Zero Trust
Never Trust, Always Verify: Embrace Zero Trust Network Access!
Zero Trust Network Access (ZTNA) is a cutting-edge security model that ensures secure access to corporate resources by continuously verifying user identities and device health, offering enhanced protection against cyber threats in today's dynamic and remote work environments.
What is Zero Trust?
Zero Trust is a security concept pioneered in 2010 by John Kindervag, the former vice president and principal analyst at Forrester Research. Fundamentally, his thinking was that the typical castle-and-moat approach to cybersecurity – whereby external network access is restricted, but internal access is not – had left organisations badly exposed to hackers and breaches.
Since then, the concept has evolved into a holistic approach encompassing various models, solutions and technologies. However, the underlying principle is always consistent: never trust, always verify. In other words, eliminate trust in all users, devices and applications with access to your network architecture.
Zero Trust Features and Benefits
User Validation
Zero Trust mandates limited user access to necessary applications and verifies identities through robust controls such as multi-factor and biometric authentication at each access attempt.
Segmentation
Zero Trust segmentation restricts network access based on user identity and device security posture, ensuring a more secure environment by minimising potential threats.
Device Visibility
In Zero Trust architectures, the security posture of every device is continuously monitored and verified to detect risks, vulnerabilities or anomalies during access requests.
Secure Remote Access
By applying the same trust-based reasoning to every access point, users get a consistent and productive security experience regardless of location, device or application.
Frictionless Authentication
Zero Trust aims to provide users with a streamlined, frictionless, yet highly secure experience when authenticating to your systems and accessing critical cloud applications.
Risk-Based Authentication
Risk-based authentication evaluates potential threat indicators at each login attempt and adjusts security requirements in real time to protect trusted users and frustrate attackers.
How Protos Networks Can Help
Zero Trust encompasses more than just network segmentation. Protos Networks simplifies Zero Trust architectures into three fundamental pillars:
- User and Device Security: Ensuring the trustworthiness of users and devices, regardless of their location, when accessing systems.
- Network and Cloud Security: Safeguarding all network resources, whether on-premises or in the cloud, while providing secure access to all connecting users.
- Application and Data Security: Preventing unauthorised access within application environments, regardless of the hosting location.
There is no single way to implement Zero Trust architecture, and we tailor our deployments to suit the specific organisation. Our Zero Trust solutions often form part of broader security models such as Secure Access Service Edge (SASE) and Extended Detection and Response (XDR), which we provide to our customers.
Zero Trust and SASE
Zero Trust is an essential part of a SASE (Secure Access Service Edge) architecture because it enables a security approach that validates and protects users, devices and applications regardless of their location, aligning with the core principles of SASE to ensure comprehensive and adaptive security across the entire network perimeter.
