A VPN and a firewall each protect your online security but in different ways. A VPN hides your IP address and encrypts your internet traffic, keeping your browsing private. In contrast, a firewall monitors and controls incoming and outgoing data on your device, blocking unwanted or suspicious connections to keep hackers and malware out.

Pairing them up is like locking your doors and closing the blinds — you get privacy and protection all at once. A VPN keeps your browsing hidden, while a firewall acts as a shield against intruders. This combo is a smart way to protect your privacy and secure your devices if you’re handling sensitive information or just want a safer online experience.

After testing over 50 VPNs, ExpressVPN is my top recommendation for safe online activity. It offers military-grade encryption and ad, malware, and tracker blockers. Plus, thanks to its reliable worldwide servers, you can safely access the content you need from anywhere. Better yet, it’s possible to try ExpressVPN risk-free, thanks to its 30-day money-back guarantee.

What is a VPN?

A VPN (virtual private network) helps boost your privacy and security while you’re online. When you connect to a VPN, it sets up an encrypted tunnel between your device and the internet, so snoops can’t read your data — a handy feature if you’re using public WiFi or just want a more private browsing experience.

On top of that, a VPN hides your IP address, making it tougher for websites, advertisers, and other users to follow your online movements. Whether you’re checking your bank account on public WiFi or streaming at home, a VPN offers you more control over who sees what you do online.

Types of VPNs

With so many types of VPNs out there, finding the right one can be tricky. Each type has its own strengths and works best in different situations. Here’s a quick guide to help you pick the one that best suits your needs:

What is a Firewall?

If you’re looking to prevent unwanted access to your computer or network, a firewall could be just what you need. Firewalls act like digital gatekeepers, keeping out hackers, malware, and other suspicious traffic. They work by filtering data and blocking anything that doesn’t meet specific security criteria.

Essentially, firewalls inspect the data flowing through your network and decide whether to let it pass based on the level of security you’d like to maintain..By analyzing traffic at different layers, they allow safe communication while preventing malicious traffic from getting in and exploiting your system.

Types of Firewalls

Different firewalls provide different levels of security, depending on your needs. Here’s a quick guide to the types available and what each one is best for:

  1. Packet-filtering firewall. This type looks at individual data packets and blocks or allows them based on preset rules. It is ideal for lightweight protection on smaller networks.
  2. Stateful inspection firewall. Tracks active connections to decide which packets to let through, providing stronger security for medium to large businesses.
  3. Proxy firewall (application-level gateway). Acts as a middleman between users and the internet, filtering traffic at the application level. It is great for organizations that need to hide internal networks from outside threats.
  4. Next-generation firewall (NGFW). Adds extra features like intrusion prevention and application awareness to stop advanced attacks, making it ideal for enterprises needing high-level security.
  5. Unified threat management (UTM) firewall. Combines a firewall with antivirus, VPN, and other security features, offering an all-in-one solution for small to medium businesses.
  6. Cloud firewall. Hosted in the cloud to filter traffic for cloud-based setups, this is best for businesses with a heavy cloud presence that want scalable security.
  7. Circuit-level gateway. Operates at the session layer, verifying session legitimacy for added security.
  8. Network address translation (NAT) firewall. Conceals your network’s IP addresses, adding an extra layer of security.
  9. Host-based firewall. Software installed on individual devices, providing device-specific protection.
  10. Hardware firewall. A physical device placed between a private network and the internet to monitor and filter network traffic. It offers robust protection for entire networks without consuming host resources. Best for businesses requiring high-performance security for their entire network infrastructure.

Benefits of Using a Firewall

A firewall is a crucial tool for protecting your network and keeping your data safe. Here are the key benefits:

  • Blocks unauthorized access. A firewall prevents hackers and malicious entities from accessing your network, addressing concerns about cybercriminals infiltrating your system.
  • Monitors and filters traffic. It screens data going in and out, blocking harmful traffic and allowing safe data. This helps solve the issue of unwanted traffic entering your network.
  • Prevents malware and virus infections. Firewalls stop malware, viruses, and harmful software, protecting your system from potential infections and data breaches.
  • Enhances network security. Acting as a barrier between your network and external threats, firewalls boost overall security, which is crucial for keeping your system safe.
  • Protects personal and business data. By blocking unauthorized access, firewalls secure sensitive information, helping prevent data breaches or leaks.
  • Gives control over network traffic. A firewall lets you manage who and what can access your network, offering much-needed control over network security.
  • Supports compliance. Firewalls help meet industry regulations for data protection, ensuring that your system complies with legal requirements for security.
  • Bandwidth management. Some firewalls offer features to regulate and supervise bandwidth usage, helping optimize network performance.
Pro Tip: Now you know the difference between VPNs and firewalls. Next, check out VPN vs antivirus and VPN vs proxy to see how these tools stack up.

How to Install a Firewall on Your Device

A firewall monitors traffic, allowing only trusted connections so you can control who accesses your system. One big advantage is that most platforms come with a built-in firewall, providing straightforward security without needing extra software.

Important: Built-in firewalls are enough for most individuals and home networks, so third-party firewalls are usually unnecessary unless you need advanced features. Software firewalls offer basic protection but may struggle with larger or more complex networks. For businesses or advanced security needs, a hardware firewall is ideal, as it provides stronger, more comprehensive protection across multiple devices.

VPN vs Firewall: Key Differences

The biggest difference between a VPN and a firewall lies in their primary function. A VPN focuses on protecting your online privacy by encrypting your data and masking your IP address. Plus, it secures your internet connection, especially on unsecure public networks.

On the other hand, a firewall is designed to protect your network by filtering traffic and blocking unauthorized access.

