Do you need a VPN, a Firewall, or both?
Protecting your IT assets against threats is an essential part both of business and personal digital activities. Firewalls and VPNs are two common security tools that can help reduce risk and maintain usability. IT communications can be encrypted and filtered when used together.
But, do you really need both? Is one better than the other? These are the questions we’ll answer below.

The State of Internet Security
The internet is essential for our daily work and personal lives. Many people are online 24/7, whether they use a smartphone or a personal laptop.
The online world is not safe if you aren’t prepared. It is no longer possible to be anonymous online and become a target for hackers or attackers. Today, every action online can put you at risk of interception, spoofing, impersonation, hijacking, attacker-in-the-middle, account takeover, malicious code infection, and much more.
There are many options available for large organizations as well as small office/home office environments (SOHO) environments. These options can significantly reduce online risks. These options include deploying a VPN or firewall.
What is a VPN?
A virtual private network (VPN), is an encrypted network or Internet connection that encrypts all communications between your local device, and a trusted remote device or service.
A VPN is a digital or electronically re-creation (or electronic re-creation) of a physical world concept. It is the idea of a dedicated, isolated physical network cable that you can only use and access.
VPNs are a virtual cable that wraps up, encapsulates, or contains standard insecure network communications. This tunneling protocol encrypts the transmitted content. Although VPN communications are protected over the same network paths as regular traffic, the payload is encrypted so that it can be used to create a virtual isolated cable.
What are the benefits of a VPN?
A VPN has many benefits:
Encryption provides improved communication security
Remote control and remote access are secured
In some cases, anonymity services
Masked client or origin IP Address
Blocking attacks by local (physical, and logical) attackers
There are many other benefits to VPNs. VPNs can improve network throughput in some cases. This could be due to streamlining communications, eliminating ancillary protocols and resource-wasting communications. Cost savings can also be realized by some organizations, primarily due to a reduction in recovery and repair costs from compromises caused plain-text communications.
The Different Types Of VPNs
There are three main types:
Transport mode host-to-host
A transport mode host to-host VPN establishes a secure connection between two systems. Only the payload of such a VPN is encrypted. The headers of protocol packets that guide communication across the intermediary network remain in their original plain text form.
The contents of a transmission are protected but the identities of the people communicating are exposed. This VPN is used in private networks where there is a high level of trust, but where additional protection is required for specific host-to–host communications such as periodic backups or database replication.
Tunnel mode site-to-site
Tunnel-mode site to-site VPN allows for secure connections between two networks or physical locations. Both the payload and original packet headers are encrypted in such a VPN. To direct communication between the VPN ends, a tunnel header is added. Only two systems can communicate with each other.
