FWaaS: Reducing Costs
A firewall delivered as-a-service, both managed and unmanaged versions, can be an ideal way for organizations to tackle the increasingly complex challenges surrounding distributed and Cloud VDS IT environments including servers, networking, cloud computing, and the unified security of the overall setup. It may allow users to stay in control when the security of the IT environment is concerned, but first let us elaborate on the cost of as-a-service firewalls versus the traditional approach of installing firewall technology. By the way, let’s continue to call it FWaaS in the rest of this article.
Firewalls are indispensable, but the traditional ones can be rackspace-consuming and cumbersome devices with high upfront expenses that additionally may cost quite some time thus money and particular knowledge to deploy and maintain. Firewalls delivered as-a-service, managed or unmanaged, don’t run into these constraints of physical equipment. Because the hardware does not need to be installed and maintained by its users or third-party service providers, overhead expenses are reduced as a result. At a fixed rate per month, users don’t have to worry about the significant upfront investments, the hardware configuration and maintenance, and the hardware knowledge that’s needed for traditional firewall deployment while they are assured that the network performs at its maximum and offers protection against possible attackers from inside and outside.
Many organizations have been obliged to implement new network operations methods as a result of the present reality of the COVID-19 worldwide pandemic. Changes in network traffic dynamics, a surge in encrypted network traffic, unsecured appliances, and quickly rising cyber threats increasingly require security and network architects to be ready to adapt. It calls for a swift enhancement of network traffic monitoring capabilities to keep the overview and maintain full network security visibility. It also asks for sophisticated firewall features to meet network performance and capacity requirements as well as suddenly changing conditions. Installing a hardware-based firewall wouldn’t allow for meeting these needs. It would be too expensive and time demanding. FWaaS provides a full-featured, flexible and cost-efficient alternative to the traditional approach for deploying firewall technology.
Central Management and Visibility
When installing traditional firewalls and managing the security of the IT infrastructure, over time, it may also result in much hassle with a mix of models and brands from multiple suppliers, despite of the fact that there are centralized administration consoles available in the market to manage these kinds of mixed environments. FWaaS is an important ingredient for setting up a unified and modern threat management architecture. It allows for the implementation of security standards and rules that are applied uniformly across the IT environment as a whole – regardless of the location or user.
An FWaaS solution enables users to implement security policies universally to all users and locations, as well as to all traffic, removing the need for separate network policies to be implemented. Any encrypted or unencrypted Internet traffic is accessible to a software-defined firewall, which helps eliminate blind spots while there’s no need for installing, monitoring, and managing numerous appliances.
In addition to centralized policy management, FWaaS offers an architecture that is simpler and more adaptable. At the same time, without the need for expensive hardware appliances, it equips users with centralized, increased visibility and full control over their networking environment thus contributing to an enhanced IT security architecture. With FWaaS, organizations are enabled to combine traffic from numerous sources into their IT environments while still obtaining total visibility and control over their networks.
FWaaS: Up-To-Date Security
Cybercriminals are continuously refining their assault tactics and tools in order to target organizations, steal company data and knowledge as well as intellectual property and technologies. When becoming a victim of cybercrime as a company, it may result in loss of profits, huge expenditures or at least a loss of reputation for the business. FWaaS delivers maximum flexibility towards securing distributed IT environments.
Preventive measures are required to keep an IT infrastructure safe from assaults. Yet many organizations are unable to maintain firewalls, install firewall updates, and modify access control lists and rules on their own since it may take a significant deal of time, knowledge, and experience while it occupies human and financial resources that may be better used elsewhere. A managed FWaaS solution allows for up-to-date security and convenience on the part of end users when deploying, maintaining, and managing firewalls, while for MSPs, MSSPs and systems integrators the unmanaged version may offer ample opportunities to offer FWaaS as a managed security service and integrate it into their managed services portfolios.
Unmanaged vs. Managed FWaaS
A firewall delivered as-a-service can be offered as a fully managed security solution or as an unmanaged one. The FWaaS solution offered by Zumiv, powered by Zumiv software-defined network and built on top of its global 10Tbit/s backbone, is a great example of an unmanaged FWaaS offering. It is aimed at managed service providers (MSPs), managed security service providers (MSSPs), systems integrators, independent software vendors (ISVs), and other tech-savvy companies that are basically looking for the very highest flexibility, scalability, and agility for their firewall deployments. For those integrating unmanaged FWaaS in a unique security offering, for example a Secure Access Service Edge (SASE) architecture, profitability of the firewall in the integrated solution may also be an argument for choosing unmanaged FWaaS.
Then again, with unmanaged FWaaS, you must exactly know what you’re doing. For those organizations that don’t have the skills and knowledge to configure and maintain an unmanaged FWaaS solution, a managed alternative will most likely be a better fit. Even when considering that FWaaS offers central management, ease-of-use, and faster deployment times compared to the use of more complex firewall hardware appliances, it still requires skills, knowledge, time, and staff to take over the continuous management of FWaaS. If you don’t have the internal resources available to deploy and sustain an unmanaged firewall solution within a virtualized network architecture, you might be better off opting for a third party managed FWaaS solution.
An unmanaged FWaaS solution like the one delivered by Zumiv allows MSPs, MSSPs and other security experts to granularly meet the fast-changing security requirements set by trends like multi-cloud, IoT, edge computing, 5G, work-from-home, increased video consumption, and encryption. When it comes to firewall settings, the virtualized aspect offers security experts the opportunity to address flexibility and agility needs in a cost-effective and versatile way and adapt quickly to changing network traffic dynamics. The unmanaged attribute provides a vast array of options to achieve a fine-grained level of control and dynamically address fluctuating network traffic while creating the ability to change any firewall setting the same day. Unmanaged FWaaS allows for fine-grained configuration, for example when it comes to securing the architecture and management of micro-segmented or highly distributed networks, getting extensive visibility into internal east-west network traffic, meeting unique compliance requirements, or finding an optimal balance between security and network performance.
