A managed Firewall is an outsourced IT service which includes management, configuration, reporting and support of security policies, threat protection, web filtering with integration into SIEM (Security Information and Event Management).
Features include:
As companies move data and applications to the Cloud, the methods used to protect those assets have also had to evolve. Firewalls were initially designed in the 1990s to protect IT assets within the walls of an enterprise. However, as the Cloud changes the nature of the enterprise perimeter, firewalls have had to adapt to this new normal to cover the expanded and fuzzy enterprise perimeter. A cloud firewall uses an 'as-a-Service' (FWaaS) model of delivery to accommodate a cloud infrastructure's more complex security needs.
As cloud computing has become ubiquitous, cyber-threats have followed. Regardless of size or industry, the modern enterprise must defend its assets from these threats. This situation is complicated by the massive attack surface created by cloud computing and the edge devices used to access cloud-based data and applications. According to Check Point Research, cybercriminals take advantage of new cloud-based exploitations, with cyber-attack volumes against corporate networks increasing by 50% in 2021.
When an enterprise commits to using a cloud firewall, they must decide if they have the in-house skills to choose, deploy, configure, and manage the service in-house or use a Managed Service Provider (MSP) to handle the FWaaS solution.
The move to the Cloud has accelerated because of highly adaptive SD-WAN (Software Defined-Wide Area Network) solutions. For example, a cloud firewall can be bought as a service and easily integrated into an existing SD-WAN Edge (a physical or virtualised network function) or a virtualised environment.
The urgent need to protect cloud resources from sustained cyber-attacks has led to a massive increase in the market worth of cloud firewalls or Firewall-as-a-Service (FWaaS). Analysts value this buoyant market to be worth $8.28 billion by 2029, growing at a CAGR of 25.40% from a value of $0.3 billion in 2021.
The following details the different options which exist for IT teams considering managed services.
IT teams should consider the following components when comparing SD WAN services.
Advanced AI Firewalls use an AI engine to provide intelligent detection of threats. These firewalls use AI to deal with the ever-changing neater of modern cyber-threats. AI uses large datasets based on real-time data to train the underlying algorithm and keep it up to date with threats.
Managed firewalls offer enterprises more flexibility in managing their policies. FWaaS solutions can be configured and maintained from a central console; policies can be fine-tuned to meet regulatory expectations. In addition, a managed firewall makes extending protection to new devices and networks easier.
There is a delicate balancing act between security and agility. However, a managed Firewall is designed to provide agility whilst maintaining security. A managed FWaaS can quickly be configured to reflect any updates in your network, edge devices, and remote users. This allows your organization always to maintain a high level of security.
FWaaS uses a cloud delivery model. FWaaS can work on virtualised or physical appliances hosted in the Cloud and be part of a cloud-native architecture. An FWaaS solution is a fundamental component of a SASE framework, with an SD-WAN forming the underlying architecture.
FWaaS offerings have built-in alerting, monitoring, and reporting capabilities. As a customer of a managed FWaaS, the managed service provider will take responsibility for monitoring the output from the firewall and using alerts to provide triage and response to any identified threats.
Managed Firewall services use specialist penetration testing (PEN test) to ensure that they are optimally configured. These PEN tests show any security gaps and identify potential weaknesses. Once the test results are in, the organization managing the FWaaS will adjust the firewall settings to ensure any vulnerabilities are closed before deploying the Firewall.
By choosing an FWaaS from an MSP, your organization can access 24/7 managed services support. This is important as threats also work on a 24/7 basis and can put in-house IT teams under enormous pressure.
Local account management offers additional value to a managed Firewall service. The account management team will work closely with an enterprise on delivery, configuration and deployment.
An SLA is an agreement between the MSP delivering the FWaaS and the client organization. An FWaaS SLA typically includes the agreement and service description, service availability metrics, lines of contact when problems occur, monitoring and reporting, and various incident priority levels and how they are handled. There is also a clause for consequences for not meeting the requirements of the SLA.
Firewall as-a-service is a major component of SASE security deployment. Gartner classify SASE as including NGFW (Next Generation Firewall) to ensure all up to date modern features are included, i.e. Cloud derived policies.
One of the unique aspects of FWaaS is that it can handle remote global users. This is because a managed cloud-based firewall can be quickly and simply deployed to all network endpoints to enforce security policies.
Many FWaaS solutions offer out-of-the-box configuration settings to allow easy installation. These settings provide a baseline for an organization to quickly adjust settings to reflect their environment.
