SASE vs. VPN: What’s the Best Way to Secure Your Business Network?

Securing your team’s access to company resources while giving employees or contractors access is no longer as simple as configuring the firewall and calling it a day. 

Cybersnoopers and corporate spies may use advanced techniques to try and view your data, so it’s important to stay at least one step ahead. Deciding between a VPN and SASE is a key step in keeping your company’s network secure. 

If you’re not an IT expert, the jargon can feel overwhelming. So let’s break it down clearly. We’ll explain each option, when to use one over the other, and how to choose what’s best for your goals and budget.

What Is SASE?

SASE (Secure Access Service Edge) is a cloud-based framework that securely connects users, devices, and branch offices to applications and data without backhauling traffic through a central data center.

How Does SASE Work?

SASE uses a network of cloud-based service points (called Points of Presence, or PoPs) located around the world. When a user connects, the traffic goes to the nearest PoP. There, the system performs all the necessary security checks (like firewall, threat protection, and access control) and then sends the traffic to its destination, like a cloud app or a data center.

You can think of it as a global security checkpoint that follows your users around. Whether someone logs in from an office, a coffee shop, or overseas, SASE ensures their identity is verified, their device is safe, and they only get access to what they’re supposed to.

SASE Features

SASE isn’t just one tool; it’s a combination of networking and security tools that ensure users can securely and efficiently access applications and data from anywhere. Here’s what it uses:

• Zero Trust Network Access (ZTNA): Doesn’t trust anything by default. Every user and device must verify identity before accessing anything.
• Firewall as a Service (FWaaS): A cloud-based firewall that blocks malicious traffic before it reaches your systems.
• Secure Web Gateway (SWG): Filters harmful websites, phishing attempts, and malware in real time.
• Cloud Access Security Broker (CASB): Controls and monitors use of cloud services like Google Workspace or Dropbox.
• Software-Defined WAN (SD-WAN): Routes traffic over the best available path for faster, more reliable performance. Learn more in our comparison of SD-WAN vs. VPNs.

When Do You Need SASE?

As your business grows, it can put a strain on your network. SASE could potentially streamline processes and provide access to company apps and data for those who require it.

SASE is helpful when:

• Your team works from multiple locations or countries.
• You rely heavily on cloud apps (Google Workspace, Microsoft 365, Salesforce).
• You want centralized control over user access and security policies.
• You’re looking to reduce complexity by combining networking and security in one service.
• You need to enforce compliance and audit logs across all users and devices.

SASE Pros

✅ Built-in security: Features like a firewall, threat detection, and Zero Trust are unified into one platform.
✅ Cloud-native and scalable: Easily adds users, devices, or offices without needing new hardware.
✅ Local edge access for faster speeds: Improves performance for remote teams and global employees.
✅ Centralized management dashboard: Gives visibility and control across all users and traffic.
✅ Consistent policies across all devices: Enhances security even on personal laptops.

SASE Cons

❌ High cost per user: Bundled services mean more value, but also higher monthly pricing.
❌ Complex onboarding: Setup involves configuring identity providers, policies, and routing.
❌ Cloud dependence: Relies on internet connectivity and service provider uptime.
❌ Not ideal for legacy or offline systems: It may not work well with legacy apps, air-gapped systems, or networks that aren’t internet accessible.

What Is a VPN?

A VPN (virtual private network) creates an encrypted tunnel between a user’s device and a company’s internal network. All traffic gets funneled through a central VPN server, which routes it to its destination, whether that’s a file server, a cloud app, or a public website.

How Does a VPN Work?

A VPN encrypts the user’s traffic and routes it through the VPN server, masking their IP address and giving them secure access to company resources as if they were on-site. It’s a tried-and-true method for protecting data in transit, especially when employees are working remotely or connecting from unknown networks.

VPN Features

Enterprise VPNs typically include a few key features:

• Remote access VPN: Encrypts individual user connections to your internal network from any location.
• Site-to-site VPN: Creates a secure tunnel between two office networks, letting them function as one virtual environment.
• IPsec or SSL encryption: Secures traffic with strong cryptographic protocols that protect against interception or tampering.
• Split tunneling: Allows users to route only some traffic through the VPN, improving speed for non-sensitive tasks.
• Centralized authentication: Integrates with your identity system to manage access and credentials across all users.

When Do You Need a VPN?

A VPN is good software when your setup is relatively simple and you want a low-cost, fast way to secure connections. You’ll benefit most from a VPN if:

• Your business uses local servers or private cloud resources.
• You need to secure remote employee access to office infrastructure.
• You’re connecting a few branch locations via site-to-site VPN tunnels.
• You want to protect data in transit without overhauling your network.
• Your team works from hotels, airports, or public Wi-Fi.

VPN Pros

✅ Strong encryption for secure traffic: Protects sensitive business data from eavesdropping.
✅ Simple setup for remote access: Employees can connect from anywhere with minimal configuration.
✅ Affordable for small teams: Lower monthly costs and little to no hardware required.
✅ Compatible with most devices: VPN clients are available for nearly every platform.
✅ Can be self-hosted or third-party: Flexibility to choose full control or ease of use.

