Is a stolen password the biggest security risk? Unfortunately, that’s not the case anymore. Generative AI capabilities have made cybersecurity blind spots more obvious. In 2026, hackers are exploiting system vulnerabilities to target mobile-based entry points using phishing links.
According to Verizon Business’s 2026 Data Breach Investigations Report, 31% of all breaches start with some type of software vulnerability.
That makes basic defenses like strong passwords and multi-factor authentication important, but no longer enough on their own. As attack techniques get more sophisticated, the gaps between your software, devices, employees, and security controls can become easy entry points for attackers.
The financial stakes are also high. IBM’s latest Cost of a Data Breach Report puts the average cost of a data breach at $4.99 million globally and $11.5 million in the U.S. As a small business, how do you minimize small business risk? Let’s take a look at what the data says about cybersecurity solutions for small businesses.
Multi-Factor Authentication Vs. Modern Threats
Multi-factor authentication (MFA) should be a non-negotiable layer of protection for every small business – but it’s not a silver bullet. July’s high-profile breaches showed why. Attackers are increasingly getting in through valid credentials, compromised vendor accounts, third-party platforms, and legacy systems that can look legitimate to traditional security controls.
These breaches show that hackers increasingly use previously compromised access. In one case, malicious activity targeting a single employee exposed nearly 7 million U.S. driver’s license numbers. Other incidents involved attackers accessing customer tax documents through a third-party IT platform and exfiltrating data from a healthcare software environment.
For small businesses, that means cybersecurity has to go beyond multi-factor authentication and password policies. Understand which vendors and applications can access it. Limit access to only what people and systems actually need. And wherever possible, owners must protect the data itself with controls such as encryption and tokenization.
How Do The Scammers Get In?

As employees get better at spotting suspicious emails, fake login pages, and obvious phishing links, attackers are shifting their attention to a channel people often trust more: their phones. Verizon’s 2026 Data Breach Investigations Report found that mobile-centric social engineering attacks are becoming more effective, with success rates 40% higher than traditional email phishing.
That means the scam could show up as a text from “your bank,” a call from someone pretending to be your IT provider, or a message asking you to urgently approve a payment.
Phishing is the biggest risk
The biggest cybersecurity risk for small businesses (43.4%) is phishing and email scams. But what is a phishing scam? A phishing scam is a trick cybercriminals use to access sensitive information through authentic-looking links. Scammers usually do this through fake text messages and emails that appear to come from a trusted source. These messages use panic, anxiety, or urgency to make people click a link or open an attachment.
How to spot a phishing email?
A phishing email is a malicious or deceptive email designed to take you to a fake website, capture your credentials, download malware, or trigger another malicious action. It may look legitimate at first glance, using familiar branding or a URL that closely resembles a trusted company.
How to spot a phishing link? Don’t judge a link by how professional the message looks. On a computer, hover over it; on a mobile device, inspect the destination before tapping. Be especially cautious when the message creates urgency, asks for credentials, requests a payment, or comes from an unexpected sender.
Beware of vishing
Vishing is phishing over the phone. Instead of sending a suspicious link, scammers use a convincing voice, a fake identity, or an urgent business scenario to pressure someone into revealing information or taking action.
A caller might claim to be from your bank, software provider, IT team, or even your CEO. The request may sound completely reasonable, but the pressure is the red flag.
Remember this simple rule to avoid such scams. Never verify a high-risk request through the same channel that delivered it. If someone calls asking for a password reset, payment, MFA approval, or sensitive information, hang up and contact the person or organization through a known, trusted number.
Third-party IT vendors
Your business doesn’t have to be the direct target for your data to be exposed. Third-party vendors, IT providers, SaaS platforms, and other partners may have access to your systems or sensitive information.
Verizon’s 2026 DBIR found that breaches involving third parties increased 60%, with third-party involvement now appearing in 48% of breaches.
For an SMB, that means cybersecurity can’t stop at your own network. Know who has access to your data, what they can access, and what security controls they have in place. If you’re not careful, your vendor’s security practices can become your security risk.
Your phone is the new entry point
This is where SMBs need to pay attention. Smishing or phishing delivered through text messages and vishing, or voice phishing, are becoming increasingly attractive to attackers.
As people become better at recognizing traditional phishing emails, threat actors are moving toward mobile-centric attacks, including fake texts and phone calls.
And mobile attacks have an advantage – they feel extra personal and immediate. An employee may ignore a suspicious email at their desk but respond to a text that appears to come from their boss, bank, delivery service, or IT provider.
AI is also making these scams harder to spot. Attackers can create more convincing messages and impersonations at scale, rendering the old advice of “just look for bad spelling” far less reliable.
AI-led cybersecurity risks
As AI capabilities advance faster than people can keep up, hackers are also using the tool to exploit security flaws. Model inversion, data poisoning, privacy leakage, API and backdoor attacks are some of the concerning threats posed by generative AI technology.
