Zero Trust Security
Zero Trust security segments internal networks and prevents the lateral spread of ransomware and cyber breaches.
What is Zero Trust? Zero Trust eliminates automatic access for any source – internal or external – and assumes that internal network traffic cannot be trusted without prior authorization. As operating models evolve with more employees working remotely, the need for a holistic Zero Trust approach is even more urgent.
“Forrester recently concluded that Zero Trust can reduce an organization’s risk exposure by 37% or more. But it also found that organizations deploying Zero Trust can reduce security costs by 31% and realize millions of dollars in savings in their overall IT security budgets.”
Zero Trust is an essential security strategy
Focusing primarily on perimeter security and firewalls is no longer enough. Many organizations are now adopting the Zero Trust security mindset of “never trust, always verify” to segment internal networks and prevent the spread of breaches. As users move steadily off the campus network to a distributed work-from-home model, Zero Trust must be extended to endpoints to reduce the attack surface. As a result, micro-segmentation has become a foundational component for Zero Trust.
Trust nothing inside
or outside your
perimeter, on or off
your network.
Verify everything – every user and every device – that tries to connect to your systems and applications.
Anticipate breach and focus on preventing ransomware and bad actors from moving laterally inside environments.
This approach shifts the conversation to preventive containment, with a focus on preventing lateral movement between endpoints, between users and data center applications, and inside your data center and cloud environments.
Illumio delivers end-to-end Zero Trust micro-segmentation from the data center and cloud to endpoints to stop the spread of ransomware and bad actors. Illumio protects against lateral movement across users, end-user devices, applications and workloads, network devices, servers, and other infrastructure.
While endpoint-focused security solutions have evolved, ransomware continues to impact enterprises ... Worms such as WannaCry and NotPetya rely on lateral movement to escalate a containable nuisance to a cataclysmic attack. Microsegmentation and focused granular internal controls mitigate this problem and must be deployed as part of a Zero Trust strategy.

3 steps to achieve Zero Trust
-
Discover
Seeing how your users, devices, and apps are connected is a critical first step to Zero Trust, by understanding what’s communicating and what shouldn’t be.
- Use a real-time map to see everything across your endpoints and application flows and identify high-value systems and critical applications.
- Map the connections of sensitive data across users, devices, networks, workloads, and applications to understand what should be allowed to communicate based on least privilege.
- Enable a single source of truth to facilitate collaboration and engage business and IT stakeholders in designing Zero Trust microperimeters and security policies.
-
Define
The next step towards Zero Trust security is to architect optimal micro-segmentation controls with automated policy creation to reduce risk and deployment complexity.
- Define and automate the right level of Zero Trust segmentation controls (from environmental separation to process level) across endpoints and East-West traffic.
- Identify and map segmentation policies based on the exploitability of vulnerabilities and use segmentation as a compensating control when you can't patch.
- Visualize and test policies before enforcement to ensure you don’t break applications while provisioning security at birth in cloud-native applications.
-
Enforce
Enable default-deny policies that are decoupled from your network to enforce effective Zero Trust controls wherever your endpoints and workloads exist.
- Use an allowlist model to ensure that only authorized connections can take place across users, devices, networks, applications, and workload communications.
- Secure data in transit without requiring any changes or upgrade to the existing network infrastructure.
- Continuously monitor and adjust dynamic Zero Trust policies as your environment changes.
- Seamlessly integrate with third-party IT tools to orchestrate adaptive Zero Trust across your on-premises and multi-cloud environments to reduce security silos.
