Cyberattacks are not only a problem for large corporations.
Growing businesses are attractive targets. They depend on cloud applications, email, online banking, remote access, and third-party providers, often with smaller security teams and budgets than the risk requires.
For companies with 20 to 200 employees, that is a tough spot: valuable data, dozens of cloud applications, hundreds of accounts and devices, and no dedicated security team monitoring all of it. Attackers understand this, and it is exactly what I see them exploit most often.
The good news: you do not need to defend against every attack equally. The better approach is understanding the threats most likely to affect you and focusing resources where they reduce the most risk. Here are the risks growing businesses should be watching right now.
- Unpatched Vulnerabilities
One of the biggest risks is also one of the most preventable: known vulnerabilities that never get fixed. They show up in operating systems, applications, VPNs, firewalls, network appliances, and cloud environments. Once a vulnerability becomes public, attackers actively search for organizations that have not patched it.
The challenge is scale: dozens of applications and network devices make it hard to know exactly which updates need immediate attention.
How to reduce the risk:
Maintain visibility into your devices and software, scan regularly, prioritize critical internet-facing systems, and establish a clear patching process. The goal is not a long vulnerability report. It is fixing what creates the greatest risk first. - Stolen Passwords and Account Takeovers
Attackers do not always need sophisticated malware. Sometimes they simply log in. Passwords get stolen through phishing, credential-stealing malware, past breaches, fake login pages, or reuse. Once an attacker has valid credentials, the activity can look like a legitimate employee signing in.
That makes identity security critical as businesses depend more on Microsoft 365, Google Workspace, CRM, and accounting platforms. One compromised account can expose sensitive information or open the door to additional systems.
How to reduce the risk:
Require MFA across critical systems, eliminate password reuse, protect privileged accounts, and monitor suspicious login activity. Administrative accounts deserve extra protection, because compromising one gives an attacker far greater reach. - Phishing and Social Engineering
Employees constantly receive emails, messages, calls, and login requests, and attackers use that environment to their advantage. Phishing may try to steal passwords, deliver malware, redirect payments, or convince someone to act on the attacker’s behalf.
Social engineering has also moved beyond email into text messages, phone calls, collaboration platforms, and increasingly convincing AI-generated communications. The attacks that work best usually just look like normal business activity.
How to reduce the risk:
Combine technical email protection with employee awareness. Employees should recognize unusual requests and have a simple way to report them, with particular attention on finance, HR, IT, and anyone who can move money or access sensitive information. - Business Email Compromise and Payment Fraud
One dangerous form of social engineering is Business Email Compromise, or BEC. An attacker impersonates an executive, supplier, customer, or employee to convince someone to transfer money or change payment details.
In more advanced cases, attackers compromise a real email account and quietly monitor conversations, waiting until a genuine invoice is in progress before inserting fraudulent banking instructions. That is what makes it convincing: the message shows up inside a legitimate conversation.
How to reduce the risk:
Create verification procedures for financial transactions. Changes to banking information, unusual payments, and large transfers should be independently verified through a trusted communication method. A phone call stops what expensive security technology often misses. - Ransomware
Ransomware remains one of the most disruptive threats businesses face. Modern incidents usually involve far more than encrypted computers: attackers gain access, move through systems, steal information, and compromise administrative accounts before ever encrypting anything, creating operational disruption, data loss, recovery costs, legal obligations, and extortion demands all at once. For most companies, even a few days of disruption can be costly.
How to reduce the risk:
Ransomware defense requires multiple layers: strong endpoint protection, vulnerability management, MFA, restricted admin privileges, monitoring, network controls, reliable backups, and incident response planning. Most importantly, test your backups: having one is not the same as knowing you can recover from it, and I have seen that difference matter at the worst possible moment more than once. - Third-Party and Supply Chain Risk
Businesses increasingly rely on outside companies: IT providers, software vendors, cloud platforms, accountants, payment processors, contractors, and other partners. These relationships improve efficiency, but they also create additional paths into the organization. If a supplier with access to your data or systems gets compromised, the attacker gains an indirect route into your business.