If an AI is trained on proprietary information, model inversion can be used to access it. Data poisoning involves modifying an AI’s capabilities to produce incorrect predictions or choices. This is a subtle attack; however, if left undetected, it could pose a serious risk to a company. Privacy leakage occurs when the sensitive data used to train the AI model is leaked.
The information contained within could range from trade secrets and employee details to personal data. A backdoor attack embeds a malicious backdoor in an AI model during training. This backdoor could be triggered by a specific input that leads the model to behave erratically.
The Best Cybersecurity Solutions For Small Businesses
Cybersecurity measures vary by industry.
But mostly, cybersecurity solutions include disaster recovery backups, spam filtering, access control for G Suite apps, and regulatory monitoring of AI tools. From multi-factor authentication to information management best practices, here are solutions a small business can adopt to protect itself from cyberattacks.
Enabling multi-factor authentication
If you’re looking for one of the best cybersecurity solutions for a small business, start with multi-factor authentication (MFA).
Passwords are no longer a strong enough line of defense on their own. Employees can fall for phishing attacks, credentials can be stolen in a data breach, and passwords can be reused across multiple services. MFA adds another verification step before someone can access an account, so even if an attacker gets the password, they still need the second factor.
For an SMB, that extra layer can make a major difference. CISA recommends that small and medium-sized businesses require MFA wherever possible, particularly for email, file storage, remote access, financial systems, and administrative accounts. CISA specifically recommends stronger options such as security keys and FIDO/WebAuthn-based authentication, which are designed to resist phishing.
Where should SMBs start?
Don’t try to secure everything at once. Prioritize the accounts that would cause the most damage if compromised:
- Banking and financial accounts – protect anything that can move money or access financial information.
- Business email – Attackers can use a compromised inbox to reset other passwords, impersonate executives, or send fraudulent payment requests.
- Cloud storage – Google Drive, Microsoft 365, Dropbox, and similar platforms can contain contracts, customer information, employee records, and intellectual property.
- Remote access and VPNs – Particularly important for employees and IT providers accessing systems from outside the office.
- CRM and customer databases – These can contain valuable personal and business information.
- Administrator accounts – These should receive the strongest authentication controls because they can potentially unlock much of your environment.
CISA’s current guidance recommends starting with administrators and employees who handle sensitive information, then expanding multi-factor authentication across the organization.
Information mismanagement
Information mismanagement occurs when a business fails to properly handle, protect, or store its data due to disconnected tools, incorrect data entry, or unclear data policies.
For SMBs, unstructured data in the form of PDFs, emails, and customer feedback can lead to mismanagement without an effective strategy.
Tool sprawl can make the problem worse. The CSA Official Press Release found that 32% of organizations use 11 or more tools to manage unstructured data, creating fragmented ownership and inconsistent security controls.
And AI is adding another layer. Employees are increasingly using AI tools to summarize documents, analyze customer information, draft proposals, and speed up everyday work. Without clear rules, employees can copy sensitive information into an AI application the business hasn’t properly assessed or approved.
Data security management
Data security management is one of the best cybersecurity solutions for small businesses. It’s the practice of protecting data from unauthorized alteration, access, or removal. The core principles guiding data security management are availability, confidentiality, and integrity.
A 2026 National Cybersecurity Alliance survey of 1,000 SMB leaders found a confidence gap between perceived cybersecurity readiness and actual preparedness. The research also highlighted that having security tools doesn’t necessarily mean businesses use them correctly. For an SMB, data security management should therefore focus on a few fundamentals:
- Give employees and vendors access only to the information they actually need. Use strong authentication and multi-factor authentication for critical systems.
- Encryption can help ensure that stolen or intercepted information is harder to use. Back up critical business data and make sure you can actually restore those backups.
- Your CRM provider, payroll company, cloud-storage platform, IT provider, and other third parties may have access to sensitive information. Understand what they can access and what security controls they have in place.
- Software vulnerabilities are increasingly being exploited by attackers, making patching and updating a business priority and not just an IT task.
Assume that something will eventually go wrong. Know who is responsible for responding, what systems to restore first, and how you’ll communicate with employees, customers, and vendors.
Best Antivirus Software for Small Businesses
Alongside multi-factor authentication, look into the following best antivirus software for small businesses –
- Bitdefender (Plans starting from $2.91/m).
- Norton (Plans starting from $3.33/m).
- McAfee (Plans starting from $3.33/m).
- Surfshark (Plans starting from $2.49/m).
- Aura (Plans starting from $3/m).
Final Takeaway
Multi-factor authentication is powerful, but it isn’t a complete cybersecurity strategy.
Attackers are increasingly targeting employees through phishing, smishing, vishing, and other forms of social engineering. An employee who unknowingly approves a fraudulent authentication request can still put an account at risk. That’s why MFA should work alongside employee security awareness, strong passwords, phishing protection, access controls, software updates, and regular monitoring.
For most SMBs, that’s one of the highest-value security improvements they can make without building a massive cybersecurity operation. And if your business still relies primarily on passwords, MFA is a good place to start.
