The Need for an Integrated Cloud and On-Prem Security Strategy for Hybrid Networks

The Need for an Integrated Cloud and On-Prem Security Strategy for Hybrid Networks

The new reality that today’s IT teams must learn to live with, is a continually evolving network. Instead of everyone migrating to the cloud, the industry is witnessing a near-universal adoption of hybrid network architecture. New edges are added to the network due to user demand, digital acceleration, and evolving business strategy, making it more complex to manage and more challenging to secure.

One of the biggest challenges that companies confront is providing consistent policy enforcement and broad visibility across a network where applications, devices, users, edge platforms, and different compute and networking platforms – many of which are temporary – are continuously changing. 

According to IBM’s Cyber Resilient Organization Study 2021, enterprises have deployed an average of 50 cybersecurity tools in their networks. Most of these are isolated point solutions that prevent IT teams from centralizing configurations and management, orchestrating policies, or even controlling their security architecture. 

Modern On-Premises Security 

For today’s networks, performance is identified as a top necessity. Connections are the lifeblood of networks, and the faster they are, the better. High network performance is also required by organizations to improve user experience, optimize applications, and promote digital agility.

As a result, security tools require more processing power than network devices. A network security appliance must be significantly faster than a networking device to accomplish its function without affecting the user experience. However, most security devices and systems are unable to do so. They were built with off-the-shelf processors that were never meant to serve the specialized functions they must do.

Modern Multi-Cloud Security 

Many of the issues a cloud-based security platform faces are the same as those faced by an on-premise solution. It can, however, rely on dynamic scalability to meet performance requirements. However, a multi-cloud security platform optimized using the same engineering processes used to construct a physical ASIC will outperform comparable solutions.

To decrease operational overhead and friction, a multi-cloud security platform must perform reliably in diverse settings with consistent policies. Misconfigurations are still the most common cause of cloud security vulnerabilities; therefore, merely running security on a cloud platform isn’t enough. Security must run natively on each cloud to leverage its unique features. However, while every major cloud platform natively supports only a few security solutions, most businesses employ a multi-cloud strategy. As a result, many of these companies are either using various security solutions in each cloud or using non-native security solutions with limited capability because they cannot fully utilize the platform capabilities where they are installed.

Even if they identify a solution that can function natively in multi-cloud environments, cloud-to-cloud connections are often insufficient. As a result, a security platform must be able to translate functions and policies between clouds. It’s even better if policies are consistent across cloud and on-premises solutions.

Multi-cloud security solutions also enhance end-user security. Mobile and remote users benefit from cloud-based Security-as-a-Service and secure access control. However, this is another example of how adding yet another security solution can not only complicate management and restrict visibility but also reduce a security strategy’s overall efficacy. Cloud-based security services, instead, must be created on the same security platform. This ensures that security policies and enforcement are applied to each transaction from beginning to end.

Bringing Physical and Virtual Solutions Together

One benefit of installing a single security platform throughout the network that runs on a single OS is that it can safeguard interactions between virtual and physical networks. While hybrid networks enable the digital acceleration companies need to compete successfully in the evolving digital marketplace and meet user demand, they also present a significant challenge to anyone attempting to build and manage an efficient security strategy. Building a security architecture that meets today’s demands and can adapt and scale to meet the needs of tomorrow’s network requires starting with a universally deployable and integrated security platform. One that is built for convergence and consistent speed, whether container, on-prem, cloud, or SASE-based.
