SMBs facing today’s cyber threats
For a long time, many small and medium-sized business leaders believed that cybercriminals were mostly interested in large banks, multinational companies or government organizations. In 2026, that perception is not only outdated, it is dangerous.
SMBs have become prime targets for cyberattacks. Not because they hold less value, but because they often represent the best effort-to-reward ratio for attackers. Customer data, financial information, partner access, intellectual property: today’s SMBs have everything cybercriminals are looking for.
The reality is simple: the size of your business does not protect you. In many cases, it can make you more vulnerable.
Why do cybercriminals target SMBs?
Cyberattacks have evolved. They are no longer carried out manually by isolated individuals: they are now automated, industrialized and powered by artificial intelligence.
Criminal groups no longer need to choose a specific target. They scan the Internet for organizations with known vulnerabilities, compromised credentials or employees likely to fall for a fraudulent email.
According to Nicolas Côté, CISSP and Cybersecurity Practice Lead at Solulan:
“Attackers no longer break in. They are often invited inside because they use compromised legitimate identities. The battle is no longer only about the network, it is about digital identity.”
Several characteristics make SMBs especially attractive to cybercriminals.
1. Limited resources
Few SMBs have a dedicated cybersecurity team or a security operations centre running 24/7.
Updates may be postponed, security audits may be infrequent and advanced monitoring tools may be missing.
2. Increasingly complex IT environments
Hybrid work, SaaS applications, personal devices, external suppliers and artificial intelligence have significantly expanded the attack surface of small and medium-sized businesses.
Every new tool adopted to improve productivity can also create a new entry point for attackers.
3. A growing dependence on digital identities
Business applications are now accessible from the Internet. Microsoft 365 accounts, CRMs, ERPs, HR platforms and financial tools are all protected by credentials.
When these credentials are compromised, attackers can bypass several traditional controls and operate as legitimate users.
The real target in 2026: identity
For years, businesses focused their investments on firewalls and antivirus solutions. These controls remain important, but they are no longer the first line of defence.
Today, most successful attacks begin with the exploitation of a digital identity.
In a recent presentation by Nicolas Côté at ITSec, Quebec’s annual cybersecurity summit, he explained that identity offers attackers the best effort-to-gain ratio. With the widespread adoption of cloud services and Single Sign-On, one compromised account can provide access to several critical platforms.
Cybercriminals commonly use:
- AI-powered phishing
- Credential theft
- MFA fatigue attacks
- Fake login portals
- Social engineering
- Audio and video deepfakes
No matter the method, the result is often the same: the user believes they are performing a legitimate action while handing access to an attacker.
Why traditional MFA is no longer enough
For several years, multifactor authentication was considered a best practice every business needed to adopt.
It remains useful today, but some forms of MFA have become vulnerable to modern phishing techniques.
For example, SMS codes or apps that generate one-time passwords can be intercepted, redirected or manipulated through sophisticated phishing campaigns.
Microsoft has announced that passkeys will become the default phishing-resistant authentication method in Microsoft Entra ID, reducing reliance on methods that are vulnerable to phishing. Passkeys use public-key cryptography and are designed to resist credential theft attempts.
According to Nicolas Côté:
“In 2026, traditional MFA is no longer the final destination. Organizations need to move toward phishing-resistant methods such as passkeys, FIDO2 keys or Windows Hello for Business.”
In other words, the question is no longer: “Do you have MFA?” It is now: “Can your authentication resist modern attacks?”
The 5 most important cyber threats for SMBs in 2026
1. AI-generated phishing
Fraudulent messages have become nearly indistinguishable from legitimate communications.
Attackers use AI to personalize emails, imitate an executive’s tone or reproduce a supplier’s visual signature.
2. Ransomware
Even when the ransom is not paid, the costs associated with business recovery, system restoration and lost productivity can be significant.
3. Supply chain attacks
Cybercriminals target a less protected supplier in order to reach its clients.
An SMB can therefore become the indirect victim of an incident affecting a third party.
4. Microsoft 365 account compromises
Collaboration platforms have become one of the primary targets for attackers.
Once inside the environment, they can read emails, launch payment fraud attempts or steal sensitive data.
5. Data leaks related to AI tools
Employees increasingly use artificial intelligence tools to speed up their work.
Without proper governance, sensitive information can be shared with external platforms without the organization realizing it.
How can an SMB improve its cybersecurity?
A large-enterprise budget is not required to significantly improve an organization’s cybersecurity posture.
The most resilient SMBs usually focus on the following priorities.
1. Adopt a Zero Trust approach
Never automatically trust a user simply because they are on the internal network. Every access request must be continuously validated based on identity, device, risk level and sign-in context.
2. Deploy passkeys and phishing-resistant authentication
Passwords alone are no longer enough: the future of authentication is moving toward passwordless methods and FIDO2 standards.
3. Strengthen network security
Strong business network security relies on network segmentation, proactive MDR monitoring, XDR security, vulnerability management and periodic penetration testing.
4. Train employees regularly
Most incidents involve a human factor. Phishing simulations and continuous awareness training remain among the most effective cybersecurity investments for SMBs.
5. Test your incident response capability
An incident response plan is only useful if it has been tested. Every SMB should know exactly who to contact, what actions to take and how to restore operations before an incident occurs.
SMB cybersecurity is no longer just a technical issue
Business leaders sometimes still see cybersecurity as an IT-only concern. In reality, it has become a business continuity issue.
A successful attack can lead to operational downtime, revenue loss, reputational damage, legal obligations related to Law 25 and a loss of customer trust.
The good news is that many of the most common attacks can be prevented with the right strategy, modern controls and specialized support.
Protect your SMB before an incident occurs
Cybercriminals look for easy targets. Their goal is not necessarily to attack the largest organization, but the one that is least prepared.
At Solulan, our experts help SMBs assess their security posture, deploy modern solutions such as passkeys, strengthen identity protection, implement MDR/XDR monitoring and support Law 25 compliance.
We strongly believe that in cybersecurity, prevention remains the best defence.
