Nowadays, protecting data and network infrastructure is a key part of any company’s strategy. Many organizations face a dilemma: is it better to bet on a firewall or a VPN for comprehensive security? Both solutions have their unique advantages, but their application varies depending on the needs. In this article, we explain how firewalls and VPNs work, what differences they have, and in which situations they will work best.
Key findings:
- Firewalls protect networks from external threats by filtering traffic and blocking unauthorized connections.
- The VPN provides a secure connection to the network, protecting data from interception.
- A combination of both solutions, such as Opswat MetaDefender, provides comprehensive cyber security.

What is a firewall and how does it work?
A firewall is a network security system that monitors and controls incoming and outgoing traffic on a network. It acts as a barrier between trusted networks and potentially dangerous external sources. A firewall analyzes data packets and decides which ones can pass through and which ones will be blocked, based on set rules. In companies, firewalls are used to protect internal networks from threats from the Internet. They protect against unauthorized access, hacking attacks and malware. Modern solutions such as Opswat MetaDefender, offer advanced traffic filtering and analysis to effectively protect corporate data from external threats.
What does a VPN offer and why is it important?
VPN (Virtual Private Network) is a technology that creates an encrypted connection between a user’s device and the network. This protects data transmitted between the user and the network from interception by third parties. VPN is especially useful for remote work, when employees connect to the company’s network from different locations. A VPN also protects user privacy by hiding the user’s IP address and location. In companies, a VPN enables secure data transfer between departments or when working from home. Good VPN solutions, such as those offered by Opswat cyber security, guarantee high levels of encryption and connection stability.
Firewall vs. VPN – key differences and applications
- Scope of protection:
Firewall focuses on protecting the network by filtering traffic and blocking potential threats from the Internet. A VPN, on the other hand, protects data transmitted between you and the network by ensuring that it is encrypted. - Application:
Firewall is best for protecting internal corporate networks, while VPN is indispensable for remote work and for transferring data between locations. - Cost and complexity:
Firewalls often require more advanced configuration and network integration, which can be costly. VPNs are easier to implement, especially for small businesses. - Effectiveness:
While both solutions are effective in their respective fields, neither offers complete protection on its own. In combination, they provide comprehensive network and data security.
Why combine the two solutions?
The combination of firewall and VPN is the best way to ensure comprehensive cyber security. The firewall protects the network from external threats, while the VPN ensures the secure transmission of data. This allows companies to effectively protect their resources both inside and outside the network. Solutions such as Opswat MetaDefender integrate firewall and VPN functions to offer multi-layered protection. This allows companies to not only protect their data, but also ensure the security of employees using remote work.
Frequently asked questions
Can a firewall and VPN work independently?
Yes, but the combination of both solutions provides more comprehensive protection against threats.
Which solution is better for a small business?
For small businesses, a VPN may be more accessible and easier to implement, but a firewall offers a higher level of network protection.
Does a VPN protect against malware?
A VPN protects data from interception, but is not designed to detect malware. For that, you need a firewall.