Both tools are essential for securing your digital activities, but they address different aspects of protection. Here are other key differences between a VPN and a firewall:

Key Aspects VPN Firewall
Primary Function Encrypts data to protect privacy and provide security Monitors and blocks unauthorized network access
Focus Protects data in transit and secures connections Secures the internal network from external threats
Traffic Control Routes and hides internet traffic through secure servers Filters incoming and outgoing network traffic
Data Encryption Provides end-to-end encryption for internet connections It doesn’t encrypt data, focusing on traffic control (however, some advanced firewalls, like Next-Generation Firewalls, can include encryption capabilities for certain types of traffic)
Usage Scenario Ideal for securing public Wi-Fi and remote access Used for protecting networks from external attacks
Scope Hides IP address and location Blocks specific IP addresses, ports, or protocols
Target Users Used by both individuals and businesses, depending on their specific needs Used by both individuals and businesses, depending on their specific needs
Implementation VPNs are usually software-based and can be installed on individual devices Firewalls can be both software-based (installed on devices) or hardware-based (physical devices that protect entire networks)

Factors to Consider When Choosing a VPN or Firewall

I have gathered a few key factors to help you choose the right option based on your situation:

  • Privacy protection. If you want to keep your online activity private by hiding your IP address or blocking tracking, a VPN is the best fit.
  • Network security. Firewalls are crucial for blocking unauthorized access and protecting your network from potential threats. However, a VPN adds an extra layer of security by encrypting all data you send, which is helpful for secure communication.
  • Public WiFi usage. For anyone who uses public WiFi often, where security risks are higher, a VPN encrypts your data, keeping your connection secure.
  • Accessing restricted content. If you need to bypass region restrictions on certain sites, a VPN is your go-to option.
  • Malware and intrusion prevention. While some VPNs offer ad-blocking and malware protection, firewalls are typically more effective at blocking malware and preventing intrusions.

Tips for Having a Safe Browsing Experience

Browsing the internet can expose you to privacy and security risks if precautions aren’t taken. Here are some practical tips to keep your browsing safe and protect your data:

  • Use strong, unique passwords. Create complex passwords unique to each account. Reusing the same password across sites is risky — if one account is compromised, all your accounts could be vulnerable.
  • Keep your software and browser updated. Regularly update your browser and security software to patch security vulnerabilities. Ignoring updates leaves your system open to malware and other security issues.
  • Enable two-factor authentication (2FA). Adding 2FA provides an extra layer of security beyond passwords alone. This reduces the likelihood of unauthorized access even if your password is compromised.
  • Use a VPN on public networks. When using public WiFi, a VPN helps secure your connection by encrypting your data. Avoid connecting without one, as hackers often target unsecured public networks.
  • Be wary of phishing scams. Always verify links and attachments, even from familiar sources. Phishing scams are common and can lead to data theft if you unwittingly click on harmful links.
  • Download files only from trusted sources. Stick to reputable sites for downloads to avoid malware, which often hides in pirated software or unofficial apps.
  • Check for HTTPS. Only enter sensitive information on HTTPS sites, as they indicate a secure connection. Using HTTP sites can expose your data to potential theft.
  • Clear cookies and cache. Regularly clearing cookies and cache limits tracking and reduces the risk of data exposure. Most users overlook this, allowing sites to track their activities.
  • Turn off autofill. Autofill can make it easy for anyone who gains access to your device to see sensitive information. Consider turning off this feature for an added layer of security.
  • Delete saved passwords. Avoid saving passwords in your browser, especially on shared devices. Using a password manager offers safer storage for credentials.
  • Consider using a sandbox. Running unknown or high-risk programs in a sandbox isolates them from your system, reducing the risk of malware spreading across your device.

Your chosen VPN should also be compatible with multiple operating systems. This helps you stay secure and private, irrespective of the device you’re using to stay online. Here’s a list of the best VPNs for different devices:

FAQs on VPN vs Firewall

Do I need a firewall if I have a VPN?

Yes, you still need a firewall, even if you have a VPN. A VPN encrypts your internet traffic, ensuring privacy, but a firewall protects your device and network from unauthorized access and malicious traffic. They serve different purposes and work best together.

Can a VPN bypass a firewall?

Yes, a VPN can bypass certain firewalls, especially if they’re not specifically set up to block VPN traffic. However, more advanced firewalls can detect and block VPNs by identifying specific traffic patterns. Knowing how to set up and configure a VPN effectively can improve your chances of getting around these restrictions, but it may not always work if the firewall is sophisticated.

Should the VPN server be before or after the firewall?

The VPN server should typically be placed after (behind) the firewall. This configuration provides better security by allowing the firewall to monitor and control VPN traffic. The firewall can be set up to allow only VPN traffic to reach the VPN server, adding an extra layer of protection.

While there are scenarios where placing a VPN server in front of a firewall might be necessary, the behind-the-firewall placement is generally considered more secure and manageable for most organizations.

Should I use a VPN with a firewall and an antivirus?

Yes, using a VPN with a firewall and antivirus provides the most comprehensive protection. A VPN secures your connection, a firewall blocks unauthorized access, and antivirus software detects and removes malware, together creating a comprehensive security setup.

Is it a good practice to combine NAT, a firewall, and a VPN?

For larger organizations, isolating NAT, firewall, and VPN functions is preferred for enhanced security, performance, and ease of management. This approach allows each service to be managed, updated, and monitored separately, reducing potential points of failure and minimizing security risks. It also ensures that reboots or maintenance on one service don’t disrupt others.

However, for individual users or small networks with limited resources, combining these functions into a single device or VM can be practical and convenient, particularly if configured with strong security settings. Using a reliable VPN like ExpressVPN in this setup provides an extra layer of encryption without the need for a separate device.

To summarize, these are the best VPNs for secure online activity…