VPN Cons

❌ Trusts everything inside the network: A compromised device could move freely without additional controls.
❌ Limited visibility and logging: Difficult to track or audit user actions without extra tools.
❌ Slower performance: Traffic must go through the VPN server, which can slow things down.
❌ Manual scaling: Adding new users or locations often requires IT configuration.
❌ No built-in threat protection: You’ll need separate antivirus, firewalls, or monitoring tools.

SASE vs. VPN: What Do They Both Offer?

Before we dive into the differences between the two, let’s look at what they have in common:

Secure Remote Access

Both SASE and VPNs allow employees to connect safely to internal resources from anywhere, protecting sensitive data during transit.

Data Encryption

Each solution encrypts traffic to prevent interception. Enterprise VPNs use protocols like IPsec and TLS, while SASE builds encryption into its cloud-native architecture.

User Authentication

Both technologies verify user identity before granting access, making sure only authorized users can reach protected systems.

Support for Remote Work

SASE and VPNs enhance connectivity for remote and distributed teams by enabling secure access to applications, whether hosted on-premises or in the cloud.

SASE vs. VPN: Key Differences

Both SASE and VPNs secure connections, but they go about it in very different ways. SASE is cloud-first and security-rich. A VPN is direct and data-focused.

	VPN	SASE
Architecture	Point-to-point tunnel to company network	Distributed cloud network with security enforcement
Security model	Trusts internal network	Zero Trust (always verify access)
Built-in security	Limited to encryption	Includes firewalls, threat detection, and more
Performance	Slower with distance or congestion	Optimized cloud routing near users
Scalability	Manual configuration	Cloud-native and elastic
Management	On-premises or self-managed	Centralized cloud dashboard
Best for	Small teams, legacy apps	Remote teams, cloud-first orgs

SASE vs. VPN: Network Complexity and Management

A VPN works well when your team is small and stable. It’s relatively easy to set up and gives users secure access to internal resources. But as your organization grows, managing users, devices, and VPN servers becomes time-consuming, and it often leads to messy overlaps and limited visibility.

SASE replaces separate tools with one cloud-based platform where IT can manage access, security, and traffic from a single dashboard, without any hardware or manual updates required.

If your requirements are simple, a VPN can meet them. But if your business is scaling, merging locations, or supporting a bring-your-own-device (BYOD) environment, SASE significantly reduces the operational burden.

SASE vs. VPN: Compliance

VPNs encrypt traffic, which helps with compliance, but they stop there. They don’t log user activity, enforce detailed access rules, or offer much visibility into what happens after someone connects.

SASE tracks every connection, limits access based on identity and context, and keeps logs you can actually use in an audit. It can help you meet the technical safeguards required by standards like HIPAA, GDPR, or ISO 27001, without needing half a dozen extra tools.

If you just need to encrypt traffic, a VPN is fine. But if you need to prove access control and user accountability, SASE is the better fit.

SASE vs. VPN: Pricing 

VPNs are cheaper up front. You can self-host one for the cost of server space or use a third-party service for just a few dollars per user per month. They’re ideal when cost is the biggest barrier and your security needs are relatively basic.

SASE costs more because it does more. It combines secure access, traffic inspection, app control, threat detection, and policy enforcement into one platform. Some providers charge per user, others per site or based on bandwidth.

The real question is long-term cost. VPNs often need add-ons, like endpoint security, DLP, or monitoring tools, as your needs grow. SASE includes many of those out of the box, which can reduce complexity and IT overhead over time.

Is SASE or a VPN Better for Secure Remote Access?

If you need to connect a few employees to your internal network for access to local files or running desktop software, then a VPN is a simple and affordable solution. A VPN provides complete access to everything on the connected server, encrypts your data and traffic, and masks your IP address. 

However, if your team is spread out across multiple time zones, often switches devices or networks, and relies heavily on cloud tools like Slack, Zoom, or Google Drive, VPNs start to show their limits. Performance suffers because traffic is backhauled through a central server, and IT teams have less visibility into what’s happening across the board.

That’s where SASE comes in. It allows users to connect to the closest cloud edge, where advanced security and routing decisions are made in real time. It improves connection speed, user experience, and control to create a solution when remote access becomes the norm rather than the exception.

Has SASE Bypassed VPNs?

SASE solutions haven’t made enterprise VPNs obsolete, not by a long shot. However, they have changed when they make sense.

VPNs still offer a simple, effective way for trusted users to access internal systems, especially for small teams, individual remote workers, or companies with limited IT resources. They’re easier to deploy and manage, and they work well when most systems are still on-premises or don’t require granular access control.

SASE, on the other hand, fits best in cloud-first organizations with distributed teams and complex security needs. It doesn’t just encrypt traffic; it checks each connection in real time, applies identity-based policies, and defends against threats as they happen. 

This makes SASE a stronger fit for large, hybrid environments with lots of users, devices, and applications, but not necessarily the best choice for every business.

Can a VPN and SASE Work Together?

Yes, and there are plenty of companies that use VPNs and SASE together.

For example, your IT staff might still use a VPN to manage legacy servers that aren’t accessible via the cloud. Meanwhile, the marketing and sales teams could connect via SASE to access cloud apps with added threat protection, device posture checks, and usage controls.

Using both tools allows you to gradually upgrade your security model without disrupting what already works.
