At this point, you’ve probably coped with selecting a firewall that suits your current business requirements. Great! But the next steps imply error-free installation, setup, and implementation according to all the compliance requirements. If you do everything right, you’ll be able to:


Although installing a firewall may seem like a no-brainer, its setup supposes more than just ticking off a few checkboxes. Firewalls need to be properly configured if you plan on using their functionality to the fullest. In fact, configuring a firewall can be a rather complicated and time-consuming task, depending on the specific company's needs.

At this step, it is essential to:

  1. Apply the setup and configuration best practices
  2. Triple-check the firewall configuration

OutsourceIT.PRO’s team of firewall experts and security professionals does its best to avoid misconfigurations at all costs, as we’re well aware of the potential threats a company might face if something is set up incorrectly. Here are a few things you should know about:


What does OutsourceIT.PRO encourage you to conclude from the above?

⚠️ Your firewall configuration has to be tested regularly ⚠️

Otherwise, the firewall will fail to live up to expectations and may harm the business.

Need an example? Say, you have a cluster of two firewalls set up in different locations. You expect that if one of them goes down, the other will take over, handling all the traffic and ensuring your service continues to operate. If it doesn’t, such firewall misconfigurations can cost your business lots of money due to downtime.

The scope of work that OutsourceIT.PRO’s firewall setup service includes varies from case to case. But to give a general overview, the following is often configured during firewall setup:

Network segmentation, zero trust security model implementationFirewall rules, access control list ACL with application and user identification adoption
Site-to-site VPN with third-party partners or customersRemote access VPN (for remote staff and employees)
Monitoring and security alerting (in case of threats or malfunctions)Third-party system integrations (SIEM, DLP, and others)
High availability (reserving communication channels and devices and automatic circuit switching between them)Security profiles for ACLs (vulnerability protection, anti-spyware protection, antivirus protection, DoS protection, user identification, role-based access, etc.)


As mentioned before, the resource-intensiveness and scope of firewall configuration processes can differ. Here are a few rough estimates of the average duration:

🕗 - The simplest firewall installation could take as little as 8 business hours (for example, the most basic functionality configuration, including making an addressing scheme and granting Internet access to office employees without the implementation of policies).

🕛 - Installation and setup from scratch may take up to 24 business hours (this includes creating firewall rules and policies).

⏱️ - Custom cases can take a week or more (this may be the scenario of firewall migration, for example).


There is no one-size-fits-all solution here, as each company’s case is unique. Yet, OutsourceIT.PRO approaches any firewall configurations solely based on best practices.


We won’t start firewall configuration without getting an in-depth understanding of your business needs. We won’t disrupt your processes.

We’ll first find out whether you have existing firewall policies and network security rules that have to be implemented to the controls, URL filtration functions, threat protection, and other areas.


If you don’t have established security standards and firewall configuration requirements, we can help you create them.

Likewise, you can count on us to implement them, handle the configuration, and assist with its operation. We could also help with firewall management and maintenance, hold regular audits, make upgrades, and IT hygiene clean-ups.

OutsourceIT.PRO offers several firewall setup service packages to choose from based on your needs:


1Why is firewall configuration important?
Thoroughly configuring a firewall according to the best practices is vital for businesses as it directly affects network security. Misconfigurations pave the way to breaches such as unauthorized access, making the system more vulnerable to cyberattacks. Therefore, it is crucial to ensure the firewall is configured securely and meets the unique business requirements.
2What are some best practices for firewall configuration?
One of the main rules in this regard is reviewing and updating your firewall rules regularly. This will allow you to ensure that nothing conflicts, or isn’t outdated or illogical.
3How do I know that my firewall configuration settings are okay?
You can find out whether your configuration is all right by conducting an audit of the firewalls you use. If you lack the needed knowledge, you may turn to firewall professionals like OutsourceIT.PRO who can run a detailed check-up, report on what needs improvement, and even implement the necessary changes.
4Can I configure my firewall myself, or do I need professional assistance?
If you have the required skills or a dedicated specialist in-house who can take on this responsibility, then this is possible. However, if you lack the expertise and you leave the firewalls without regular check-ups and maintenance, this could lead to drastic business consequences. A way out is opting for firewall configuration services. This way, you’ll delegate the matter to professionals who can keep an eye on the systems, ensure that the firewall configurations are aligned with industry best practices, and proactively solve issues if they arise.

Usually, reputable firewall setup service providers also monitor the firewall configuration, optimize it, and update it over time.
