Best Microsegmentation software for 2022

Microsegmentation is a network security solution that isolates workloads and governs each one separately using policy-driven, application-level protection. These software solutions use network virtualization to divide and isolate different parts of data centers and cloud workloads, then deploy and protect them separately. 

In addition to reducing visibility, detection, and remediation times, this aids businesses in better visualizing their assets and workloads. It also thwarts invaders from moving across the network. Businesses employ microsegmentation to increase network observability and protection for specific workloads. 

With the implementation of microsegmentation in the digital environment, network security engineers can reduce the attack surface with the help of policy-based security controls. These controls keep applications and workload secure, even if invaders try to penetrate the perimeter defense system. 

In modern networks, microsegmentation is recommended to achieve zero-trust security. Although microsegmentation technology is used for application-level security, the tools primarily focus on creating custom sandboxes, security policies, and isolated workloads.

Why is microsegmentation important?

The changing landscape of technology means that traditional security solutions are becoming less effective at protecting networks from cyber attacks. 

Security has become a primary concern as more businesses embrace digital transformation and cloud adoption to drive the industry forward. Microsegmentation allows organizations to implement a zero-trust approach in existing infrastructure to deliver security tailored to their specific needs.

To ensure effective security, organizations need a distributed, extended internal firewall built to protect east-west traffic—one that can easily allow network segmentation and microsegmentation of all applications. 

By itself or as part of a zero-trust approach, segmentation divides the data center infrastructure into smaller zones, allowing better control and visibility of traffic flows between workloads.  

Benefits of microsegmentation

Organizations that have adopted microsegmentation have realized numerous tangible benefits.

Restricted lateral movement

Microsegmentation significantly reduces attack vulnerability, so an attacker will find it more challenging to switch from one compromised workload to another.

Reduced attack surface

Without impeding progress or innovation, microsegmentation offers visibility into the entire network environment. Early in the development cycle, security policy definition can be incorporated by application developers to prevent new attack vectors during application deployments or updates. 

Improved operational efficiency

Microsegmentation helps eliminate standalone firewall appliances and ACLs (Access Control Lists). This means IT teams can create stronger security postures with fewer tools.

More robust regulatory compliance

Security engineers can create security policies to segregate workloads and applications from the rest of the infrastructure. 

Improved breach containment

Security teams may monitor network traffic against specified policies with the use of microsegmentation, which reduces the amount of time it takes to respond to breaches.

Streamlined policy management

Managing firewall policies can be made easier by switching to a microsegmentation architecture. Utilizing a single, consolidated policy for threat detection and threat mitigation as well as subnet access control is an emerging best practice for greater security.

How to choose the right microsegmentation software

A crucial component of network and workload security is selecting the appropriate microsegmentation software. The software you use should provide visibility into data flows and  enable you to regulate that flow throughout your company’s network. 

A good microsegmentation tool should have strong capabilities for monitoring east-west traffic and all communication ports. It should also limit access to critical data and applications, a key function of zero trust security. Then, you can use that tool to implement special security policies for each segment of your network.
