Why You Need the Right Types of Network Security
Your business network is more than just computers and servers. It runs your daily operations, supports your team, and stores important information. Every new device, app, or remote login increases risk.
Cybercrime is set to cost businesses up to $10.5 trillion by 2025. That staggering figure reflects how quickly attackers are exploiting weak points in business networks, from outdated firewalls to unsecured data and poorly protected remote access.
Daren Boozer, CEO of NCC Data, noted that “Too many businesses are still using old security tools that don’t offer enough protection. Understanding what types of network security exist helps close those gaps.”
This blog breaks down the different types of network security. You’ll learn what each one does and how it helps protect your business, reduce downtime, and support compliance.

Why Network Security Needs Layers
No single tool can stop every threat. Malware, phishing attacks, open ports, and unsecured devices each introduce unique risks, and each requires a different kind of defense.
That’s why a layered security approach is essential. By combining multiple tools, each designed to target specific vulnerabilities, you can build a more resilient network.
Think AI-powered threat detection, 24/7 monitoring, and support that complements your internal IT team. The result? Full coverage without the need to expand your staff.
80% of businesses have experienced an increase in cyber threats since shifting to remote work. With cloud applications and remote work now standard, attackers have more entry points than ever. Your security strategy needs to extend across office networks, cloud platforms, and remote devices alike.
A co-managed support model can help you identify weak spots, resolve issues quickly, and strengthen protection across all systems.
Core Types of Network Security Every Business Should Use
These tools form the base of your network protection. Each one has a clear job. Together, they reduce the risk of downtime, theft, and non-compliance.
1. Firewalls and Next-Gen Firewalls
Firewalls act as filters between your network and the Internet. They check incoming and outgoing traffic and block suspicious activities. Next-generation firewalls (NGFWs) go further. They examine data more deeply and block both known and new threats.
Modern firewalls protect devices across multiple locations—your office, cloud platforms, and remote sites. You can manage all settings from one place.
2. Intrusion Prevention Systems (IPS)
IPS tools scan traffic for signs of an attack and stop it before it causes damage. They act automatically and don’t just send warnings.
Many IPS tools offer “virtual patching.” This means they can block known weaknesses even before a vendor releases an official fix. They also monitor traffic moving within your network, not just what enters from outside.
3. Antivirus and Sandboxing
Antivirus software blocks malware by recognizing known threats. Sandboxing adds a layer of protection by isolating unknown files and testing them in a safe environment.
If an employee downloads a file, the antivirus checks it first. If it’s suspicious, the sandbox runs it in a safe space to see if it behaves like malware. This helps stop new or hidden threats.
4. Network Access Control (NAC)
NAC tools check every device before it connects to your network. If a device doesn’t meet your security rules, NAC can block it or limit its access.
This prevents unsafe or unknown devices from causing problems and helps meet compliance standards.
5. Web and DNS Filtering
Web filters block access to dangerous or inappropriate websites. DNS filters stop connections to harmful domains before the site even loads.
These tools also allow you to set rules for what websites your employees can visit while on your network.
