In a digitally connected world, cybersecurity has become a top priority. A managed firewall takes on the task of safeguarding your network, stopping threats before they reach your critical systems. This level of protection goes beyond traditional firewalls by bringing in a team of experts to handle complex security needs, making managed firewalls a game-changer for modern businesses.

With a managed firewall in place, you don’t just get a static defense wall. Instead, you get continuous monitoring, real-time threat updates, and a proactive approach to managing security challenges. So, how does a managed firewall differ from other types? Let’s explore its core functions and benefits to see why it’s a must-have in your security strategy.

What is a managed firewall?

A managed firewall is a network security service that’s handled by a third-party provider. Unlike a traditional firewall, which you need to monitor and configure yourself, a managed firewall is monitored by experts who actively oversee your network for any signs of suspicious activity. This service includes updating firewall policies, implementing new threat protections, and reacting instantly to emerging risks.

With a managed firewall, you gain a higher level of security without the burden of constant management. It’s especially valuable for organizations without a dedicated IT security team, as the managed firewall service takes care of complex configurations, regular updates, and real-time threat monitoring, ensuring a high level of protection around the clock.

When do you need a managed firewall?

A managed firewall becomes essential when your organization’s network grows beyond a certain size or complexity. As businesses expand, their data becomes more attractive to cybercriminals, making a stronger, actively managed firewall necessary to ward off threats. If you’re facing increasingly complex security challenges or lack the resources to handle these issues internally, a managed firewall service can fill that gap.

Another sign you may need a managed firewall is when your in-house team is stretched too thin. Managed firewalls take the workload off your IT staff, allowing them to focus on other critical tasks while knowing that your network is secure.

Key features of a managed firewall 

Managed firewalls come with a range of features tailored to address evolving security needs. Here are some of the most impactful features that set them apart:

1. Real-time monitoring and alerts

A managed firewall keeps a constant eye on your network traffic. With real-time monitoring, any unusual activity triggers immediate alerts, allowing swift responses to potential threats. This feature acts as a critical line of defense, detecting attacks before they cause harm.

2. Regular updates and Patch Management

Cyber threats evolve, so managed firewalls include consistent updates and patching to stay ahead of vulnerabilities. These updates are automatically implemented by the provider, ensuring your firewall is equipped to handle the latest threats without requiring manual oversight. Without a managed firewall, you team would need to implement its own Patch Management process.

3. Advanced threat detection

Managed firewalls integrate advanced threat detection technologies, including AI-based anomaly detection and behavior analysis. These technologies help identify sophisticated attacks, such as zero-day vulnerabilities, which might otherwise slip past traditional firewalls.

4. 24/7 expert support

One of the most valuable features of a managed firewall is access to a team of security experts available around the clock. These professionals monitor your network, manage incident responses, and provide valuable insights to keep your system secure.

Benefits of a managed firewall

By choosing a managed firewall, organizations gain several unique advantages that boost both security and operational efficiency. Here’s how:

1. Enhanced security posture

With dedicated teams monitoring your network, managed firewalls provide a significant boost to your organization’s security posture. They proactively manage threats, keeping your systems protected from both known and emerging attacks.

2. Cost-effective protection

Outsourcing your Firewall Management can save on costs associated with hiring and training an internal security team. Managed firewalls deliver top-notch security at a fraction of the cost, making it an attractive choice for organizations of all sizes.

3. Reduced IT workload

With the complexities of Firewall Management taken care of, your IT team can focus on other priorities. Managed firewalls offload the burden of constant updates, policy adjustments, and monitoring, giving your IT department valuable time back.

4. Scalability

Managed firewalls can easily adapt to your organization’s growth. Whether your network scales up or down, the firewall service adjusts accordingly, ensuring continuous protection without needing a complete overhaul.

Common security threats addressed by managed firewalls

Managed firewalls act as a defense against a variety of cyber threats, providing a proactive approach to protect your network. Here are some of the most common security threats managed firewalls help to prevent:

1. Distributed Denial of Service (DDoS) attacks

DDoS attacks can overwhelm your network by flooding it with malicious traffic, slowing down or even crashing critical systems. Managed firewalls detect and block these attacks before they disrupt operations, ensuring continuous availability.

2. Malware and ransomware

With the rise of sophisticated malware, including ransomware that encrypts data, managed firewalls offer an essential layer of protection. They block suspicious traffic, preventing malicious software from infecting your network and compromising sensitive data.

3. Phishing and social engineering

Phishing attacks attempt to trick employees into providing sensitive information. Managed firewalls help by blocking access to phishing sites, mitigating the risk of data breaches stemming from social engineering attempts.

4. Unauthorized access and data exfiltration

Managed firewalls monitor network traffic for signs of unauthorized access and detect attempts to transfer sensitive data outside the network. This stops data exfiltration, ensuring confidential information remains secure.

What is the difference between managed and unmanaged firewall?

The primary distinction lies in who manages the firewall. With a managed firewall, a service provider handles all aspects, from monitoring to incident response. This service includes a team of experts actively working to keep your network secure, offering real-time responses to threats and ensuring the firewall is always up-to-date.

An unmanaged firewall, on the other hand, requires an internal team to handle configurations, updates, and monitoring. While unmanaged firewalls offer more control, they demand significant time and expertise from in-house staff, which can strain resources, especially in smaller organizations.

Best practices for managing a firewall

Effective Firewall Management involves more than just installation. Adopting best practices ensures your firewall delivers optimal protection. Here are some essentials:

1. Regularly update firewall rules and policies

Outdated firewall rules can leave your network vulnerable to attacks. Regularly updating and reviewing firewall policies prevents old, unnecessary rules from creating security gaps. By aligning policies with your current security needs, you maintain a stronger defense against threats.

2. Conduct frequent firewall audits

Frequent firewall audits allow you to identify any misconfigurations or outdated policies. These audits assess your firewall’s effectiveness, highlighting areas that need improvement. By conducting regular audits, you ensure your firewall stays aligned with the latest security standards.

3. Monitor network traffic patterns

Understanding normal traffic patterns makes it easier to detect anomalies. By closely monitoring network traffic, you can quickly spot unusual activity, enabling a faster response to potential threats.

What does a firewall manager do?

A firewall manager oversees the firewall’s configuration, monitoring, and updating. This role involves adjusting firewall rules to align with changing security requirements, ensuring policies reflect the latest threat landscape, and responding to any security incidents.

Beyond these responsibilities, a firewall manager also works on optimizing firewall performance, making sure the network runs efficiently while staying secure. This position is crucial in larger organizations, where managing complex firewall setups requires dedicated expertise.

How to choose the right managed firewall provider

Choosing a managed firewall provider is crucial for the security of your network. Here are some essential criteria to consider when evaluating providers:

  • Service reliability and uptime: Look for a provider with a strong track record of reliability and guaranteed uptime. Downtime in firewall services can leave your network vulnerable, so it’s important to choose a provider with a dependable infrastructure.

  • Customization options: Every organization’s security needs are unique. Ensure the provider offers customizable policies, reporting, and alerts to match your specific requirements. The flexibility to adjust rules and monitoring criteria will allow for a more tailored security approach.

  • Support and expertise: Around-the-clock support is a must. Look for providers that offer 24/7 support from security experts, ensuring assistance whenever you need it. It’s also beneficial if the team can proactively advise on best practices and respond quickly in emergencies.
