SOPHOS   ZERO TRUST NETWORK ACCESS 

⇒  What is Zero Trust Network Access? 

•  Sophos ZTNA (Zero Trust Network Access)  is a security solution that provides secure access to applications and resources without relying on a traditional VPN. With ZTNA, users are granted access only to the specific applications or resources they need, based on their identity and other contextual information, rather than having access to the entire network. This approach is based on the Zero Trust security model, which assumes that all network traffic is potentially malicious and should be inspected and verified before being allowed.
•  Sophos ZTNA  is designed to help organizations provide secure access to their network resources while also ensuring that access is granted only to authorized users and devices. ZTNA accomplishes this by using a combination of identity-based authentication, micro-segmentation, and real-time policy enforcement. ZTNA can be deployed as a cloud-based service or on-premises appliance and can integrate with existing identity and access management (IAM) systems to provide seamless access to resources.
•  Sophos ZTNA  provides several benefits, including enhanced security, improved user experience, and reduced IT overhead. With ZTNA, users can access their applications and resources from anywhere, without needing to use a VPN or being tied to a specific location. This makes it an ideal solution for organizations with remote or mobile workforces. Additionally, ZTNA provides an extra layer of protection against cyber threats by limiting access to only the necessary resources and validating the identity of users and devices before granting access.

⇒  How it Works Sophos ZTNA 

Sophos ZTNA works by providing secure access to corporate applications and resources through a cloud-based intermediary called the Sophos ZTNA service. When a user requests access to an application, the Sophos ZTNA service verifies the user's identity and device posture, then grants access to the application if the user and device meet the defined security requirements.

Sophos ZTNA uses the following steps to provide secure access:

•  Authentication:  Users are authenticated using multi-factor authentication (MFA) and device certificates.
•  Authorization:  Access policies are applied based on user identity, device posture, and other contextual information.
•  Access:  Users are granted access to applications and resources only if they meet the defined security requirements.
•  Monitoring:  All access is logged and monitored for potential threats and anomalies.

Sophos ZTNA provides secure access to corporate applications and resources without exposing them to the internet, reducing the risk of data breaches and cyber-attacks. It also provides a better user experience by allowing users to access resources from anywhere without needing a VPN or complicated configurations.

⇒  Sophos ZTNA Key Features 

•  Enable Remote Workers  - Remote Access VPN has served us well, but was never designed for this new world.  ZTNA provides a much better alternative for remote access by providing better security and threat protection, an easier more scalable management experience, and a more transparent frictionless experience for end-users.
•  Micro-Segment Your Applications  - With VPN, you’re providing network access.  With Sophos ZTNA you’re only providing specific application access.  Your applications, users, and devices are micro-segmented and with the integration of device health into access policies, and continuous authentication verification, you get much better security.  This eliminates all the implicit trust and the lateral movement that comes along with VPN.
•  Control Access to SaaS Apps  - As an alternative or supplement to SaaS application-allowed IP ranges, you can utilize ZTNA and your Azure AD identity provider to control access to important SaaS applications – blocking denied devices and unauthorized users from accessing important cloud apps and data.
•  Stop Ransomware and Other Threats  - Hackers and attackers are leveraging poorly secured remote systems and VPN vulnerabilities to get a foothold on networks to deploy ransomware. Sophos ZTNA helps reduce the surface area and risk of a Ransomware attack by removing a new and growing vector.  With ZTNA remote systems are no longer connected “to the network” and only have specific application access.
•  Onboard New Apps and Users Quickly  - Sophos ZTNA is much leaner, cleaner, and therefore easier to deploy and manage than traditional remote access VPN. It enables better security and more agility in quickly changing environments with users coming and going - making day-to-day administration a quick and painless task and not a full-time job.
•  Secure RDP Access  - Remote Desktop Protocol is a common tool for remote workers and administrators – but is also one of the most common vectors of attack by bad actors.  ZTNA can shield your RDP systems from attacks and provide secure access only to authorized users and devices, including new passwordless options with Microsoft Windows Hello for Business that further helps secure important credentials from possible compromise.

⇒  Top Six Advantages of ZTNA 

Zero Trust Network Access (ZTNA) is a security framework that provides secure access to resources based on the principle of "never trust, always verify." Here are six advantages of ZTNA:

 Improved Security:  ZTNA provides a higher level of security compared to traditional VPNs and other access methods by implementing a more granular and contextual access control system.

 Enhanced User Experience:  ZTNA uses a more user-centric approach that allows users to access resources from anywhere, on any device, without compromising security.

 Reduced Risk of Data Breaches:  ZTNA mitigates the risk of data breaches by ensuring that only authorized users and devices have access to resources.

 Cost Savings:  ZTNA reduces the cost of managing and maintaining VPN infrastructure, hardware, and software licenses.

 Simplified Access Management:  ZTNA provides a centralized platform for managing access to resources, making it easier to manage user access and permissions.

 Compliance:  ZTNA helps organizations meet regulatory compliance requirements by providing a more secure and auditable access control system.
