What is a Managed Firewall & Does Your Business Need One?

Let’s try to understand the basic difference between a managed firewall and a traditional firewall before getting started.

You probably know what a firewall does, right? It keeps the bad guys away from your network or computer system by blocking unauthorised access.

But, if you look beyond that, a firewall can also be used as a monitoring tool!

You can even gather valuable data, such as what type of threat is more likely to show up shortly or what type of people are likely to harm your network.

Of course, monitoring a network is not a job for a naive employee but requires expertise, time, and resources.

Here’s where a managed firewall service, offered by security experts, comes in.

What Exactly is a Managed Firewall?

A managed firewall is a service offered by qualified Managed Security Service Providers (MSSPs) to tackle security threats or monitor your business network. The service also includes maintenance, operation, and administration of your firewall infrastructure.

Firstly, depending on the offering or service agreement, an assessment of security threats or monitoring of network traffic is carried out. After the MSSP team identifies what “normal” traffic looks like, they can easily detect unusual traffic patterns and take appropriate action to correct them.

What else do you get from MSSP?

• Modification of firewall rules
  
• In-depth analysis
  
• Feedback and reports
  
• Updates and patching
  
• Network monitoring
• Set-up

Does your business need a Managed Firewall?

To protect sensitive data, firewalls can be a saviour for your network traffic. Additionally, they are needed for compliance with mandates such as GDPR, HIPAA, and PCI DSS.

If your organisation lacks the personnel resources to manage security devices or firewalls to fill data security gaps or prevent data breaches, you can go for a managed firewall service.

Although you can employ your internal IT personnel to manage firewalls, it is a safer and easier choice to rely on a managed firewall service for better results. Let’s not forget, doing so helps you focus on crucial business objectives.

If you’re thinking of firewalls as plug-and-play devices, you are mistaken.

Just set it up, install it on the network, and the job is done with no human intervention — that’s not how firewalls work, sorry.

They demand constant monitoring and a high level of expertise. Setting up a firewall or purchasing one is just the first step; a lot needs to be done to achieve proper firewall management.

But, it’s not always a smooth ride with firewall management, as it can have issues or complexities. Remember, these issues are not a sign of trouble if they are checked on time by MSSPs.

Below are some of the most common firewall management failures faced by security analysts. Hope it will be helpful for your business to stay prepared for such situations.

• Several Firewalls, Many Locations

Even a single firewall demands regular monitoring and maintenance, which includes patching firmware, configuration updates, or reviewing rule sets. Now, imagine the overload of work due to multiple firewalls. In such cases, managed firewall services can be difficult due to a lack of necessary skills, loss of crucial data, and security issues being overlooked.

• Lack of Auditing

Many organisations often miss this vital step, but analysing firewall rules should be a priority. You can leverage managed firewall services to perform daily firewall audits.

• Striking a Balance Between Security and User-Friendliness

If users’ access needs for certain apps or data are not met, or if protocols are too restrictive, firewalls might end up being business inhibitors. On the other hand, giving out excessive access to finish job responsibilities can lead to data exfiltration or security breaches.

• Lack of Necessary Expertise Among IT Personnel

IT personnel are often under constant pressure to keep the system running for regular operations. Just like everyone, they might end up making mistakes due to risky configurations or carelessness. When an issue arises, IT employees might apply any rule without much thought to find the root cause. At the end of the day, it’s the network that suffers at a heavy price.

• Failure to Keep Up with Upcoming Threats

Firewall management rules or configurations that worked in the past months or even weeks may no longer be effective against new cyber threats. As the attack surface of your organisation increases and the threat landscape widens, it becomes a herculean task to maintain good firewall management. Make sure your business is future-ready to tackle threats by availing of managed firewall services.

• Non-Compliance of the Firewall with PCI DSS

Let’s say your organisation seeks assistance from MSSPs for managed firewall services, but the MSSP may not comply with PCI DSS. In this case, your organisation will be listed as non-compliant.

To be on the safe side, ensure that your service provider offering managed firewall services is PCI compliant and provides you with a current Attestation of Compliance (AOC) if required.

• Never Bypass the Firewall Security Gaps

Experts in the field have noticed that security gaps or firewall misconfigurations cannot be overlooked under any circumstances.

Did you know that data breaches at big retailers or restaurants often occur due to firewall misconfigurations? Thus, organisations need to understand their firewalls inside and out. Initially, they can manage, maintain, or implement devices practically, but after a certain point, they should consult a genuine and experienced service provider for exceptional firewall management.

It’s well known that a third perspective can be invaluable in identifying critical issues that might go unnoticed by your internal team.

Frequently Asked Questions

1. What’s the difference between a managed firewall and a standard firewall?

A standard firewall provides basic network security by filtering and controlling traffic entering and leaving your systems. A managed firewall service goes further by including ongoing monitoring, configuration management, security updates, threat response, performance tuning, and reporting delivered by a dedicated IT security team. This helps reduce the internal workload while improving overall protection.

2. Can managed firewall services support compliance requirements?

Yes. Managed firewall services can help businesses meet compliance requirements by improving access control, monitoring network activity, and maintaining security reporting and audit records. While firewall management supports many security standards, businesses still need internal processes and policies in place for broader compliance responsibilities.

3. How do we choose the right firewall solution for our business?

The right firewall solution depends on your business size, network complexity, workforce setup, and internal IT capabilities. Businesses with multiple locations, remote employees, or limited in-house security resources often benefit from managed firewall services, which provide stronger oversight, consistent policy management, and proactive threat monitoring.

4. Are managed firewall services expensive?

Not always. Managed firewall services are often more cost-effective than dealing with unexpected security incidents, downtime, or emergency recovery projects. They provide predictable support costs while helping reduce operational risks and improving long-term network security.
