How it Works — Netskope SASE w/ Zero Trust Network Access (ZTNA)

The principles of Zero Trust Network Access (ZTNA) are more important than ever as organizations struggle to secure their networks in the digital age. ZTNA is the approach that proves to be one of the most important as companies look to secure sprawling networks securing endpoints without impeding productivity. This blog post details how Netskope SASE (Secure Access Service Edge) reflects The Zero Trust Maturity Model and underpins the importance of this model for threat protection in today’s enterprises.

Zero Trust Network Access (ZTNA) Intro

Zero Trust Network Access is a new approach — given the rise of remote workforces, cloud-based apps and software defined networking — that assumes a threat can emerge from inside or outside your perimeter. This sits in stark contrast to the traditional security models rooted within perimeter defenses, as ZTNA professes a never trust, always verify ethos. It requires very granular checks of each and every user, and their device trying to access resources irrespective of location or network origination. ZTNA reduces the attack surface significantly through these stringent checks which helps protect data from falling into cyber traps.

The core principles of a ZTNA include:

1. Least Privilege — User access rights are restricted to the bare minimum, preventing introduction of any malicious damage by an internal or compromised account.
2. Continuous Verification: Security models enforce continuous verification down to the user identity and device state, so that trust is not just established at the point of entry.
3. Micro-Segmentation: Segments the infrastructure into allotments to prevent lateral movement within the network.

By these precepts, ZTNA offers a comprehensive model for secure network access — an advantage during the time of the remote workforce and cloud-based resources.

ZTNA + SASE = Power to the People

SASE (Secure Access Service Edge) is a more complete cybersecurity framework that consolidates all your network security services, which include ZTNA into a single cloud-delivered solution. ZTNA and SASE are transformative: Each makes the other more powerful in securing enterprise networks, while both enhance security while providing flexible network architecture.

Such security functions, including firewall as a service (FWaaS), secure web gateways (SWG), and data loss prevention (DLP), are by default supported under the SASE framework and make Zero Trust Work as intended with this solution. Combining the two provides a consistent application of security without regard to user location, which is important for wherever any user may be working.

This combination gives companies the following benefits:

• Unified Security Approach: SASE helps extend a unified set of security capabilities to the different distributed environments through security services consolidation.
• Scalability: An enterprise can scale up or down without compromising the security.
• Architected for Simplified Management: Centralized control simplifies the security operations and makes responding to security incidents quicker.

SASE essentially serves as a powerful platform for implementation of Zero Trust principles, ensuring high security standards along with operational efficiency.

Zero Trust in Netskope SASE

One of them is Netskope SASE, they have a complete platform that perfectly meets the Zero Trust security model. This is what Netskope SASE bring to the table in enforcing Zero Trust principles:

1. Identity-Aware Security: Netskope SASE ensures that data is secure when moving to the cloud by using user identity and context in concise access. The Zero Trust principle of ‘never trust, always verify’ is thus followed strictly here to ensure access is constantly validated.
2. Granular Access Control: Our powerful policy engine allows organizations to create policies that grant or revoke access to resources at an extremely granular level based on any distinguishing traits like user role, location, device security posture.
3. Advanced Threat Protection: Netskope uses leading threat intelligence to detect and neutralize malware, as well as other threats in their tracks. Built-in integrations like DLP and SWG, provide complete coverage against data breaches and leaks.
4. Micro-Segmentation and Isolation: Netskope segments networks to reduce the overall lateral movement surface area for malicious actors. This feature contains threats to their source locations and does not allow them to propagate inside the network of an organization.
5. Cloud-Native Architecture — This provides the ability for Netskope SASE to grow or shrink dynamically so it can be scaled based on organizational needs. In addition to that, it can adapt to changes in the digital world and this is crucial for a strong cyber-security in changing times.

Not only does Netskope SASE adhere to these—even other vendors must follow these 7 Zero Trust principles in their business model, but it also strengthens an enterprise’s security posture reducing risk and elevates as a potent solution for cutting-edge businesses.

Zero Trust Network Access (ZTNA) for Enterprise Security Benefits

Various benefits to enterprise security from the implementation of Zero Trust Network Access using Netskope SASE:

• Advanced Data Security: With continuous monitoring of user activities and data flow, Netskope SASE enforces access controls to prevent unauthorized access or data exfiltration.
• Reduced Attack Surface: Micro-segmentation and least privilege access make up for a smaller target area for cyber attackers which leads to an advantage of reducing potential breach impact.
• Increased Compliance: Deploying security measures will also help you comply with the stiff guidelines such as GDPR, HIPAA, and others.
• Agility and Remote Work Enhanced: The rapid implementation of Netskope SASE ensures organizations can safely enable remote workforces to perform without hindrances the lead/agile workforce. Enable your employees work safe from anywhere ensuring business continuity.
• Operational Efficiency: Consolidating a number of different security functions within one solution as the endgame of Netskope SASE reduces complexity by reducing reliance on disparate security tools, thereby translating into cost savings and better operational efficiency.

In short, the Netskope SASE philosophy is Zero Trust Network Access in both spirit and action. With the continued evolution of cybersecurity threats, organizations must consider solutions like ZTNA to protect important data and maintain secure network access. Netskope SASE delivers a solution that provides enterprises with the robust, scalable and efficient capabilities they need to meet these critical demands remains operational anywhere and secure everywhere. Organizations starting at the beginning of their Zero Trust journey or looking to formalize existing practices are well-served by the adoption of Netskope SASE.
