The Role of FwaaS in Next-Generation Security

Fwaas _ Next-Generation Security

Organizations need a firewall to prevent attackers from reaching sensitive internal resources and internal networks, but traditional firewalls lack the adaptability and reach to protect the entire attack surface, which has expanded significantly due to remote access and cloud-based infrastructure.

By implementing FWaaS, which leverages automation and artificial intelligence to improve on traditional firewalls, as well as other tools, you can vastly decrease your likelihood of suffering a severe attack.

Quick Takeaways

  • Don’t forget about internal threats: Threats don’t always come from hostile actors. A major player in a security breach can be a well-meaning employee. Address this by implementing automated monitoring and establishing a zero-trust environment with strict access control.
  • Centralized control can help: The problem with combining multiple security tools is that they are often not integrated well, which can create security gaps. Consider implementing FWaaS as part of a SASE solution, which will provide a central hub for all of your tools. 
  • Compliance is key: FWaaS can better insulate you from compliance violations than a traditional firewall (or not having a firewall at all, which will almost certainly land you a fine). 

How FWaaS Adapts to Emerging Cybersecurity Trends 

Here’s how FWaaS adapts to the newest cybersecurity trends.

#1. Zero-Trust

88% of data breaches can be attributed to employee error.

So, implementing zero-trust policies and enforcing them with FWaaS can reduce the risk of an attack. FWaaS can help by providing monitoring and access control, so you will be able to see which employees access data and how they use it — you can also limit access to sensitive data. 

Attackers often target employees to gain access to your data because they can hide under an assumed identity to avoid detection. But with FWaaS in place, it becomes much easier to:

  • Control remote workers’ privileges
  • Detect unusual activity
  • Limit the amount of data an attacker can contact.

You can use FWaaS to restrict users, so a group that doesn’t need to access developer data, for example, cannot interact with the developers’ server. 

#2. Leveraging AI for Security 

The number of data breaches in 2023 increased by 72% over 2022 – and the same trend continues for 2024 as well…

As an increasing number of organizations shift to cloud-hosted infrastructure, security professionals are finding that traditional firewalls are insufficient to protect that infrastructure, especially given their increasingly limited resources.  

To make this easier, FWaaS solutions use AI and machine learning to better inform firewall rules.

Threats are popping up at a growing pace, and keeping up with them is nearly impossible. Using AI means that the firewall will adjust itself, and it will likely be able to make these adjustments with high accuracy and precision. 

#3. Enabling Automation

A disadvantage of traditional firewalls is their reliance on manual configurations and updates. This slows down your response to threats and reduces the efficacy of the firewall.

FWaaS includes automated monitoring and rule updates, which means you’ll be spending less time addressing security issues and more time investing in your organization. Automation also alerts you to unusual activity and can help with prioritization, which improves efficiency.

Timing Matters

Quick responses to cyber threats can make the difference between a successful attack and a thwarted one.  

#4. Compliance with Privacy Regulations

Failing to comply with data privacy regulations like the GDPR and CCPA can result in heavy fines, litigations, customer loss, and, in rare cases, imprisonment. FWaaS protects you from violations by improving your ability to block attackers and safeguard customers’ data. 

#5. Secure Access Service Edge (SASE)

FWaaS alone will benefit your business, but it is most effective when combined with other tools.

When you choose a FWaaS provider, find out whether SASE is available so that you can combine FWaaS with other cloud tools. SASE creates a centralized platform to maximize visibility into your environment.

This helps you and your security team manage all cloud tools and applications in one place to prevent data silos (and exploitable gaps that siloed applications create). 

The challenge of remote work is that it requires an employee to access your server from a place not protected by the office firewall. Rather than depending on credentials, which can be compromised, SASE monitors and evaluates user activity to confirm identity.

To mitigate potential vulnerabilities, FWaaS acts as the first line of defense around the cloud environment, and SASE is used to strengthen security by enforcing best practices during application use and by shielding your internal network. 

#6. Extended Detection and Response (XDR)

XDR focuses on endpoints and threat detection rather than on user identity and broad protection. A distinguishing feature of XDR is its narrative focus; when unusual activity occurs, XDR combines context with activity data to provide a cohesive understanding of the threat.

Identify Threats’ Behavior

This helps security teams identify the highest-risk threats and understand how they are interacting with your network and applications.

Implementing both XDR and SASE (including FWaaS) is vital to navigating today’s risky threat landscape.

What are the popular types of firewalls?
Popular types of firewalls include:

Next-generation firewalls (NGFWs): These advanced firewalls go beyond basic filtering and offer features like intrusion prevention and deep packet inspection for stronger security.
– Application firewalls (WAFs): These focus on securing specific applications by monitoring and controlling traffic at the application layer.
Cloud-based firewalls (or Firewall as a Service (FWaaS)): These are cloud-based services and security solutions that provide remote traffic filtering without needing physical hardware on-site.
– Hardware firewalls: These are traditional physical appliances that sit between your network and the internet, enforcing security policies by filtering traffic at the hardware level.
– Premise firewall is a hardware firewall that’s physically installed at your location. It acts as the first line of defense for your network by filtering incoming and outgoing traffic based on your predefined security policies.
What are the benefits of FwaaS?
FWaaS performs the functions of a firewall, but it also provides automated rules updates, access controls, and cloud-based software that monitors both on-premises and off-premises activity. 
What is the difference between FWaaS and SASE?
SASE is a platform that offers a centralized hub for monitoring and controlling all of your security tools. FWaaS is one of those tools or components. 
What is the difference between a firewall and a cloud firewall?
A firewall is typically a piece of software or hardware set up to protect on-premises devices connecting to your network. A cloud firewall, or FWaaS, is hosted by a provider and protects both on-premises and off-premises endpoints to facilitate secure remote work.
Do you need a firewall in the cloud?
Yes. FWaaS is a cloud-based firewall that protects your data and applications. Because cloud service providers do not typically protect your information for you, a firewall is essential for your ongoing security.
Is cloud firewall the future for enterprises?
As more enterprises migrate to the cloud, appropriate security measures are necessary. Because a traditional firewall can’t cover devices and other endpoints that aren’t in the office with it, a cloud firewall (FWaaS) is needed for tight security.
