Hardware Firewall vs Synology Firewall: What’s Better?

Why It’s Important to Choose the Right Firewall

Any network that stores, processes, or backs up business data needs a firewall as an important part of its cybersecurity. For companies that use Synology NAS systems, the firewall strategy has an effect on:

Network security posture
Integrity of backup
Controls for access
Getting connected from afar
Preventing threats

Hardware firewalls and software firewalls, like the one that comes with Synology’s DiskStation Manager (DSM), are two common ways to protect your computer. IT leaders can pick the best protection for their environments if they know the differences.

What Does a Synology Firewall Do?

The firewall that comes with Synology is a software firewall that is part of DSM. It controls traffic coming in and going out of the NAS based on rules set by administrators. Learn firewall essentials for Synology NAS security and protection.

It gives:

Filtering based on ports and services
Matching IP and subnet rules
Filtering by location
Rules for allowing and denying in layers

This firewall is great for keeping NAS services like file sharing, remote access, backup agents, and administrative interfaces safe from unauthorized access.

What is a firewall for hardware?

A hardware firewall is a separate piece of hardware that is put at the edge of a network to protect all of its connected systems. It checks traffic at the edge and enforces security rules across many devices and services. Explore the best hardware firewalls for NAS and networks.

Some common features of hardware firewalls are:

Packet inspection with stateful information
Dividing up the network
Ending a VPN
Detection and prevention of intrusions
Managing rules from one place
Setting priorities and shaping traffic

Hardware firewalls don’t depend on any one server or NAS.

When the Synology Firewall Is Enough

When the Synology Firewall is enough:

Only trusted internal networks can access NAS services.
The network topology of the organization is simple.
VPNs or secure tunnels are used for remote access.
Backup servers and endpoints are on a LAN that is controlled.

The Synology firewall protects certain services and ports without affecting the rest of the network because it works at the NAS level. It gives a strong base layer for small offices or controlled environments. View Synology SRM firewall rule updates and behavior.

When a hardware firewall is better

When you need a hardware firewall, it’s better to use one when:

There are many important systems in the environment
Segmentation of the network is necessary
To work from home, you need a secure VPN termination
Advanced threats and attempts to break in happen all the time
Compliance with regulations requires security for each zone

Hardware firewalls protect more by having features like intrusion detection, deep packet inspection, and centralized rule sets that work for more than one device.

A hybrid approach means using both

In a lot of business settings, the best way to use both firewalls is to:

Firewall hardware at the edge of the network
The NAS itself has a Synology firewall

The perimeter device keeps out big threats and controls zones. The NAS firewall is the last line of defense for storage services and remote access.

This layered security method makes sure that:

Less area for attacks
Access control by segments
More security for backup workflows
Easier reporting for audits and compliance
Effect on Backup and Access from Afar

Firewalls have an effect on how reliable backups are. For instance:

Backup agents might not be able to connect if there aren’t clear rules.
If network defenses aren’t strong, ransomware can spread sideways.
Without secure VPN or firewall settings, remote backup targets may not be reachable.

Combining firewall rules with backup plans makes sure that important data flows stay safe and don’t get interrupted.

Best Ways to Set Up Firewalls

You can use hardware, Synology software, or both:

Set up clear allow lists for services you trust
Use rules that deny everything when you can
Put backup and NAS traffic on different VLANs
Check logs and alerts on a regular basis
Quickly update signatures and firmware

For long-term security that you can count on, you need to keep up with regular maintenance. See a beginner’s guide to Synology firewall rules and usage.

Things to think about when planning for IT teams

The choice of firewall should be in line with:

Risk profile of the organization
Requirements for compliance
Money and resources are available
How complicated the network is

A mature security strategy usually has more than one layer of protection. For example, firewalls work with endpoint protection, monitoring, and secure remote access.
