Fortinet Firewall Breached: What Italian SMEs Risk

The attack on Fortinet firewalls: chronicle of an already known vulnerability

On June 17, 2026, TechCrunch reported News of global importance. A group of Russian-speaking cybercriminals has allegedly compromised tens of thousands of Fortinet firewalls and VPNs. The targets include large companies distributed worldwide. However, the most concerning data is not the scale of the attack: it's the method.

Criminals exploited known credentials, meaning passwords that were previously exposed or never changed. This is not a sophisticated zero-day exploit. Instead, it's an elementary technique applied on a large scale. This means the vulnerability doesn't lie within the Fortinet product itself, but in the credential management practices of system administrators.

Therefore, the risk perimeter expands enormously. It's not just multinational corporations with complex infrastructures that are at risk. Italian SMEs using Fortinet devices to protect their networks are also potentially exposed.

Why Italian SMEs cannot ignore this signal

Fortinet is one of the most popular network security vendors in the world. In Italy, Fortinet firewalls and VPNs are widely adopted by manufacturing companies, professional firms, retailers, and logistics companies. Therefore, the installed base is significant within the Italian productive fabric as well.

The structural problem is well-known: SMEs often purchase perimeter security devices and configure them only once. Subsequently, they rarely update the firmware or rotate access credentials. This behavior creates a permanent vulnerability window. In fact, default credentials or those leaked in previous breaches are easily found on the dark web.

In addition to this, many Italian SMEs have extended VPN access during and after the massive remote working phase of 2020-2022. Consequently, there are now active remote access points that are not monitored with due attention. Every unattended access point is a potential entry point for an attacker.

According to the analysis of Gartner on cybersecurity, identity and access management remains one of the most overlooked critical points in medium-sized organizations. Similarly, the McKinsey Global Institute most successful attacks exploit known vulnerabilities, not novel exploits.

The immediate impact on business operations

A compromised firewall is not just a technical problem. It is a direct threat to a company's business continuity. Through unauthorized access to the perimeter network, an attacker can move laterally within the infrastructure. Then, they can reach ERP systems, customer databases, accounting archives, and internal communication tools.

In particular, for Italian SMEs active in B2B, a breach of this type can have serious consequences. Business customer data is often covered by confidentiality agreements. Therefore, an information leak can result in reputational damage, loss of contracts, and potential GDPR penalties.

Despite this, many companies underestimate the risk until they experience a direct incident. This reactive approach is costly. According to industry estimates, the average cost of a data breach for a European SME exceeds €150,000, considering downtime, remediation, and business impact.

What to do now: priority actions for Fortinet users

The response to this type of threat does not require extraordinary investments. It requires operational discipline and a methodical review of existing configurations. Below are the most urgent actions.

• Immediate credential audit: Verify that no administrator accounts are using default passwords or credentials that have been exposed in previous breaches. Tools like HaveIBeenPwned can be a starting point.
• Firmware update: Fortinet regularly releases security patches. Check your installed version and apply available updates without delay.
• Review of active VPN connections: Disable all VPN accounts that are no longer needed. Every unused access is a residual risk.
• Enable Two-Factor Authentication (MFA): MFA drastically reduces the risk of unauthorized access, even if credentials are compromised.
• Access Log Monitoring: Implement an alerting system for anomalous access or repeated failed login attempts.

These measures do not replace a structured cybersecurity strategy. However, they represent the minimum acceptable level of protection for any SME handling sensitive data.

The construction site still open: safety as a process, not a product

The most common mistake that we at SHM Studio What we observe in Italian SMEs is treating cybersecurity as a one-time purchase. You buy the firewall, install it, and forget about it. On the contrary, security is a continuous process that requires periodic reviews, constant updates, and staff training.

In this context, the AI-driven digital transformation introduce new attack surfaces. Every new digital tool adopted—whether it's a cloud CRM, an API integration, or an automation system—expands the perimeter to be protected. Therefore, security must be integrated into the digital strategy from the design phase.

For SMEs investing in web presence e digital marketing, it's crucial that the underlying technological infrastructure is solid. A corporate website or a campaign Google Ads Someone who converts well is worthless if their internal systems are vulnerable to a breach.

Outlook: Cyber Risk for SMEs in the 2027-2028 Biennium

The projections for the next two years are not reassuring. The attack surface for SMEs will continue to expand. In fact, the growing adoption of SaaS tools, integration with e-commerce platforms, and the use of generative AI for internal processes multiply potential access points.

Furthermore, cybercriminal groups are becoming more organized and efficient. As highlighted by Wired Security, the professionalization of cybercrime has lowered the technical threshold required to conduct large-scale attacks. As a result, even SMEs—historically considered less attractive targets—are now in the crosshairs.

For this reason, investing in security skills and processes is no longer an option reserved for large companies. It is a competitive necessity for any company that wants to operate reliably in the digital market.
