Deep Observability is Foundational to Zero Trust

Zero Trust is based on three core principles: never trust, always verify, and least-privilege access. These principles are implemented through several practical pillars.

• Identity verification: Every user and device must prove who they are before gaining access.
• Device security: All endpoints must meet your defined security standards.
• Network segmentation: Breaking your Zero Trust network into protected zones around critical assets.
• Data protection: Keeping information encrypted at rest and in transit.
• Application security: Applying secure practices for applications and continuously monitoring for threats.
• Continuous monitoring & analytics: Watch activity and behavior across users, devices, and traffic to reliably enforce policy and detect anomalies.

The Zero Trust security model offers several benefits, such as:

• Enhanced security: Nothing is automatically trusted; everything gets verified first.
• Reduced attack surface: Network segmentation and least-privilege access limit potential exposure.
• Improved compliance: Detailed records show who accessed what and when.
• Faster threat response: Complete visibility lets you detect and respond to threats quickly.
• Cost savings: Prevent expensive data breaches before they happen.
• Remote work support: The Zero Trust architecture protects access regardless of location, making it a good option for distributed workforces.

Building a Zero Trust architecture starts with getting complete visibility into your network. First, you need to understand what Zero Trust is and see where your security stands today. Start by:

1. Mapping out all your assets, users, and how data moves through your systems.
2. Define protect surfaces and access policies based on least-privilege principles.
3. Strengthen identity controls using methods such as multi-factor authentication and adaptive access policies.
4. Segment the network around critical resources to limit lateral movement.
5. Implement continuous monitoring so network activity can be observed and analyzed in real time.
6. Effective Zero Trust implementations depend on security tools that can inspect encrypted traffic and identify threats as they occur.

Deep observability is the foundation that makes Zero Trust security work. You can't verify and protect what you can't see. Deep observability gives you complete visibility into all network traffic, which is exactly what you need to follow the "never trust, always verify" rule. 

It lets you see everything happening on your network, even encrypted traffic, so you can spot suspicious activity. This visibility works across hybrid cloud environments, keeping your security policies consistent no matter where your apps and data live.

Gigamon supports Zero Trust architecture through its Deep Observability Pipeline, which gives you complete visibility into all network traffic across your hybrid cloud setup. The platform captures network traffic, processes it, and sends it to your security tools. 

Gigamon creates network metadata that helps you continuously verify all network activity, which is exactly what Zero Trust requires. The platform's Precryption technology lets you see inside encrypted traffic, eliminating blind spots that could hurt your Zero Trust implementation. This is important for hybrid cloud security, where old perimeter-based approaches don't work well.

Zero Trust architecture is well-suited for hybrid cloud environments where traditional security models struggle. Since hybrid clouds are spread across different locations, the Zero Trust network approach makes perfect sense because it doesn't matter where your resources are located. 

With Zero Trust, you can use the same access controls and verification mechanisms whether your applications and data are on-premises, in public clouds, or in remote locations.
