It seems that no matter how many security technologies, network perimeters, and intrusion prevention safeguards are erected, the bad guys somehow find a means of entry.

Enter microsegmentation as a way to minimize the damage from successful perimeter breaches. The basic idea is to segment off parts of the network, especially the most sensitive parts, and wall them off with stricter policies and tie them into a zero-trust architecture.

Microsegmentation improves visibility into data flows and restricts access to applications and data based on approved identities and roles. This makes it far more difficult for cybercriminals to move laterally within a network. Restrictions can also be extended by location and device. Server-to-server, application-to-server, and web-to-server traffic is more closely monitored, with policies preventing all but vital communications between these network segments.

Microsegmentation Benefits

  • Narrowed attack surface
  • Improved threat detection and response times
  • Real-time alerts of policy violations
  • Blocking of unsanctioned activity
  • Strengthened regulatory compliance by creating segments to store regulated and sensitive data such as personally identifiable information (PII)
  • The ability to separate development and production environments

Key Features of Microsegmentation Tools

Vendors in the microsegmentation segment offer a variety of tools and features to make their products attractive, so there are plenty of differences between offerings. Segmentation can also have different levels of granularity. Therefore, each organization needs to determine the level of granularity that is right for a specific environment according to the risk profile of applications.

Despite those differences, these are the features common to most platforms:

  • Visibility into the environments being segmented
  • A comprehensive enforcement mechanism that covers a wide range of compute infrastructure
  • Application and workload identification
  • A strong visualization capability that reveals the “before” in terms of endpoints and communications flows, the “to be” that shows a model of proposed security policies, and the “instantiated” that reflects the security policies that have been implemented
  • Automation has a direct impact on the success of a microsegmentation project, both in how long it takes to deploy and configure, and how easy it is to update security policies on an ongoing basis
  • Microsegmentation should address servers and laptops, IoT, mobile, and legacy devices

Best Microsegmentation Tools

Here are our picks for the top microsegmentation tools in this fast-growing emerging market. Biggest of the relative newness of the microsegmentation and zero trust markets, we expect significant consolidation in the next few years – and indeed, there’s already been one merger on this list, Fidelis and CloudPassage.

Illumio

Illumio Core stops attacks by delivering visibility, a policy creation engine, and automated segmentation and enforcement. The company is consistently ranked well by analysts. For example, Illumio was named a Leader by Forrester Research in The Forrester Wave: Zero Trust eXtended (ZTX) Ecosystem Platform Providers, Q3 2020. Illumio is also one of our top security startups and top zero trust companies.

DH2i

DxOdyssey (DxO) is a Software Defined Perimeter (SDP) solution that enables secure, available, per-application connectivity between remote users, edge devices, sites, and clouds. It uses Express Micro-Tunnel technology for discreet and private connectivity between distributed environments. This lightweight software can be installed on any Windows or Linux machine to achieve a zero trust network architecture without the complexities of VPNs, SD-WANs, or direct links.

DH2i Differentiators

  • Eliminates the need for VPNs to establish remote connections
  • DxO enables secure, dynamic end-to-end data tunnels between edge devices, the data center, and cloud for and between Windows and Linux
  • Provides application-level access only to combat lateral attacks
  • Doesn’t make use of a middleman “controller” node to ensure direct, private communication between sites and clouds
  • Uses a patented TCP over UDP technology to enhance security and performance
  • Express Micro-Tunnels have built-in failover and don’t require DNS resolution
  • There are no ACL or firewall rules to maintain, making it easy to install and configure in seconds

Unisys Stealth

Unisys Stealth is software-defined security that simplifies and improves network security and serves as the backbone of a whole-network zero trust strategy. It blankets the organization’s computing environment with one consistent security policy—from mobile phones and desktops, to servers, to cloud, and IoT.
