If you’re asking the question, what is a good VPN? Your starting point with this is understanding how VPN and surrounding options work. Virtual Private Networks (VPNs) secure remote access to business resources through encrypting data that’s transmitted over the internet.
Sounds simple enough, but the reality is this security measure doesn’t have as strong of a security posture on its own. Between SSL VPN, IPsec VPN, and the more modern solution Zero Trust Network Access (ZTNA), this article makes sure you understand the ins and outs.
Key Takeaways:
- A good VPN encrypts remote user traffic and connects them securely to business resources without exposing the full network
- SSL VPN and IPSec VPN serve different use cases, and knowing which fits your environment is the first decision to make
- VPN firewall integration matters, as a standalone VPN without firewall-level inspection leaves blind spots on the network
- Business size and user count have a direct impact on which VPN solution is the right fit
- ZTNA is replacing traditional VPN for many modern organizations

What Makes a Good VPN Solution for Business?
In the realm of VPN for business use, what makes it a good option has a lot to do with how it’s set up and managed. Between defining access permissions and integrating with next-gen firewalls (NGFWs), and more, there’s more to consider here than the VPN itself.
Below are a few surface-level examples of what ties into VPN management:
- Access permissions need to be defined to ensure employees only have access to what they need
- Integrate VPN traffic inspection with threat prevention to help detect suspicious connections
- Schedule regular firmware updates for VPN-supported firewalls and other related network equipment
- Track any expiration dates and renew certificates and licenses to avoid security gaps or issues with network access
These points are relevant whether it’s a small business VPN or those dealing with a much bigger infrastructure. From there, you’ll navigate the types of VPN solutions that are out there, and this heavily sways between SSL VPN and IPSec VPN.
SSL VPN vs IPSec VPN and Which One Your Business Needs
At their core, SSL VPN and IPSec VPN differ in how they establish connections. This also goes for how they provide access and support other business network requirements.
More than anything else, I’d tell you that companies should compare both options against your connectivity requirements. Between your existing network infrastructure, growth plans, and even industry compliance, they can play a pretty big role in the right decision here.
What is an SSL VPN for Business Use?
As far as business VPN solutions go, the whole scope of SSL VPN is pretty easy to grasp. It supports remote access to internal business apps. This could be done through a web browser, depending on the implementation of it.
Nevertheless, it can eliminate dedicated client software requirements for browser-based deployments. Moreover, it’s a pretty standard accommodation for remote teams that connect from a range of business or personal devices.
What is an IPSec VPN?
With IPSec VPN, you’re dealing with established encrypted connections at the network layer. It protects IP traffic between endpoints and generally requires dedicated client software for individual remote users.
However, site-to-site deployments tend to use compatible network devices. One thing I want to make sure to highlight here is the reality of careful configuration. Angles like authentication, routing, and access rules need careful configuration to guarantee secure and reliable connections at all times.
Choosing the Right Business VPN Solution by Size
If you’re looking for a starting point in your decision-making, you’ll find it across several key categories. Look into important details like your device count, overall network complexity, and currently available IT resources.
Whereas a small business might do just fine with SSL VPN, the tone starts to change as your operation grows. The table below gives a quick overview, as it breaks down how to choose the right VPN solution based on business size.
| Business Size | Recommended VPN Type | Key Consideration |
|---|---|---|
| Small (under 50 users) | SSL VPN | Low overhead, easy management, browser-based access |
| Mid-Market (50 to 250 users) | SSL or IPSec | Centralized VPN management becomes critical at this scale |
| Enterprise (250+ users) | IPSec or ZTNA | Consider whether traditional VPN still fits the architecture |
Keep in mind these are general suggestions, and the conversation surrounding ZTNA is changing the way modern businesses look at SSL VPN. I can agree that VPNs still have their place in the world, but modern businesses shouldn’t rely solely on them for secure remote connections.
When to Consider ZTNA Over a Traditional VPN
Traditional VPNs can provide access to broad network resources. However, with ZTNA, this limits connectivity to specifically authorized apps and services. Overall, it’s more granular security, which definitely doesn’t hurt in the age of AI-driven security threats.
Keep these points in mind when navigating VPN, firewall, or standalone business solutions:
- ZTNA verifies users and devices before granting access, while applying policies to individual resources
- A growing remote workforce, increasing management demands, and credential-based security needs are all signs you need ZTNA
- Businesses working with multiple offices or cloud environments should look at ZTNA as a must-have
A leading example of a ZTNA solution that’s easy to integrate is SonicWall’s Cloud Secure Edge (CSE). Of course, this is just one of many, but it goes to show that top security manufacturers have already made it easy to integrate with existing network security infrastructure.
Final Thoughts
In your quest for understanding what is a good VPN, remember that your start begins with mapping every layer of your network architecture. SSL VPN supports flexible remote access, while IPSec VPN is better suited for site-to-site connections.
Then again, ZTNA is revamping the way modern companies and IT teams are looking at business VPN solutions as a whole.

Frequently Asked Questions
What is a Good VPN for a Small Business?
A good small business VPN offers strong encryption, MFA, manageable access controls, and integration with your existing firewall solutions.
What is the Differentiator Between SSL VPN and IPSec VPN?
SSL VPN commonly supports browser-based access to business apps, while IPSec VPN operates at the network layer and is often used for site-to-site connections and broader network access.
Do I Need a VPN Firewall or is a Standalone VPN Enough?
A VPN can secure remote connections, but integrating it with a firewall adds traffic inspection and threat prevention.
What is ZTNA and How is it Different From a VPN?
Zero Trust Network Access (ZTNA) verifies users and devices before granting access to specific apps, rather than potentially providing broader network access like a traditional VPN.
How do I Manage Business VPN Licenses and Renewals?
Track license expiration dates, user counts, and renewal terms in a centralized system. Review usage regularly to maintain coverage, avoid service disruptions, and remove unnecessary licenses.
