Engineers rarely stay stuck at a desk. They access industrial systems from home, hotels, worksites. Sometimes, from completely different countries. This changed everything — including the risks.
According to the Cybersecurity Ventures report, cybercrimes are expected to cost the world about $10.5 trillion per year by 2025. A significant portion of these attacks targets poorly protected remote connections.
What’s at Stake
Automation systems, SCADA, supervisory systems, PLCs — these environments were designed to operate on closed networks. When an engineer connects remotely without adequate protection, it opens a window to the outside world.
And this window can be found.

Newly hardened volcanic lava looked like a lifeless desert, but microbes arrived almost immediately and revealed a powerful clue about how to search for life outside Earth.

Brazil’s extended May Day holiday triggers a weather alert: a polar cold front associated with a large extratropical cyclone could reach the South with strong storms, wind gusts, a sharp drop in temperature, and accumulated rainfall of up to 100 mm, while other regions remain under intense heat on the same weekend.

Robots were placed in the depths of the ocean and discovered why Antarctica’s ice is melting non-stop.

In China, drones with high-pressure hoses are going up where firefighters cannot reach to extinguish fires in dangerous skyscrapers.
A survey by IBM Security indicates that the average cost of a data breach reached $4.45 million in 2023. For industrial sectors, the numbers are even higher — because the damage goes beyond data: it can shut down an entire plant.
VPN for Engineers: More Than Privacy
The acronym VPN (Virtual Private Network) is not new. But many people still associate the tool only with the privacy of the common user. For engineers, the role of VPN goes far beyond that.
The VPN for engineers works as an encrypted tunnel between the professional’s device and the company’s network. Everything that passes through there — commands, files, credentials — is protected from interception.
Encryption: The Layer that Makes the Difference
Without VPN, data travels over open networks like airport or hotel Wi-Fi with virtually no protection. Anyone with basic packet capture tools can intercept the traffic.
With an active VPN, this traffic is encrypted with standards like AES-256 — the same used by governments to protect classified information. It’s not just a technical feature: it’s the difference between a secure connection and an exposed vulnerability.
VPNs, Cybersecurity, and Free Access to External Resources
There is another important aspect that many companies overlook. Engineers working on international projects or needing to access technical documents hosted on foreign servers often dodge regional blocks.
Tools like VeePN allow you to bypass these geographical restrictions securely, combining data protection with free access to the global internet. The VeePN VPN is suitable both for accessing your home Netflix library from abroad and for those who need a VPN for Argentina when working on projects in Latin America. This is especially relevant in multinational project engineering, where access to repositories, supplier platforms, and remote systems in different countries is part of the routine.
Secure Remote Access: How It Works in Practice
Imagine an automation engineer who needs to access the supervisory system of a petrochemical plant from a notebook at home. Without VPN, this connection goes through the open internet.
With VPN for secure remote access, the process works like this: the engineer activates the VPN client, which authenticates the user and establishes an encrypted tunnel with the company’s server. Only then is access to the internal system granted. Any interception attempt along the way finds only encrypted data, useless without the correct key.
Protocols: Which to Choose?
Not all VPNs are the same. Protocols determine the speed and security level of the connection.
WireGuard is newer, faster, and also robust — ideal for those who need performance without compromising protection. On the other hand, IKEv2/IPSec is excellent for mobile devices, as it automatically reconnects when the network changes.
Risks of Not Using VPN
“Man-in-the-middle” attacks are one of hackers’ favorites on public networks. The attacker positions themselves between the engineer and the server, silently intercepting everything.
There is also the risk of session hijacking: the attacker captures authentication tokens and takes control of an active session. In industrial systems, this can mean unauthorized commands sent directly to physical equipment. The result can be catastrophic.
Corporate VPN vs. Individual VPN
Medium and large-sized companies usually maintain their own VPN infrastructure — dedicated servers, access policies by profile, audit logs. This is ideal.
But projects designed or from smaller companies often need an individual solution. In this case, choosing a reliable provider makes all the difference. When looking for a secure VPN, it is essential to check the no-log policy, available protocols, and connection stability. These characteristics determine whether a tool truly protects or just gives a false sense of security.
Compliance and Regulations
In Brazil, the LGPD (General Data Protection Law) requires companies to adopt appropriate technical measures to protect personal data. Engineers dealing with customer data, industrial plants, or critical infrastructures are directly subject to these obligations.
Internationally, standards such as IEC 62443 — specific for security in industrial automation systems — explicitly recommend the use of encrypted channels for remote access. Ignoring this is not just a technical risk: it is a legal exposure.
Best Practices for Engineers
Some simple rules make a big difference in daily life:
- Never access critical systems over public Wi-Fi networks without an active VPN.
- Regularly update the VPN client — vulnerabilities are constantly discovered.
- Always combine VPN with strong passwords and MFA.
- Use VPNs with modern protocols, not legacy solutions like PPTP.
- Document remote accesses made — in case of an incident, the history is essential.
Remote access security is not a secondary technical detail. It is a fundamental part of modern engineering.
The VPN for engineers is a concrete, proven, and accessible tool — it protects communications, ensures regulatory compliance, and drastically reduces the attack surface. In a sector where a failure can stop a plant, bring down a system, or compromise sensitive data, not using a VPN is a risk simply not worth taking.
