a scam, the money is gone. What makes BEC especially dangerous is that it preys on trust and routine. You’re not questioning an urgent request from your CFO or managing partner, but maybe you should be. The best defense against BEC is layered: enable multi-factor authentication (MFA) on all email accounts, flag external senders, and most importantly, train staff to always verify unusual requests, especially those involving money or sensitive data.

🛡️ Recommended Risk Mitigation Strategies

Mistakes Small Firms Make

One of the biggest mistakes small firms make is assuming they’re “too small to be targeted.” That mindset is exactly what attackers look for. In reality, small and mid-sized law and accounting firms are attractive targets because they often lack dedicated cybersecurity resources. Another common pitfall? Relying solely on your outsourced IT provider to handle everything related to security. IT and security are not the same. Just because your systems are running doesn’t mean they’re secure. Many firms also skip basic security controls like MFA, don’t enforce password policies, and never test their staff with simulated phishing emails. These oversights may seem minor, until they cost you access to your data or expose client information.

Actions To Take Today!

You don’t need a massive budget to start improving your cybersecurity posture, just a plan and some consistency. Start by enabling multi-factor authentication (MFA) across email, cloud storage, and any remote access tools. Next, schedule a short training session with your team focused on how to spot phishing emails, social engineering tactics, and safe file practices. Make sure your antivirus is up to date across all endpoints, and ensure regular backups are happening and stored securely. Finally, review who has access to what, staff should only have the permissions they need to do their job. These are basic steps, but when combined, they go a long way in reducing your firm’s attack surface.

How a Trusted Security Advisor Can Assist

Navigating cybersecurity isn’t just about technology, it’s about knowing what matters most to your specific environment and industry. A trusted advisor helps cut through the noise and prioritize the things that will actually reduce risk. That might mean helping your firm understand insurance requirements, mapping out compliance gaps, or running a mock phishing campaign to test your team. It’s not about selling software, it’s about having someone who understands both the threats and the business context, and who can guide your firm toward practical, sustainable security practices without disrupting operations. Sometimes, having the right person in your corner makes all the difference between being reactive and being prepared.