How to reduce the risk:
Know which third parties have access to sensitive information or critical systems, limit that access to what is necessary, and remove it when it is no longer required. Consider cybersecurity when selecting vendors, not just functionality and price. - Too Much Access
As companies grow, employees and contractors accumulate access: new permissions when they join, more when they change roles, and the old ones rarely get removed. Eventually users have far more access than their job requires, and if one of those accounts is compromised, the attacker inherits all of it.
How to reduce the risk:
Apply the principle of least privilege. Employees should generally have access to what their role requires, not everything they might possibly need. Review access periodically, protect admin accounts carefully, and remove access quickly when people leave. - Cloud Misconfiguration
Moving to the cloud does not automatically make you secure: Microsoft 365, Google Workspace, AWS, and Azure provide strong security capabilities, but they still need to be configured correctly. Common problems include excessive permissions, weak authentication, publicly accessible information, and insufficient monitoring, and the risk grows as departments adopt new cloud tools without central oversight.
How to reduce the risk:
Review your cloud security configuration regularly. Know who has admin access, enforce strong authentication, review external sharing, remove unused accounts, and monitor important security events. - Shadow IT and Unapproved AI Tools
A newer challenge is the rapid adoption of applications and AI tools outside the normal approval process. An employee adopts an app without thinking about how company information gets stored. The same now applies to generative AI: employees may paste customer data, contracts, source code, or financial information into AI platforms without understanding what happens to it next. The technology itself is not the problem. The lack of visibility and governance is.
How to reduce the risk:
Set clear policies on which applications and AI tools employees can use, and what information should never go into unapproved services. I would avoid policies that simply prohibit everything. Give people an approved alternative and make it easy to use. - Lack of Detection and Response
Many businesses focus heavily on prevention, but no security control is perfect. The real question becomes: what happens when something gets through? If an account is compromised on a Saturday evening, will anyone notice? A tool generating alerts that nobody responds to provides limited protection.
How to reduce the risk:
Establish clear responsibility for monitoring and incident response, whether that is handled internally, through an external provider, or both. What matters is that someone is actually watching and knows what to do next. - Not Being Prepared for an Incident
Even well-protected businesses can experience incidents, and preparation changes the outcome. If your company discovered ransomware tomorrow morning, who makes decisions? Who contacts support? Would systems get disconnected, and would insurance or legal counsel need to get involved? Trying to answer all of that during an active attack wastes the time you need most.
How to reduce the risk:
Build a practical incident response plan. It does not need to be long, just clear on responsibilities, contacts, escalation steps, and first actions during a serious incident. Then actually test it.
Which Risks Should Your Business Address First?
Not every business has the same risk profile. A healthcare organization holding patient data faces different risks than a construction company or a technology firm. But most growing businesses should be able to answer:
- Is MFA enforced across critical systems?
- Are critical vulnerabilities identified and patched?
- Are company devices protected and monitored?
- Are backups working and regularly tested?
- Are administrative privileges controlled?
- Can suspicious activity be detected?
- Do employees understand phishing and payment fraud?
- Do we know which third parties have access to our systems?
- Do we know which cloud and AI applications employees are using?
- Do we have a plan for responding to a serious incident?
If several of those answers are unclear, that is usually where the conversation should start.
Focus on Risk, Not Fear
Cybersecurity discussions can easily get dominated by frightening statistics, and honestly, that rarely helps a business owner make a better decision. The goal is not assuming a catastrophic attack is imminent. It is understanding where the realistic risks actually are and reducing them systematically.
For most businesses, a strong strategy does not require buying every available product. It requires getting the fundamentals right: identities protected, devices secured, critical vulnerabilities fixed, access controlled, backups that actually work, and someone watching for trouble. Get those in place, and the business becomes significantly harder to compromise and far better prepared for when something does go wrong.
Start With the Risks That Matter Most
Cybersecurity should not be driven by fear, or by whichever product is getting the most attention this year. It should be driven by actual business risk.
That is the conversation I would rather have with a growing business before they buy anything else: which risks could actually hurt you, and what is the fastest way to close those gaps.
The goal was never eliminating every possible cyber risk. It is making sure the risks that could seriously affect your business are understood, reduced, monitored, and managed.
