Successful Micro-Segmentation: How to Get It Right from the Start

Katey Wood,

Where are you in your segmentation journey? In our polling at RSAC 2019, we found that 50 percent of respondents had interest in micro-segmentation for data center or cloud security in the next year – either learning about it or actively planning for it – or it was already implemented.

There are many reasons you may be considering a micro-segmentation initiative. 

  • SWIFT, PCI, or other regulatory compliance requirements
  • Failed penetration testing
  • Cloud migration
  • Securing a new data center
  • Zero Trust initiative
  • Ringfencing your most critical ("crown jewel") applications or high-value assets
  • It’s a best practice for risk mitigation per NIST's Cybersecurity Framework access control provision.

But where do you begin, especially if you're on a deadline? 

If you've tried starting with traditional firewalls, you're probably already seeking a better solution for segmentation.

If you're looking at segmenting at the hypervisor level, you might be wondering if it meets all your requirements.

And what about the unknowns? Will a micro-segmentation solution meet your future needs – in the cloud, with containers, in any environment – as well as your current requirements?

Here are a few essential resources to help advance your micro-segmentation initiative:

If you're establishing requirements and looking to understand what their peers are seeking, we’ve compiled a list of typical micro-segmentation solution RFP questions in a standard template

Still struggling to build consensus internally? For the "people and process" part of procurement, consult the white paper: How to Secure Your Crown Jewel Applications.

Building a business case to transform your security operations (and get back your weekend)? Check out the new white paper: The Inevitable Costs of Status Quo Security.

Ensure a successful implementation and painless procurement – build your case upfront, gain consensus with your stakeholders, and make sure you have your requirements nailed from the outset.
