Firewalls are essential to network security, even with a Cloud solution like Infrastructure as a Service, but traditional firewalls won’t cut it when it comes to today’s rising security demands. Next-Generation Firewall (NGFW) is the key to ensuring security in response to an increase in advanced security threats.
In this blog, we share three reasons why upgrading to NGFW is a modern security necessity and how its features will make a difference in keeping your business secure.
Why NGFW is a Modern Security Necessity
1. Cybercrime is rising, and increased application use has opened up new vulnerabilities.
Research shows that cybercrime is rising while the technology and tactics used by cybercriminals are becoming more sophisticated. For instance, The SSL Store reports:
- Enterprise ransomware attacks increased by 12% in 2018
- 1 in 50 emails contain some form of malicious content
- Mobile ransomware jumped 33% last year
- An estimated 10% of all malicious emails contain malware such as ransomware, spyware, adware, or trojans
Adding to these concerning statistics is that application usage has skyrocketed in recent years, bringing increased vulnerabilities with them. Considering that applications like Trello, Slack, and Skype have become popular for, or even integral to, business productivity, their use isn’t likely to go down. The solution? Application vulnerabilities need to be checked, which is where NGFW comes into play.
While traditional firewalls only block forbidden packets by protocol or port, NGFW takes security even further by inspecting packets all the way down to the application layer. This provides protection for attacks on layers 4-7 of the OSI (Open Systems Interconnection), where the growing number of application attacks are taking place.
To defend and safeguard against the emerging and unknown threats in today’s security landscape, NGFW’s advanced malware capabilities are needed. These capabilities include Packet Filtering Network Address Translation (NAT), URL Blocking, VPN, Quality of Service (QoS), Intrusion Prevention SSL, Deep-Packet Inspection, and more.

2. Traditional firewalls are complex and time-consuming, crippling response time.
Simplicity and automation are key to reducing your workload and saving money, but if you’re still using traditional firewalls, you’re likely dealing with unnecessary complexity and wasted time. This is especially true if your security provider is constantly adding new devices to your firewall, which means that more overhead is required, and even worse, it could mean your response time to threats will be slowed.
Traditionally having to be used through separate devices, NGFW integrates enterprise firewall capabilities, intrusion prevention system (IPS), and stateful packet inspection into one device. This allows for improved performance and accessibility.
Through automation and integration, NGFW reduces the number of manual tasks necessary, improving remediation speed. Security policies, service orchestration, monitoring, and reporting can all be centrally managed thanks to NGFW, saving your business time and money.

3. Moving to the Cloud doesn’t protect your existing network infrastructure.
Cloud solutions like Infrastructure as a Service (IaaS) offer increased security when compared to on-premises solutions, but that doesn’t mean you can neglect firewalls. Even if you move all of your infrastructure to the Cloud, your business still has devices such as employee computers and a network connection that will remain vulnerable without a firewall. What if an unwitting employee accidentally clicked on a malicious link and your network wasn’t protected by a firewall? That’s a costly problem that could have been prevented.
Knowing that firewalls are still necessary for Cloud services, why should you choose NGFW over a traditional firewall? NGFW offers protection that functions in this new age of remote workers and BYOD policies. While traditional firewalls restrict your protection to a single location, NGFW protects your network no matter where your employees are working or what device they are using.
Additionally, NGFW removes the blind spots of traditional firewalls, offering:
Application-level control for superior visibility, allowing you to see and control what applications are being used on your network
Identity awareness that integrates with application awareness to enable you to apply security policies more granularly using corporate directories
NGFW gives you increased knowledge and nuanced control over how your employees access and use websites and applications.

Are You Ready for Next-Generation Firewall?
NGFW provides essential capabilities against rising cybercrime and new application threats while simplifying your workload through integration and automation. Whether you’re already using Infrastructure as a Service or are looking into other Cloud options, don’t let the lack of adequate protection open your doors to unnecessary vulnerabilities.
Keep in mind that if you decide on NGFW, it’s crucial to choose an experienced provider that you can trust to be there for you beyond implementation. With more power, features, and functions, the set-up and ongoing management of NGFW are more important than ever.
