What is Firewall Protection?

Network firewalls have been in operation since the late ’80s. It is their task to protect the corporate network from the Internet.

The Internet is a beehive of cybersecurity threats such as malware, phishing, viruses, and ransomware. Thanks to an army of cyber criminals, modern businesses need to continually advance their cybersecurity posture to stay protected.

The Network Firewall

Connecting the network with the Internet isn’t as easy as it looks.

  • Reduce complexity and operational overhead
  • Deliver ease of use/transparency for users
  • Enhance security with zero-trust network access

Next Generation and Cloud-Based Firewalls
Muddy the Water

By definition, SWGs (Secure Web Gateways) and NGFWs (NextGen Firewalls) have a very similar purpose.  They prevent suspicious traffic from entering or leaving the network. DNS (URL filtering), DLP (Data Leakage/Loss Prevention), application-level awareness, and detection of malware are some of the key features promoted by secure web gateway providers.  At the same time, network firewall providers make similar claims.

Not all secure web gateways and network firewalls can perform all those services, nor should they.  This is a heavy burden for a single system, especially if the organization has a high volume of internet traffic.  Performance may be improved and latency reduced by spreading security services across multiple devices – network firewalls and secure web gateways.  The network firewall may be performing DPI (Deep Packet Inspection) and SSL scanning while the gateway is delivering DLP (Data Loss Protection) and URL filtering.

The challenge is that an architecture with two or three separate processes, each with its own inspection, discovery, and action is likely to be more accurate but may induce latency if the processes are serial in nature.

Deliver Your Cybersecurity Posture with MDR

The best approach might be a cloud-native service that doesn’t confine features to ‘this is an FW-as-a-Service’ or ‘this is a cloud-native secure web gateway.’  Rather it takes a more holistic view of the customer and applies services as part of an entire cybersecurity platform.  These suppliers are known as MDR (Managed Detection and Response) providers.

Many organizations are turning to an MDR service to deliver their cybersecurity posture. A complete MDR service encompasses nearly all the processes, technologies, and techniques used to detect, deter, and remediate cybersecurity threats and attacks.  This includes remote users, cloud applications, compute clouds, WANs, and remote sites.

  • Advanced MDR service providers not only instruct the user on how to contain and remediate cyber-attacks but, if allowed behind the network firewall, will help bring attacks to ground.
  • Leading MDR providers can also replace or augment the traditional SOC (Security Operation Center) with SOC-as-a-Service.  The customer can be involved in cybersecurity management to whatever level they desire, minimal to very hands-on.

Cloud-Native Protection for the Network

A next-generation network firewall and secure web gateway may be able to provide the cybersecurity posture you require. For performance-sensitive and distributed networks, a more comprehensive and holistic cybersecurity stack, such as MDR, may be more suitable.
